• Define SLOs, add metrics/tracing/logging, participate in on-call/incident reviews, and continuously harden reliability & performance for live operations.
• Leverage AI tools and technologies to enhance development efficiency, code quality, and problem-solving capabilities.
• Work closely with game designers and product leads to implement new features.
• Communicate and collaborate within a cross-functional team and with other teams to ensure a smooth daily workflow.
• Actively bring in new ideas and participate in technical decisions influencing the architecture of our services and platform.
• Drive initiatives to enhance the stability, performance, and scalability of our platform and live games.
• Contribute high-quality, maintainable TypeScript code using a wide range of technologies such as Next.js, Nest.js, Jest, Mocha, Turbopack, GitHub, Docker, MySQL, Pub/Sub, and Redis.
• Mentor engineers via design reviews, pairing, and by setting coding standards and contribute to engineering hiring.

Requirements

• Proven experience in Node.js/TypeScript development, demonstrating strong coding and debugging skills.
• Proficiency in popular Node.js/TypeScript frameworks such as Next.js, Nest.js, Express.js, and Jest.
• Deep experience with distributed systems: queues/pub-sub, idempotency, data modeling across service boundaries, and eventual consistency.
• Excellent verbal and written communication skills, with the ability to work effectively in a cross-functional team environment.
• Demonstrated ability to effectively integrate AI tools into development workflows for code generation, debugging, and technical research.
• Familiarity with or eagerness to learn other languages like PHP or Java.
• Proactive attitude towards learning new technologies and improving existing skills.
• Experience developing and maintaining multi-server, high-load backend services and APIs.
• Familiarity with SQL and NoSQL databases, including MySQL, PostgreSQL, MongoDB, or similar.
• Strong automated quality mindset using unit testing, integration testing, and other test automation frameworks.
• Enthusiastic about games and ideally strategy games.

• Hands-on experience with agile methodologies such as Scrum or Kanban.
