Senior Backend Engineer - The Multiplayer Group (MPG) in London

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 will 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 are 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.

Experience:

• 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.
• Experience with cloud platforms: Amazon Web Services, Google Cloud and Microsoft Azure; having an AWS Certification (Associate or above) would be advantageous.
• Experience with infrastructure as code tools, e.g. Terraform.
• Ability to independently create supporting documentation, designs, comments, etc.
• Ability to discuss technical and production matters.
• Excellent time management and ability to work independently.
• Experience building distributed applications.
• Attention to detail with ability to comprehend and follow direction.
• Strong communicator with the ability to verbalise conceptual thoughts and the willingness to accept constructive critique.
• Experience with Git or Perforce, or other source control software.
• Ability to adapt to new tools, languages, and concepts as required by the project.
• Knowledge of Microservices and Service Oriented Architectures (SOA), especially Kubernetes and Docker.
• Experience building a CI/CD pipeline to validate and test code.
• Awareness of security/cheating implications of technology choices.

Beneficial:

• Strong database experience with both SQL and NoSQL.
• Understanding of how a backend service integrates with the game - experience with Unreal or Unity would be useful but not required.
• 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.

Responsibilities:

• Individual contribution: construct systems, write code, deployments, etc.
• 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.

Please don’t forget to include your CV, a cover letter, and links to your GitHub, website or portfolio.

Our Benefits:

• Flexible working: Remote‐friendly long before it was the norm, with core hours that support both great work and real life.
