[Remote] Senior Software Engineer (Guarded OS)

Note: The job is a remote job and is open to candidates in USA. Chainguard is the trusted source for open source, delivering hardened and secure builds of open source software. The Senior Software Engineer will play a key role in developing and maintaining the Elastic Build service and related tooling for Chainguard OS, ensuring systems are reliable, performant, and secure.

Responsibilities

• Operate and develop the Elastic Build service, our Kubernetes + GitHub + Cloud Run pipeline that converts package specifications into real downloadable artifacts, improving reliability, performance, resource usage, and multi-architecture support
• Maintain and improve Melange, our package build tool, with a focus on usability, testing, patch management, and observability. Melange is largely feature-complete; the work here is hardening and instrumentation, not feature addition
• Design and build automation for rebuild and review workflows — keeping a human in the approval chain while removing every step that can be automated. Support shared library transitions using build-time and runtime dependency analysis
• Build monitoring, dashboards, and alerting. Create automated responses to common failure modes so human attention is reserved for novel problems
• Define and deliver a roadmap for build and update services within the OS team
• Document systems thoroughly and reduce single points of knowledge
• Contribute to distro-level package updates and help keep Chainguard OS up-to-date and secure

• Strong programming skills in Go. Comfortable writing production services, ideally including a Kubernetes operator or custom controller
• Hands-on experience operating production services at scale, and has responded to real incidents, restored service, and improved systems to prevent recurrence
• Hands-on experience with Kubernetes, Cloud Run, and cloud-native service design
• Familiarity with GCP services (e.g., BigQuery, IAM, Cloud Logging)
• Experience with Terraform and CI/CD pipelines
• Strong debugging and problem-solving skills across distributed systems
• Able to work independently and communicate clearly in a remote-first environment
• Experience contributing to or maintaining build, packaging, or tooling projects
• Observability and monitoring experience (Grafana, Prometheus, Cloud Logging, etc.)
• Experience with Linux build or packaging systems
• Understanding of dependency management and rebuild automation
• Experience with ARM64 build environments
• Familiarity with BigQuery or Looker Studio for data analysis
