25madison builds and invests in businesses through studio, venture and buyout strategies. We focus on AI modernization of legacy companies.
About the role
We’re looking for a strong, product-minded engineer who can take an ambiguous problem and turn it into working software. Someone who uses AI coding tools heavily, cares about the people using what they build, and doesn’t need every next step spelled out. You’ll report directly to our CTO, and work hands-on across startups in the studio. This is a building role: you’ll help decide what we should build, own the implementation, and stay close to how it performs with customers. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- A track record of shipping. You’ve built and maintained production software that people use. You can take meaningful work from an initial conversation through deployment without requiring a detailed specification
- Strong engineering fundamentals. You’re comfortable across frontend, backend, APIs, databases, and cloud infrastructure. You can debug unfamiliar systems, make sound technical tradeoffs, and keep solutions simple
- An established AI coding workflow. You already use AI tools extensively to build, test, debug, and refactor. You know how to direct them, recognize weak output, and verify the result. You can explain the code you ship
- Product empathy and judgment. You care whether the product makes someone’s job easier. You notice confusing interactions, ask good questions, and use customer feedback to change what you’re building
- High agency and clear communication. You identify what needs to happen, propose a path, and move it forward. You surface blockers early, ask for help when needed, and take responsibility for the outcome
- Startup experience is helpful. Evidence of what you can build and how you think matters more than a particular degree, title, or number of years

- Take products from idea to production. Turn early concepts and customer problems into prototypes, ship useful first versions, and improve them as the business grows.
- Work directly with founders, designers, and customers. Understand workflows, challenge assumptions, and help determine what matters most. Sometimes the right engineering decision is to build less.
- Build across the stack. Own interfaces,...
