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](https://www.playsupremacy.com/en/games/warhammer40k), 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

• 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 PROFILE

• You have an engineering mindset and a passion for the craft.
• 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.
• 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
• You are at least familiar with PHP.
• You have a proactive attitude towards learning new technologies and improving existing skills, including leaving the comfort zone of your programming language.
• You have experience developing and maintaining multi-server, high-load backend services and APIs.
• Familiarity with SQL and NoSQL databases, including MySQL, PostgreSQL, MongoDB, or similar.
• You are enthusiastic about games and ideally strategy games.

##### Nice-to have skills to impress us
