Staff Software Engineer Customer Platform

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.

The role, in a nutshell:

Chainguard secures the software supply chain — and Customer Platform is how every customer, partner, and internal product line actually connects to it. This team owns the APIs, entitlements, policies, and platform primitives that enable everything else. It's the first thing a customer touches and the integration layer every internal team depends on. We're looking for a Staff Software Engineer who owns hard problems end to end, moves without hand-holding, and can be the technical anchor for a team that touches every corner of the company.

What you'll do:

• Own features end-to-end: from design through implementation, rollout, and iteration, in close partnership with Product Management and the partner Chainguard teams.
• Design, build, and evolve the backend systems (Go, REST/gRPC APIs) that power Chainguard's entitlement, policy, and customer onboarding services
• Serve as the primary technical interface between Customer Platform and other Chainguard engineering teams (Containers, Libraries, OS packages) — understanding their requirements and building integration paths
• Extend Chainguard's agentic AI foundation into customer-facing product experiences
• Provide technical leadership and mentorship to senior and mid-level engineers; help the team break down ambiguity and build toward clear outcomes
• Contribute to a product-driven roadmap with real deadlines and clear outcomes, helping the team prioritize tradeoffs and ship iteratively rather than waiting for "perfect”

What we're looking for:

• Production Go experience is a must. At the staff level, the expectation is deep, idiomatic Go, not "willing to learn"
• Strong ownership of API design and backend systems at scale; you've shipped and operated them in production
• Experience working across multiple engineering teams to align on technical standards, integration patterns, and shared infrastructure
• Comfort operating in ambiguity you come with a diagnosis, a recommendation, and a path forward, not just a problem statement
• Demonstrated ability to mentor engineers and provide technical guidance without needing a management title to do it
• Familiarity with cloud-native environments (Kubernetes, cloud provider APIs) is a stro
