Customer Experience Engineer, L2

HackerRank helps companies like NVIDIA, Amazon, and Microsoft hire and upskill the next generation of developers based on skills, not pedigree. Our platform is trusted by over 2,500 of the world’s most innovative companies to build strong engineering teams ready for what’s next. Software has entered an era where humans and AI build side by side. As this shift accelerates, the definition of strong technical talent is changing. We give companies better ways to identify and invest in next-generation skills. People at HackerRank care deeply about the impact of their work and sweat the small details so our customers can be wildly successful with products they genuinely love to use. We move with urgency and believe great outcomes come from high standards. About the role Customer Experience Engineering is where customers, product, and engineering meet. As a CXE 1, you’ll investigate real technical problems across our platform, APIs, integrations, data, and customer workflows. You’ll learn to trace issues to root cause, communicate clearly with customers and internal teams, and build the judgment to own increasingly complex work independently. This is not a traditional support role built around scripts and handoffs. You’ll work in one shared CXE queue, use AI as part of your everyday engineering toolkit, and contribute to the knowledge, automation, and product improvements that prevent repeat problems. CXE 1 is designed as a transition into CXE 2 as your depth, independence, and customer readiness become consistently visible. What you will do Own standard and moderately complex customer issues from first investigation through resolution and closure. Debug web application, API, integration, authentication, configuration, and data issues using logs, developer tools, SQL, and established investigation patterns. Communicate clearly and empathetically across tickets, calls, incidents, and internal channels; ask precise questions, set expectations, and close every loop. Work with

About the role Hiring is one of the most consequential decisions a company makes. 3,000+ enterprises rely on HackerRank to get it right. We are now reinventing how that works for the agentic era. The ML systems that power this platform are not auxiliary features. They are the product. Open Problems The agentic era is reshaping every layer of the hiring stack. These are some of the core problems you'll be working across, none of them fully solved. Chakra: Building an autonomous AI interviewer that conducts, adapts to, and evaluates technical interviews end to end. Integrity: Detecting fraud and suspicious behavior across multiple signal types. The ways candidates game assessments change frequently, and the models need to keep up. Evaluation: Measuring technical skill in a world where AI writes the code. The old proxies no longer hold and the new ones have not been defined yet. Your focus will shift across these depending on where the highest-leverage work is at any given time. What you will do Design and ship production ML systems across Chakra, integrity, and evaluation domains. Own the full ML lifecycle: problem framing, data strategy, experimentation, deployment, and iteration. Build evaluation infrastructure and bench

We move with urgency and believe great outcomes come from high standards. About the role HackerRank's data platform is at an inflection point. We've completed a multi-year modernisation - migrating from Redshift to StarRocks + Apache Hudi - and cut export latencies from 25 seconds to under 5 seconds. The infrastructure groundwork is done. Now we're building the AI-native data layer that will power revenue-generating features like natural language querying for HackerRank for Work customers. As Lead Data Engineer, you'll be a senior individual contributor at the heart of the data organisation - owning complex platform decisions, collaborating cross-functionally with AI, product, and go-to-market teams, and shipping data-driven features that directly drive revenue. This is a greenfield opportunity to shape the next phase of data at HackerRank. What you will do Own and evolve the data platform - StarRocks (OLAP), Apache Hudi (Data Lake), Trino, Spark, and Apache Ranger - ensuring performance, reliability, and security at scale. Build the next-gen AI-optimised data layer: clean, structured datasets that power natural language querying and AI add-on features for HackerRank for Work customers. Own in-product data features - exports, insights dashboards, interview analytics, and the self-s
