You love challenges
Building a managed platform is hard. Data modeling, GC optimization, caching strategies, memory management, load balancing, and scheduling genuinely excite you.

You’re a team player
You are opinionated yet thrive in a collaborative environment; you bring your ideas and an open mind, not your ego, to brainstorming sessions. You enjoy providing technical advice to others.

You’re a good communicator
Whether it is in email, chat, voice, tickets, code comments, commit messages, or in person, you communicate well with other people.
