Member of Technical Staff

Member of Technical Staff

San Francisco, CA · Full-time · In-person

For exceptional builders who don't fit in a box

Former founder? Research engineer? Generalist who's been the secret weapon on every team you've joined? This is the role. Member of Technical Staff means one thing at Sourcerer: you can take an impossibly ambiguous problem — "underwrite any supplier in China," "make an agent negotiate a purchase order" — and come back with a working system.

You will work across everything: agents, data infrastructure, product, and whatever the mission demands this month. The ceiling on this role is wherever you take it.

What you'll own

• Whatever matters most right now — agent workflows, search and scraping infrastructure across a dozen-plus countries, underwriting models, customer-facing product

• The full loop — prototype fast, prove it with real customers, then harden it into production

• Your own trajectory — MTS here has grown into engineering leadership, AI leadership, and staff-level IC paths. The role becomes what your work earns.

Who we're looking for

• Exceptional technical ability — we care about what you've built, not how many years you've existed
• Serious experience with modern AI tooling (LLMs, agents, evals) and/or hard systems engineering
• Maximum agency: you find the problem, you solve the problem, you tell us about it after
• You want the earliest seat possible at a company that already has real revenue and real enterprise customers

What you get

• Competitive salary + early-stage equity calibrated to what you bring
• Full benefits (health, dental, vision)
• The most leverage-per-person you will find anywhere: small team, huge market, direct line to founders and customers
