## About the Role
The Platform Engineering team at builds and operates the firms engineering platform which spans cloud infrastructure CI/CD observability on-call and our internal developer portal. We provide the secure automated foundations upon which the firms regulated services run.

We are seeking a Platform Engineer to help scale this platform through standardized automated and compliant patterns. This role will accelerate delivery for our development teams while raising operational resilience across the entire estate.

Our team is cross-skilled by design; rather than narrow specialization we encourage every engineer to work across the platform fostering broader coverage resilience and shared ownership.

## Key Responsibilities
- Take ownership of larger moderately complex platform projects setting objectives and delivering against project goals with a direct impact on team results.
- Design implement and maintain scalable cloud infrastructure patterns and reusable Terraform modules across Azure AWS and OCI with a primary focus on Azure.
- Develop and maintain Infrastructure as Code (IaC) libraries to ensure consistent compliant and repeatable environments across all cloud providers.
- Build and support CI/CD and deployment automation using GitHub Actions Octopus Deploy and ArgoCD as well as configuration management using Ansible and Octopus Deploy.
- Support and enable development delivery teams by provisioning autonomous environments and reducing deployment friction while maintaining guardrails and separation of duties.
- Provide operational support for containerized and micro-service workloads on Azure Kubernetes Service (AKS) maintaining high availability and reliability.
- Manage core infrastructure lifecycle tasks including vulnerability remediation and patching upgrades scaling and decommissioning across Windows and Linux estates.
- Drive the adoption of cloud governance policies security standards and architectural best practices and help maintain continuous compliance evidence against the firms obligations (SOC 2 ISO 27001 GDPR DORA).
- Contribute to observability and monitoring across the estate and to incident response and on-call including troubleshooting and root cause analysis that drives systemic improvement.
- Support disaster recovery testing to validate recovery plans and ensure rapid reliable restoration of services.
- Identify and recommend improvements to systems processes and infrastructure patterns to enhance operational resilience performance and cost efficiency.
- Explain and advocate technical approaches to development delivery teams and colleagues across IT influencing platform practices and standards at an operational level.
- Provide guidance code review and support to junior engineers helping them develop across the platform.
- Document infrastructure blueprints standards and standard operating procedures in Confluence and our internal Platform Portal to enable self-service.
- Participate in the on-call rota to support critical infrastructure services.
