Senior Java Developer / SRE Specialist

Company: GL Global
Apply for the Senior Java Developer / SRE Specialist
Location: Greater London
Job Description:

We are seeking a Senior Java Developer with strong SRE expertise to join a major production management transformation programme within a global investment bank.

This role sits at the intersection of software engineering and site reliability, with a focus on modernising how critical banking platforms are designed, built, and operated at scale.

We are specifically looking for a hands‑on Java expert who combines deep architectural knowledge with SRE principles – someone who can design robust systems while actively contributing to code, automation, and reliability engineering in a highly regulated environment.

You will play a key role in shaping resilient, scalable Java-based platforms, driving engineering standards, and embedding SRE practices across mission‑critical systems.

What You’ll Be Doing

  • Develop high‑availability, low‑latency Java-based systems for critical banking applications
  • Lead hands‑on development of reliability tooling, automation frameworks, and platform services
  • Embed SRE principles (SLIs, SLOs, error budgets) into system design and operations
  • Drive observability strategy (monitoring, logging, tracing) across distributed systems
  • Design and implement resilient microservices architectures (Spring Boot, event‑driven systems, APIs)
  • Own and improve CI/CD pipelines and release engineering practices

Experience

  • Strong experience as a Java Architect / Senior Java Engineer within large‑scale, distributed systems
  • Proven background in SRE, Production Engineering, or DevOps‑focused roles
  • Deep expertise in Java (Spring Boot, microservices architecture, REST APIs)
  • Strong experience with Kubernetes and containerised environments
  • Experience with Infrastructure‑as‑Code (Terraform, CloudFormation, etc.)

If you are a Java‑focused architect who thrives in hands‑on engineering environments and brings a strong SRE mindset around reliability, scalability, and automation, this is an opportunity to shape the future of critical financial systems at scale.
