Platform Engineer - London

Gibson Dunn is a leading global law firm, advising clients on significant transactions and disputes. Our exceptional teams craft and deploy creative legal strategies that are meticulously tailored to every matter, however complex or high-stakes. The firm’s work is distinguished by a unique combination of precision and vision.

Based in London, the Platform Engineer will be responsible for building the reusable platforms, tools, and services that improve developer productivity, accelerate delivery, and standardize engineering practices across the firm. The role writes and ships the code behind the firm’s internal developer platform, building and maintaining self-service tooling, infrastructure-as-code modules, pipeline definitions, and automation across CI/CD, cloud, and observability, and participating in the team’s operational and on-call duties.

Working under the guidance of senior engineers, this role delivers reliable, well-tested code and self-service capabilities for development teams while growing toward end-to-end ownership.

The platform supports conventional in-house software alongside AI workloads such as model inference, retrieval, and agent-based systems, all on a shared foundation. This role helps extend the same pipelines and reliability standards to AI workloads, while recognizing where AI demands different primitives such as evaluations, non-deterministic failure handling, token economics, and confidentiality controls.
