• 8+ years of production software engineering experience.
• Hands-on experience building LLM agents, agentic systems, or tool-using AI systems.
• Experience with multi-agent workflows, orchestration, tool/function calling, or autonomous systems.
• Strong software architecture and systems-engineering skills.
• Strong testing and evaluation mindset - including evals, regression testing, benchmarking, or drift monitoring.
• Demonstrated career progression in scope, ownership, or technical leadership.
• Startup, founding-engineer, 0→1, or highly autonomous engineering experience is highly valued.

Responsibilities

• Ship the first AI product from architecture through production
• Design agent orchestration and tool-using workflows
• Decide how work is split across agents and how concurrent changes are isolated and merged
• Build evaluation frameworks, regression tests, and drift checks
• Develop orchestration, evaluation, and codebase-analysis components
• Integrate AI workflows into real production codebases and CI/CD
• Solve challenging problems around concurrency, reliability, verification, and scale
• Provide technical direction and architecture guidance without direct reports

Job description

Senior Applied AI Engineer — AI Software Factory

We're building something new inside a Company - which isan AI Software Factory focused on fundamentally changing how enterprise software is built.

This is not a chatbot project.

The first product is an intelligence layer on top of complex legacy databases. From there, the team is developing an engineering model where multiple AI agents can plan, build, test, and review software components in parallel - with rigorous verification that the combined result works.

We're looking for a Senior Applied AI Engineer who wants to own the engineering standard for this new team.

What you'll do

• Ship the first AI product from architecture through production
• Design agent orchestration and tool-using workflows
• Decide how work is split across agents and how concurrent changes are isolated and merged
• Build evaluation frameworks, regression tests, and drift checks
• Develop orchestration, evaluation, and codebase-analysis components
• Integrate AI workflows into real production codebases and CI/CD
• Solve challenging problems around concurrency, reliability, verification, and scale
• Provide technical direction and architecture guidance without direct reports

What we're looking for

• 8+ years of production software engineering experience
• Hands-on experience building LLM agents, agentic systems, or tool-using AI systems
• Experience with multi-agent workflows, orchestration, tool/function calling, or autonomous systems
• Strong software architecture and systems-engineering skills
• Strong testing and evaluation mindset - including evals, regression testing, benchmarking, or drift monitoring
• Demonstrated career progression in scope, ownership, or technical leadership
• Startup, founding-engineer, 0→1, or highly autonomous engineering experience is highly valued

This role is NOT for

• Prompt engineering only
• Chatbot-only development
• AI experimentation without production deployment
• Research-only backgrounds without significant software engineering experience

Why join?

• Join a small, flat, high-autonomy team inside a global enterprise
• Work directly on an AI-native engineering model
• Own architecture and engineering standards from the ground up
• Work on genuinely difficult problems involving agents, concurrency, evaluation, verification, and legacy systems
• Influence how software is built at enterprise scale
• Work with a team that values engineering judgment over bureaucracy

No visa sponsorship available - candidates must hold ILR, British Passport or EU settlement

If you've built production software for years and are now pushing into agentic AI, we'd love to hear from you.
