About the Role
This 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 infrastructure company. You will work directly with founders and customers to turn ambiguous problems into shipped, production-owned software. The role spans backend, data, infrastructure, and frontend surfaces at massive scale.
What You'll Do
-
Build and ship customer-facing products and core platform capabilities 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 change.
-
Work directly with founders and customers to turn vague requests into clear product decisions and working software.
-
Use modern AI tools aggressively while maintaining strong engineering judgment and accountability.
What We're Looking For
-
1 to 6 years of relevant professional engineering experience.
-
Strong CS fundamentals, ideally from a rigorous academic background.
-
Proven experience owning a production system end-to-end, from concept through deployment and ongoing operations.
-
Strong backend coding skills: APIs, data models, and distributed systems.
-
Experience at an early-stage startup (seed to Series A/B) shipping across both product and infrastructure.
-
Experience building and operating high-volume data pipelines.
-
Hands-on experience with AI-native development: LLMs, agent frameworks, and related tooling.
-
Familiarity with identity resolution, data enrichment, or matching systems at scale is a plus.
-
Compensation expectations aligned with a base salary up to approximately $220k.
