Senior Generative AI Engineer
London (2 days per week on-site)
Up to £110,000 + bonus + benefits
Permanent, hybrid (2 days in London)
Method has partnered with a UK technology consultancy pushing the boundaries of applied generative AI-scaling agentic, goal-driven systems into production.
We build intelligent agents that integrate directly into core business systems-CRM, ERP, service, and operations-so technology acts, learns, and improves continuously. Our work goes beyond static models to deliver autonomous, measurable business impact.
To accelerate this capability, we're hiring a Senior Generative AI Engineer to design, build, and deploy next-generation AI ecosystems for global enterprises. You'll join a hybrid London team (two days a week on-site) with strong flexibility for remote work.
Your Role
Design, build, and deploy generative AI systems (LLMs, retrieval-augmented architectures, embedding pipelines, agents) from prototype to production.
Lead the full ML lifecycle: data extraction, modelling, fine-tuning, training, inference, deployment, and monitoring.
Collaborate with product, engineering, and data teams to translate business needs into working AI solutions.
Establish standards for prompt engineering, model evaluation, and responsible AI (governance, bias mitigation, safety).
Optimise models for scalability, latency, cost, and accuracy in live environments.
Mentor engineers and raise the overall technical bar of the team.
You Bring
5+ years of ML/AI engineering experience, including 3+ years deploying generative AI (LLMs, fine-tuning, RAG) in production.
Strong technical grounding in Python, TensorFlow/PyTorch, transformer architectures (GPT, Llama, Mistral), vector databases, and prompt engineering frameworks.
Proven record of delivering measurable ROI from AI projects.
Solid engineering fundamentals: version control, CI/CD for ML, observability, API integration, and cloud infrastructure (AWS/Azure/GCP).
Confident communicator able to explain complex trade-offs to non-technical stakeholders.
UK-based and available for two days per week in the London office.
Why Join
Competitive base up to £110k plus bonus and benefits.
Hybrid setup: two days in London, remainder remote.
Direct influence on technical roadmap and AI strategy, not just delivery.
Opportunity to move beyond experimentation and define how generative AI operates at enterprise scale.
To Apply
Send your CV along with a one-page summary of your most significant generative AI project, highlighting the problem, approach, outcome, and measurable results.
