About the job

Job Title: Staff Full Stack Engineer – Tech Lead (Platform)

Salary: $275K – $300K base + competitive equity

Company Description: Sequoia-backed AI enterprise SaaS — $0 to $10M ARR in under a year, SF

Job Description:

Join a 40-person team that's fundamentally changing how enterprises make decisions. This company built an autonomous AI research platform trusted by Fortune 500 companies across tech, consumer, and retail. As a founding Member of Technical Staff focused on platform, you'll be a key technical decision-maker owning complex systems end-to-end: infrastructure, backend, and product UX. This is a seat at the table, not a seat in the queue.

Location: San Francisco, CA (3 days/week in-office) | Visa sponsorship available (O1, H1B transfer, H1B1)

Why this role is remarkable:

• Step into a founding-level seat at a company that went from $0 to $10M ARR in under a year, backed by one of the most storied institutional VCs in Silicon Valley, with customers that include globally recognized Fortune 500 names across tech, consumer, and retail
• Work alongside serial entrepreneurs, former co-founders, and engineers from elite quantitative trading and infrastructure backgrounds who push systems to their limits every day
• Own the hardest platform problems at a critical inflection point, with founding-level equity on the table for the right person joining now

What you will do:

• Lead the design and implementation of large, high-impact platform projects, and owning systems end-to-end across infrastructure, backend, and product UX
• Define the technical roadmap for major initiatives, make the hard architectural calls, and mentor the engineers around you to raise the quality bar across the org
• Build in TypeScript with either Python/Go (backend-leaning) or React/JS (frontend-leaning) depending on your tilt and ship fast in a lean, high-output environment

The ideal candidate:

• 9-12 years of full-stack engineering experience with proven end-to-end platform ownership at a high-growth startup or top-tier tech company. OR previous co-founder, VP Eng, or founding engineer experience strongly preferred
• CS degree from a top-25 US undergraduate program; deep expertise in TypeScript and either Python/Go or React/JS
• Clear communicator who can articulate tradeoffs without bureaucracy
• A builder who thrives at the 0→1 stage, loves mentoring other engineers, and has spent the majority of their career in early-stage, high-velocity environments not siloed big-tech orgs
