Senior Software Engineer

MCS Group is working exclusively with a high growth product-focused technology company as they seek to scale their engineering team in Belfast. We're looking for a senior software engineer who is eager to work on products that actually get used and are genuinely changing how an industry operates. This is a great opportunity to join a high-growth tech team building the core services and applications that power a major cloud platform used across a global, high-profile customer base. We're specifically interested in speaking with senior software engineers with a strong foundation in back-end development (Java specifically) and exposure to cloud technologies.

This is a role well suited for software engineers who like owning things end-to-end - from React SPAs to Java/Spring services, from infrastructure-as-code to production releases. If you enjoy problem-solving, learning fast, and leaving things cleaner than you found them, you'll fit right in.

Please note that this is a Belfast based role with a hybrid working model.

What you'll do

• The Senior Software Engineer will ship new features across the full stack - front end, back end, and the cloud that holds it all together.
• You'll run your own services: pipelines, deployments, monitoring, reliability
• You'll lean into automated testing to keep quality high and releases smooth
• Work closely with product, UX, architects, and platform engineers to deliver well-designed software.
• Contribute to improving CI/CD and the engineering playbook
• Tackle production issues with a cool head and a systematic approach
• Use AI-assisted development tools to boost speed and refine solutions
• Mentor peers and help raise the technical bar across the engineering organisation in Belfast and beyond.
• Keep an eye on emerging tech and get the chance to bring fresh ideas to the table

What you bring

• Strong commercial experience in Java.
• While this will be more back-end leaning (ie. 70/30 split) you'll ideally have hands-on skills with React/TypeScript/Node and modern front-end frameworks.
• Solid automated testing practices
• Working knowledge of cloud platforms (AWS ideal), containers, and Kubernetes
• Confident with SQL and performance-aware query design
• Comfortable navigating CI/CD and automating the boring stuff

The tech stack you'll touch

Java, Spring Boot, React, Python, Terraform, Kubernetes, Jenkins, Postgres, DocumentDB, AWS.

Salary

Up to £80,000 depending on experience with a leading benefits package.
