Job Summary

Our team builds and provides Idira Secure Workload Access solution. The team's mission is to solve workload identity and authentication problems our customers face, and to secure workload communication while practicing the highest security standards and providing the best possible user experience. We are seeking a Principal DevOps Engineer to treat the software release lifecycle as a first-class product. In this role, you will move beyond basic automation to architect a resilient, high-velocity delivery ecosystem. By engineering the end-to-end lifecycle for diverse components-including SDKs, Terraform providers, installable software, and Cloud services-you will ensure our deployment pipeline is seamless, scalable, and fortified by the highest security standards. You will also be responsible for maintaining and automating the underlying infrastructure to enable the testing.

Responsibilities

• Design, build and maintain pipelines for testing and shipping our software, involving multiple steps and complex dependencies. We want reliable and robust pipelines that will involve testing in multiple environments and across multiple versions, as well as other steps such as security scanning and code signing.
• Maintain the test infrastructure underlying these pipelines with devops tooling, involving third-party dependencies, test environments with multiple versions of platforms we support, cloud accounts, and more.
• Work with the development team to build a great developer experience, with ad-hoc environments for manual testing, easily debuggable pipelines and more.
• Monitor test pipelines and triage issues, passing off to the developers when it's a real problem. Look for underlying issues, and work with developers to troubleshoot as needed.
• Provide feedback on the product to make it better for our users as well as making it more testable and debuggable for us.
• Continuous Improvement: Analyze pipeline bottlenecks and "flaky" deployment steps, relentlessly optimizing for speed without sacrificing security and reliability.

Qualifications

• Extensive experience with DevOps tooling and automation, including Terraform, Jenkins, AWS, GitOps, and other tools.
• Some experience with programming/scripting.
• Motivated by providing a great developer experience.
• A track record of working in a highly collaborative way.
• Sharp debugging skills, using a methodical approach to isolate issues within a highly complex environment.
• Experience working with monitoring tools such as datadog, knowing both how to build good dashboards, and also ad-hoc techniques to isolate issues.
• Preferably experience with supply chain security practices such as vulnerability scanning and code signing.
