We’re hiring multiple Senior Go Backend Engineers (contractors) to join a large-scale public sector transformation programme delivered by a highly regarded product consultancy. This work is focused on moving critical systems away from a legacy C# ecosystem into a modern, scalable, cloud-native architecture.
You’ll be joining cross-functional teams responsible for building resilient backend services that support high-impact, user-facing products used at national scale. This is a 6-month initial contract, ideal for engineers who enjoy working on meaningful systems, solving complex migration challenges, and delivering production-grade backend services, fast.
This is a hands-on backend engineering role with a strong focus on system design, scalability, and delivery. You’ll be expected to:
- Build and scale backend services using Go within a cloud-native AWS environment
- Contribute to the migration of legacy C# systems into modern distributed architectures
- Design and develop APIs and event-driven systems
- Work closely with product, design, and other engineers in cross-functional teams
- Apply modern engineering practices including TDD, CI/CD, and Infrastructure as Code
- Write clean, maintainable, and well-tested production code
- Contribute to architectural decisions balancing performance, scalability, and delivery timelines
- Support continuous improvement through code reviews, pairing, and knowledge sharing
This role suits engineers who enjoy working on real-world systems at scale and are comfortable navigating complexity in modernisation programmes.
Technical Requirements:
- Strong, recent experience with backend development using Go (Golang) in production environments
- Designing and building scalable APIs and distributed systems
- AWS cloud services (e.g. Lambda, ECS/EKS, S3, RDS)
- SQL and data modelling (relational databases)
- Working within microservices or event-driven architectures
- CI/CD pipelines and modern delivery practices
- Infrastructure as Code (e.g. Terraform or similar)
- Test-driven development and automated testing strategies
- Observability, performance tuning, and system reliability
Nice to Have:
- Experience migrating legacy systems (e.g. C#/.NET to Go)
- Exposure to containerisation (Docker, Kubernetes)
- Experience in public sector or highly regulated environments
- Familiarity with event streaming (Kafka, SNS/SQS, etc.)
Why This Contract Stands Out:
- £400-450 per day
- Outside IR35
- Fully remote within the UK
- Long-term programme with strong likelihood of extension
- Opportunity to work on systems with real national impact
- Modern tech environment with strong engineering practices
- Product-led teams with a pragmatic delivery culture
This isn’t a greenfield fantasy, it’s a high-impact backend role focused on modernising critical systems and delivering software that genuinely matters at scale.
