Full Stack Product Engineer

About the role

About Wefunder

We've raised over a billion dollars for thousands of founders in all 50 states, from ostrich farms to unicorns like Substack, Replit, & Mercury.

We're a Public Benefit Corporation with a mission to keep the American dream alive. We're fighting to keep America defined by optimism, innovation, and opportunity—the best place for the ambitious to turn ideas into reality.

We believe America is full of untapped talent, and that helping more founders get off the ground leads to a better future. Our goal is to help 20,000 more founders get off the ground. We're just getting started.

We're a team of founder types: enjoy autonomy, responsibility, the opportunity to learn, and no red tape. Just make it happen.

The Role

We're looking for engineers who can help us wrangle complex systems and delight users along the way.

Over 70% of our new code is AI-generated. We're not just using AI — we're deep in the weeds figuring out how to build reliable, production-grade software with it. What does code review look like when 500 agents made a PR last night? How do you maintain quality across a codebase when everyone in the company is vibe coding? These are the questions we're answering in real time, and this role is at the center of that.

We want someone who's excited to shape that playbook — to experiment with new tools, push the boundaries of what's possible, and help define how a small team punches way above its weight with AI as a force multiplier.

As a Wefunder engineer, you'll have a tremendous amount of influence, the ability to make a huge impact, and be expected to work on a little of everything. There's no red tape. It's a small team, and we move fast.

We're very good at figuring out visa sponsorship when required.

Location & Culture

We're strong believers in an in-person culture. Our HQ is in San Francisco — we have two offices, one in the Mission and one in Seacliff with a view of the Golden Gate Bridge.

We're a small team of ~30 that hires carefully. In this new AI world, one star can outcompete 10 average people. We'd rather stay lean, move fast, and spend our time building — not navigating big-company bureaucracy.

We're tight-knit enough to spend 10 days on a train together without killing each other. Four times over the years, we've all taken the Amtrak coast to coast, stopping in 12 cities. We're a team of doers and thinkers who are insatiably curious — not just about work, but about kickboxing, mountaineering, chess, and everything in between.

What We're Looking For

Complexity wrangler

We move money, deal with securities law, and serve both founders and investors. Our systems are complex by nature. You're someone who can navigate that complexity and keep things simple where it counts.
