Help us build the platform behind the games.

MYNT is our new supplier platform: the technology that connects games, operators and the services around them. We’re looking for a Senior Backend Engineer who enjoys solving real engineering problems in distributed, production-critical systems.You’ll join one of the squads building and evolving MYNT, working hands-on in .NET across APIs, services and data. We want someone who can get underneath a problem, ask the right questions, make pragmatic technical decisions and own a solution through to production. You’ll work closely with the Product Owner, Tech Lead and other engineers, with room to influence both what we build and how we build it.

Design, build and evolve the backend capabilities that power MYNT, taking work from technical design through implementation and delivery.

Work across services, APIs, data and integrations, making practical technical choices that keep the platform reliable and straightforward to evolve.

Contribute to solution design and implementation across the squad’s areas of responsibility, considering the wider platform and downstream impact of changes.

Take part in code reviews and technical discussions, helping maintain a consistent and sustainable engineering approach across the squad.

Turn product needs into well-considered technical solutions, working through ambiguity and making sensible trade-offs where needed.

Take responsibility for the behaviour of delivered solutions in production and help ensure issues are followed through to a satisfactory resolution.

Contribute to the day-to-day health of the platform by investigating incidents, recurring issues and areas where reliability or operability can be improved.

Support the squad’s delivery and operational practices, including releases, deployment processes, observability and production diagnostics.

Look for opportunities to improve the existing platform, reduce technical debt and simplify or automate recurring work.

Work as an active member of the squad, collaborating with Product, the Tech Lead and other engineers from idea through to delivery.

Work constructively with other squads and disciplines when changes or issues cross team and service boundaries.

Contribute to the wider engineering culture by sharing context and knowledge, giving useful feedback and helping teammates succeed.

Strong professional experience building backend systems using object-oriented programming languages (such as Java), with a preference for C# and .NET, including modern .NET/.NET Core.

Hands-on experience with Entity Framework / EF Core and relational database design.

Experience designing and evolving APIs and services in a distributed or service-based architecture.

Solid understanding of software design principles, patterns and clean architecture, with the judgement to apply them pragmatically.

Experience with CI/CD and supporting software in production.

A structured problem-solving mindset: you investigate root causes, gather the information you need and design the right solution.

A strong sense of ownership for quality and production outcomes.

Ability to prioritise and make progress in a fast-moving environment.

Comfortable working with both technical and non-technical stakeholders, with clear, pragmatic communication.

Experience with containerised and cloud-native environments such as Docker, Kubernetes and Helm.

Familiarity with API gateways, messaging systems, gRPC, event-driven or asynchronous architectures.

Experience with performance tuning, query optimisation and database scalability.

Experience with high-availability or high-throughput transactional systems.

Exposure to modern frontend applications such as Angular.
