About the Role
Join an early-stage legal technology team building AI-powered software for contract workflows. As a founding product engineer, you will work closely with attorneys and AI engineers to turn practical legal expertise into reliable software that customers use every day, while helping shape the engineering culture as the team grows.
What You'll Do
Build and own full-stack product features, from data models and backend systems to user-facing interfaces.
Work with attorneys and AI engineers to translate legal workflows and review practices into production-ready software.
Make pragmatic architecture and tooling decisions that support fast delivery and long-term reliability.
Write maintainable code, monitor production quality, and take features through deployment and ongoing ownership.
Help establish engineering standards and contribute to hiring as the team expands.
Work closely with teammates in person to deliver customer-focused product improvements.
What We're Looking For
One to three years of experience building and shipping production software, ideally at an early-stage company or as a founder.
Full-stack development skills, including TypeScript and React, a modern backend stack, and relational databases.
Hands-on experience building with AI or large language models, professionally or through personal projects.
Experience owning features end to end, building data models and user-facing interfaces, and making sound engineering trade-offs under time constraints.
Strong product judgment, communication, and a record of delivering maintainable, reliable software in ambiguous, fast-moving environments.
Legal technology, contract management, document processing, or experience working directly with domain experts is helpful.
Compensation & Benefits
Base salary: $140,000 to $180,000 annually. Visa sponsorship is not available.

On-site in San Francisco, California, six days per week. Relocation to San Francisco is at the candidate's own expense.

Tips for Your Founding Product Engineer Job Search
Show ownership, not just contribution
Founding product engineer roles expect you to have driven decisions end-to-end, not executed tickets. Rewrite your resume bullets to show what you owned, what tradeoffs you made, and what shipped as a result of your judgment specifically.
Apply early to roles that fit
Migrate Mate lists founding product engineer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Target companies at the right stage
Founding product engineer roles at seed-stage companies need generalists who can set architecture. Series B roles want someone who can scale what already works. Filter your search by funding stage so you apply where your skill set actually maps to what they need.
Build a two-page work sample
Many hiring teams skip a formal portfolio requirement but still want proof of product thinking. A concise document showing one technical decision you made, the alternatives you considered, and the outcome gives interviewers something concrete to react to.
Prepare for the technical plus product split
Founding product engineer interviews almost always combine a coding round with a product design or system scoping session. Practice articulating why you made architectural choices, not just how you implemented them, since that hybrid judgment is exactly what the role demands.
Negotiate scope alongside compensation
Early-stage companies often have more flexibility on role definition than on cash. When you get an offer, ask which product areas you would own in the first six months. Clarifying scope upfront prevents the common situation where a founding engineer ends up doing pure infrastructure work they did not sign up for.
Founding Product Engineer Jobs: Frequently Asked Questions
Which companies are hiring the most founding product engineers?
The companies hiring the most founding product engineers right now include CLERA, deCircle, and Alpaca Health, with the largest share of openings in California, New York, and Washington, based on current listings on Migrate Mate as of November 2026. Hiring activity shifts frequently as early-stage companies raise new rounds, so checking current listings gives you the most accurate picture.
How many founding product engineer jobs are remote?
About 38% of founding product engineer openings are fully remote or hybrid as of November 2026, reflecting the distributed nature of many early-stage startups. Full-stack and infrastructure-focused roles tend to have the highest share of remote availability, while roles that require close daily collaboration with a founding team are more likely to be on-site or hybrid.
How do you become a founding product engineer?
Start by building a record of shipping complete features or products independently, since founding roles require you to own outcomes rather than contribute to a larger team's work. Develop comfort with the full stack, basic infrastructure, and product thinking. Working at a small startup before targeting a founding role gives you the operational context that hiring teams are specifically looking for.
Can you get a founding product engineer job with little experience?
It is possible if you can demonstrate that you have shipped something real on your own. Side projects, open-source contributions, or freelance work where you made architectural decisions and saw them through to production matter more than years of experience at a large company. Apply to roles at the earliest-stage companies, where the bar shifts toward potential and ownership mindset rather than a specific year count.
What does the founding product engineer interview process look like?
Most founding product engineer interviews include an initial conversation with a founder or lead engineer, a technical screen covering code quality and system design, and a product thinking session where you work through how you would approach building a core feature. Many processes end with a short paid or unpaid work sample. The whole process is usually faster and less structured than interviews at larger companies.
Where can I find and apply to founding product engineer jobs?
You can find and apply to founding product engineer jobs on Migrate Mate, which lists current openings from across the United States. Search for roles that match your stack and stage preference, then apply directly to each listing that fits.
