Job Description

Senior Platform EngineerYou probably don't need another Platform Engineering job.
n If you're already running AWS at scale, building Terraform modules and getting pulled into the difficult production incidents, moving somewhere else to do more of the same is not much of a reason to leave.
n This role is different because there is still meaningful platform engineering left to do.
n You'll join a dedicated product engineering environment with the scale, investment and technical standards of a large global organisation, without disappearing into a huge infrastructure function where every decision has already been made.

n

What you'll actually own

n

n
- Multi-region AWS across Lambda, Aurora RDS, VPC, ALB, Route53, IAM and KMS
n
- Reusable Terraform/Terragrunt modules used across customer environments
n
- Reliability engineering against a 99.98% SLO
n
- Observability, incident response and production health
n
- Secure cloud networking, including Transit Gateway and Network Firewall
n
- CI/CD across GitHub Actions and Bitbucket Pipelines
n
- Puppet, Hiera and configuration management at scale
n

n

The expectation is not that you simply operate what already exists.
n You'll lead ambiguous infrastructure problems, improve the standards other teams build against and help decide what the next version of the platform should look like.

n

This is platform engineering, not ticket ops

n

The goal is to make developers faster without making production less safe.
n That means building repeatable infrastructure, better deployment paths,



stronger guardrails and tooling that removes manual work rather than creating another queue for engineers to wait in.
n When something foundational needs to change, you'll be one of the people deciding how it should work.

n

There's also room to push into AI-assisted engineering

n

The team is already exploring Claude, GitHub Copilot and agent-based workflows for platform and DevOps engineering.
n That includes custom instructions, tool-calling schemas and autonomous tooling, rather than simply handing engineers another chat interface.

n

Who this suits

n

You're likely already a Senior Platform, DevOps, Cloud or SRE Engineer.
n You know AWS deeply, have built reusable infrastructure rather than just consumed it, and can move comfortably across Linux, networking, CI/CD, security, Python or Bash and production troubleshooting.
n You're also the sort of engineer people involve when a problem crosses multiple systems and there isn't an obvious answer.

n

Why consider leaving a good job?

n

Because mature platform roles can eventually become maintenance jobs.
n The architecture is decided. The hard problems have been solved. Your job becomes keeping everything moving.
n This one still has important platform decisions left to make.
n You'll get enough scale and complexity to make the engineering engaging, while still having enough influence to change how the platform is built.
n If you're already doing this kind of work somewhere else and weren't planning on moving, that's exactly who we'd like to speak to.
