Senior Forward Deployed Engineer

Senior Forward-Deployed Engineer - AI / LLMs - Early stage Start-up

London, with travel to customers weekly as required.

We’re supporting an AI Infrastructure start-up that helps organisations turn their own data into AI models and deploy them in their chosen environment.

As customers move into production, the team is hiring a Senior Forward-Deployed Engineer to own the technical journey from initial discovery through to deployment and ongoing adoption.

This is a hands-on engineering role with significant customer interaction. You’ll work alongside sales and engineering, building tailored demonstrations, validating model performance and helping customers get real workloads into production.

What we’re looking for:

• Strong hands-on experience with open-weight LLM post-training, including fine-tuning techniques such as LoRA and supervised fine-tuning.
• Experience designing evaluations and balancing model quality, latency and inference costs.
• A track record of shipping models into production for real users.
• Strong Python skills, with experience across GPU infrastructure, containers and distributed workloads using tools such as Ray or Kubernetes.
• Confidence leading technical conversations with CTOs and explaining trade-offs to commercial stakeholders.
• A background in forward-deployed, solutions or applied engineering, or a related role combining technical delivery with customer engagement.
• Based in London and able to travel to customers as needed.

Useful additional experience:

• Financial services or other regulated customer environments.
• Data residency and regulatory requirements.
• Working across multiple GPU providers and sizing workloads to hardware.
