Lead / Senior Generative AI Engineer / AI Engineer / Artificial Intelligence / Generative AI / AWS / GCP / Engineering Mindset / London / Bristol / Manchester/ Birmingham / Cardiff / Cambridge / Oxford / England

Hiring via: 167 Solutions
Location: UK (Hybrid 12 days per week onsite)
Start Date: February (Interviews available immediately)
Employment Type: Permanent
Right to Work: Must already have the right to work in the UK (no sponsorship)

The Role

167 Solutions is partnering with a high-growth consultancy making a significant multi-year investment into Generative AI. This hire is critical. You will be one of the core technical leaders, responsible for hands-on delivery from day one, while also helping shape a new Generative AI Centre of Excellence (CoE).

This is not a strategy-only or advisory role.
This is a 24/7 hands-on engineering role, building, testing, deploying, and iterating production-grade GenAI systems at enterprise scale.

Everything is greenfield. No legacy constraints. No pre-selected vendors. You will help define the technical direction, tooling, and engineering standards while actively writing code and shipping solutions.

What Youll Be Doing (Hands-On)

• Design, build, and deploy Generative AI systems end to end from use-case discovery through to production
• Build Retrieval-Augmented Generation (RAG) pipelines using vector databases, embeddings, and enterprise data sources
• Develop agent-based workflows, orchestration layers, and multi-step reasoning systems
• Work extensively with open-source and commercial LLM ecosystems, including Hugging Face models and tooling
• Implement prompt engineering, evaluation frameworks, and performance optimisation strategies
• Architect secure, scalable GenAI solutions on AWS and GCP
• Build APIs, services, and pipelines to integrate GenAI into real business workflows
• Apply LLMOps / MLOps practices: versioning, monitoring, cost control, bias, and drift management
• Work directly with clients to translate business problems into deployable AI solutions, not slide decks
• Contribute to building internal IP, accelerators, and reusable frameworks as the CoE scales

What Were Looking For

• Minimum 3 years experience building and deploying Generative AI or applied ML systems

• Strong hands-on engineering background you actively code, build, test, and deploy

• Experience with:

  • RAG architectures and vector databases
  • Hugging Face models, pipelines, and inference tooling
  • Prompt engineering and LLM evaluation techniques
  • Agentic systems and orchestration patterns

• Cloud-native experience across AWS and/or GCP

• Comfortable working across multiple business functions (finance, ops, customer, HR, tech, data)

• Platform-agnostic mindset focused on methodology, workflow, and outcomes, not vendor lock-in

• Consulting mindset: able to engage stakeholders while staying deeply technical

• Experience operating at Senior / Lead / Manager level, or as the go-to GenAI engineer on projects

Why This Opportunity Stands Out

• Hands-on by design this is a builders role, not a steering committee role
• Greenfield GenAI practice with genuine freedom to architect properly
• Heavy investment committed over the next 2 years
• Enterprise-scale builds with real users, real data, and real impact
• Clear progression as the CoE grows in size and capability
• Hybrid working that balances autonomy with collaboration
