• Own and continuously improve our CI/CD pipelines on GitLab and GitHub Actions - building reproducible, secure, and fully automated build, test, scan, and deploy workflows for containerized .NET services.
• Write clean, testable, well-covered code, conduct peer code reviews, and apply secure-by-default best practices across the PKI landscape.
• Write technical software documentation, design decisions, and operational runbooks to drive ongoing engineering excellence.
• Contribute to building a strong, collaborative, and agile engineering culture.

• Proven experience as a C#/.NET developer with strong knowledge of ASP.NET Core.
• Deep experience in asynchronous programming, high-performance API design, and microservices architecture.
• Hands-on experience with AWS services (EKS/Kubernetes, KMS, EC2, IAM) and container deployment.
• Experience building secure authentication and PKI solutions is highly desirable.
• Familiarity with CI/CD tools such as GitLab and GitHub Actions.
• Strong coding standards, test-driven development, and secure-by-default mindset.
