Join us and help the world’s leading organizations unlock the value of technology and build a more sustainable, more inclusive world.\nJob Description -\nAbout us\nA new AI-native product organisation within Capgemini Financial Services. We build products, not projects: software for insurance claims, payment operations, and health operations, sold to banks, insurers, and health plans. Three 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. Humans own every consequential decision, and in our regulated domains some decisions are human-only by design.\nThe role\nOur engineering model depends on infrastructure most companies treat as an afterthought. AI agents implement most of our code, which means the development loop (environments, builds, CI, the harnesses agents run in) is the engine of the whole organisation's velocity. Every minute an engineer or an agent waits on an environment, a flaky test, or an unreviewable diff is product not shipped. You will own that loop end to end, for people and for agents. The harness is a self-improving system: every failure, transcript, and evaluation verdict is fuel for the next version of the harness and, increasingly, for the models inside it.\nWhat you will own\n Development environments end to end: fast, isolated, reproducible, for human engineers and for agent fleets, including sandboxes, ephemeral environments, and warm starts.\nDeterministic CI and the pre-push validation surface, so failures are caught at the desk, not in the pipeline.\nThe agent harness: the tooling, permissions, retry limits, and orchestration blueprints our coding agents operate within, improved permanently every time an agent fails.\nThe recursive improvement loop: agent transcripts, failure modes, and evaluation verdicts flow back into harness changes and model adaptation datasets automatically, so the system that builds our products improves itself.\nEvaluation-gated merges: the CI integration that makes eval suites a first-class merge gate.\nMeasurement: cold-start times, agent PR merge rates, and review-time economics; you improve what you instrument.\nWhat you will need\nPrior ownership of a development environment, build system, or paved-path workflow used by a multi-team engineering organization\nStrong Python plus container and Kubernetes fluency; comfort operating CI/CD systems at scale\nDirect experience deploying or operating AI coding agents (Claude Code, Cursor, Copilot, or in-house), beyond personal use\nYou follow frontier agentic-systems research (harness design, reinforcement learning from execution feedback, evaluation methods) closely enough to put it into production within the quarter it lands\nA measurement habit: you can show numbers for a developer-experience improvement you shipped\nDaily, hands-on use of AI coding assistants as part of your own development workflow\nWhat sets you apart\n Hermetic build systems (Bazel, Buck, Nix, or similar) or monorepo tooling at scale\nGo or Rust; Git-at-scale experience\nYou have built one-shot or unattended agent pipelines with hard failure caps and human escalation\nYou have turned agent execution traces into training or evaluation datasets, or built reinforcement learning pipelines from execution feedback\nYou have written publicly about developer experience or agent harnesses\nFinancial services engineering exposure (banks, insurers, or payment providers)\nThe reference stack\nThe reference technology stack for this role is our supported paved road: self-hosted LangSmith and Lang Graph Platform as the agent runtime and evaluation plane, model providers behind a swappable gateway seam, PostgreSQL with pgvector plus Click House and S3-compatible object storage as the data platform, Neo4j Enterprise as the semantic knowledge graph, an agent memory plane serving episodic and precedent memory over MCP, MCP-native connectors, OpenTelemetry and Grafana for observability, all on CNCF-conformant Kubernetes with Helm and Argo CD, deployable to any hyperscaler or on-prem. A tool-for-tool match is not expected: analogous experience counts fully. If you have built and operated systems of this shape on comparable components (a different orchestration framework, graph engine, evaluation platform, or serving stack), you have what we are looking for.\nHow we work\nEngineers write specs, harnesses, evals, and guardrails; AI agents execute the implementation loops. Review, not typing, is where engineering judgment goes.\nThree human gates govern everything we ship: spec approval, merge, and release. Regulated code paths (money movement, authentication, cryptography, secrets) are always human-owned.\nSmall and senior by design. No separate QA function, no scrum masters; quality comes.\nSuccess in year one\nFresh environment cold-start is measured in seconds, for humans and agents, and you can prove it\nAgent-written PRs merge at a rising rate with flat or falling human review minutes per feature\nEvery recurring agent failure mode from the last two quarters has a permanent harness fix, and the harness has also lost components that model progress made unnecessary\nThe base compensation range for this role in the posted location is: 150000- 170000\nCapgemini provides compensation range information in accordance with applicable national, state, provincial, and local pay transparency laws.
