About the Role

We are a fully regulated UK bank powering the accounts and payments offerings of product-led fintechs and platforms. We provide the banking backbone for various industries and are expanding into card issuing, stablecoin infrastructure, and agentic finance. Our culture fosters high-trust, high-autonomy environments, and we operate remotely with asynchronous and flexible work.

Responsibilities

  • Manage the infrastructure the bank runs on, both in the cloud and on our own hardware in third-party data centres.
  • Run FoundationDB clusters and build tooling for hitless upgrades.
  • Manage Kubernetes.
  • Write infrastructure as code in Pulumi and CDK.
  • Run the Bazel build farm.
  • Own the deployment pipeline from CI to production.
  • Ensure operational resilience through replica clusters, multi-region failover, and chaos engineering.
  • Manage security access, CircleCI pipelines, DataDog integration, and cloud spend.
  • Build out self-hosted infrastructure to support a hybrid-cloud setup and remove single-vendor reliance.
  • Improve Kubernetes scaling.
  • Improve the build farm.
  • Build out PKI infrastructure.
  • Plan for a global HTTP routing layer for seamless failover between sites.
  • Own infrastructure architecture decisions.
  • Ensure production reliability of the database, compute, build farm, and deployment pipelines.
  • Provide CI/CD, security access, and monitoring integration for other teams.
  • Manage infrastructure cost and efficiency across AWS and DataDog.

Requirements

  • Solid systems experience, including running container orchestration in production.
  • Experience writing infrastructure as code.
  • Understanding of IP networking sufficient to debug issues.
  • Cloud infrastructure experience, including building and managing production environments.
  • Experience with networking, identity management, and compute at scale.
  • Strong programming fundamentals, writing code to solve problems (TypeScript, Python, Go, or functional languages are acceptable).
  • Comfort with startup environments, including small teams, shifting priorities, and high autonomy.
  • Willingness to learn Clojure.
  • Comfortable picking up new languages and approaches.
  • Ability to read and understand codebases of open-source systems and tools written in diverse languages.
  • Successful completion of background screening, including verification of right to work, criminal record, credit history, social media, and professional reference checks.
