Full Job Description

ABOUT THE ROLE A seed-funded B2B SaaS startup in the people-data and AI agents space is looking for a high-agency Founding Engineer to build core agent infrastructure and help scale the platform toward a Series A milestone. You'll work directly with the founding team — including the CEO and CTO — owning critical systems that power a people-data and agent platform used by developers and enterprises alike. This is a rare opportunity to shape technical strategy from the ground up at a fast-growing, well-backed startup. WHAT YOU'LL DO - Design, build, and operate core infrastructure including APIs, LLM-powered workflows, web scraping systems, and large-scale knowledge graph architecture. - Architect and maintain production-grade systems capable of handling millions of API requests, with a strong focus on performance, cost efficiency, and reliability across cloud and Linux server environments. - Own projects end-to-end — from ambiguous problem definition through deployment and iteration — shipping quickly without sacrificing system integrity. - Collaborate directly with the CEO and CTO on technical decisions, roadmap priorities, and foundational architectural choices that define long-term direction. - Contribute broadly across the stack, including developer documentation, technical tutorials, internal tooling, and experimental builds that showcase and stress-test APIs. WHAT WE'RE LOOKING FOR Required: - 2+ years of experience in full-stack or backend software engineering. - Proficiency in JavaScript and TypeScript. - Experience with agent orchestration, LLMs, or web scraping. - Experience working with Linux servers in a production environment. - Proven track record of shipping code to production supporting a large user base. - Experience building entire products end-to-end, not just isolated features. - Strong computer science fundamentals. - Must be authorized to work in the United States — visa sponsorship is not available. - Must be available to work on-site in San Fr
