Job description

What are we building? Hard Rock Digital is a fiercely focused team working to become the best online sportsbook, casino, and social gaming company in the world. We're building a deeply curious team with a passion for learning, operating, and building new products and technologies for millions of consumers. We're customer-obsessed — we care about each customer interaction, experience, behavior, and insight, and strive to ensure we're always acting authentically. Rooted in the kindred spirits of Hard Rock and the Seminole Tribe of Florida, Hard Rock Digital taps a brand known the world over as the leader in gaming, entertainment, and hospitality. We're taking that foundation of success and bringing it to the digital space - ready to join us? What’s the position? We are looking for a Senior Java Developer to join our Performance Engineering team and take ownership of expanding our load testing capabilities. This role is both hands-on and hands-off-keyboard: you will be the primary developer standing up Gatling as a new addition to our load testing toolbox (which currently includes Locust and k6), while also serving as a technical mentor for the team, helping developers at every level, including senior engineers new to Java, grow their skills and adopt strong development practices. This is a high-visibility role for someone who enjoys building tooling, solving performance problems, and multiplying their impact by levelling up the people around them. Key Responsibilities Load Testing & Tooling • Own the Gatling rollout: Design, build, and productionize a Gatling-based load testing framework from the ground up, integrating it into our existing performance engineering toolbox alongside Locust and k6. • Design and execute load tests: Build realistic load, stress, soak, and scalability test scenarios that reflect real-world traffic patterns and business-critical workflows. • Analyze and report on performance: Interpret test results, identify bottlenecks (application, database, infrastructure), and work with engineering teams to resolve them. • Build reusable frameworks: Develop maintainable, well-documented Gatling simulations and supporting utilities/libraries that other engineers can extend. • Integrate with CI/CD: Automate load test execution and reporting as part of the deployment pipeline. Mentorship & Engineering Practices • Mentor engineers: Provide structured and informal mentorship to mid-level, junior, and senior engineers, including senior engineers from other language backgrounds, on Java fundamentals, idiomatic patterns, framework usage, and best practices. • Champion best practices: Establish and evangelize coding standards, testing strategy, and performance-engineering best practices across teams. • Collaborate cross-functionally: Partner with development, QA, DevOps/SRE, and architecture teams to embed performance testing earlier in the development lifecycle. Success Measures • Gatling is fully integrated into the performance engineering toolbox with documented frameworks/patterns other engineers can use independently. • Mid, junior, and non-Java-background senior engineers show measurable growth in Java proficiency and testing practices as a result of your mentorship. • Load testing is a standard, automated part of the release process rather than a manual afterthought.
