Senior Product Manager; Athena)

Chainguard is the trusted source for open source. By delivering hardened, secure, and production-ready builds of all the open source software engineers and AI agents rely on, Chainguard helps organizations build faster, stay compliant, and eliminate risk. Our customers include Fortune 500 enterprises and global industry leaders, including Anduril, Canva, Fortinet, Hewlett Packard Enterprise, OpenAI, Snap Inc., and Snowflake. Chainguard is venture-backed by leading investors, including Amplify, IVP, Kleiner Perkins, Lightspeed Venture Partners, Mantis VC, Redpoint Ventures, Sequoia Capital, and Spark Capital.

Chainguard secures the open source supply chain—the infrastructure underneath the majority of software running in production today. This team is building Athena, the system that makes that possible at enterprise scale. Learn more about Athena.

Athena processes vulnerability reports from enterprise customers, validates and deduplicates findings, and routes clean signals to remediation. We are building the clearing house between our customers and Chainguard’s remediation engine.

As Senior Product Manager, you will own the Athena member experience end to end—from vulnerability intake and submission through validation, remediation, and the delivery of patches and advisories. Your scope will span private feeds, the Chainguard Console, documentation, and customer-facing operations. Rather than owning a single feature, you will bring together multiple teams and related product areas to create a cohesive, scalable member experience.

This is a highly cross-functional role for a product leader who understands deeply technical enterprise customers, can create clarity from noisy input, and is comfortable operating independently in a fast-moving security environment.

What you’ll do

• Own the end-to-end Athena member workflow and strategy:
  Define the product strategy, roadmap, and priorities for the member experience, from intake and validation through status visibility, remediation, and how patches and advisories appear in OSV and VEX feeds, private feeds, the registry, console, and documentation.

• Be the primary product voice:
  Represent Athena internally and with customers on scope, capabilities, and direction, and educate customer-facing teams so they can communicate clearly and credibly.

• Turn field input into a prioritized backlog:
  Identify systemic gaps across the member workflow, convert recurring questions, feedback, and feature requests into clear problem statements, and maintain a well-written, prioritized backlog.

• Lead cross-functional delivery and technical tradeoffs:
  Align roadmaps and ownership across Engineering, remediation, Documentation, Customer Success, and other partners; work with Engineering on data validation, workflow routing, entitlements, access controls, and reliability; and partner with remediation on patch delivery, including disclosure readiness, SBOMs and provenance, breaking changes, and capacity tradeoffs.

• Measure, flag risks, and mentor:
  Define and report member-experience metrics (submission volume and coverage, time to patch, status visibility, feed adoption), raise customer, delivery, and business risks early (especially around disclosure cycles), and serve as a trusted partner and mentor to product peers.

What we’re looking for

• 5+ years of product management experience, including ownership of a technical B2B product serving enterprise customers in regulated industries; financial-services experience is strongly preferred. Working fluency in software supply chain security, including CVEs, OSV, VEX, SBOMs, provenance, and vulnerability disclosure.

• Experience leading complex initiatives across multiple engineering and business teams without…
