Infrastructure Engineer

📋 Job Overview

We are looking for an Infrastructure Engineer to join our small team of three within the Craft function at Griffin. As a fully regulated UK bank, we power the accounts and payments offerings of product-led fintechs and platforms. Our culture thrives in high-trust, high-autonomy environments, and we remain remote-first since our establishment in 2017.

🏢 About Griffin

Hi, we’re Griffin. We’re a fully regulated UK bank that powers the accounts and payments offerings of product-led fintechs and platforms like Uber, Yonder, Prosper, and Sidekick. By doing the heavy lifting behind the scenes, our customers can focus on what they do best - delivering amazing customer experiences. We’ve grown rapidly since our launch in 2024, and today provide the banking backbone behind products in remittance, payroll, wealth, insurance, proptech, payments, neobanking and more. We’re moving into card issuing, stablecoin infrastructure, and agentic finance next as we continue to support the next generation of product-led companies.

🎯 The Role

Day to day, you'll manage the infrastructure the bank runs on - both in the cloud and on our own hardware in third party data centres. This means running FoundationDB clusters and building tooling for hitless upgrades, managing Kubernetes, writing infrastructure as code in Pulumi and CDK, running the Bazel build farm, and owning the deployment pipeline from CI to production. Operational resilience is a big part of the job: replica clusters, multi-region failover, and chaos engineering to test how systems handle failures. Security access, CircleCI pipelines, DataDog integration, and cloud spend all fall under infrastructure too.

✅ Key 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 and write infrastructure as code in Pulumi and CDK.
• Run the Bazel build farm and own the deployment pipeline from CI to production.
• Ensure operational resilience through replica clusters, multi-region failover, and chaos engineering.
• Handle security access, CircleCI pipelines, DataDog integration, and cloud spend.
• Contribute to building out our self-hosted infrastructure to support a hybrid-cloud setup.
• Improve how Kubernetes scales, the build farm, and our PKI infrastructure.
• Plan and implement a global HTTP routing layer for seamless failover between sites.

📌 Required Qualifications

• Solid systems experience - you've run container orchestration in production, written infrastructure as code, and understand IP networking well enough to debug it when things go wrong.
• Cloud infrastructure experience - you've built and managed production environments, worked with networking, identity management, and compute at scale.
• Programming fundamentals - you write code to solve problems. TypeScript, Python, Go, or functional languages are all fine.

⭐ Desirable Experience

• Experience with FoundationDB, Kubernetes, Bazel, Pulumi, CDK, CircleCI, DataDog, Clojure, and TypeScript.
• Comfort with star
