Role Description We’re looking for a Senior Product Engineer (Full-Stack) who can own complex, user-facing systems end-to-end, from product definition and UX trade-offs to backend architecture and data modeling. This is not a role for specialists who only live in one layer. You should be comfortable working on: - Frontend UX - Backend systems - APIs - Data schemas and making pragmatic decisions that balance: - Product velocity - Scalability - Long-term maintainability You will work closely with the founders to design, build, and evolve core AI-powered workflows, and act as a technical and product multiplier for the team. What You’ll Do - Own complex product features end-to-end, from product concept → UX → backend systems → production launch. - Design and build scalable backend architectures, including APIs, async pipelines, and AI inference workflows. - Lead system design for new features, including performance, reliability, and extensibility considerations. - Design clean, scalable data models across multiple storage systems (SQL & NoSQL). - Build high-quality frontend experiences using React / Next.js with strong UX and performance sensibility. - Make informed trade-offs between speed, correctness, and scalability, and explain those trade-offs clearly. - Partner closely with Product, Design, and GTM to translate user needs into technical solutions. - Mentor junior engineers and raise the overall engineering bar through code reviews and technical guidance. - Act as a senior technical voice, influencing architecture, tooling, and engineering best practices. - Occasionally represent engineering decisions externally or act as the CTO’s delegate when needed. Qualifications - Strong Full-Stack engineering experience shipping production systems at scale. - Proven ability to design and implement end-to-end features independently. - Excellent system design skills, you can reason about APIs, services, data flow, and failure modes. - Strong experience designing data schemas and data models for real product use cases. - Hands-on experience with multiple database types, such as: - Relational databases (e.g. PostgreSQL, MySQL) - NoSQL / KV stores (e.g. Redis, Firestore) - Solid backend experience with Node.js and/or Python, including async workflows and integrations. - Strong frontend skills with React / Next.js, and an eye for product polish. - High product intuition, you think in user flows, not just endpoints. - Ability to operate with ambiguity and define problems before solving them. Requirements - Nice to Have: - Experience working on AI-powered or data-heavy products. - Familiarity with cloud-native architecture (GCP, serverless, containers). - Experience designing systems that balance real-time UX with async processing. - Prior startup experience or experience owning large surface-area features. Tech Stack You’ll Work With - React / Next.js - Node.js - TypeScript - Python - GCP - Cloud Run - Modal - Firebase - Redis - Upstash Compensation - ~$300k total compensation including base salary, bonus, equity - Equity - meaningful ownership in what you build - High autonomy, high growth environment Work Setup - Bay Area preferred (hybrid allowed) - Visa sponsorship available - We’ll consider remote What Success Looks Like in 3–6 Months - You’ve shipped multiple features that users love. - You’ve launched at least one AI-powered user flow end-to-end. - You’ve formed a tight feedback loop with design, founders, and real users. - You’re pushing ideas, not waiting for specs. - You're a key voice in shaping the product and engineering roadmap.
