AI platform engineer in financial services in London

Описание:

(NewCo) is a new AI-native product organisation within Capgemini Financial Services. We build products, not projects: software for insurance claims and payment operations, sold to banks and insurers. Two product lines run on one shared platform, built by a deliberately small, senior team. Our engineering model is agentic: engineers author the specifications, tooling, evaluation suites, and guardrails, and AI agents do most of the implementation.

Задачи:

One or more platform components end to end: model gateway (routing, failover, caching, per-line cost attribution), agent runtime and orchestration, evaluation harness, guardrail engine, tool and agent registry, or shared product services The training and adaptation loop: pipelines that turn production traces and evaluation verdicts into reinforcement learning and fine-tuning datasets, and the infrastructure to train, evaluate, and serve NewCo-tuned LLMs and SLMs behind the same gates as vendor models Reliability, latency, and cost of what you build; platform services carry baselines and you hold them The self-service surfaces product engineers use: your components ship with documentation, sane defaults, and no ticket queue Co-building with product teams: new shared services start embedded with a product line and graduate to platform services when proven

Требования:

Strong production engineering: Python plus one systems language (Go or Rust welcome), Kubernetes, infrastructure-as-code, and one major cloud Hands‑on experience with LLM infrastructure: a model gateway pattern (such as LiteLLM or in‑house), model serving (such as vLLM or managed endpoints), and vector or retrieval systems Agent‑systems experience: you have built with an agent orchestration framework (such as LangGraph or first‑party agent SDKs) and understand tool calling and the Model Context Protocol (MCP) Evaluation engineering: you have built or operated eval harnesses (golden datasets, regression gates in CI, LLM‑judge calibration) and can explain why they gate merges Post‑training fluency: you have fine‑tuned or post‑trained a model, built the data pipeline behind one, or reproduced techniques from recent papers in production systems Daily, hands‑on use of AI coding assistants as part of your own development workflow Будет плюсом: Guardrail‑engine or AI‑observability experience (NeMo Guardrails, OpenTelemetry GenAI conventions, LangSmith, Braintrust, or equivalent); Reinforcement learning infrastructure (reward modelling, RLHF or GRPO‑class pipelines) or SLM distillation experience; Multi‑tenant SaaS infrastructure: tenancy isolation, metering, usage‑based billing; Financial services engineering (banks, insurers, or payment providers) is the ideal background; other regulated‑industry or security engineering depth also counts; Open‑source contributions or a portfolio of deployed agents and eval suites (we would rather see this than a CV)
