Applied AI Engineer

Summary

Builds AI-driven systems for session/context management, retrieval, agentic workflows, and evaluation in a SaaS product, integrating speech/images, optimizing for latency/cost, and ensuring security/autonomy. Core tech: GenAI (RAG, agents), Go/Python, MCP, LangChain, Kubernetes, and API gateways.

Build the intelligence behind the experience: the session and memory model, retrieval across our own estate and the documents that run it, the agentic flows that carry out multi-step work, and the evaluation that tells us whether any of it is right.

What you will do

  • Build the session and context spine: persistence, resumption, hand-over with the reasoning trail intact, and context resolved from a person's identity and entitlements.

  • Build retrieval and grounding across structured records and documents, at a cost and latency the product can afford.

  • Build document intelligence over manuals, engineering drawings, certification directives and contracts, extracted and citable, because for many of our customers those carry as much operational truth as the databases.

  • Build the agentic flow runtime: multi-step work with tools, and the rules that decide when a human is asked rather than told.

  • Handle speech and images as first-class input alongside text, so the same request works dictated in a plant room or photographed at an asset.

  • Build the evaluation harness, and treat it as the gate on every claim we make about autonomy.

  • Build the language interface over our scheduling and optimisation engines, expressing trade-offs in the customer's own terms.

  • Build the security layer with our security team: resistance to prompt injection, personal data handling, guardrails, audit and data residency.

  • Experience with S2S integration, preferably using technologies such as n8n or Temporal, or alternatively MuleSoft, Apache Camel, or Boomi.
  • Experience with Go and Python.
  • Experience building multi-tenant SaaS solutions.
  • Experience building and scaling AI-native products and applications.
  • Experience with production-grade GenAI solutions, including RAG pipelines (hybrid retrieval, embeddings) and agentic systems (agent orchestration, tool usage).
  • Experience with AI frameworks and tooling such as Pydantic AI, LangChain, and MCP.
  • Experience with MCP development and plan-based agentic software development.
  • Experience with DevOps and cloud-native infrastructure, including Docker, Kubernetes, CNCF technologies, and CI/CD pipelines.
  • Experience with API gateways and API products, preferably with platforms such as Kong or Tyk.
  • Preferably experience optimizing AI services for latency and cost.
  • Preferably experience with specification-driven development.
  • Passionate about and eager to adopt new technologies.
  • Up to date with the latest developments in GenAI and AI-based software development.
