AI Native SW Engineering Specialist / Sr Consultant

£40.2 - £44.9 per hourEstimated

You build the systems that actually make AI work in enterprise environments, not demos, not prototypes that stall after a pilot, but production agentic architectures running inside real client organizations. The difference between an AI Engineer and what we are looking for is straightforward: you have shipped a multi-agent system in production, you have owned the eval harness, and you know what happens when your agent fails at 2am because you have lived it.

Key Responsibilities

  • Design and build production-grade agentic systems end-to-end: multi-agent orchestration, RAG pipelines, policy-based routing, tool invocation, memory management, and lifecycle observability
  • Build and own RAG pipelines: embeddings, chunking strategy, vector search, context window engineering and tuning against real quality targets
  • Integrate and abstract across multiple LLM providers - OpenAI, Anthropic, Vertex AI, and open-source models - with fallback routing, token, cost, and latency management
  • Implement LLMOps in production: eval harnesses with real quality metrics, prompt versioning, observability tooling (LangSmith, Braintrust, or equivalent), cost and safety monitoring
  • Embed directly with client engineering teams to design, prototype, and deploy agentic solutions - workshops, proofs of concept, code-with sessions, and architecture walkthroughs
  • Build reusable patterns, accelerators, and playbooks that scale beyond the individual client engagement and enable the next one to start faster
  • Define and use metrics to measure agent accuracy, latency, safety, and cost-effectiveness; present findings and recommendations to client stakeholders in business terms
  • Extensive software engineering experience in production environments
  • Hands-on experience designing and deploying agentic AI solutions in a production environment - non-negotiable
  • Demonstrated experience with agentic orchestration frameworks: LangGraph, CrewAI, AutoGen, or equivalent - at production depth, not tutorial level
  • Direct experience calling LLM APIs (OpenAI, Anthropic, Vertex AI) in production code: provider abstraction, token management, latency and cost tradeoffs
  • RAG pipeline ownership: embeddings, chunking strategy, vector databases, and context engineering
  • LLMOps fundamentals: eval harness design, prompt versioning, and production observability
  • Cloud-native engineering maturity: Kubernetes, Docker, microservices, serverless, CI/CD, and IaC (Terraform or Helm)
  • Strong Python; Java or equivalent backend language acceptable; production debugging and observability experience
  • Quality of experience is weighted over years, a candidate who has shipped three production agentic systems in four years is preferred over a generalist with passive AI exposure
