About this role
This is a hands-on engineering role within the Platform Engineering team, which forms 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 contribute to the design, build, automation and operation of a hybrid production platform across AWS and on-premises environments, with a particular focus on the HashiCorp platform, including 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 the architecture, ensuring deployment prerequisites are met, carefully managing YAML and infrastructure configuration, and assessing the impact of maintenance and change activity across the wider platform. Design, build, automate and operate the production platform across AWS and on-premises infrastructure. Own, maintain and evolve the HashiCorp 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 the safe promotion of infrastructure and platform changes. Improve platform reliability, security, observability, performance and operational excellence. Partner with software engineers, quantitative developers, research teams, Technology Operations and security colleagues to deliver secure, scalable and resilient platforms.
