About the Role
Join a small, high-ownership engineering team at a seed-stage people data and AI infrastructure company building one of the world's largest real-time identity graphs. You'll work across backend, data, and infrastructure surfaces to ship customer-facing products and core platform capabilities — taking ambiguous problems all the way from concept to production.
What You'll Do
-
Build and ship customer-facing products and platform capabilities spanning backend services, data infrastructure, and frontend surfaces.
-
Design and operate high-volume data pipelines and services at massive scale with a strong focus on reliability, security, and observability.
-
Build AI agents, agent harnesses, and developer tooling — then own and operate them reliably in production at scale.
-
Make architecture decisions, articulate tradeoffs clearly, and iterate designs as requirements evolve.
-
Work directly with founders and customers to translate vague requests into clear product decisions and working software.
What We're Looking For
-
1–6 years of software engineering experience, ideally at an early-stage startup (seed through Series A/B) shipping across both product and infrastructure.
-
Demonstrated end-to-end ownership of a production system — from initial concept through deployment and ongoing operations.
-
Strong backend engineering fundamentals: APIs, data modeling, and distributed systems.
-
Hands-on experience building and operating high-volume data pipelines.
-
Strong CS fundamentals, preferably from a rigorous academic background.
-
Experience with AI-native development: LLMs, agent frameworks, and AI agent systems.
-
Familiarity with identity resolution, data enrichment, or entity-matching systems is a plus.
-
Comfortable using modern AI development tools aggressively while maintaining sound engineering judgment.
-
Available to start by mid-September 2026.
