Senior AI Engineer x 2 Contract - Outside IR35 - 6 months+ Oxfordshire OR London £700 - £900 per day DOE Our client is a rapidly scaling UK deep-tech company delivering advanced AI capability into some of the most consequence-heavy environments there are: defence and national security, critical national infrastructure, and enterprise clients whose decisions carry real weight. They're hiring two Senior Applied AI Engineers to take ownership of the agentic AI systems underpinning their platform, on a contract basis, with genuine influence over how those systems are architected and delivered. This role suits an engineer who designs and ships systems rather than assembling pre-built components - someone who cares more about how a system performs once it's live and under pressure than how impressive it looks in a demo. What You'll Be Doing Architecting and building multi-agent AI systems end-to-end, combining frameworks such as LangGraph or Haystack where they add value with...

Role: Senior Applied AI Engineer (Private Sector Contractor) Rate: £700–£900 per day, dependent on experience Location: Hybrid: 2 days a week on site at Harwell, Oxfordshire; remainder remote (UK-based) Engagement: Contract, outside IR35: initial [6]-month term with strong likelihood of extension Start: Immediate Start   A note from the Founders   Oxford Dynamics is at an inflection point. We build frontier AI for environments where the cost of a wrong decision is high: defence and national security, critical infrastructure, and commercial organisations making high-stakes decisions on complex data. We are growing fast, and the constraint on how fast is no longer ideas or opportunity. It is whether the systems we ship are good enough for the people who stake decisions on them. That is where you come in. We need engineers who can build the systems this mission depends on, and build them to a standard that...
