Senior Platform Engineer

We're looking for a Senior Platform Engineer to help us scale the multi-account AWS platforms that now power Lendable products across the UK, US and Mexico, supporting the hundreds of engineers shipping on top of them.

You'll be joining a Platform Engineering team of eight, reporting to our Platform Engineering Manager. This is a senior, hands-on role in a production environment where minutes of downtime translate directly into customer impact. You'll take ownership of key parts of our platform, driving technical direction and making pragmatic trade-offs between reliability, cost, and developer experience. We build with self-service in mind, creating paved roads, abstractions, and guardrails that enable product teams to move fast without needing to understand the underlying complexity.

Your responsibilities will include

• Design and manage core AWS infrastructure via Terraform and Terragrunt

• Build and operate robust Kubernetes, GitOps and observability tooling

• Shape how engineering teams ship to production, progressive rollouts, canary deploys and fast, safe rollbacks

• Bake security into the SDLC, policy-as-code, OIDC-based cloud access, secret scanning and pre-merge controls, working closely with our Security team

• Partner with engineering teams on infrastructure, database and deployment best practices

• Provide and continuously improve CI/CD and developer tooling

• Share an on-call rotation with the team, supported by the observability and tooling you help build

• We make use of AI-assisted tooling (e.g. code generation, debugging, and platform operations). You’re either already comfortable working this way, or excited to adopt it.

Your experience

• Production experience running Kubernetes at scale, not just deploying to it, but operating it.

• Proven ability to improve developer experience and platform adoption across teams

• Deep cloud experience, ideally on AWS.

• Strong infrastructure-as-code skills with Terraform (Terragrunt a bonus).

• Hands-on experience with a modern observability stack including Datadog, Prometheus, Grafana.

• Modern CI/CD experience: GitHub Actions, ArgoCD, Flux.

• Comfort scripting in at least one of the following: TypeScript/Node, Python or Go.

• A solid grounding in Linux, networking, and security fundamentals.

We don't expect every box to be ticked. If most of this sounds like you, we'd like to hear from you.

What success looks like in this role

• Product teams can ship to production independently using self-service platform capabilities, without needing direct support from Platform Engineering

• Platform standards (infrastructure, deployment, security) are widely adopted across teams

• Changes to the platform measurably improve developer experience and delivery speed

• Incidents are reduced over time through better system design, observability, and guardrails

• Infrastructure is scalable, cost-efficient, and secure by default, with clear trade-offs made where needed

Our tech stack

• Cloud & compute: AWS (multi-account, multi-region), EKS with Karpenter and KEDA

• IaC: Terraform, Terragrunt, Helm

• CI/CD & GitOps: GitHub Actions, ArgoCD, Argo Rollouts

• Observability: Datadog, Prometheus, Grafana

• Security: HashiCorp Vault, Kyverno, Checkov, Aikido

• Databases: PostgreSQL and MySQL

• Developer platform: Backstage

• AI tooling: Claude Code, Cursor, Augment

• Tooling we build ourselves: TypeScript
