Job Description:

At The Multiplayer Group (MPG), we create world-class multiplayer experiences through Co-Dev and Full-Dev partnerships. Our people-first culture supports a diverse, global team in a welcoming and flexible work environment. With teams spread worldwide, we prioritise connection—both online and in person. Giving back is central to who we are, with a focus on local communities, education, and sustainability. We are looking for a deeply talented Senior Backend Engineer. You’ll be working in a team of backend engineers across MPG. We deliver, deploy and help integrate backend services alongside external co-dev clients as part of industry leading game projects, and collaborate to define solutions and implement features on time and to a high standard. We’re also developing an internal tool used across MPG, as well as growing our pool of AWS Certified engineers - both of which you will be involved with when you join us.

Job Responsibility:

Work with the team lead and stakeholders to estimate and prioritise work
Work alongside peers to iterate on solutions that fit requirements
Keep the project lead and producer apprised of revised estimates and delivery times
Champion and maintain high standards and process: tests, CI/CD, documentation
Help and support team members in day-to-day work
Understand, maintain and expand existing code and develop new features or systems

Requirements:

Experience in game development and having worked on at least two game titles in a commercial setting developing server backends for AAA games, free-to-play (mobile) games, casino apps or similar
Experience releasing at least two backend services with a large number of concurrent users
Production experience with at least one of Java, Golang, C#, C++, Kotlin
experience with Python, Node.js and React is desirable

Nice to have:

Strong database experience with both SQL and NoSQL

Experience with high-scale distributed applications with a concurrent user base ranging in the hundreds of thousands, with high uptime, and performant services
An understanding of how to use LLMs to process and query structured and unstructured data

What we offer:

Flexible working: Remote-friendly long before it was the norm, with core hours that support both great work and real life
Support & wellbeing: Mental health first-aiders, therapy and coaching via Myndup, plus private medical insurance to help you stay healthy and supported
