AI Engineer

AI / GenAI Engineer (Contract)

Our client, a leading British airline, is scaling AI across its business. They are hiring AI/GenAI Engineers to build production-grade AI that works in real operating conditions.

Location: Heathrow Type: Contract

The role

This is a software engineering role specialised in AI, not a prompt-writing or experimentation-only position. You'll build, evaluate, and operate AI applications, agents, and reusable tooling that other teams can build on.

What you'll do

Implement agents, AI-assisted workflows, retrieval systems, and model integrations

Build the deterministic tools and APIs agents use to interact with enterprise systems

Develop automated evaluations for quality, safety, reliability, and regression detection

Implement guardrails, permissions, traceability, fallback, and human-escalation mechanisms

Monitor cost, latency, behaviour, and business outcomes

Diagnose production failures and keep improving performance

Contribute reusable components, standards, and reference implementationsWhat you'll bring

Strong software engineering fundamentals: APIs, cloud systems, testing, and production operations

Practical knowledge of LLM application patterns

A habit of improving systems through measurable evaluation, not subjective demos

Multiple seniority levels are considered, but the engineering fundamentals are essentialIdeal candidates from strategy consulting backgrounds

We're keen to hear from engineers who have built their careers in the technology and AI arms of firms such as McKinsey (QuantumBlack), BCG (BCG X), or Bain. You'll understand how AI creates value for the business, communicate clearly with non-technical stakeholders, and are used to delivering under client pressure. You should also be a hands-on builder who ships and operates code, not only someone who advises on it.
