Job description

About the Role

We are looking for a Founding Engineer with 1+ years of professional experience shipping to production to join our early-stage team. We are seeking a high-agency, first-principles thinker who thrives in ambiguity and wants real ownership, ideally someone who aspires to be a founder someday. This person will play a pivotal role in building our core agent infrastructure, shaping our technical strategy, and helping us scale aggressively as we push toward Series A.

What You'll Do

  • Design, build, and operate core infrastructure powering our people-data and agent platform, including APIs, LLM-powered workflows, 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 founding leadership on technical decisions, roadmap priorities, and foundational architectural choices that will define the company's long-term direction

  • Contribute broadly across the stack and the company, including developer documentation, technical tutorials, internal tooling, and experimental builds that showcase and stress-test our APIs
