Purpose and Overview of Role

This is a hands‑on engineering role within the Platform Engineering team, part of Technology Operations.

Platform Engineering is responsible for building and operating the infrastructure, platforms and developer tooling that enable our engineering and quantitative research teams to deliver software reliably, securely and at scale.

The role will help design, build, automate and operate a hybrid production platform across AWS and on‑premises environments, with a particular focus on the Hashi Corp platform: Nomad, Consul and Vault.

The successful candidate will treat infrastructure as software, promote automation‑first practices and build reusable platform capabilities that improve developer experience, operational resilience and security.

The role requires strong judgement when making platform changes, including understanding architecture, satisfying deployment prerequisites, managing YAML and infrastructure configuration carefully, and assessing impact across the wider platform during maintenance and change activity.

• Own, maintain and evolve the Hashi Corp platform, including Vault, Consul, Nomad and associated integrations.
• Use Terraform to define and manage infrastructure resources, configuration and reusable platform modules.
• Use Ansible to support multi‑stage deployment workflows, configuration management and repeatable operational procedures.
• Build internal tooling, automation and self‑service capabilities that improve developer productivity and reduce operational overhead.
• Support and enhance CI/CD platforms and engineering workflows, including safe promotion of infrastructure and platform changes.
• Improve platform reliability, security, observability, performance and operational excellence.
• Partner with software engineers, quantitative developers, research teams, Tech Ops and security colleagues to deliver secure, scalable and resilient platforms.
