Job Description & How to Apply Below
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.
Required:
- 2+ years of experience in full-stack or backend software engineering.
- Proficiency in JavaScript and Type Script.
- 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.
- Previous experience as a founder or early-stage engineer at a startup.
- Familiarity with distributed systems, microservices, data pipelines, or cloud infrastructure (AWS/GCP).
- Salary: $150,000 - $220,000 USD annually, depending on experience.
- Equity participation as a founding team member.
- San Francisco, CA - fully on-site, 5 days per week.
- Relocation to San Francisco is required for this role.
- No visa sponsorship available; must be authorized to work in the United States.
