About The Position

As a Senior Engineer within Platform Engineering, you will lead the design, build, and evolution of our Internal Developer Platform (IDP), enabling consistent, secure, and scalable software delivery across the enterprise. This role combines DevOps engineering, platform architecture, and developer experience enablement, with a strong focus on CI/CD transformation (Azure DevOps to GitHub), platform tooling, and data platform integration (Snowflake, Databricks). You will act as a subject matter expert (SME) across DevOps tooling, automation, and platform reliability—driving best practices, standardisation, and self‑service capabilities for engineering teams.

Strong knowledge of containerisation and cloud-native technologies (Docker, Kubernetes)
Experience with observability and monitoring frameworks (e.g., Azure Monitor, Prometheus, Grafana) and understanding of SRE practices (SLIs/SLOs, reliability engineering)
Strong scripting/programming skills (Python, PowerShell, Bash) and automation mindset
Good understanding of security, networking, RBAC, and Zero Trust principles in cloud and DevOps environments
Exposure to AI-enabled developer tooling (e.g., GitHub Copilot, intelligent automation) and improving developer experience
Experience operating in regulated, enterprise-scale environments with strong focus on governance, auditability, and compliance
Strong communication, collaboration, and stakeholder management skills, with ability to act as a hands-on SME and technical leader
