We're recruiting experienced software engineers at Principal, Tech Lead and Senior levels for an established UK digital business transforming how it designs, builds, tests and delivers customer-facing products.
The business is moving towards empowered product teams and an agent-first software development lifecycle. These are hands-on roles for engineers who already use AI coding agents extensively to ship real production software, rather than simply experimenting with AI tools or developing standalone LLM applications.
The role
* Agentic Principal Product Engineer (£120,000 - £160,000): Help redesign the engineering lifecycle around AI agents, establish tools and guardrails, influence architecture and engineering standards across teams, and coach engineers while remaining hands-on with production delivery.
* Agentic Tech Lead (£90,000 - £120,000): Own technical direction and delivery within a cross
* functional product team, working with Product and Design to turn customer problems into production software using agentic workflows.
* Agentic Senior Product Engineer (£75,000 - £100,000): Build and improve web and mobile customer-facing products, take ownership of features from discovery to production, and use agents throughout implementation, testing and delivery.
* Across all levels: use AI coding agents as a core part of development, improve tooling and feedback loops, and champion testing, CI/CD, observability, security and reliable delivery.
* Work with Product and Design, prototype ideas quickly, measure customer and engineering outcomes, and share effective practices with colleagues.
What we're looking for:
You'll be an experienced, hands-on Software Engineer with strong full-stack fundamentals and substantial commercial experience using AI coding agents to deliver production software. We're particularly interested in:
* Demonstrable use of AI coding agents across real software development workflows, with specific examples of shipped work.
* Full-stack engineering, system design and sound architectural judgement.
* Automated testing, CI/CD, observability, secure delivery and maintainable production systems.
* Ability to create effective agent context, tooling, workflows and quality controls.
* Product thinking, customer focus and collaboration across Engineering, Product and Design.
* For Principal and Tech Lead: evidence of technical leadership, coaching and improvements to engineering delivery.
* For Principal: measurable before-and-after improvements in productivity, quality, delivery speed or cost.
Experience with custom agents, MCP integrations, modern web/mobile platforms, React, React Native, Expo, cloud-native services or legacy modernisation would be useful. Familiarity with tools such as Claude Code, Cursor or GitHub Copilot may be relevant, but demonstrable practical delivery matters more than the tool name.
What's on offer:
* Three seniority levels, with permanent salaries from £75,000 to £160,000 depending on role.
* Opportunity to help shape an agent-first engineering approach and modern product teams.
* Hands-on ownership of customer-facing products and measurable engineering improvements.
