Senior Platform Engineer

About Lendable

Lendable is on a mission to build the world's best technology to help people get credit and save money.We're building one of the world’s leading fintech companies and are off to a strong start:

One of the UK’s newest unicorns with a team of just over 700 people

Among the fastest-growing tech companies in the UK

Profitable since 2017

Backed by top investors including Balderton Capital and Goldman Sachs

Loved by customers with the best reviews in the market (4.9 across 10,000s of reviews on Trustpilot)

So far, we’ve rebuilt the Big Three consumer finance products from scratch: loans, credit cards and car finance. We get money into our customers’ hands in minutes instead of days.

We’re growing fast, and there’s a lot more to do: we’re going after the two biggest Western markets (UK and US) where trillions worth of financial products are held by big banks with dated systems and painful processes.

Join us if you want to

• Take ownership across a broad remit. You are trusted to make decisions that drive a material impact on the direction and success of Lendable from day 1
• Work in small teams of exceptional people, who are relentlessly resourceful to solve problems and find smarter solutions than the status quo
• Build the best technology in-house, using new data sources, machine learning and AI to make machines do the heavy lifting

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
