Job Specifications

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 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.

Partnering with product designers and product managers to build and improve workflows and user experience for various personas like Candidate, Recruiter, Interviewer, and Hiring Manager
Building uniform software front-end components that are pluggable and can be used across the organizations for various offerings.
Understanding key web performance metrics for the product and strive to improve it regularly
Actively participate in setting up good standards and conventions for front-end engineering and also review code for quality. We believe good code is like good karma; it goes a long way.
Collaborating with the engineers across the team; for organization-wide initiatives, with the mission to improve software quality and user experience regularly
Mentoring budding Engineers and Interns

You have the ability to anticipate threats (e.g., misuse of LLMs or cheating tools) before they become widespread.
You have the ability to design preventive solutions rather than reacting only after an incident.
