• Keeping our community safe and supported:
  • Moderation and support tools, and user-facing features that resolve issues faster.
  • Security features such as malware detection, authentication (2FA, login, account recovery), API protection, rate limiting and user data protection.
  • Compliance and legal requirements, including child safety legislation, GDPR and cookie compliance.
• Helping our platform and business grow:
  • Improving how users experience value and become paying supporters, through upsells, pricing localisation and onboarding.
  • Building the foundations for community growth, such as creator partnerships and new audience acquisition.
  • Admin tooling, dashboards, marketing integrations and data tools that teams across the company can rely on.
• Core platform and ecosystem:
  • Helping millions of gamers discover, download and manage mods, and empowering creators to publish and manage their work with confidence.
  • Building high-traffic APIs serving millions of requests per hour, for both web and desktop applications.
  • Tackling complex challenges around dependencies, versioning and compatibility.
  • Improving performance, scalability and reliability, and addressing technical debt so we're ready for the next decade of growth in gaming.

• Contribute to product discovery by prototyping, validating feasibility and surfacing trade-offs early.
• Improve observability, reliability and operational standards, and drive best practice in performance, database design and security.
• Write clean, well-tested code, uphold high standards across CI/CD and documentation, and mentor other engineers.

Requirements

• Experience in backend development with a focus on scalability and security.
• Proficiency in designing and maintaining APIs.
• Strong collaboration skills with cross-functional teams.
