Contract Backend Software Engineer
RMG is partnering with a growing technology business to secure a Contract Backend Software Engineer for a full-time, hybrid engagement based in London. In this role, your primary objective will be to take immediate technical ownership of core backend services—architecting resilient systems, untangling intricate data flows, and elevating the platform's overall scalability and reliability. If you are an autonomous contractor who excels at transforming architectural requirements into clean, performant services, this project offers an exceptional opportunity to make an immediate, tangible impact.
Key Responsibilities
- Architect, build, and maintain scalable backend services and microservices designed for long-term reliability and performance.

- Collaborate closely with cross-functional technical teams, including frontend engineers and product stakeholders, to steer architectural decisions.
- Enhance continuous deployment and testing frameworks to safeguard code quality, system observability, and engineering standards.
