Software Engineer (19B0D97)
Referment · London, England ·
Last confirmed by our partners on 23 Oct 2026.
Referment is working with a banking technology company that are looking for a back-end Software Engineer to develop the services behind its banking platform, with an emphasis on production-ready code and automated testing.
You'll work on scalable, performant microservices and stay involved as your changes move from test environments into production. The engineering approach uses continuous deployment and a shared codebase, so writing the feature is only part of the job: testing, debugging deployments and integrating changes coherently with other teams also matter.
The role also has a customer-facing dimension. You'll translate customer requirements into actionable engineering work and contribute to scoping projects and defining deliverables. It offers a mix of hands-on back-end development, cross-team collaboration and practical involvement in delivering software for banking clients.
The Role
- Design and implement microservices, considering scalability and performance as part of the development process.
- Write automated unit and integration tests alongside the application code to support reliable releases.
- Work with other engineering teams to make sure new features fit coherently into the wider platform.
- Manage and debug deployments from testing environments through to production.
- Turn customer requirements into trackable tickets and contribute to project scoping and deliverable definition.
What We're Looking For
- Experience developing software in either Python or Go; you do not need both.
- Experience making automated testing an integral part of the development cycle.
- An interest in client-facing projects, including understanding requirements and defining what will be delivered.
Useful Additional Experience
Cloud platforms such as AWS, SQL or NoSQL databases, networking and client/server or microservice architectures would be useful. Experience with orchestration tools such as Kubernetes or Mesos, or knowledge of banking and finance, is also welcome rather than essential. This could suit a back-end engineer who enjoys building and testing services, following them into production and understanding the customer problem behind the work.
