Senior Data Platform Engineer (Azure | Terraform Expert)
Location: Remote / London Office if preferred
Type: Contract £750 a day (Inside IR35) - Initial 3 month
About the Role
We are seeking a Senior Data Platform Engineer with deep, hands-on Terraform expertise to design and build enterprise-grade Azure infrastructure using Infrastructure as Code as a core discipline.
This role is not a generalist cloud engineering position — it requires someone who can lead Terraform design, create highly reusable modules, manage complex state and environments, and embed security, governance, and observability directly into code. You will be a key technical authority for Terraform across our Azure Data and AI platforms.
What You’ll Be Doing
In this role, you will:
* Own and lead Terraform-based infrastructure design for Azure, ensuring scalability, security, and compliance by default.
* Develop and maintain advanced Terraform modules, standards, and patterns used across multiple teams and environments.
* Automate Azure platform deployments using Terraform, including:
* Azure Data Factory
* Synapse Analytics
* Data Lake & Storage
* Key Vault
* Azure networking and AI/ML services
* Implement and manage Terraform state, backends, workspaces, and strategies for drift detection and remediation.
* Build and maintain CI/CD pipelines (Azure DevOps, GitHub Actions) with Terraform plan/apply workflows, approvals, and policy enforcement.
* Embed observability (monitoring, logging, alerting) directly into infrastructure code.
* Design and implement secure-by-design architectures, including:
* Private Endpoints and private networking
* Managed identities and Key Vault integration
* Application Gateways and network security controls
* Act as a Terraform subject-matter expert, supporting and mentoring engineers and influencing platform standards.
* Work closely with data engineers, architects, and stakeholders to enable reliable Azure data and AI platforms.
What We’re Looking For
Essential Experience (Must-Have):
* 5+ years in Platform or Cloud Engineering, with a strong focus on Azure.
* Expert-level Terraform experience, including:
* Advanced HCL usage and module authoring
* Remote state management and backends
* Environment and workspace strategy
* Lifecycle management and dependency orchestration
* Handling large, multi-environment Terraform estates
* Proven experience deploying Azure Data Platform services using Terraform:
* Azure Data Factory
* Data Lake / Storage
* Synapse Analytics
* AI / ML services
* Strong experience building Terraform-driven CI/CD pipelines using Azure DevOps, GitHub Actions, or similar.
* Proficiency in PowerShell, Bash, or Python for automation and tooling.
* Deep understanding of Azure networking, IAM, and security, including private endpoints and app gateways.
* Experience implementing governance, security controls, and observability through code.
* Strong communication skills and confidence operating in a senior, stakeholder-facing role.
Desirable Certifications
* HashiCorp Terraform Associate (004) or Terraform Professional
* AZ-400 (Azure DevOps Engineer)
* Azure certifications such as:
* Azure Solutions Architect
* Azure Administrator
