You have spent enough time in technical sales to know that the best deals do not come from pitching harder, they come from listening better. You understand that your job is not to sell what you have but to uncover what the customer actually needs and then connect the dots between their problem and the product in your portfolio. You are comfortable walking into a room where the field sales team owns the account relationship and adding value without stepping on toes. You know how to work an overlay model, how to be the product expert without being the hero, and how to make the account team look good while hitting your own number. You are equally at home on a discovery call, a technical demo with an engineer, or a strategy session with a channel partner. You do not need a script. You ask the right questions, tailor the conversation on the fly, and know when to bring in technical support and when to close it yourself. Travel does not slow you down. Neither does ambiguity. You have sold software before, ideally simulation or engineering tools, and you know what good technical sales motion looks like in a complex, multi-stakeholder environment. • Drive direct revenue for EMA 3D, Discovery, MotorCAD, and related product lines by identifying opportunities, qualifying leads, and closing deals in partnership with field sales teams, • Work as an overlay specialist embedded with account teams, bringing deep product knowledge and sales support without owning the full account relationship, • Conduct discovery calls, product demos, and technical presentations tailored to customer workflows, pain points, and buying criteria, • Partner with channel partners and enterprise sales teams to build joint account strategies that expand product footprint and drive renewals, • Coordinate proof of concept efforts and technical evaluations with ACE teams, ensuring customers see real value before they buy, • Attend industry events, trade shows, and customer meetings to build pipeline, strengthen relationships, and represent the product line, • Feed customer insights, competitive intelligence, and feature requests back to product management, marketing, and development teams, • You will directly grow revenue in a strategic product portfolio that powers engineering and design workflows across industries, • Your ability to uncover opportunities in existing accounts will unlock upsell and cross-sell motion that field teams might otherwise miss, • The partnerships you build with channel and field sales will create repeatable, scalable sales plays that outlast any single deal, • Your technical fluency and customer empathy will shorten sales cycles and increase win rates in competitive evaluations, • The feedback loop you create between customers and product teams will shape roadmaps and make the product stronger, • Your presence at industry events and customer sites will raise product awareness and build credibility in the market, • The deals you close will give engineering teams access to tools that solve real problems and accelerate their work, • Bachelor's degree in engineering, business, or a related technical field with 2+ years in technical or software sales, or 4+ years of sales experience without the degree, • Proven track record selling software, ideally engineering applications, simulation tools, or technical products in a B2B environment, • Ability to understand customer workflows and translate technical product capabilities into clear, compelling value propositions, • Comfort working in an overlay sales model where you support field teams and channel partners rather than owning accounts outright, • Strong presentation skills and the ability to demo complex software to technical and non-technical audiences, • Willingness to travel up to 50% for customer meetings, partner engagements, and industry events, • Experience with CRM tools like Salesforce and familiarity with sales processes in a quota-carrying role, • You can walk into a technical conversation with an engineer and hold your own without pretending to be one, • You know how to collaborate with field sales teams without creating friction, you add value and get out of the way, • You are organized enough to manage multiple deals, partners, and product lines at once without dropping threads, • You can explain a complex product advantage in two sentences during a live demo without losing the room, • You do not wait for perfect information to move a deal forward, you work with what you have and ask smart questions to fill the gaps We offer a comprehensive range of health, wellness, and financial benefits to cater to your needs.

We manage the critical path of the user journey from login, to enforcing permissions, to operating within the correct organization and regional context so that the rest of the platform can move fast and stay secure. Within Core IO, the Organizations team owns the data model and platform APIs that define what a customer's account looks like inside Klaviyo and what it is allowed to do. We build and operate the services that power multi-account experiences, enterprise account hierarchies, organization-level lifecycle and policy enforcement, and the onboarding and settings layer for every customer. Our systems are foundational dependencies for nearly every product team at Klaviyo. Why this role is exciting • Shape Klaviyo's enterprise organization platform: We are designing and shipping the multi-level organization hierarchy that large, multi-brand enterprise customers need-platform work that will define how Klaviyo serves its most strategic customers for years to come., • Unlock global scale and compliance: Your work directly supports Klaviyo's international expansion and compliance requirements-including Data Residency for customers worldwide, • Platform-level leverage: The organization and account services your team owns are called by analytics, billing, messaging, identity, and nearly every product surface.

