Secure the Future of Cloud Development — One Policy at a Time
Are you a hands-on DevSecOps engineer with a passion for embedding security into the development lifecycle? Do you thrive in high-impact environments where your code shapes how cloud platforms are governed?
Join one of Europe’s top DevOps consultancies — a digital transformation leader trusted by major enterprises across the public and private sector. We're looking for a Terraform Policy Developer with Sentinel experience to help design and implement the next generation of cloud controls for a flagship client.
? The Mission
You’ll play a critical role in developing security policies as code, enabling safe, scalable, and developer-friendly adoption of public cloud infrastructure. This is your chance to help a major organisation “shift security left” — catching misconfigurations and vulnerabilities before they go live.
What You'll Do
Develop 20 new Sentinel policies aligned with AWS best practices and existing Terraform control rules
? Use an existing automated testing framework to validate policy behaviour and fail scenarios
?️ Demo and hand over policies to internal platform teams and customers
? Write clear and practical developer and customer documentation
? Showcase policy capabilities across public cloud teams
? Lead hands-on sessions with users to drive adoption and gather feedback
? Contribute to broader cloud control strategy and parity between Terraform and Sentinel frameworks
Tech Stack & Environment
Terraform (HCL) – infrastructure as code
Sentinel – policy as code (Terraform Cloud/Enterprise)
Python – scripting and automation
GitLab – CI/CD pipelines and source control
AWS – primary cloud provider (Azure coming soon)
Security Frameworks – AWS Foundational Best Practices
Who You Are
An experienced DevSecOps or Platform Engineer with a strong grasp of cloud security automation
You’ve written and deployed Sentinel policies and understand how to enforce security guardrails at scale
Strong working knowledge of Terraform, GitLab, and cloud-native architecture (AWS preferred)
Able to demo, document, and explain your work to engineers, security teams, and stakeholders
Autonomous, collaborative, and comfortable with fast-moving environments
Bonus Points For
Experience with AWS Security Lake
Familiarity with multi-cloud environments
Understanding of Cactus (internal Terraform module library)
Previous experience in public sector or regulated industries
Why Join Us?
? Work with a visionary public cloud platform team on a mission to automate and scale security
? Collaborate with a tight-knit group of high-calibre engineers solving real-world challenges
? Own policy development from discovery to release
? Be part of building a developer-friendly security framework
? Long-term potential and pipeline of exciting cloud transformation projects
