Join us as Senior Node.js Developer on Warhammer 40,000: Supremacy!
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!
Innovation is part of our DNA. We actively integrate Artificial Intelligence to reduce repetitive tasks and create space for what really matters: strategic thinking and human connection. We don't just use AI - we look for people who can shape the way we work with it.
We are seeking an experienced Senior Node.js Developer (all genders) to join our team working on a successful Free-to Play (F2P) mobile strategy game. You will be part of our interdisciplinary team developing, building and running Warhammer 40,000: Supremacy , an ambitious online grand strategy game set in the iconic Warhammer 40k universe. You can expect a professional and international working environment covering a wide scope of technologies and a deep focus on delivering a visually pleasing and technically excellent player experience.
In this role you will be working on both: a legacy PHP backend and new services in Node.js meant as a replacement for the former. The services will be running on a distributed architecture in the Google Cloud. Your work will align with best practices in stability, performance, scalability, security, and maintainability. These services are meta-services handling things such as player-data or live-ops and monetization related information.
Our frontend is a Unity client and it is also connecting to a dedicated Gameserver written in Java.
YOUR MISSION
Be part of an experienced and passionate engineering team building a flagship title in the Warhammer 40,000 universe.
Take Ownership for maintaining our legacy central meta-data PHP-service that is heavily used by other stakeholders like game design and monetization.
Take Ownership of modernizing our meta-data service adopting new Node.js services created by our Web-API team and helping them form this completely new stack.
Design, develop, test, deploy, maintain, and improve our software with high-quality, maintainable code.
Work closely with game designers and product leads to implement new features with an interest in learning the complementary full-stack technologies.
Work closely with an internal team focusing purely on replacing our legacy PHP-service and adopting their work for the Warhammer 40.000 team.
Create new Node.js services in this eco-system for specialized functionality relevant for the Warhammer 40.000: Supremacy game.
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.
YOUR BACKSTORY
You have an engineering mindset and a passion for the craft.
7+ years of proven experience in Node.js/Typescript development,…
