Senior Software Engineer, AI Agents

Company DescriptionBefore you apply This is a hands-on production role, not a research or prototyping one. Please only apply if you've personally built or been a core builder on a system that's live with real users — not a demo, hackathon, or personal project.You should be able to speak in depth, from direct experience, to most of the following:You've built an agent or LLM system that takes actions against business systems — calls APIs, updates records, triggers workflows — not one that only answers questions from documents.You've shipped Go (or Java or similar languages) in a production backend (be specific about which, and how much).You've worked with a service-to-service orchestration tool such as n8n, Temporal, MuleSoft, Apache Camel, or Boomi.You've operated an API gateway (Kong, Tyk, or similar) in production.You've built or run a system serving multiple tenants/customers on shared infrastructure.You've built or used an evaluation framework to validate AI output quality before it shipped — not just spot-checked it.If your AI experience is mainly demos, personal projects, or wiring a single LLM call into an app, this role is above that level.IFS is a billion-dollar revenue company with 7000+ employees on all continents.

Join Team Purple. Join IFS.Job DescriptionBuild 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.
