Senior Fullstack Engineer - Node.js/TypeScript

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.

As a Senior Fullstack/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 are interfacing with other internal and external services. In the beginning, you will work on extracting loosely coupled microservices out of our monolithic PHP application. 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.

In this role, you will collaborate closely with game designers, producers, and other stakeholders to create innovative services that enhance the player experience and enable internal stakeholders to work more efficiently.

Please submit your resume outlining your relevant experience and why you are interested in joining Twin Harbour Interactive. We look forward to hearing form you!
