About Scrumconnect Consulting

Scrumconnect Consulting is a leading UK digital and technology consultancy, partnering with central government and major financial institutions to deliver high-impact, complex technology programmes. We bring deep engineering expertise, a strong delivery culture, and a genuine commitment to quality. With a team of 125+ engineers, architects, and delivery professionals — 42% of whom are women — we are proud to build teams that reflect the diversity of the clients and citizens we serve.

About the role

You will join Scrumconnect Consulting as a Senior Java Engineer specialising in ICON IPF, working directly with major banking clients to design, build, and deliver large-scale payment modernisation programmes. This is a technically deep, hands-on role — you will be writing production Java code, configuring and extending the IPF framework, and working within cloud-native microservices architectures built on AWS.

You will be embedded in client-facing delivery teams, collaborating closely with both technical engineers and non-technical banking stakeholders. Strong communication skills and the ability to translate complex payment domain concepts are as important as engineering excellence.
