Senior Backend Engineer

📍UK Remote

Does this sound like you?
You’re a seasoned backend engineer who loves solving complex problems at scale. You think in systems, write clean and thoughtful code, and care deeply about performance and reliability. You enjoy collaborating with product managers, designers and DevOps teams to bring ideas to life, and you’re just as comfortable shaping architecture as you are reviewing a pull request. You lead by example, share your knowledge generously, and take real pride in building services that people rely on every day.

What you’ll be doing (in a nutshell):
As a Senior Go Developer in our Engineering team, you’ll play a pivotal role in shaping the future of our backend architecture. Working within a cross-functional squad, you’ll design and deliver robust, scalable microservices that power seamless experiences for millions of users. From architecture decisions to production optimisation, you’ll have real ownership and impact.

Day-to-day you can expect to:

• Design, build and maintain high-performance microservices in Go

• Own the full lifecycle of services – from initial design through to deployment, monitoring and ongoing optimisation

• Develop and implement gRPC and RESTful APIs

• Work with DynamoDB, Elasticsearch and MySQL to design efficient, scalable data solutions

• Contribute to event-driven architecture patterns and distributed systems design

• Write clean, testable code with strong unit and integration test coverage

• Collaborate closely with DevOps to deploy, monitor and improve services in production

• Troubleshoot and resolve production issues to ensure high availability and sub-second response times

• Take part in agile ceremonies including sprint planning, backlog refinement and retrospectives

• Mentor junior engineers through code reviews and pair programming

• Influence technical decisions around APIs, database schemas and infrastructure with a long-term mindset

To be successful, you'll have:

• At least 3 years’ experience developing user-facing features and services in Go

• Strong experience with DynamoDB, Elasticsearch and MySQL

• Solid understanding of gRPC and RESTful API design

• Experience working with event-driven architectures and distributed systems

• Deep knowledge of Go routines and channel patterns for concurrent applications

• Confidence using Git and working in an agile, scrum-based environment

• A strong grasp of software architecture principles and emerging technologies

• Excellent written and verbal communication skills

Bonus points if you bring:

• Experience with Docker and Kubernetes

• Familiarity with CI/CD pipelines and cloud platforms such as AWS, GCP or Azure

• Exposure to observability and logging tools such as Prometheus, Grafana or CloudWatch

• An interest in AI-based code editors

• Some familiarity with front-end or mobile technologies

• Contributions to open-source projects or involvement in engineering communities
