DWP. Digital with Purpose.

We need software engineers with skills in COBOL.

As a COBOL Software Engineer, you’ll join one of DWP Digital’s specialist engineering teams responsible for maintaining, modernising and transforming the core platforms that keep vital payments flowing to over 15 million people every year.

These systems - built using Microfocus COBOL - are at the heart of DWP’s operational stability, and your work will directly impact the availability, accuracy and resilience of services relied upon by millions.

This is a hands-on engineering role with real leadership impact. You’ll guide and develop a team of 5 engineers, drive technical direction across multiple applications and lead the modernisation of some of the most significant legacy services in government.

Over time, you’ll play a role in helping DWP transition these core systems into Java-based services, giving you continued exposure to new and emerging technologies.

The scale of what we do is extraordinary, and our purpose is unique. We’d love you to join us.

What skills, knowledge and experience will you need?

• Strong, hands-on experience working with Microfocus COBOL, especially building or maintaining large-scale systems.
• Awareness of additional technologies such as Tuxedo, Red Hat Enterprise Linux and scripting languages.
• Understanding of tools or languages like Python, Java, Ansible, Jira, and cloud platforms such as AWS.

• Understanding of automated testing and how it fits into continuous deployment environments.

You and your role

As a COBOL Software Engineer, you’ll be central to maintaining and modernising the platforms that deliver over £150bn in payments every year. These services are some of the largest and most important in the UK, and you’ll be responsible for ensuring they remain stable, secure and resilient.

You’ll work within our delivery teams, helping to lead refactoring work across some of our major COBOL applications, modernising how they operate today and preparing them for the strategic technology shift DWP is undertaking over the next decade.

This role has a strong leadership and development focus. You’ll coach and mentor junior engineers, support those progressing through our Engineering Academy, and help grow the next generation of specialist COBOL talent. You’ll also provide 3rd-line support when needed, resolving complex technical issues that require deep system understanding.

We can promise challenge and variety. One day you might be leading technical improvements to legacy codebases; the next, planning infrastructure maintenance, resolving live service challenges, or influencing how we deliver future modernisation programmes.

If you enjoy solving complex engineering problems and developing the next generation of engineering talent, then this is an opportunity to make a real impact and leave a long-lasting legacy on the future of public services.
