Founding Product Engineer

• Mon-Fri in NYC HQ (we learn best shoulder-to-shoulder)
• Hours & WFH flexibility as needed.

Manual data entry is the worst part of most white-collar jobs. Nobody has it worse than lawyers, who track their time in 6 minute increments. Ajax automates data entry drudgery away, starting with lawyers, and starting with timekeeping.

Stage: We’ve hit product-market fit and are, doubling ARR every ~2 months.

Founding Team:

• Jack Weinberger - Founder, GTM (Yale, PE, Chief of Staff at Humming Homes)
• Alex Weinberger - Founder, Eng. & Product (Amazon, Founding Eng. at dub)
• Roger Jin - Founding ML Engineer (Harvard, Carnegie Mellon, nference)

• Our inference engine generates high quality time entries for attorneys; you’ll help extend our pipeline to make it work for more users and perfect it to keep them coming back.
• Our team cares deeply about our mission, works autonomously, and supports each other. Engineers talk to customers, explore problems, prototype features, and maintain their code.
• We all genuinely like each other, have each other’s backs, and celebrate the wins as a team.

• Talk with a firm’s managing partner: our customers help write our roadmap!
• Pick a problem and prototype a fix: We ship fast and iterate fast - the best way to see if a user wants something is to build it
• Validate your solution: reach out to a few customers and show them what you’ve built
• Productionize the prototype: we can’t ship what we can’t maintain
• Rinse and repeat: did we build the right thing? Did we build it right? The answer isn’t always yes, but we learn from our mistakes and take the lessons to the next battle

• You have full stack experience - Python (or similar) and React (or similar) are a plus
• You’ve built projects from inception through delivery - you might have led a feature, founded a company, or built a side project that took off
• You like working with new tech - this company wasn’t possible pre-transformer
• You have strong communication skills - we talk to customers and coworkers all day

• 30m phone screen with Jack
• 45m technical screen with Alex (no live coding)
• Paid day of work: meet the team and work on a small project in person
• Decision!

• $130-180k base + meaningful equity
• Benefits: health, dental, vision

If pushing code into a complex AI pipeline, building with a growing, hungry team, and making people’s lives better sounds fun, we’d love to talk.
