About this role

Role Overview

IRIS Software Group is seeking a Principal Engineer for Agentic AI to play a pivotal role in accelerating the adoption of AI-driven, agentic software development across its engineering organisation. This remote position within the UK suits an experienced software engineering professional who 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.

Key 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.
Diagnose and debug specific blockers teams encounter with agentic adoption, such as tooling configuration, context engineering, workflow integration, or mindset challenges.
Build and maintain a living body of best practice, actively sharing insights across the engineering community and leadership cascades.
Partner with the Director of Enterprise Agility and Agile Coach team to ensure technical and human change elements of adoption are aligned.
Collaborate with the Director of Agentic AI on training content, tooling setup, and ongoing programme evolution by providing ground-level feedback.
Support configuration and integration of agentic tooling within divisional environments, including Model Context Protocol (MCP) integration, IDE setup, and workflow automation.
Evaluate agentic tooling options such as Cursor, Claude Code, and GitHub Copilot against real adoption data and hands-on usage.
Create, maintain, and share a library of common agentic skills, reusable prompts, skill definitions, and automation patterns.

Requirements

Deep, hands-on experience with agentic development tooling in a professional engineering context, such as Cursor, GitHub Copilot, or Claude Code.
Strong software engineering background across at least one primary language and stack with the ability to pick up unfamiliar codebases quickly.
Experience working across multiple teams or contexts simultaneously in a consultative or enabling capacity.
A proven track record of solving real engineering problems collaboratively alongside development teams.
Familiarity with modern software delivery practices including CI/CD, trunk-based development, automated testing, and observability tooling.
Comfortable with context-switching, ambiguity, and building trust rapidly across various team cultures and codebases.

Nice to Have

Experience with MCP server configuration, tool integration, or agentic workflow automation beyond IDE-level tooling.
Exposure to prompt engineering, agent orchestration, or multi-agent system design at a practical level.
Experience working in a B2B SaaS or multi-product software organisation with a mix of modern and legacy codebases.
Familiarity with the team topologies model and enabling functions within a distributed engineering organisation.
Experience in regulated or compliance-sensitive software environments such as accountancy, payroll, HCM, or education.
