About the Job you are considering:

We are looking for a Backend Software Engineer with strong experience in Kotlin and/or Java, who thrives in designing and building scalable, cloud native microservices and APIs.

In this role, you will work within a Developer Experience (DevX) function, building platforms, frameworks, and tooling that enable engineering teams to develop, deploy, and operate applications efficiently and consistently.

Collaboration is central to the role you will work closely with developers, product owners, and stakeholders, contribute to architectural discussions, participate in code reviews, and help drive continuous improvement across engineering practices.

Hybrid Working

The places that you work from day to day will vary according to your role, your needs, and those of the business; it will be a blend of company offices, client sites, and your home; noting that you will be unable to work at home 100% of the time.

  • Perform hands–on backend development using Kotlin and Java, with flexibility to work across both languages where required
  • Design, develop, and maintain high-performance REST APIs and microservices using the Spring Framework
  • Build scalable, secure, and cloud‑native services that support multiple consuming applications
  • Contribute to microservice‑based, API‑driven architectures, following industry best practices
  • Participate in architectural discussions, influencing technology choices and design decisions
  • Write clean, well‑tested, maintainable code, adhering to agreed coding standards
  • Collaborate with engineering teams to continuously improve development processes
  • Support and contribute to DevOps practices, including CI/CD pipelines and automation
  • Participate in peer code reviews, knowledge‑sharing initiatives, and Agile ceremonies
  • Work effectively with both technical and non‑technical stakeholders to deliver business value

Your Skills

  • Strong experience in Kotlin or Java, with the ability and willingness to work across both
  • Proven experience developing RESTful APIs using frameworks such as Spring / Spring Boot
  • Solid understanding of microservices architectures and API‑driven design
  • Experience working with AWS or other cloud platforms, including cloud‑native services
  • Understanding of DevOps principles, CI/CD pipelines, and modern delivery practices
  • Experience working in Agile delivery environments (Scrum/Kanban)
  • Strong analytical, problem‑solving, and troubleshooting skills
  • Good communication skills and the ability to collaborate effectively across teams
  • Experience with test automation frameworks
  • Familiarity with Jenkins pipelines
  • Exposure to event‑driven architectures
