Job description

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., * 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.

Requirements

Do you have experience in TypeScript?, 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 Francisco 5 days per week; relocation is required.

Nice to Have:

  • Previous experience as a founder or early-stage engineer at a startup.
  • Familiarity with distributed systems, microservices, data pipelines, or cloud infrastructure (AWS/GCP).
