HackerRank is hiring a Customer Experience Engineer (L1) in Bengaluru. In this technical support role you will investigate real customer problems across the HackerRank platform, its APIs, integrations, authentication, configuration and data, and own standard customer issues from first investigation through to resolution. Day to day you will debug issues using logs, browser developer tools and SQL, write clear customer-facing replies on tickets and calls, raise structured escalation reports for confirmed product bugs, and turn what you learn into documentation, runbooks and small automation improvements. Safe use of AI tools to speed up investigations is part of the job. The role is open to freshers and candidates with up to 3 years of experience (B.E./B.Tech graduates, including the 2025 and 2026 batches). Familiarity with REST APIs and HTTP status codes, log reading and SQL is expected. Note: this is a rotational role covering a 24x7 support window with weekly rotating shifts, including mornings, evenings and weekends, and requires working from the Bengaluru office at least three days a week.
