Senior Product Engineer (Full-Stack)

About the role

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 systems and data modeling.

Responsibilities

• 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.

Requirements

• 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), and 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.

• Familiarity with cloud-native architecture (GCP, serverless, containers).
• Experience designing systems that balance real-time UX with async processing.
