Founding Product Engineer

  2025-10-08     Martin (YC S23)     San Francisco,CA  
Description:

We are on a mission to build real-life JARVIS — a personal AI that can do everything a human assistant can, given natural language instructions. If we succeed, Martin will be the revolutionary consumer product the world has been waiting for since the iPhone.

We launched 6 months ago, and Martin's capabilities are already light years ahead of legacy assistants like Siri and Alexa. Martin has already executed hundreds of thousands of tasks for over 30,000 users ranging from drafting emails, to scheduling meetings, to making phone calls.

Our company is profitable and funded by top seed investors, including Y-Combinator and Pioneer Fund, and our user base is growing extremely fast.

Come join our founding team in San Francisco as one of our first hires. You'll have a large impact on the direction of our company and our product, which will be reflected in significant equity compensation. We are building in one of the fastest moving industries ever, and you will have endless opportunities to learn and grow.

If you're passionate about tackling unsolved technical challenges and eager to shape the future of consumer technology, we'd love to hear from you!

Founding Product Engineer

We are looking for a founding product engineer who is an expert in design and UI/UX to lead development of our web dashboard and/or mobile app.

Users interact with our product heavily via text, voice, and email, but our web and iOS app are the critical places where they set up, reconfigure, and monitor their AI assistant. It is also where they can directly edit tasks, to-dos, reminders, and emails that Martin has created for them.

Our ideal candidate is a fast-moving full stack developer with extensive experience in UI/UX and product.

Requirements:

  • 3+ years of experience building full stack web apps from scratch (Python FastAPI and NextJS, or something similar)
  • Expert in UI/UX and design - wow us with something you've built!
  • SF-based or able to relocate to SF

Bonus:

  • Proficient in Mobile Development (React Native for Android, and SwiftUI for iOS)
  • Experience working on a growth team or being a founder

Key Responsibilities

  • Design and develop core elements of our web dashboard (our main consumer facing user interface), including our chat, integrations, and workflows interfaces
  • Collaborate with AI engineers to build a 10 star user experience for Martin's task execution flow on web
  • Optimize our onboarding flow to be as magical as this scene in Her (2013)
  • (Bonus) Lead development of core elements of our mobile app, including our chat, voice mode, and integrations interfaces
