Senior DevSecOps Engineer | AWS | Kubernetes | Terraform
Hands on cloud engineering role combining platform ownership with practical security at a scaling fintech
Remote | Applicants must already be living in the UK with the correct right to work
Our client builds a HFT data platform used by financial services firms to process and act on time sensitive market information at speed. The business is growing, engineering is scaling, and there is plenty of opportunity to influence how the platform evolves.
We're looking for a Senior DevSecOps Engineer to join a small, experienced engineering team and help build, operate and secure the AWS infrastructure behind a modern financial technology platform.
This isn't a governance or compliance focused security position. It's a hands on engineering role for someone who is equally comfortable working across AWS, Kubernetes, Terraform and CI/CD as they are implementing practical security improvements across cloud infrastructure, containers, pipelines and access controls.
You'll work closely with the existing Platform Engineer and CISO, helping translate security requirements and findings into practical technical solutions whilst taking broad ownership across the platform.
It's a genuinely varied role within a small team. They need someone who can understand a problem, work out what needs doing and implement it, rather than operating within a narrow infrastructure or security silo.

- Writing scripts and tooling in Python, Go or similar to automate infrastructure, operational and security processes
- Working closely with engineering and security to solve problems across traditional team boundaries
