About the Role:

We are looking for a skilled Full Stack Developer to join our dedicated Cloud Security Department.

Our team has built a custom service around Wiz, our primary Cloud Native Application Protection Platform (CNAPP) tool. We need you to take ownership, maintaining the existing codebase while developing new features that help secure our massive cloud footprint across multiple cloud providers.

This is a unique opportunity for a developer who wants to pivot into the high-demand field of Cloud Security while keeping their coding skills sharp. You will bridge the gap between application development and operational security.

Key Responsibilities

• Platform Development: Maintain and evolve our internal security portal using .NET (C#) for the backend and Angular for the frontend.
• Wiz Integration: Develop and optimize the service layer that interacts with the Wiz.
• Automation & Scripting: Write efficient scripts (PowerShell, Bash, or Python).
• Infrastructure as Code: Manage the infrastructure for our tools using Terraform/OpenTofu/Cloudformation.
• DevSecOps Implementation: Build and maintain CI/CD pipelines to ensure our tooling is deployed securely and efficiently.
• Operational Excellence: Participate in a 24/7 on-call rotation (1 week per rotation) to ensure high availability of the security services we provide to the organization.

Who You Are

You are a problem solver with a "builder" mindset. You have at least 3 years of experience in software development and have touched the cloud enough to understand the basics of how it works. You aren't afraid of the command line, and you communicate clearly in English.

Required Qualifications

• Full Stack Proficiency: Solid experience with C# (.NET Core/Framework) and modern frontend frameworks, specifically Angular.
• Cloud Experience: Hands-on experience with at least one major cloud provider (AWS, Azure, or GCP).
• Infrastructure as Code: Proficiency with Terraform/OpenTofu/Cloudformation.
• Scripting: Strong scripting capabilities for automation tasks.
• CI/CD: Experience building pipelines (Azure DevOps, GitHub Actions, Gitlab CICD or Jenkins).
• Language: Fluent in English (Written and Verbal) is mandatory.

Nice-to-Haves (The "Cherry on Top")

• Experience with Wiz or other CSPM tools (Prisma, Orca, etc.).
• Background in containerization (Docker/Kubernetes).
• Knowledge of OPA (Open Policy Agent) or security compliance standards.

Why Join Us?

• High Impact: Your code will directly contribute to the security posture of a major global organization.
• Tech Stack: Work with a modern stack including C#, Angular, and Terraform in a multi-cloud environment.
• Skill Growth: This is a perfect gateway into the booming Cyber Security industry. You will learn DevSecOps best practices and advanced cloud security concepts.
• Compensation: Competitive salary and benefits package.

What do we offer?

• An environment where everyone can bring their whole self to work and feel a sense of belonging.
• A workplace that values curiosity and guarantees continuous learning, with development opportunities for both personal and professional growth.
• Share matching programs to become a shareholder of Siemens AG.
• A wide range of flexible benefits for you and your family to enjoy. Click here if you want to learn more
