Build like a founder. Ship like Spartan.

Our clients are startups in a race: an MVP in 30 days, one demo away from a funding round. We’re looking for a Backend Engineer to run that race with us.

We don’t act like vendors. We embed. Our teams sit inside startups backed by YC, Pear VC, BlingCap, a16z, and Techstars, working beside founders and engineers from Stanford, MIT, Yale, Google, Amazon, and Uber. Together we ship those MVPs and scale the systems behind them to millions of users and billions of requests.

This isn’t outsourcing where you sit three layers away from the client. You’ll be in the founder’s Slack. Your code runs their production. When their demo lands a funding round, that’s your work on the screen.

70% of our portfolio is LLM-powered. Cursor, Claude, and Codex are default tools here, not experiments. You’ll use AI every day, and you’ll be expected to use it well.

Who Thrives At Spartan

Not every workplace fits everyone, so here’s an honest picture of the teammate we’re looking for.

You’ll Thrive Here If

You do whatever it takes to win. Multiple hats,



unglamorous work included.
You take on the hardest part of the project and see it through to shipped.
You pick up a new stack in days, not months, because the project needs it.
You’d rather own a problem than a ticket.

Some weeks will stretch you. That’s the job. But you’ll never carry it alone. A critical client release or a tricky production issue? Someone always has your back. We push each other hard because we care how far each of us can go. We win together. We lose together. Nobody gets left behind.

One last thing. We’re not filling seats. We’re looking for teammates for the battles ahead. If you read all this and something in you said yes, trust that feeling and apply. We respect people who back themselves. Every Spartan here started with that same yes.

What You’ll Do

Design and build scalable microservices that power high-growth startups.
Build LLM features end to end: RAG pipelines
