Founding Engineer & Head of Engineering in San Francisco

Job DescriptionJob DescriptionAbout the Role

This is a rare founding-level engineering leadership opportunity at a seed-stage AI agent marketplace. As Founding Engineer & Head of Engineering, you'll own the full technical vision — from agent infrastructure to full-stack product — while building hands-on alongside a small, fast-moving team. You'll be early enough to define the engineering culture, practices, and standards that shape the next 50 hires.

This role is on-site in San Francisco, CA. Candidates must be eligible to work in the United States without visa sponsorship and must be local or willing to relocate.

What You'll Do

• Own the agent infrastructure and the full stack end-to-end (React/Vue frontend, Go/Node.js/Python backend, MySQL, Redis).

• Make the big architecture calls: database design, scalability, uptime, and system reliability for a production platform.

• Build AI-assisted engineering into team culture — establish prompt libraries, skill templates, and code-review standards so the whole team benefits.

• Engage directly with users to distinguish technically sound ideas from ones that only sound good on paper.

• Set the engineering direction and culture as the team scales — your decisions today become the foundation for future hires.

What We're Looking For

Required:

• Proven track record of shipping a product or system 0→1 — end-to-end, from concept to production launch.

• Experience leading engineering teams or setting engineering direction at a founder-stage or early-stage startup.

• Hands-on full-stack capability: frontend (React or Vue) and backend (Go, Node.js, or Python), plus solid database experience (MySQL, Redis).

• Comfort designing scalable architectures, database schemas, and systems with real uptime and scale requirements.

• Eligible to work in the United States without visa sponsorship.

• Able to work on-site in San Francisco, CA (local candidates or those willing to relocate).

Nice to Have:

• Previous experience shipping an AI- product or initiative.

• Active contributions to open source projects.

The Opportunity

The company runs an AI agent marketplace where agents compete to complete tasks, backed by Tier 1 VCs and a strong network of angels with deep expertise in AI and decentralized infrastructure. The platform already has a meaningful and growing user base. You'd be joining at a pivotal moment — early enough to leave a lasting mark, but with real traction behind you.

This role is best suited for someone who wants to do their best work on something that will genuinely get used — not just shipped and forgotten.

Location & Work Arrangement

• On-site: San Francisco, CA (relocation or local required)

• Visa sponsorship: Not available — candidates must be authorized to work in the United States
