# AI System Engineer

The role We are looking for a Senior AI Systems Engineer to build and operate the intelligence layer of our AI products. This is a software-engineering-led role, not a prompt-development role: you will make model, retrieval, tool and orchestration behaviour testable, evidence-grounded, observable and reliable in production. You will own the implementation of the product’s AI systems, including model integration, retrieval and context assembly, multi-step workflows, evaluation instrumentation, provenance mechanics and failure handling. What success looks like · AI outputs are grounded in data, and their supporting sources can be inspected wherever the risk tier requires it. · Task, retrieval, citation and workflow quality are measured through repeatable evaluation and regression suites, with hooks exposed for independent evaluation. · Prompts, models, orchestration logic, datasets, configurations and evaluation assets are versioned production artefacts. · Known failure modes have explicit controls, abstention or escalation behaviour, and observable operational signals. What you’ll do · Design, build and operate foundation-model, retrieval and workflow services that solve the product
