We’re looking for AI operators who ship — not experiment. This is an opportunity to join a major AI build focused on deploying real-world LLM and agentic systems at scale across both AI products and enterprise transformation initiatives. You’ll be working in a production-first environment where the emphasis is on building reliable, scalable AI systems that deliver measurable business impact.

What You’ll Be Working On

  • Designing and building AI agents and agentic workflows powered by LLMs
  • Developing systems using RAG, reasoning, planning, memory, and tool orchestration
  • Building multi-step intelligent systems capable of real-world tool usage
  • Working with MCP-style architectures (or equivalent) to structure context and improve interoperability
  • Contributing to recommendation, classification, and forecasting systems using large-scale datasets
  • Automating business workflows and decision-making processes through AI-driven solutions

What You’ll Be Doing

  • Owning projects end-to-end from concept through to production deployment and iteration
  • Building and deploying AI agents that operate reliably in production environments
  • Integrating AI systems into APIs, products, and operational workflows
  • Collaborating closely with engineering teams to ensure scalability, observability, and maintainability
  • Making pragmatic decisions balancing model performance, latency, and cost efficiency

Core Requirements

  • Strong Python skills with experience writing production-grade code
  • Proven experience deploying LLM-powered systems into production environments
  • Hands-on experience with LangChain, LangGraph, or equivalent orchestration frameworks
  • Experience building AI agents and agentic workflows with tool usage and multi-step reasoning
  • Strong understanding and implementation experience of RAG systems
  • Familiarity with MCP/FastMCP/FastAPI or similar orchestration patterns
  • Strong understanding of LLM trade-offs including hallucination mitigation, latency, and cost optimisation
  • Experience deploying AI systems in cloud environments such as AWS, GCP, or Azure
  • Working knowledge of SQL/data manipulation (Working knowledge of SQL or data manipulation is expected, but it is not a primary focus for this role.)

Strong signals include:

  • Experience working on SaaS or B2B AI products or delivering AI-driven transformation within an organisation.
  • A background in high-growth or scaling environments, where speed and pragmatism are critical.
  • Clear evidence of systems that are actively used and delivering value, rather than experimental work.

Ideal Background

  • Masters degree or higher in Computer Science, Mathematics, Engineering, or a related technical field
  • Experience building and iterating on AI systems delivering measurable value
  • Strong ownership mindset and ability to operate in fast-moving environments
  • Product-focused approach with a bias toward delivering impact

Why This Role

  • Work on live AI systems used at scale
  • Join a well-supported AI engineering environment
  • High ownership and visibility across products and operations
  • Opportunity to shape enterprise AI adoption in a meaningful way
