Senior AI Engineer

Senior / Staff AI Engineer (Python, ML Systems) - FULLY REMOTE

High-growth AI |

We're working with a well-funded, fast-scaling AI company building a highly ambitious product at enterprise scale. They're now looking to add Senior and Staff-level AI Engineers to help shape the next phase of their ML platform and establish strong technical leadership within the team.

This is a product engineering role (not consultancy, not internal tools) with a heavy focus on ML systems, model deployment, and production AI infrastructure.

What you'll be doing

• Designing and building production ML systems and pipelines in Python
• Architecting scalable inference infrastructure and model serving systems
• Building robust MLOps tooling for training, evaluation, and deployment
• Owning AI system reliability, performance optimization, and monitoring at scale
• Acting as a technical leader within the AI engineering team, with a clear path to Staff / Tech Lead impact
• Helping lay the foundations for significant product and engineering growth over the next 12-18 months

• Senior or Staff-level AI/ML engineer (roughly 10-12+ years' experience)
• Expert Python skills with deep ML frameworks experience (PyTorch, TensorFlow, or similar)
• Proven experience running production ML systems at scale
• Strong background in model deployment, MLOps, and ML system architecture
• Experience with LLMs, transformers, or modern AI architectures
• Comfortable making long-term technical decisions around ML infrastructure
• Experience in regulated or enterprise AI environments is a plus
• Strong software engineering fundamentals (not pure research)

Strong positive signals:

• Solid tenures at companies running ML/AI at real scale
• Clear career progression into senior AI technical responsibility
• Background in production ML platforms or high-traffic AI products

Team & environment

• Small, high-calibre engineering team (~8 engineers)
• Fast-paced, high-ownership culture
• Serious technical ambition - strong people to learn from, but expectations are high
• Backed by recent oversubscribed funding and a very strong customer pipeline

• Senior: ~£100k-£125k
• Staff: up to ~£130k (target level)
• Meaningful equity at an early stage
• Clear growth trajectory as the company scales toward Series A

If you're an AI engineer who thrives on turning models into products, building robust ML systems, and technical leadership, this is a rare opportunity to get in early and have genuine influence.