You like building reusable services and internal libraries that raise the floor for correctness and consistency across the organization., • Breadth across the stack: You are comfortable contributing across backend services, internal APIs, and product-facing frontend surfaces. You may have a home base in one layer, but you are not intimidated by the others., • Ownership and collaboration: You take responsibility for outcomes, not just code.

If you're a close but not exact match with the description, we hope you'll still consider applying. Want to learn more about life at Klaviyo? Visit klaviyo.com/careers to see how we empower creators to own their own destiny. Team overview The Core Infrastructure – Identity & Organizations (Core IO) pillar owns the foundational substrate for identity, access, organizations, and platform integrity at Klaviyo. We manage the critical path of the user journey from login, to enforcing permissions, to operating within the correct organization and regional context so that the rest of the platform can move fast and stay secure. Within Core IO, the Platform Anti-Abuse (PAA) team defends Klaviyo's customers, their recipients, and Klaviyo's brand by preventing fraud, abuse, and violations of our Acceptable Use Policy and Terms of Service across all channels. We build the automated detection systems, rules-driven enforcement services, and shared platform tooling that keep Klaviyo's platform safe; and we partner closely with Compliance, Security, and product teams to make "doing the safe thing" the default for every new surface and API. Why this role is exciting • Fight real adversaries at scale: Abuse patterns evolve constantly;bad actors adapt, and so must your systems. You will build detection and enforcement capabilities that respond to emerging fraud patterns across email, SMS, and other channels, combining rules, signals, and ML to stay one step ahead., • Your work is the platform's safety net: The rules engine and enforcement services your team owns are consumed by messaging, campaigns, flows, and nearly every sending channel at Klaviyo. Improvements you make protect millions of email and SMS recipients and directly affect platform trust and deliverability., • Work at the intersection of rules, ML, and systems engineering: This role is unusually broad technically. You will build high-throughput Go services, Python rules pipelines, and integrate ML-based classifiers for content and URL abuse. Few platform roles combine adversarial problem-solving with this range of systems work., • Own features end-to-end across design, implementation, rollout, and observability for abuse detection and enforcement capabilities; rules, classifiers, enforcement pipelines, and the platform services that other teams plug into., • Extend abuse enforcement to new product surfaces: Help bring anti-abuse rules and enforcement to product areas where coverage is currently limited, ensuring consistent policy application across channels., • Build content and link abuse detection systems: Help design and implement detection capabilities for malicious URLs, abusive image content, and other content-level signals;combining perceptual hashing, ML model integrations, and rule-based approaches., • Contribute to AUP automation and enforcement pipelines: Help build and scale the systems that automatically evaluate accounts against our Acceptable Use Policy, reducing reliance on manual compliance review., • Improve platform anti-abuse infrastructure: Evolve microservices, rules orchestration layer, and abuse observability pipelines; making them faster, more reliable, and easier for the team and compliance stakeholders to operate., • Help define and refine standards for how other teams integrate with PAA's detection and enforcement APIs; so product teams can add abuse coverage to new areas without reinventing detection logic per service., • Collaborate closely with partner teams: Work with Identity & Access Management (IAM) on authentication & authorization signals, with Organizations on account lifecycle and policy enforcement, and with Security and Compliance on AUP/TOS enforcement patterns., • Experienced systems builder: You have 2-5+ years of professional software engineering experience, including building and operating backend or full-stack services in production., • Strong fundamentals and debugging skills: You are comfortable reasoning about data models, API design, concurrency, and failure modes, and you can dig through logs, metrics, and traces to identify root causes and implement systemic fixes., • Security and abuse motivated: You are energized by adversarial problem spaces;fraud detection, policy enforcement, content moderation and want to build systems that anticipate bad actors rather than just react to them., • Platform and signal mindset: You think about detection not just as individual rules but as a system of signals, coverage, and feedback loops. You like building shared enforcement APIs and detection pipelines that product teams plug into making abuse prevention a reusable capability rather than something each team reimplements., • Ownership and collaboration: You take responsibility for outcomes, not just code. You are comfortable driving a project end-to-end, coordinating with Compliance and Security