You’ll design, build, test, and deliver production-ready software across the full development lifecycle, working closely with architects, principal engineers, and stakeholders to shape platform capability and technical direction.

This is a hands-on leadership role where you’ll drive best practices, guide engineering standards, and play a key part in modernising and scaling distributed systems.

• Designing, developing, testing and implementing high-quality Java microservices

• Working across the entire system lifecycle with a permanent feature team

• Collaborating with architects and principal engineers to align platform strategy

• Applying Agile practices to refine and deliver backlog items

• Building software with a strong focus on automation (build, test, deploy)

• Contributing to intentional architecture and driving emergent design

• Experimenting, prototyping and pushing new ideas to improve resilience and performance

• Ensuring solutions are secure, scalable, observable, and optimised for long-term use

• Supporting distributed workloads across public and private cloud environments

What You’ll Need

• Solid experience building microservices and distributed systems

• Proven track record delivering well-tested, production-ready code in critical environments

• Strong understanding of modern development practices:

• security

• performance

• observability

• availability

• Experience running production workloads across cloud platforms (public or private)

• Ability to break down complex requirements into clear and actionable technical components

• Excellent communication skills and comfort working closely with business and technology teams in Agile settings

• Experience working on backend systems that support mobile platforms is highly advantageous

• Join a major digital banking organisation impacting millions of mobile customers

• Work on modern Java microservices at scale

• Lead technical delivery in a highly skilled engineering environment

• Strong career growth opportunity with access to enterprise technology, modern tooling and principal-level mentorship
