The Role

We are looking for a Senior Go Engineer to join our team and help build high-quality, scalable backend services and APIs. This role is perfect for someone with hands-on experience in Go who is ready to take ownership of features end to end, contribute to technical decisions and work on impactful projects. If you're passionate about writing clean, performant code and working with modern cloud-native technologies like AWS, Docker and Kubernetes within a strong engineering team, we'd love to hear from you!

What your day will look like:

• Design and develop high-performing backend services and APIs using Go, ensuring reliability, scalability and consistency across distributed systems
• Build and maintain RESTful APIs and gRPC services with clear contracts, versioning discipline and robust error handling
• Integrate AWS services such as DynamoDB, Lambda, S3 and Cognito to deliver scalable and secure backend solutions
• Contribute to architectural discussions and technical decision-making across the backend stack, helping shape patterns that support long-term maintainability
• Build, containerise and deploy services Docker and Kubernetes, working with CI/CD pipelines to keep releases fast, safe and repeatable
• Write and maintain automated tests, including unit, integration and end-to-end tests, to ensure code quality, reliability and confidence in every release
• Monitor and optimise service performance, identifying and resolving bottlenecks in latency, throughput, concurrency and resource usage
• Take part in code reviews, giving and receiving constructive feedback, and support less experienced engineers in developing their Go skills
• Collaborate closely with product managers, designers and web and mobile engineers to translate requirements into production-ready features
• Stay current with the Go ecosystem and cloud-native tooling, proactively evaluating new libraries, tools and AWS service updates to continuously improve the development stack
