Senior Frontend Engineer

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.

The Integrity team focuses on ensuring that customers can rely on the results of HackerRank assessments without having to worry about any integrity issues. For online assessments, integrity of the assessment session is generally a major concern for customers, especially now, with easy availability of LLMs and specific tools built on top of it that focus on getting an advantage during online assessments. This team builds generic platform solutions that can be integrated into any HackerRank products.

Your work will directly impact the lives of millions of developers as you build the platform for them to showcase their skills and get hired. You will be responsible for building our core integrity solutions that are used across all of our products.

As a Senior Frontend Engineer, you will work on building a platform to provide customers trustable integrity solutions across all of the HackerRank products,  while also ensuring a world-class developer experience. These solutions also need to be built so they can handle a scale of over 100K concurrent users.
