Job description

The Role

We're looking for an AI Engineer to build the agentic core of our product. You'll work closely with our CTO and own LLM-based features and agentic workflows end to end, from the agent framework through to the tooling that connects it to a customer's ERP. You’ll ship the cutting edge models and paradigms to Fortune 500 procurement teams.

Procurement is a demanding domain for agents: long-running workflows over messy data, where a wrong answer costs a customer real money. You'll decide how multi-agent collaboration works here, and how we benchmark it for performance, safety and behaviour.

We're building next-generation agentic systems that can manage entire procurement workflows, with a mission to make global manufacturing supply chains more resilient to an ever-changing world. That's a $3tn market opportunity.

We're backed by world-class investors including Sequoia Capital, and you'll be joining a team bringing together experience from OpenAI, Meta, Revolut, NASA and McKinsey.

What You’ll Do

• Own development and deployment of LLM-based features and agentic workflows end-to-end

• Develop new agentic frameworks to handle multi-agent collaboration.

• Benchmark LLMs across performance, safety and behavioural monitoring.

• Operationalise AI features by building tools to connect them to customer systems

• Collaborate with customers and internal teams to understand customer problems and design optimal solutions

You Might Be a Great Fit if You

• Have engineering experience at tech and product-driven companies, so you know what great code looks like

• Have experience shipping LLM-based solutions to production

• Have a deep understanding of the core technology behind language models, as well as computer science fundamentals

• Have built features end-to-end in Python

• Enjoy communicating with both technical and non-technical stakeholders.

Compensation and Benefits

At Magentic, we recognise and reward the talent that drives our success. We offer:

• Competitive Equity: play a real part in Magentic’s upside

• A salary of £90,000 - £110,000 per annum

• Enhanced parental leave

• 25 days holiday exc bank holidays, plus an extra day for our Christmas shutdown

• In-office lunches provided

• Salary sacrifice pension and nursery schemes

• Hybrid London HQ (3 days per week, with flex if you have appointments etc)

• Annual team retreat—a fully-funded off-site to recharge, bond, and build
