We're scaling platforms that thousands of students and teams depend on:
You'll own one of these platforms and spend most of your time building the complex parts of the codebase alongside a small team (3-5 strong engineers, no juniors). Your architecture decisions determine whether other teams can rapidly build new apps, integrate cleanly, and add value to students. Get this right and you enable massive leverage. The wrong decisions create integration nightmares and kill velocity across multiple teams.
You build and operate what you design. You establish quality bars and patterns for your platform. We're spec-driven: you design before you implement, always plan before you build. High autonomy, no committees, no review boards. Small tight-knit team, where you're accountable for what you ship.
Crossover's skill assessment process combines innovative AI power with decades of human research, to take the guesswork, human bias, and pointless filters out of recruiting high-performing teams.






It’s super hard to qualify—extreme quality standards ensure every single team member is at the top of their game.
Over 50% of new hires double or triple their previous pay. Why? Because that’s what the best person in the world is worth.
We don’t care where you went to school, what color your hair is, or whether we can pronounce your name. Just prove you’ve got the skills.
