Principal AI Software Engineer
£725-800 per day
London x1 day per week in St Pauls
6 month initial contract Inside IR35
The opportunity
This is a contract engagement supporting a major Information Security AI transformation, a large programme that is modernising and automating the security operating model with agentic AI. We are looking for a hands-on engineering leader to drive the build of a portfolio of agentic AI security applications, defanging the solution architecture and contributing to the most complex components of the solution and system design.
You would work with a good deal of autonomy to deliver a defined set of outcomes, on complex and current problems in AI security, and collaborate with software and solution architects to define target architectures, and coordinate workloads of software engineers as well as being hands on.
What you would deliver
- Technical leadership of the build, turning the target architecture into production quality software across a portfolio of agentic AI applications, APIs and services.
- Engineering standards, DevSecOps practice and a secure development lifecycle, integrated with the organisation's established central CI/CD platform, pipelines and golden paths.
- An AI-native software delivery operating model built on agentic harnesses and automation.
- Reusable frameworks, libraries and platform capabilities that speed up delivery and keep security built in by default.
- Delivery of the most complex components and integrations across our agentic roadmap.
- Technical assurance through code review, quality standards and mentoring, to raise the engineering bar.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Skills and experience
- Extensive practical software engineering experience, including leading engineering teams technically and delivering complex, production quality systems at scale.
- Deep, current experience building agentic AI applications, including LLM orchestration, retrieval augmented generation, tool and function calling, MCP, memory, evaluation and agent harnesses, in Python or TypeScript.
- Demonstrable knowledge of Langgraph agentic development frameworks.
- A track record of implementing or evolving engineering standards, DevSecOps practice and a secure development lifecycle, and integrating with a central CI/CD platform, pipelines and golden paths.
- Experience defining or evolving an engineering operating model and ways of working, ideally an AI native model built on agentic harnesses and automation, or software factory concepts.
- Experience delivering on cloud platforms, ideally AWS, with containers and Infrastructure as Code.
- A solid grounding in secure by default engineering, observability and production operability, with practical knowledge of AI security practices such as the OWASP Top 10 for LLM and Generative AI applications and OWASP guidance for agentic AI.
