# Founding Engineer - Company: [Clera]() - Location: San Francisco - Team: Engineering - Employment type: Full Time - Salary: $150K – $220K - Posted: June 3, 2026 ## Job description ### About the Role A seed-stage AI data infrastructure startup in San Francisco is looking for a **Founding Engineer** with 1+ years of professional experience shipping to production. This is a foundational hire at an early-stage company building a people-data and agent platform — you'll have real ownership, work directly with leadership, and help shape the technical direction of the product as it scales toward Series A. Ideal for a high-agency, first-principles thinker who thrives in ambiguity and has founder aspirations. ### What You'll Do * Design, build, and operate core infrastructure powering a people-data and AI 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 the CEO and CTO on technical decisions, roadmap priorities, and foundational architectural choices that will define the company's long-term direction. * Contribute broadly across the stack, including developer documentation, technical tutorials, internal tooling, and experimental builds that showcase and stress-test platform APIs. ### What We're Looking For * **Required:** 1+ years of professional experience shipping software to production. * Hands-on experience with APIs, distributed systems, microservices, and data pipelines. * Comfort working with LLMs, AI agents, and knowledge graph or identity resolution systems is a strong plus. * Experience with cloud infrastructure (AWS or GCP) and Linux server environments. * Strong instincts for performance, reliability, and cost-efficient system design. * High agency — you move fast, take ownership, and operate well with limited direction. * First-principles thinker who is energized by building 0-to-1 in a fast-moving environment. ### Compensation & Benefits * **Salary:** $150,000 – $220,000 USD annually * Early-stage equity as a founding team member * Note: Visa sponsorship is not available for this role ### Location This is an **on-site role based in San Francisco, CA**. Candidates must be available to work in-person. ## Apply [Apply on Clera]() Canonical job page:
