DevOps Engineer II

HackerRank helps thousands of companies like OpenAI, NVIDIA, Amazon hire developers based on their skills vs pedigree, and also nurtures a community of millions of developers to upskill themselves to become the next-gen developers. The people at HackerRank care deeply about their work and have an extremely intense work ethic. In many companies, speed & quality is a tradeoff. At HackerRank, it’s not -- we expect you to ship in about half the time that most competent people think it’s possible while maintaining a standard of quality you’d proudly sign your name on. The only way to make this happen is if you truly love your craft and are deeply committed to growth.
