Principal Software Engineer (Java) Gaming Tech

Job description

Homa is a global mobile game developer and publisher creating games people love.

We partner with studios and internally develop games, having launched over 80 titles, reached over 2 billion downloads, and seen our game All in Hole break into the global top-50 grossing charts.

These are milestones, not the finish line. 

With deep expertise in product and technology, we built Homa Lab, our proprietary platform that gives developers the market intelligence, data tools, and game tech, with AI built-in, to find product–market fit fast and scale mass-market games into lasting experiences players enjoy for years.

This is our flywheel: Homa Lab helps studios spot the right ideas early, turn them into games quickly, and reach millions of players.

Every launch brings back data and insights that fuel the next hit, making each turn of the loop faster, smarter, and more likely to win.

AI supercharges this process, running through everything we do, from everyday tasks to our guiding principles.

What powers the loop is talent density.

220+ people from 30+ nationalities, bringing expertise from the world’s best studios and companies.

We uphold ambition, curiosity, humility, and focus, and deliver with speed, excellence, and candor.



Since the start, we’ve raised $165M from Headline, Northzone, Eurazeo, Bpifrance, and the founders of King, Sorare, and Spotify, people who’ve built and backed the games and platforms we admire, now supporting our drive to create the next ones.

At Homa, we are building the next billion-player experiences from the ground up and shaping the future of entertainment.
