Senior Cloud / DevOps Engineer

Own the Cloud Platform: Design, build and operate our multi-account AWS environments, with Terraform as the backbone for every change, from modules to drift detection to plan-and-review.

Build the Paved Road: Own CI/CD in GitHub Actions and build boilerplates for .NET, Go and Python so teams can ship standardised, production-ready environments with minimal friction.

Engineer Security In: Apply least-privilege IAM, secrets management, network controls and CSPM tooling like Wiz, and embed scanning and policy-as-code directly into pipelines.

Automate Compliance: Build continuous evidence and controls against SOC 2, ISO 27001 and the AWS Well-Architected Framework, so audit readiness is always on, not a scramble.

Own Observability and Reliability: Run the CloudWatch stack, define SLOs, lead incident response and post-incident reviews, and keep runbooks sharp enough for another engineer to follow.

Lead Without the Title: Set platform standards, review infrastructure and pipeline changes from other engineers, mentor the team on cloud and security practice and help shape the roadmap.

Partner Across the Business: Work closely with Infrastructure and Security, Product Engineering squads and Trading Platform Operations to keep the estate secure, resilient and easy to build on.

Significant hands-on experience designing, building and operating production AWS workloads, including multi-account setups, VPC networking, IAM, EC2, Lambda, Fargate, RDS and CloudWatch.

Expert-level Terraform, including authoring reusable modules, managing remote state and refactoring live infrastructure without downtime.

Strong GitHub Actions experience across application and infrastructure pipelines, with secure credential handling.

A genuine software engineering background in at least one general-purpose language (Python, Go, TypeScript or C#), with tests, code review and release discipline as habit.

Demonstrable cloud security engineering, including least-privilege IAM, RBAC, SSO, MFA, secrets management and remediation using CSPM tooling such as Wiz.

Experience automating compliance evidence against ISO 27001, SOC 2 and the AWS Well-Architected Framework
