Founding Software Engineer

$200k - $225k

Career Renew

Job Description

Job Description

Career Renew is recruiting for one of its clients a Founding Software Engineer - this is an onsite role in San Francisco. Salary range: 200-225K USD base plus benefits plus equity.

We are looking for a Founding Software Engineer with 0-8 years of experience to join our founding team and help build AI systems that control enterprise spend at scale. You'll work alongside former early leaders at Zip ($2.2B procure-tech startup) to solve complex data problems for F500 customers: think dirty data, massive volume, and real bottom-line impact. This is not a flashy consumer AI play; it's a deeply technical, enterprise-grade challenge backed by $5M from 8VC and Jeff Lawson (Twilio founder). If you want to found a company in the future, this is the perfect training ground.

What will you be doing?

  • Building and shipping full-stack product features end-to-end as a core member of the founding engineering team

  • Solving hard data problems at scale: continuously verifying what enterprises have negotiated vs. what they've paid across massive volumes of dirty data

  • Making strategic product and technical decisions that shape the company's direction from day one

  • Working directly with enterprise customers (F500s in CPG, retail, healthcare) to understand their problems and deliver solutions

  • Contributing to AI/LLM systems that drive millions in savings for the world's largest organizations

Requirements:

Impressive, relevant work history at top-tier companies: FAANG, brand-name tech (Airbnb, Figma, Datadog-tier), or Series A/B+ startups backed by reputable VCs

Excited about working in a  deep enterprise B2B / procurement space : solving dirty data problems at massive scale for F500s

0 - 8 years of experience in full-stack software engineering

Full-stack, front-end, or back-end product engineering experience shipping real products (leaning either direction is fine)

Top CS program required for  new grads

Full-stack application development (shipped real products end to end)

Nice-to-have:

Former founder or founding engineer at a reputable, VC-backed startup (highest-caliber profile)

Experience with modern LLM systems, evals, or frameworks

Enjoys talking to and helping enterprise customers

Culture fit with a 25–28 year old founding team (early-career, high energy, wants to build 0-1)