stakeholders, and communicating trade-offs clearly in design docs and pull requests., • You've already experimented with AI in work or personal projects, and you're excited to dive in and learn fast. You're hungry to responsibly explore new AI tools and workflows.Minimum qualifications, • 2-5+ years of professional software engineering experience., • Proficiency in at least one of Python or Go, and comfort working on backend and/or service-oriented systems, including web services or APIs backed by relational databases and/or caches (e.g., MySQL, Postgres, Redis)., • Comfort reasoning about detection, classification, or enforcement systems;whether rules engines, content evaluation, or risk signals and the trade-offs between precision, recall, and system performance., • Experience building detection or classification systems; rules engines, content classifiers, anomaly detection, or fraud/risk scoring and reasoning about signal quality, false positive rates, and coverage., • Familiarity with ML model integration in production systems: calling model endpoints, processing outputs in rules pipelines, and monitoring model-driven decisions., • Working with cloud-native infrastructure (AWS, Kubernetes, Terraform, or similar) and building services designed to run at scale., • Exposure to compliance or policy enforcement domains (AUP/TOS enforcement, content moderation, fraud detection) and how platform decisions in these areas are made and measured., • Familiarity with observability stacks (Grafana, Datadog, Sentry, Splunk) and using them to drive reliability and detection-quality improvements., • Languages & frameworks: Python, Django, Go., • Infrastructure & platform: AWS, Kubernetes, Terraform, rules engine and enforcement service platform.

Job Description About Stackpoint Stackpoint is a venture studio that conceives, builds, launches, and scales AI-native companies in high-barrier verticals like real estate, construction, hospitality and financial services. Led by co-founders who have both built unicorn real estate tech companies from scratch, we're a tight team of engineers, product managers, designers, and operators with decades of experience building products, teams, and businesses from startup to scale. We focus all of our energy on discovering and solving customer and business problems, designing financially strong and defensible business models, activating growth engines, hiring world-class founding teams, and helping them thrive (and none of our energy on big-company b.s.). Our dedicated capital, experienced team, proven process, and deep strategic network supercharge founders and accelerate growth. We're based in Boston but have a distributed team, work remotely and come together every quarter for in-person team building. We're building a pooled, Studio-wide engineering team — and we're looking for principal-level engineers who want to build across an entire portfolio of companies, not just one. The Role Context - How the Studio operates: We launch one new company per quarter. For each, we embed a pod — a dedicated PM, Designer, and one or more Studio Engineers — for ~6 months alongside a founding CEO we recruit and back. The first three months focus on discovery: identifying the wedge product, assessing technical feasibility, and accumulating design partners. The second three months shift to building the wedge while hiring the company's founding technical team (Head of Engineering, sometimes 1-2 IC engineers or contractors) in parallel. Because launches are staggered quarterly, at any given time the Studio is hands-on in ~2 companies at different stages. Shared resources across Marketing, Sales, Finance, Ops, and Recruiting flex across companies during the first 6-12 months based on what's needed to hit key milestones. As a Principal Engineer, you are the person who builds. You'll typically embed with a single portfolio company for several months at a time — architecting, coding, and shipping backend systems and responsive frontends from prototype through MVP launch. As that company graduates to its own engineering team, you'll roll onto the next build, bringing compounding experience across domains and tech stacks. You'll partner directly with PMs, designers, and founding CEOs to turn discovery insights into functional software. This is a hands-on, full-stack IC role. You'll report to the Studio's Head of Engineering and you'll be expected to own entire product surfaces end-to-end: cloud infrastructure, APIs, data pipelines, UIs, and deployment — often on the same product. Technology choices are problem-driven, not preference-driven, and you articulate tradeoffs clearly. AI-native development is core to how you work. You use tools like Cursor and Claude Code daily, you've integrated LLMs into production systems, and you have hands-on experience with prompt engineering, structured outputs, and cost/performance tradeoffs. You follow the AI landscape actively and make pragmatic adoption decisions. What You'll Do Full-Stack Product Development Architect, build, and ship backend systems and responsive frontends for new products across our portfolio, from prototype through MVP launch. Infrastructure and DevOps Set up and manage deployment environments, CI/CD pipelines, logging, and monitoring for new builds using modern cloud