Java Engineer

Hybrid, 2 to 3 days a week in Welwyn Garden City.

Build high traffic, event driven systems.

Full ownership of your services, end to end, not handing off to ops.

Modern stack, Java and Spring Boot on Azure with Terraform and microservices.

Real route to broaden into platform engineering.

Salary up to £80,000 depending on experience.

We are supporting a fast-growing global technology consultancy, in triple digit growth, that builds and delivers software for some of the biggest brands in the world. For this role you would be building for one of the largest names in UK retail, on systems that run at a scale most product teams never see. This is an environment where engineers take genuine ownership of what they build, with a real DevOps culture and the chance to broaden their skills rather than stay boxed into one corner of the stack. If you want to own your work end to end and build at real scale, this is for you.

As a Senior Java Engineer, you will design, build and own backend services in Java and Spring Boot, working on high traffic, event driven systems where reliability and performance genuinely matter. This is a hands-on, high-ownership role where you take full lifecycle responsibility for your services, from development through deployment and support, with scope to move into platform work over time.

Key Responsibilities:

• Design, build and maintain backend services in Java and Spring Boot.
• Work with event driven architecture and high traffic, distributed systems.
• Build and run services on Azure, using Terraform and infrastructure as code.
• Take full lifecycle ownership, from development to deployment and support.
• Maintain high testing standards and clean, maintainable code.
• Collaborate with the wider team to deliver robust, scalable solutions.

Essential Experience:

• Strong backend Java and Spring Boot experience built in production environments.
• Solid microservices and event driven architecture, ideally with Kafka or similar.
• Cloud and infrastructure as code experience, Azure and Terraform ideally, though strong AWS plus Terraform transfers.
• A genuine ownership mindset and strong testing discipline.
• Any payments, fintech or other regulated, high volume background is a real plus.
• Right to work in the UK, no sponsorship is available for this role.

What's on Offer:

• Salary up to £80,000 depending on experience.
• The chance to build for a major retail brand inside a consultancy in triple digit growth.
• Full ownership across your services and a real route into platform engineering.
• A modern stack and a genuine DevOps culture.
• Hybrid working, 2 to 3 days a week in Welwyn Garden City.
