Join a stealth startup to build scalable AI/ML systems, work with founders on products, and shape engineering culture. Ideal candidates have strong software engineering fundamentals and 3+ years of experience, particularly in startups or with AI systems.
The summary above was generated by AI

We’re a stealth company bringing a 100-year-old legacy services industry into the AI age. We have a strong pipeline of customers and just raised a $10M in seed funding from Tier 1 VCs. We’re building out a cracked, high-agency founding team. Come work with us!

What makes you a great fit

  • You aspire to be a great founder yourself one day
  • A+ people want to work with you
  • You run towards complexity and hard problems
  • You have high empathy and challenge both yourself and others
  • You think for yourself, and when presented with new data, you can change your mind
  • You take pride in outcomes
  • You chase curiosity, even if it’s unconventional and aren’t afraid to do things your own way
  • You move fast, take ownership, embrace ambiguity, learn constantly, and collaborate across functions—all while having fun and making real impact

What you’ll do

  • Build end-to-end: from scrappy prototypes to production systems that actually scale
  • Work with clients to turn messy, ambiguous asks into crisp technical solutions
  • Play with the newest tools in AI/ML—experiment, break things, and push what’s possible
  • Help set the tone for engineering culture, best practices, and infrastructure from day one
  • Jam directly with the founders on product direction, technical strategy, and the first wave of hires

Good-to-haves

  • Strong fundamentals in systems design + software engineering (heads up: our interview process is tough)
  • “Dangerous enough” across the stack (backend, frontend, data, infra) and curious enough to figure out the rest on the fly
  • Clear track record of excellence and ready to choose your own adventure
  • Excited to dive into new problems, languages, and tech
  • 3+ years of engineering experience (bonus points if it’s at a startup)
  • Extra spark if you’ve touched ML, LLMs, or applied AI systems

Why join us

  • We’re changing the way 85% of the US economy works. Be part of creating a new $100B product category
  • Get in on the ground floor of a top-tier VC–backed startup with outsized ownership and impact
  • Be one of the very first hires - your fingerprints all over product, culture, and company DNA
  • Work directly with founders who have done this before on big technical and business bets
  • No red tape, no legacy code—you’re starting on a blank canvas
  • Move fast: prototype, ship, break, learn, repeat
