Product Engineer

Job description

About the Role This is a founding-team product engineering role at a Berlin-based, pre-seed AI-native fintech startup building autonomous agent infrastructure for private market operations — think fund accounting, treasury, transfer agency, and reporting. You'll design and build the operational interfaces through which private-market teams interact with AI agents: review screens, exception-handling flows, approval workflows, and the design system that ties it all together. You'll be joining a small, high-caliber team at an early stage, with direct influence over product direction, architecture, and the UX patterns that make AI agent output trustworthy and easy to act on. The company operates in a space similar to Bolo AI and FurtherAI, targeting asset servicers and asset managers looking to automate complex back-office workflows end-to-end. What You'll Do Develop and own the company's design system and shared UX patterns across the product Build purpose-built product interfaces that connect operations teams to AI agents and underlying data sources (ERPs, banking systems, email, portals) Implement human-in-the-loop flows for reviewing, approving, and acting on AI agent outputs — surfacing edge cases clearly and routing them to the right people Design and build exception-handling and review screens that are intuitive within complex operational contexts Conduct user research with operations teams to identify pain points, validate design decisions, and continuously refine product features Collaborate closely with co-founders and cross-functional teammates in a fast-moving, small team environment What We're Looking For Required: Proficiency in modern frontend development with React and TypeScript (Tailwind CSS experience is a plus) Demonstrated experience designing and implementing design systems and reusable UI component libraries for product interfaces Hands-on experience building human-in-the-loop UX for AI/ML workflows — you understand what makes agent output feel trustworthy and auditable Ability to design and build review and exception-handling flows within complex, data-dense operational interfaces Strong communication and cross-functional collaboration skills — you're comfortable working directly with founders and end users alike 1–7 years of relevant product engineering experience Nice to Have: Background in fintech, fund operations, or enterprise SaaS…
