Build and scale the core platform and new zero-to-one initiatives. Translate novel LLM capabilities into understandable, performant end-user experiences. Release production code under a "You Build It, You Run It" ownership model — shipping, operating, and iterating end-to-end. Work directly with enterprise customers (financial crime and risk teams) to solve critical compliance problems. Build integrations, data infrastructure, and tooling to enable AI agents to automate compliance workflows. Evolve schemas and structure non-deterministic LLM outputs for reliable downstream use. Lead customer calls and take ownership of customer outcomes. Collaborate with the founding team to mature engineering practices. Tackle scaling challenges, navigate ambiguity, and help hire and onboard future teammates. What We're Looking For Required: Strong track record building production software, ideally at early-stage startups or on founding teams. Hands-on experience with the core stack: Node.js / TypeScript, Python, React, and AWS Serverless . Practical expe
