Job Description Company Overview Promise modernizes how government agencies and utilities support people in financial difficulty. We build technology that makes it simple for residents to receive benefits, engage with assistance programs, set up flexible payment plans, and stay on track—while helping agencies increase efficiency, recover revenue, and deliver services with dignity. Our mission is to transform public systems so they work better for everyone, especially the most vulnerable. Our team includes experts from companies like Palantir, Google, Stripe , and esteemed government leaders. We work hard and believe deeply in what we do. We're looking for excellent people to build innovative, resilient technology. Backed by over $50 million in funding from top investors – such as Reid Hoffman, Howard Schultz, Michael Seibel, Y Combinator, 8VC, The General Partnership, First Round Capital, Kapor Capital, XYZ Ventures, and Bronze Investments – Promise has been recognized as one of Fast Company's "World's Most Innovative Companies of 2022,” “Forbes Next Billion-Dollar Startups 2024,” and Y Combinator’s #1 GovTech startup. About the Role We’re looking for a Forward Deployed Software Engineer who’s driven by impact, excited by challenge, and motivated by Promise’s mission: helping low-income families catch up on past-due bills and access the relief they deserve. This is not your typical engineering role. You’ll be on the front lines—working hand-in-hand with utilities and government partners, solving complex integration challenges, and making sure our technology actually delivers where it matters most: in people’s lives. You’ll bring strong technical fundamentals together with empathy, patience, and the kind of customer savvy that turns a deployment into a long-term partnership. Impact in Action In Washington State, Promise distributed $100M of energy aid in just three months, reaching nearly 700,000 households. In Virginia and Florida, we helped ensure millions of dollars in water assistance funds reached families who might have otherwise gone without. Our AI-powered eligibility verification now cuts approval times for programs like SNAP and LIHEAP from weeks to hours.

What Will Help You Succeed * Engineering chops: 4+ years of experience building and deploying production software, with fluency in environments that require adaptability and fast learning. * Customer instincts: Experience in a customer-facing technical role where you balanced empathy with technical rigor. * Tools of the trade: We use JavaScript / TypeScript, ETL tools, SQL, React – you don’t need to be an expert on any of these! You do need to come with a willingness to learn. * Curiosity & grit: You don’t wait for someone to tell you the answer—you explore, experiment, and document so others can follow. * Collaboration: This is a cross-functional role where you will be working across engineering, design, product, delivery, and sales. FDEs work across team boundaries to get things done. Who Thrives at PromiseYou’ll love it here if: * You are energized by big, complex challenges and the opportunity to solve them. * You want your work to have a real, measurable impact on people’s lives. * You take ownership and run toward problems, not away from them. * You value clear, candid, and constructive communication. Promise is not for you if: * You prefer hierarchy and rigid structures. We operate with freedom and responsibility. * You are uncomfortable with change. We move fast, adapt often, and expect agility. * You want a typical corporate culture. We are mission-driven, ambitious, and direct. * You believe efficiency means “doing less.” We believe efficiency means doing better. How We Support Our People * 100% paid health coverage * Generous PTO and sick leave * Lunch, snacks, and coffee provided * Company retreats * Opportunities to travel and see the impact of your work * Hybrid work: we deeply value in-person collaboration and are in-office at least 3 days a week, but are flexible on working from home Promise is an equal opportunity employer and does not discriminate against any applicant or employee because of race, color, religion, sex, sexual orientation, gender identity, national origin, disability, genetic information, age, or military or veteran status.

Job Description Clipbook’s mission: reinvent how leaders listen to and engage the world. We are the vertical AI category leader for the $100 billion communications, public relations, and public affairs industries. Since 2023, we have quietly grown into the largest AI company in this segment. We are backed by leading investors in the segment - including Mark Cuban, who co-led our seed round. A bit more about us: * We bootstrapped to our first million in ARR and hit profitability before raising our $3.3 million seed round this year. * We’re currently growing >10% month-over-month and on track to >3x ARR this year. * We’re working with 200+ clients including the Boston Consulting Group, Weber Shandwick, the Gates Foundation, and dozens of government agencies across the country. * We will raise our Series A in early 2026. What You'll Do * Architect & build. Make architectural decisions and implement solutions across the stack (NextJS, TypeScript, React, Python, Node, SQL/NoSQL). You have the conviction to quickly build from concept to deployment to seeing clients love our product. * Collaborate with customers. Work directly with users to understand pain points, iterate quickly, and deliver solutions that matter. * Tackle a wide breadth of engineering challenges. Our work spans AI, data engineering, backend, etc., so there's plenty of opportunity to find projects that match your strengths and interests. Some examples include: * AI/ML Integration: Productionize LLMs and classical ML models for real-world, high-uptime applications. Leverage the latest in generative AI tooling and frameworks. * Data Engineering: Build pipelines and infrastructure for ingesting, normalizing, and querying massive, multi-modal datasets. * Shape Clipbook’s engineering culture.

We care more about what you ship than when/where you work — but we do believe spending time together in-person (we’re hybrid, in the office 2–3x/week) meaningfully accelerates product velocity and team chemistry. Deep knowledge and practical experience with cloud based services, containerization, and API development * Experience optimizing data architectures for performance and cost. * Strong product sense and bias for action. We’re a small team and can’t afford to be caught in analysis paralysis since we often have to make decisions with incomplete information. * A future leader. We want someone who can quickly grow into engineering leadership at the company. Bonus Points * Experience with any of the following: * LLM fine-tuning, RAG, or RLHF pipelines * Familiarity with web scraping frameworks (Playwright, Puppeteer) and different types of API integrations (REST, GraphQL) * Comfort with asynchronous workflows, rate-limiting, and distributed systems * Experience in early-stage startups or as a technical founder is a huge plus What You'll Get: * Compensation: $180K+, high-upside equity (from a team that understands commercial rigor and bootstrapping to 7-figures: pre-seed dilution but with Series A metrics), and full benefits (medical, dental, vision, 401k, unlimited PTO). * Ownership: Direct influence on product and company strategy.