or hosted tools. Make pragmatic decisions that prioritize speed and reliability in early-stage systems. AI-Native Development Leverage AI coding assistants as core workflow tools to accelerate building, iteration, and experimentation. Integrate LLM-powered features into customer-facing systems where they create real value — including agentic workflows, structured outputs, retrieval patterns, API integration, and evaluation of model tradeoffs. Deep Engagement, Then Rotation Embed with a portfolio company for the duration of its Studio-led build (typically ~6 months). Own the technical execution alongside the pod. When the company transitions to its own team, roll onto the next build with fresh context and compounding experience. Product Collaboration Partner with PMs, designers, and founding CEOs to translate discovery insights into functional software. Contribute to feasibility assessments and help teams understand what's buildable, what's risky, and what's worth a "build to learn" bet. Technical Transition Support Help portfolio companies hire their own engineering teams (Head of Engineering, senior ICs) and execute clean handoffs of Studio-built systems within ~6 months of launch. Studio Tooling and R&D Contribute to internal tools and reusable frameworks that create compounding leverage across the Studio's portfolio companies. What We're Looking For Experience and Background • 5+ years of software engineering experience with meaningful exposure to modern product/engineering cultures and varied company stages, • Building in early-stage 0→1 environments (seed to Series A), operating in high-ambiguity settings and contributing from concept through launch, • Agentic AI: Experience building AI-driven workflows in production (orchestration, tool-use, multi-step reasoning). You know how to make LLM-powered systems reliable in real-world B2B contexts—not just prototypes (structured outputs, retrieval patterns, prompt design, and model tradeoffs)., • Data Pipelines: Experience ingesting unstructured or messy data sources (PDFs, documents, web scrapes, APIs) into vector stores (embeddings) and databases (Wide column stores, SQL/NoSQL) for downstream AI queries (semantic search)., • 0→1 Building: You've taken products from "blank page" to production launch—not just features within established products. You've built and shipped from concept through launch and early iteration in early-stage or startup environments. You architect for the long term, but optimize for rapid learning and execution in the early build phase., • Full-Stack Ownership: You are proficient in the modern stack (Python/Node + NextJS/React/Vue.js) and can take a build from local development to production deployment using modern cloud or hosted infrastructure., • Secure Architecture Principles: Understanding of software and AI attack surfaces, secure coding, and handling of PII or sensitive data in regulated industries., • Experience with Multimodal AI in production systems (image/video/voice understanding and/or generation), • Context-switching is a feature, not a bug. You find variety energizing and ramp fast into new domains, codebases, and team contexts, • Speed and pragmatism define your output. You understand the difference between "build to learn" and "build to scale" and make that call explicitly, • You operate on the frontlines of product work. You're a strong cross-functional collaborator engaging with customers, PMs, designers, and stakeholders in early discovery cycles (onsites, interviews, feedback loops), and using those signals to shape technical and product decisions—not just execute requirements, • You're user-led in your thinking but bold enough to advocate for technical bets when you see an opportunity, • You're driven by craft and impact, not title or territory. You care about quality but aren't precious — you'll throw away a prototype without flinching if the team learns something important, • You're low-ego, generous with knowledge, and someone other engineers want to work withWhy This Role Is Different, • Breadth over depth: You'll touch more industries, domains, and technical challenges in a year than most engineers see in five. Real estate, insurance, construction, finance — each portfolio company is a new problem space., • Build, not maintain: Every engagement is a greenfield build. You're always working on the hardest, most interesting phase of a product's life — the 0→1., • A real team, not a solo act: You'll work alongside a small, high-caliber engineering team — plus PMs, designers, and operators — who are collaborative, low-ego, and deeply experienced at building from scratch. This isn't a lone-wolf contractor gig; it's a tight team that learns and compounds together., • Leverage over repetition: Your Studio tooling and R&D contributions don't just serve one product — they accelerate every future company Stackpoint creates., • Direct impact: You'll work directly with founders, the full Stackpoint Studio team, and portfolio company customers. No layers. No politics. Just building.Logistics, • Compensation: Competitive base, comprehensive health benefits + equity participation in every company we launch during your time here., • Location: Flexible within U.S. and Canada— we operate remotely., • Reports to: Studio Head of Engineering.
