Senior Software Engineer (Athena)

Senior Software Engineer

Chainguard is building the secure software supply chain, the infrastructure underneath the majority of the software running in production today. This team is building Athena, the system that makes that possible at enterprise scale. We're the clearing house that processes vulnerability data from enterprise customers, validates it, and feeds it to the remediation engine. Right now we're transitioning from a fast-moving prototype to a production system that enterprise customers depend on and we need senior engineers who can drive that transition and own significant pieces of it.

What you'll do

• 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
• 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

What we're looking for

• 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 customer-facing APIs or workflow systems is a plus
• Security or infrastructure domain knowledge
