Senior Software Engineer - AI, Agentic Development

Senior Software Engineer – AI, Agentic Development

Permanent – Hybrid Greater Manchester area

Join our client as a Senior Engineer, taking a leading role in shaping the next generation of AI-enabled software delivery. This position embraces emerging AI tooling, where you’ll design, build and augment intelligent agent-based workflows that transform how teams build, test, review and deploy software.

This is not about code re-use or simple code autocompletion. It’s an opportunity to act as a lead for a distributed ecosystem of ‘coding agents’, developing the logic, structures and governance that allow multi-agent systems to collaborate as part of a modern engineering function. If you’re excited by experimentation, advanced AI-assisted development, and driving best practice in a rapidly evolving space, this role offers a rare chance to influence engineering culture at scale.

Duties of the Senior Software Engineer will include:

• Design and implement multi-agent development workflows (e.g., writer, reviewer, tester, deployer agents).• Develop prompts, behavioural logic, and composition frameworks that guide autonomous coding agents.• Enable safe and structured agent access to tools such as file systems, source control, test harnesses, and internal APIs.• Evaluate and refine AI agent performance, assessing collaboration patterns, output quality, and feedback loops.• Lead and contribute to architectural discussions on AI-driven build systems, automated generation, and intelligent pipeline design.• Prototype new AI-powered developer experiences using LLMs, vector stores, and internal knowledge bases.• Partner with cross-functional teams on AI-enhanced tooling for internal users.• Help define AI evaluation standards; reliability, accuracy, velocity, impact.• Mentor others colleagues applying generative AI to real-world development workflows.

• Mentor others colleagues applying generative AI to UI prototyping and automation.• Champion secure integration of generative AI into regulated environments.• Participate in the engineering on-call rotation.

To progress in the Sen Software Engineer role, your experience should include:

• 5+ years’ software engineering experience across both backend and frontend stacks.• A strong proficiency in various development languages, inc; Java / TypeScript / React.

• Strong relational databases skills, ideally MySQL.• Practical experience using modern AI-assisted development tooling—such as Cursor, Windsurf, LLM APIs, code-generation frameworks, vector databases, and agentic platforms such as LangChain.• A product mindset focused on building tools & systems deliver real-world value.• A demonstrable focus on experimentation, iteration, continuous learning, and evidence-based decision-making.• Ability to operate effectively in regularly evolving, ambiguous environments and contribute to the creation of emerging standards and best practices.

Rewards & Benefits

• Competitive base salary commensurate with experience.• Hybrid working model aligned to team and project needs. (typically, 60% in office)• Comprehensive benefits package inc. pension, private health, dental & vision care.• Professional development pathways, including advanced technical training.• A highly collaborative working environment that values innovation, ownership, and continuous improvement.
