HackerRank Careers•Santa Clara, CA

About The Position

HackerRank helps thousands of companies like OpenAI, NVIDIA, and Amazon hire developers based on their skills vs. pedigree, and also nurtures a community of millions of developers to upskill themselves to become 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 is 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. About the role As a SDET, you will play a critical role in shaping and executing our automation-first quality strategy across web, API, and AI-driven systems. You’ll work closely with Engineering and Product teams to ensure that quality is designed into every feature, enforced through strong automation, and protected by strict release gates. This is a hands-on, technically deep role with real ownership and impact.
