This is a highly visible, business-critical programme.

• Strong Ruby on Rails experience (Senior/Lead level)
• Proven Azure experience
• Experience leading engineering teams
• GDS delivery experience (Alpha, Beta, Live services)
• Strong communicator, comfortable advising senior stakeholders
• Agile delivery background
• Experience working within UK government digital standards (desirable)

• Inside IR35
