Senior Platform Engineer

Senior Platform Engineer | Azure, Terraform, CI/CD | Bank-Grade Cloud Platform Build

• £600–£650 p/d (Outside IR35)
• 5-month initial contract (extensions likely)
• Hybrid: London (2 days/week on-site)

The Role

Join a newly formed Cloud Platform Engineering team building a greenfield Azure platform for a regulated banking venture. You’ll join as a senior individual contributor, taking ownership of the most complex, high-risk platform engineering work across a large Azure estate in a regulated financial services environment.

This is not a people management role — you’ll lead through your code, your technical judgement, and your ability to turn ambitious platform designs into secure, scalable, production-ready infrastructure.

You will:

• Own and deliver the highest-risk, most complex or ambiguous platform work
• Build and enhance Azure landing zones and internal platform services
• Deliver infrastructure-as-code, CI/CD , self-service tooling and observability end-to-end
• Challenge design assumptions with a “show me the code” approach
• Pair with engineers to unblock delivery and lift team-wide engineering standards

Non-Negotiables:

• 8+ years infrastructure engineering in Azure environments
• Terraform expertise at scale: modules, composition, patterns and anti-patterns
• Strong Azure networking, security and governance knowledge
• Experience in regulated environments (FS, healthcare, government, etc.)
• CI/CD and automation experience (Azure DevOps/GitHub Actions, scripting)
• Ability to troubleshoot complex infra, identity, networking and security issues
• TDD/automated testing for infrastructure changes
• Experience mentoring and guiding other engineers

What You’ll Work With:

• Terraform: modular IaC, policy integration, testing and validation
• Azure Core: networking, security, identity, governance, landing zones
• Azure PaaS: App Service, Functions, container platforms (ACA/AKS)
• CI/CD: GitHub Actions or Azure DevOps with full automation
• Observability: logging, metrics, dashboards and alerting
• Incident Response: diagnosing and resolving complex platform issues

Why Join:

• Shape a secure, scalable Azure platform in a regulated financial services environment
• Own complex landing zones and platform capabilities that have organisation-wide impact
• Influence engineering standards, patterns and delivery practices
• Work in a collaborative, Kanban-driven team focused on high-quality delivery
• Lead through hands-on engineering, pairing and code reviews — not hierarchy

If you enjoy solving deep technical problems, shipping high-quality infrastructure, and elevating engineering teams through hands-on expertise, this role will suit you perfectly.
