Software Engineer – Platform / Core Infrastructure

London

4 days a week on site

Up to £110k

We’re working with a London-based fintech that has scaled rapidly in a short space of time. Their platform now processes billions in annual transaction volume, operating across multiple markets and supporting a fast-growing customer base.

With that growth comes complexity - and that’s where this role sits.

The opportunity

This is a role in the Core Infrastructure (Platform) team - the group responsible for how engineering happens across the business.

You won’t be building end-user features. You’ll be building the systems, tooling, and infrastructure that every engineering team relies on to ship safely, quickly, and at scale.

The team treats infrastructure as a product. Internal engineers are the users. Adoption, usability, and reliability matter.

What you’ll actually be doing

• Building a self-service internal platform used across multiple teams
• Reducing friction in the software lifecycle - from local dev → deploy → production
• Improving developer experience (DevEx) by simplifying workflows and abstractions
• Developing cloud-native tooling and platform services
• Contributing to CI/CD pipelines and GitOps-based delivery models
• Designing for scale, reliability, and security by default
• Working directly with engineers to understand bottlenecks and remove them

Tech environment

• Golang
• Kubernetes (production-scale)
• AWS (multi-account environment)
• Terraform / Infrastructure as Code
• CI/CD pipelines + GitOps workflows

What they’re looking for

• Background in Software Engineering, Platform Engineering, DevOps or SRE
• Some experience with Golang
• Experience working in cloud-native environments (AWS or GCP)
• Hands-on with Kubernetes and containerised systems
• Familiarity with Infrastructure as Code (Terraform or similar)
• Experience building or maintaining CI/CD pipelines
• Interest in developer tooling, platform thinking, and DevEx

The reality

This isn’t a pure DevOps support role.

It’s building the platform layer properly - with product thinking, long-term ownership, and a focus on making engineers faster.
