We're a Great Place to Work® certified employer, recognised for our commitment to well-being, inclusion and development - and we're growing fast. IRIS is seeking a Principal Engineer to play a pivotal role in accelerating the adoption of AI-driven, agentic software development across its engineering organisation. As part of the Engineering Transformation Programme, this individual contributor role combines deep technical expertise with hands-on enablement, working directly alongside engineering teams to embed new AI-powered development practices into day-to-day delivery. Rather than focusing on training alone, the role bridges the gap between learning and adoption. The successful candidate will work across multiple product divisions, helping teams overcome real-world challenges, while shaping best practices, influencing programme strategy, and driving measurable improvements in engineering productivity. This is a highly visible position, partnering closely with senior leaders across Engineering, Agility, and AI transformation, and offers the opportunity to help define the future of software development at IRIS. Core responsibilities: - Embed directly with pod teams across divisions following bootcamp completion, working alongside engineers on real delivery work and enabling adoption of agentic tooling and workflows. This is hands-on engineering, not observation. - Diagnose and debug the specific blockers teams encounter with agentic adoption - whether that is tooling configuration, context engineering, workflow integration, codebase-specific challenges or confidence and mindset. Solve problems with teams, not for them. - Build and maintain a living body of best practice: what works, what does not, what is codebase or context-specific versus universally applicable. Actively share this across the estate - through the engineering community, cascades to SLT and divisional leads. - Partner with the Director of Enterprise Agility and the Agile Coach team to ensure the technical and human change elements of adoption are joined up. Where an adoption challenge is partly a ways-of-working problem and partly a tooling problem, work across both. - Partner with the Director of Agentic AI on training content, tooling setup and the ongoing evolution of the agentic programme - providing the ground-level feedback loop that keeps programme design connected to what actually benefits the teams. - Support the configuration and integration of agentic tooling within divisional environments - including MCP integration, IDE setup and workflow automation - to the point where teams can self-serve and maintain it. - Evaluate agentic tooling options - Cursor, Claude Code, GitHub Copilot and emerging alternatives - against real adoption data and hands-on usage from embedded assignments to help shape the programme's tooling decisions with evidence-based recommendations. - Create, maintain and share a library of common agentic skills and workflows - reusable prompts, skill definitions and automation patterns - so that teams across divisions can adopt proven approaches directly rather than rebuilding them from scratch. - Act as the go-to expert across the engineering estate for agentic engineering questions. Be genuinely reachable and collaborative. - Operate across multiple divisional contexts over time, moving between assignments as adoption matures in one area and the need shifts to another. Comfortable switching context, picking up unfamiliar codebases, and building credibility quickly with new teams. What Success Looks Like: - Sustainable team adoption of agentic development practices, with bootcamp graduates u
