AI has accelerated how products are built for customers, and our Seed to Series B startups need hands-on builders who thrive in that environment, working closely with users to turn ideas into real, impactful solutions. This role is ideal for future founders, offering exposure to a wide range of challenges and direct experience solving real customer problems. We’re seeing strong demand in startups across healthcare, cybersecurity, finance, and other fast-growing sectors.

This role is a great fit if you:

• Love seeing your code solve real-world problems
• Prefer shipping something valuable today over perfecting it next month
• Can explain complex tech to someone who thinks Python is just a snake
• Are comfortable being wrong — and learning fast
• Have built and deployed production software that real people use
• Aspire to be a founder in the future

What we're looking for:

• 1+ years of professional experience
• Strong engineering background, ideally in Computer Science, Mathematics, Software Engineering, Physics, or Data Science
• Experience prototyping in TypeScript, JavaScript, or Python

Location: San Francisco
