More:

We are a global technology-driven organisation scaling advanced AI capability across our UK engineering function. We have already invested heavily in enterprise AI platforms and Agentic AI frameworks, and we are now focused on driving adoption across engineering teams, establishing common engineering patterns, and enabling increasingly complex AI and ML solutions to operate safely and reliably in production. This is a senior hands-on Staff Engineer contract role based in London with 3 days per week on-site, an initial 6-month term, and a long-term programme roadmap. The contract is inside IR35 and offers a day rate of £800–1,200 inclusive. We are also actively adopting AI-assisted development tooling, including Claude, and are especially interested in engineers who are already using AI to improve their own software engineering workflows.
