Senior AWS Platform Engineer

Senior Platform Engineer

London (Hybrid, 2 days per week in the office)

Up to £90,000 + Benefits

We're partnering with a software company building mission critical platforms for financial services, trading firms, and the gambling sector. Regulated, high stakes environments where downtime and security gaps aren't an option.

They're looking for a Senior Platform Engineer who can operate as a technical leader. Not a ticket taker. Someone who can architect cloud native solutions on AWS, set the standard for how the platform is built, and bring genuine site reliability engineering principles into the way the business operates.

You'll be the person engineering teams turn to when they need a platform decision making. That means real ownership of architecture, real influence over direction, and the freedom to fix the things that slow delivery down.

If you enjoy building resilient, well automated infrastructure in environments where compliance actually matters, this one could be a good fit.

What You'll Be Doing

Architect and build secure, scalable AWS infrastructure using Terraform with an Infrastructure as Code first approach

Design, run, and optimise Amazon EKS and containerised workloads across multiple environments

Build and maintain CI/CD pipelines using GitHub Actions to give engineering teams fast, safe, repeatable deployments

Write automation and tooling in Python or Go to remove manual work and reduce operational overhead

Support and optimise Amazon RDS environments for availability, performance, and security

Embed site reliability principles across the platform, including SLIs, SLOs, error budgets, and blameless incident reviews

Build out monitoring, logging, alerting, and observability so problems are spotted before customers feel them

Design solutions that meet the security, audit, and regulatory requirements that come with financial services, trading, and gambling clients

Work closely with software engineering teams to improve developer experience and delivery speed

Lead technical decisions, set standards, and take architectural ownership of the platform

What We're Looking For

Strong background in Platform Engineering, DevOps, Cloud Engineering, or SRE

Deep hands on AWS experience, including networking, IAM, and security

Commercial experience running Kubernetes in production, ideally EKS

Expert level Terraform and Infrastructure as Code

Solid experience building CI/CD pipelines with GitHub Actions

Strong programming ability in Python or Go, beyond basic scripting

Confident with Linux administration, troubleshooting, and performance tuning

Experience with Amazon RDS or similar managed database services

Track record of architecting cloud native platforms in regulated or security sensitive environments

Comfortable leading technical conversations with engineers and stakeholders alike

Why Join?

Work on platforms that power financial services, trading, and gambling businesses at scale

Genuine technical leadership with real architectural ownership

Modern AWS stack with no legacy baggage holding you back

Regulated environments that make the engineering problems more interesting, not more restrictive

A team that values engineering quality over shipping at any cost

Investment in training, certifications, and progression

Don't Tick Every Box?

That's fine.

Nobody has every line on a spec. If you've got strong AWS, Kubernetes, and Terraform experience, plus the ability to think architecturally and lead technically, that's the core of it. The rest can be learned.
