About the Role
We're a fast-growing, early-stage data infrastructure company building one of the world's largest living identity graphs — spanning billions of individuals — powered by autonomous AI agents operating across the open web. Our 8-person engineering team is looking for a Software Engineer, AI & Data Systems with 1–6 years of experience to build core platform capabilities and customer-facing products.
This is a high-ownership role. You'll take ambiguous customer problems, choose sensible architectures, ship products, and own them end-to-end in production. You're expected to use modern AI tools aggressively while maintaining strong engineering judgment and accountability.
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 at massive scale 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, articulate tradeoffs clearly, and iterate designs as assumptions evolve
-
Work directly with founders and customers to translate vague requirements into clear product decisions and working software
What We're Looking For
Must-haves:
-
End-to-end ownership of a production system — from concept through deployment and ongoing operations
-
Strong backend engineering skills: APIs, data models, and distributed systems
-
Based in or willing to relocate to San Francisco for a full-time, in-office role
-
Experience at a talent-dense early-stage startup (seed through Series A/B) shipping across both product and infrastructure
-
Hands-on experience building and operating high-volume data pipelines
-
CS degree from a top-tier university
Nice to have:
-
Experience building AI agents, data pipelines, or identity/entity matching systems at scale
-
Familiarity with AI-native development: LLMs, agent frameworks, and related tooling
-
Available to start by mid-September 2026 for our residency program
Tech stack includes: Python, distributed systems, data pipelines, LLMs, AI agent frameworks, REST APIs, cloud infrastructure.
Note: Visa sponsorship is not available for this role.
