Software Engineer (AI) at CellStrat
📝 Note for Applicants
When filling out the application question “What interests you about working for this company?” — skip the generic stuff like “I’m passionate about AI” or “I’m a fast learner.” We’re looking for crackhead nerds/engineers who actually build things. Use this space to show us why we should even consider you:
Proof of code you’ve written or systems you’ve built end-to-end
Side projects, repos, or hacks you’re proud of
The toughest technical problem you solved or a rabbit hole you went way too deep into
If you’re the type who tinkers, obsesses, and ships — this is where you prove it.
