Job description

Chainguard is building the most trusted source for open source software. Every artifact Chainguard distributes is evaluated by our scanner before it reaches a customer. It determines whether a package, container, or AI agent skill is safe to use and sits between our customers and compromised software

What began as a high-leverage internal system has become a core platform powering Chainguard Libraries, Containers, Agent Skills, and future products. We’re hiring a Staff Software Engineer to lead the engineering of that platform

You’ll own its architecture, scale, and reliability. You’ll partner closely with Product Security to turn threat research into detections that run accurately and fast on every artifact we distribute, and with Product to define how customers experience a verdict

This is a backend and production-infrastructure role in a security domain, not a security research role. Product Security develops what the scanner looks for; you build and run the machinery that makes those detections fast, accurate, and dependable across every artifact we distribute

Detection Quality:

• Build the measurement behind coverage and precision: the pipelines, metrics, and dashboards the product is steered by
• Engineer the feedback loop between Engineering and Product Security so a detection change can be evaluated and shipped in hours, not days
• Build the systems for reviewing, escalating, and correcting detections quickly, including bulk correction at ecosystem scale

Scanner Platform:

• Own the architecture of Chainguard’s shared malware scanning platform: scan orchestration, verdict storage, and the APIs every consuming product depends on
• Scale the scanner beyond Libraries to Containers, Agent Skills, and future artifact types
• Make the tradeoffs between detection quality, performance, and extensibility concrete in throughput, latency, and cost

Threat Detection:

• Build and scale the analysis itself: deterministic static analysis alongside AI-assisted reasoning over artifact contents
• Partner with Product Security to take emerging-threat detections from research prototype to production, running on every new release across every ecosystem we cover

Customer Experience:

• Build the APIs and services behind how customers investigate, enforce, and appeal scanner findings
• Build the backend for policy management and enterprise-scale operations

Production Ownership:

• Operate the scanner as a system in the critical path of every customer install: alerting, queue health, verdict-before-serve guarantees, and incident response

Benefits

• Equity/stock options
• Unlimited PTO
• Remote work with flexible coworking and team meetup opportunities
• Home office and internet stipend
• 100% health/dental/vision insurance coverage for you and your family
