Lead AI-First Software Engineer
Type: contract
Day rate: £600 per day (outside IR35)
Location: Liverpool (2 days per week)
From the CTO:
"We're embarking on a major modernisation programme for one of our core business platforms. An internal proof of concept has already demonstrated what's possible using AI-assisted engineering. Your role will be to take that concept into production, creating a scalable engineering approach that accelerates software delivery while maintaining high standards of quality, security and maintainability."
This isn't a traditional Senior or Lead Engineer role. We're looking for someone who sees AI as a force multiplier. This is about far more than migrating applications. It's about redefining how engineering teams build software utilising AI tools particularly Codex.
