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.

• 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

• 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

• Understand, maintain and expand existing code and develop new features or systems
