About The Position

The One Policy Engine is a unified policy platform for multi-cloud environments that keeps Infrastructure‑as‑Code (IaC) compliant from code to cloud. We apply policy enforcement early and consistently across the SDLC so security and compliance are built in from the start. By integrating with platforms like Wiz CNAPP, we extend coverage beyond IaC to continuously assess cloud security posture. This integration helps identify misconfigurations, understand real runtime risk, and prioritize remediation—preventing issues before they reach production. We are seeking a Senior Senior Platform Engineer with deep expertise in Python, cloud-native application development, and hands-on experience with Azure, AWS and DevSecOps. The ideal candidate is a versatile engineer who can design scalable APIs, build secure backend systems, develop modern frontend interfaces, and deploy resilient cloud-enabled solutions across hybrid environments. You will play a key role in integrating AI-powered tools into development workflows, driving automation, and improving developer productivity. A strong background with the Wiz Platform is critical, as this role involves deeply integrating Wiz’s CNAPP capabilities into data‑intensive systems to deliver scalable, reliable, and high‑performance cloud security solutions. You will work closely with engineering and security teams to leverage Wiz insights, automate policy enforcement, and ensure secure-by-design cloud deployments. This role also requires strong DevSecOps skills, including experience with CI/CD pipelines, infrastructure as code (IaC) using Terraform, and containerization technologies like Docker and Kubernetes. You’ll help streamline deployment processes, improve system observability, and ensure high availability across cloud platforms.
