Senior Software Engineer (Customer Platform)

Chainguard is the trusted source for open source, delivering hardened, secure, and production-ready builds of open source software. The company is seeking a Senior Software Engineer to design and build customer-facing backend services and public APIs for its platform, owning features end-to-end and collaborating with Product and Experience teams to deliver reliable solutions across multiple product lines.

Responsibilities:

• Design, build, and evolve customer-facing backend services and public APIs by understanding how different Chainguard products and customer segments use shared platform capabilities, and ensuring APIs and services work well for all of them
• Own features end-to-end: from design through implementation, rollout, and iteration, in close partnership with Product Management and the Experience (front-end) team
• Create technical design documents and drive your own design plans with clarity and confidence
• 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.”

Requirements:

• Strong backend engineering experience 5+ years of experience building production services and APIs in a modern cloud environment
• Proficiency with Go (Golang) or strong readiness to ramp quickly — we write everything in Go and expect you to get there fast
• Experience designing, implementing, and evolving public APIs that are consumed externally and internally across multiple products or services. You can talk about topics like versioning, backwards compatibility, auth, and usability from real-world experience
• Familiarity with microservices and cloud-native architectures, including containers and Kubernetes, and how to build services that are observable and resilient in production
• Excellent communication and collaboration skills, including the ability to work with PMs, designers, and engineers across multiple product lines
• A genuine interest in a high-paced, high-intensity, “ship it” culture where you're self-directed, comfortable with ambiguity, and working with people who will challenge you to grow as a developer
• Prior experience building platform or shared services that span multiple products or customer experiences
• Experience in the cloud-native, containers, or security ecosystem, or with tools in the broader CNCF space
• Meaningful open source contributions, especially as a maintainer or regular contributor in relevant projects
