Software Development Engineer in Test (SDET) London Hybrid | Series A AI Infrastructure Startup It is hard to build a reliable system. It is even harder to prove that it is reliable. Our client is redefining how enterprise software is tested. Their AI native platform automates test data, test case generation, and environment provisioning, enabling engineering teams to ship faster while reducing compliance and operational risk. Trusted by Tier 1 banks and global financial institutions, the company has recently completed a successful Series A round backed by leading global investors. With rapid enterprise adoption and a hybrid architecture spanning SaaS control plane and on premises agent data plane, they are now hiring a Software Development Engineer in Test to take ownership of quality engineering at scale. This is a deeply technical SDET position focused on building robust automated systems, not manual testing. Reporting to the Head of Engineering, the SDET will define and own the end to end test strategy across both cloud and agent components. The platform operates across distributed, database heavy, and security sensitive environments, meaning quality must be embedded at every layer of the stack. The successful candidate will design, implement, and maintain multi layer automation across UI, API, contract, integration, and distributed system scenarios. This includes building and maintaining UI automation frameworks using Playwright or Selenium, alongside backend automation in Kotlin or Java using JUnit, Testcontainers, REST assured, or Ktor based tests. A key responsibility will be validating behaviour across multiple database engines including PostgreSQL, MySQL, and SQL Server. The SDET will write complex SQL queries, validate joins and window functions, analyse query plans, and test indexing strategies, transaction handling, connection management, replication topologies, and backup and restore flows. This is a hands on database intensive role requiring strong technical depth. The role also involves building a protocol level test harness for remote agent communication. This includes simulating asynchronous communication, injecting failures, modelling network instability, and running chaos style scenarios to validate resilience under real world conditions. Ensuring agents running inside customer networks remain secure, performant, and compliant is a critical part of the mission. Quality gates and trend reporting will be embedded into the GitHub Actions CI CD pipeline to ensure automated validation on every release. The SDET will also implement observability driven testing practices, leveraging logs, traces, and metrics to detect regressions, performance bottlenecks, and edge case failures that traditional assertions may not capture. Collaboration is essential. The SDET will work closely with Product Managers and Solution Architects to refine acceptance criteria, surface technical risks early, and validate complex enterprise workflows. As the company grows, this role offers a clear progression path toward leading and building out a broader quality engineering function. This opportunity will suit a strong engineer who happens to specialise in testing. Candidates should have hands on experience within cloud native or hybrid architectures and feel comfortable validating distributed systems and asynchronous protocols. Experience with Docker and Kubernetes to spin up realistic test topologies is important, as is familiarity with CI CD tooling such as GitHub Actions. Exposure to observability stacks such as OpenTelemetry, Prometheus, and Grafana will be highly advantageous, particularly where these tools are used to derive intelligent test assertions. Security, compliance, or data privacy testing experience is a plus given the nature of the customer base and the environments in which the platform operates. In return, the company offers a competitive salary, meaningful equity, hybrid working between home and London offices, up to one month per year working from anywhere, generous annual leave including your birthday off, private medical cover, a dedicated learning and development budget, regular team offsites, and strong family leave policies. Above all, this is an opportunity to engineer reliability into mission critical enterprise systems within a high growth AI infrastructure business. If you are an SDET who wants to build sophisticated automation, validate complex distributed systems, and shape quality at the heart of a scaling product, this is a role worth exploring.

Requirements won’t always be fully formed; you’ll be expected to explore problems, test ideas, and iterate fast. This role reports directly to the founder and offers genuine influence over both product and technical direction. What You’ll Do • Build and ship production features from your first week, • Work closely with users to understand pain points and validate solutions, • Help define product strategy in an ambiguous, fast-moving environment, • Design and scale TypeScript-based systems across the stack, • Build AI-powered workflows and agent-based systems that go beyond basic prompting, • Set engineering standards and raise the bar as the team grows You May Be a Good Fit If You • Have experience at early-stage startups and enjoy high ownership, • Think in terms of user problems, not just technical implementations, • Have scaled and maintained complex TypeScript codebases, • Are comfortable working end-to-end across product and engineering, • Actively experiment with and refine AI-assisted development workflows, • Have built LLM-powered systems or AI agents in production environments Tech Stack • TypeScript monorepo, • React, tRPC, Tailwind, • Event-driven workflows and background jobs, • Deployed on Google Cloud Platform, • Postgres What’s On Offer • £100,000 – £150,000 base salary (depending on experience), • Meaningful early-stage equity, • 5% employer pension contribution, • Private medical cover (including dental and optical), • 25 days holiday plus bank holidays, • Choice of AI tooling, • London-based role (Shoreditch), working closely with the founding team

What they need now is someone who’s excited to step up, learn fast, and grow alongside the company. Who are Staxy? Staxy is an early-stage technology startup building products that sit at the intersection of sport, location data, and real-world behaviour. They work with organisations to better understand how people move, engage, and interact with physical spaces, using mobile technology, location data, and analytics to generate meaningful insight.

A pre-seed, founder-led startup is seeking a Founding Engineer to build the "Agentic Financial Ops" layer for the global fintech market. While others build simple chatbots, this stealth-mode venture is embedding autonomous AI agents directly into major B2B platforms—automating invoicing, bill pay, and payroll for SMBs.

What you will build: • The Engine: A white-label, API-first, multi-tenant system designed to embed cleanly and securely into partner ecosystems., • The Intelligence: You aren’t just calling APIs; you are treating LLMs as infrastructure. You will build agentic workflows that handle complex financial operations autonomously., • The Foundation: You will replace the founder’s initial "vibe-coded" prototype with a robust, production-ready architecture. You decide the stack; you set the engineering culture. The Founders: • The Commercial Engine: A domain experts and "straight talkers" (formerly VPs at a successful embedded finance scale-up). They have already secured signed contracts across the UK, US, and Europe—and early revenue—before the API is even live. They bring the pipeline, the deep market knowledge, and the capital; you bring the product. The Role: • Zero to One: Take the product from MVP concept to Production., • Full Ownership: Build the core platform end-to-end (Backend, APIs, Frontend)., • Architecture: Design for security, permissions, and scale from day one., • Speed: Iterate fast with real customers. The goal is to launch the API in Q2. This is not a ticket-taking role at a stagnant SaaS. This is a Decide + Build + Own seat where you sit directly beside the founder. The Profile • Mindset: Scrappy, high-growth, and product-minded. You care deeply about why a feature exists, not just how it’s built., • Experience: A Senior Engineer (Backend-leaning or Full-stack) who has shipped early-stage products into production., • Tech: Hands-on experience with LLMs & agentic workflows. You are pragmatic about tech choices that optimize for speed and correctness. The Offer Salary £95k–£120k + Significant Founding Equity.
