Senior Engineer – Platform Engineering (APIs)

At Metro Bank, we believe the best banking experience starts with people who genuinely care. We’re not just delivering banking services - we’re building trust through authentic connections. Here, our people come first; our colleagues are part of a team that values individuality, collaboration, and long-standing relationships. We are also all about balance so most of our jobs offer the opportunity for hybrid working built around your role and home life, wherever possible.

As a Senior Engineer – Platform Engineering (APIs) you will be responsible for leading the evolution of our API ecosystem across Azure and Rackspace Kubernetes, integrating with core services in AWS and legacy Rackspace systems. This role will shape how we expose microservices, modernise integration patterns, and ensure secure, scalable, resilient API delivery.

What you will do:

• Lead API platform engineering using Kong, Kafka and microservice patterns on Kubernetes.
• Design and optimise API gateways, event flows and service interactions across multi cloud stacks.
• Ensure reliability, observability and performance for business critical integrations.
• Partner with product and backend teams to enable new capabilities via secure, modern interfaces.
• Mentor engineers, set engineering standards and drive adoption of best practices.

And... we are a bank so risk is a part of everything we do. We love people who take responsibility, do the right thing for customers, colleagues and Metro Bank and have the ability to call out any concerns.

What you will need:

• Strong experience with API gateway technologies and event streaming.
• Deep understanding of Kubernetes in Azure and hosted environments like Rackspace.
• Strong microservice engineering skills across networking, security, scaling and interoperability.
• Experience integrating cloud native systems with legacy backends across multi cloud.
• Solid engineering leadership and ability to set platform wide standards.
• Understand the risks associated with your job and what that means for you, Metro Bank and all our stakeholders.

We will give you the training to ensure you succeed in your role and plenty of internal opportunities to progress your career (around 40% of our recruitment comes from internal promotions!)

Diverse teams really are the best teams. We know that candidates (especially women, research tells us) may be put off applying for a job unless they can tick every box.

So if you are excited about working with us and think you can do much of what we are looking for but aren’t sure if you are 100% there yet… why not give it a whirl?
