Senior Backend Engineer - Node.js/TypeScript

Join to apply for the Senior Backend Engineer - Node.js/TypeScript role at Twin Harbour Interactive.

At Twin Harbour Interactive we strive to develop high-quality strategy games and make them accessible for all players around the world. In our eyes, game development is a promise for fun and entertainment – that’s what we live and aim for!

As a Senior Backend Engineer – Node.js/TypeScript, you will be responsible for designing, building, and enhancing features for our game platform, focusing on applications used by our game teams as a service that interfaces with other internal and external services. In the beginning, you will work on extracting loosely coupled microservices from our monolithic PHP application. The services will run on a distributed architecture in the Google Cloud. Your work will align with best practices in stability, performance, scalability, security, and maintainability.

Your Mission

• You will lead and mainly work on extracting loosely coupled microservices written in Node.js/TypeScript out of our PHP monolith. However, you need to be comfortable with working in other languages like PHP as well.
• Take ownership for maintaining and extending some of the central shared services that are used by game teams and other stakeholders like game design and monetization.
• Design, develop, test, deploy, maintain, and improve our software with high-quality, maintainable code.
• 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 capacities.
• Work closely with game designers and product leads to implement new features with an interest in learning the complementary full-stack technologies.
• 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.

Your Profile

• 7+ years of 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.
• Be familiar with or eager to learn other languages like PHP or Java.
• Proactive attitude toward learning new technologies and improving existing skills, including stepping out of your comfort zone.
• 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.
• You are enthusiastic about games and ideally strategy games.
• Experience with cloud platforms (GCP preferred), networking, and debugging distributed systems is a plus.
• Hands‑on experience with agile methodologies such as Scrum or Kanban.
