Senior Ruby Developer in London

About us
We’re Transform. Transform is a fresh alternative to Big Consulting. As an end-to-end transformation partner, we define, design, build and operate systems that solve our clients' toughest challenges and seize their biggest opportunities. That often means combining strategy, data, AI, technology, and change management. Sometimes we manage and operate the systems we create; other times, we hand it over for the client to run – standing by to make improvements when things change. It all comes down to making an impact: improving lives, supporting citizens, streamlining workflows, and making the world a better place. We specialise in public sector and public-facing organisations—from government agencies and local authorities to energy, utilities, transportation and healthcare. We also work for some of the world's most dynamic brands across automotive, retail, financial services, and consumer goods. In 2024, Transform acquired Cadence Innova, the UK's leading public sector change consultancy. The result is a fresh kind of partner: together, we're able to deliver change from the very first ideas through to deployment—building on our deep relationships at every level of government. We're part of the Next 15 group, a multi-national organisation spanning over 25 brands. We combine the financial robustness and breadth of services of a large organisation, with the nimbleness and innovation of a smaller brand. If you are keen to help us build the workforce of the future, we should talk. We're all in. That's what gets us out of bed every day. We hope you feel the same.
