We're building Percy, the AI agent that runs financial crime investigations end to end. Compliance teams at banks and fintechs are drowning in financial crimes investigations. Transaction volumes are surging, regulators keep raising the bar, and the work still runs on manual review queues that take hours and are stitched together from legacy vendors. We believe AI will make most of these decisions within a few years, so we built Percy to handle them. Percy learns each team's procedures and makes the same calls their analysts would: clearing false positives, escalating real risk, writing the case narrative, and documenting every decision for audit. It cuts review workloads by 70%+ and routinely catches fraud that human reviewers miss. Percy is only possible because of the identity platform we've spent four years building underneath it. Because we own the entire identity flow, Percy resolves ambiguity at the source, running its own checks across our verification tools before a case ever reaches a human. We're backed by QED, Index, Box Group, and Lerer Hippeau, and trusted by companies like Bilt, Nuvei, and MoonPay. We 5x'd revenue last year and plan to do it again in 2026. The team is small, senior, and ships fast. THE ROLE We're looking for a product-minded senior fullstack engineer who can own features end to end, from the API and infrastructure underneath to the polished UI on top. You'll build secure, scalable systems where correctness, security, and performance matter, and you'll sweat the product and UI details that make them great to use. You'll report directly to the Head of Engineering. WHAT YOU'LL OWN - End-to-End Feature Ownership: Own product features from spec → API → UI → deploy → iterate. - API & Service Design: Design and develop high-performance APIs and services that power the Footprint platform. - Polished Frontend: Ship user-facing features with a high bar for UI quality, partnering closely with design. - SDK Development: Contribute to our SDKs so external developers can integrate seamlessly. - Platform & Infrastructure: Improve CI/CD, releases, monorepo tooling (pnpm), performance, and observability across the stack. - Secure Systems: Build services that handle sensitive data securely and correctly (our backend is in Rust). - Product Vision: Be a strong contributor to overall product direction and team planning. MUST-HAVE - Strong product mindset: Ships end-to-end, prioritizes outcomes, and makes smart tradeoffs. - Security-first mindset: You care about privacy, security, and trust, and it shows in how you architect systems. - Systems thinker: You design for scalability and security from day one, not as an afterthought. - High bar for UI quality: Attention to detail, solid design sense, and strong collaboration with designers. - Clean code: Writes maintainable, readable code and can lead technical decisions without over-engineering. - Sweats the details: You think about edge cases, failure modes, and the not-happy path. - Bias to action: You're not afraid to make mistakes, you move quickly yet diligently to get things done. - Low ego, high ownership: You thrive in a high-trust environment where everyone pulls their weight. - AI-native: Uses AI thoughtfully and effectively, leverages AI to move faster and improve quality, while validating results and keeping high engineering standards. NICE-TO-HAVE - Familiarity with the KYC & identity verification space. - Background with real-world cryptography or systems security. - Experience with (or interest in learning) Rust. - Experience with cloud infrastructure at scale: AWS and Pulumi. STACK Rust, TypeScript, Postgres, NextJS/React, Tailwind, React Query, Pulumi, AWS, Vercel SUCCESS LOOKS LIKE - 90 Days: You've shipped meaningful features across the stack, demonstrated ownership of a product area, and built trust with the team through reliable delivery. - 1 Year: You've architected and delivered major platform and product capabilities end-to-end, become a go-to person for technical decisions, and elevated the team's engineering standards. WHY JOIN FOOTPRINT - Massive impact, fast: You'll work on projects that shape company direction, not analysis that gets shelved. - Own meaningful work: From day one, you'll have direct ownership over strategic initiatives that drive the business forward. - Real growth opportunity: Promotion timelines depend on performance: the harder you work, the quicker you'll get promoted. - Winning team and culture: We're a fast-moving, no-BS team that likes to win (and have fun doing it). BENEFITS - 💰 Generous compensation and equity packages - 🍽 Free lunch and dinner (after 7pm) - 💪 Monthly wellness stipend - 🏖 Unlimited PTO - 🏥 Fully covered health, dental, and vision insurance - 🚀 The chance to help shape the future of internet identity and financial crime prevention
