About the RoleThis is a high-ownership engineering role on a small, fast-moving team building core platform capabilities and customer-facing products at a seed-stage people data and AI company. You will work directly with founders and customers to take ambiguous problems from concept through deployment, owning systems end-to-end in production at massive scale.
What You'll Do- Build and ship customer-facing products across backend, data, infrastructure, and frontend surfaces.
- Design and operate high-volume data pipelines and services with strong reliability, security, and observability.
- Build AI agents, agent harnesses, and developer tools, then operate them reliably at very large scale.
- Make architecture decisions, explain tradeoffs, and iterate designs as assumptions evolve.
- Collaborate directly with founders and customers to turn vague requirements into clear product decisions and working software.
- Use modern AI development tools aggressively while maintaining strong engineering judgment and accountability.
What We're Looking For- 1 to 6 years of relevant professional software engineering experience.
- Strong backend engineering skills: APIs, data models, and distributed systems.
- Proven ownership of a production system from concept through deployment and ongoing operations.
- Experience shipping across product and infrastructure at an early-stage startup.
- Experience building and operating high-volume data pipelines.
- Strong computer science fundamentals, ideally from a rigorous academic background.
- Familiarity with AI-native development: LLMs, agent frameworks, or similar tooling is a plus.
- Experience with identity resolution, data enrichment, or matching systems at scale is a plus.
