As a Sr. Full-Stack Engineer, you'll join a small, fully remote team working on backend systems for a multiplayer, action RPG title. Responsibilities include designing and implementing scalable online services, collaborating on back-end services, building web services interacting with blockchain and game servers, optimizing and debugging complex systems, and building maintainable code. You'll partner with a front-end engineer but some front-end familiarity is needed. The tech stack includes Node.js, TypeScript, MongoDB, React, PostgreSQL, and C++.
