Senior Software Engineer (Athena)

Chainguard secures the open source software supply chain by delivering hardened, secure, and production-ready builds. The Senior Software Engineer will build and operate Athena’s enterprise-scale clearing house, developing Go backend systems on GCP, designing agentic workflows, and leading features and subsystems from design through production.

Responsibilities:

• Build and maintain core components of the clearing house in Go on GCP including customer onboarding flows, entitlement logic, and data ingestion pipelines
• Take on ownership of ambiguous problems and specific features or subsystems, driving them from design through production with appropriate testing and observability
• Work closely with staff and principal engineers to implement architectural patterns that scale
• Write backend systems that handle unstructured data inputs from enterprise customers and produce structured, validated outputs
• Design, implement, and operate reliable agentic workflows that automate complex, multi-step tasks across production systems
• Participate in on-call rotation and contribute to incident response and postmortems
• Become a go-to engineer for one or more core subsystems, leading multi-engineer efforts over a multi-month horizon
• Review code, give direct feedback, and raise the team's engineering bar
• Contribute infrastructure-as-code and operational tooling using Terraform and GCP-native tooling

Requirements:

• Solid backend engineering foundation  you've shipped and maintained production systems
• Strong Go engineering skills; GCP and Terraform experience
• You can navigate unstructured data problems  (parsing, validating, deduplicating) with a methodical, analytical approach
• Experience working in a team that prioritizes operational excellence: monitoring, alerting, graceful degradation
• Able to scope and drive features independently with minimal oversight
• Experience with Agentic AI workflows
• Security or infrastructure domain knowledge
• Experience in security vulnerability domain, coordinated disclosure process, or CVE publication
• Experience with customer-facing APIs or workflow systems is a plus
