Staff Software Engineer,.NET

Job Description:

• Own architecture and direction for .NET ecosystem infrastructure, enabling secure, reproducible build, test, and distribution workflows for .NET libraries and SDKs.
• Design and maintain automation for building, updating, validating, and publishing .NET artifacts (NuGet packages), including vulnerability scanning, remediation, SBOMs, and provenance.
• Build internal developer tools (dotnet build and MSBuild tasks/targets, NuGet tooling, CLIs, code generators) that improve how we build and maintain .NET packages at scale.
• Integrate deeply with dotnet projects, NuGet, and artifact repositories, solving complex dependency and version-resolution issues in large codebases and mono-repos.
• Collaborate with product and engineering leadership to shape the .NET libraries roadmap and deliver on key business outcomes for Chainguard Libraries.
• Mentor and unblock other engineers through design reviews, documentation, and hands-on debugging of build and infrastructure issues.
• Partner with Platform, Delivery, Sustaining, and Security to ensure .NET pipelines and services meet reliability and security expectations.

Requirements:

• 8+ years working in the .NET ecosystem (C# or similar) on build systems, packaging, or developer tooling, ideally on platform/infra or ecosystem teams.
• Proven experience building and owning MSBuild extensions, NuGet tooling, CI/CD automation, or internal frameworks/tools for .NET libraries or services.
• Deep familiarity with building, publishing and consuming in the .NET ecosystem (multi-project/solution builds, dependency graphs, publishing to registries).
• Strong background in orchestrating large codebases or mono-repos and fixing dependency and build failures in production environments.
• Proficiency in Go for build orchestration tooling, CLIs, and automation — the team's primary language for pipeline and glue code.
• Experience with Terraform for managing infrastructure as code.
• Demonstrated ability to debug toolchain, compiler, and packaging issues at scale and drive them to resolution.
• Experience with cloud-native environments: containers (Docker/OCI, Kubernetes), public cloud (GCP, AWS, or Azure), and modern CI/CD systems (e.g., GitHub Actions, Argo, Tekton, or similar).
• Background in DevOps, SRE, or platform engineering — experience at the intersection of build systems and production reliability is a core expectation, not a nice-to-have.
• Excellent communication in a remote, distributed setup. Comfortable working across product, infra, and security, and mentoring peers at senior levels.
• A staff-level ownership mindset: you define direction, own critical outcomes, and thrive in an early, high-impact area where engineers help set the roadmap.
• Systems thinking mindset: comfortable directing, reviewing, and validating software regardless of how it's produced — including AI-assisted workflows — and owning outcomes end-to-end.

Benefits:

• Flexible & Remote-First Culture: Work remotely with team meetup opportunities, bi-annual destination summits, and a monthly stipend for coworking spaces, phone and internet costs.
• Our Approach to Equity: Receive stock options upon hire and promotion. Plus, you can participate in secondary offerings and have 10 years to exercise your options (yes, you read that correctly: 10 years!).
• 100% Covered Health Insurance: We cover 100% of your health, vision and dental insurance premiums for you and your dependents. Nothing comes out of your paycheck.
• ∞ Flexible Time Off: Take the time you need – to do our best work, we need to recharge and reset.
• 18 Weeks Paid Parental Leave: We offer 18 weeks for birthing parents and 12 weeks for non-birthing parents, with the option to use it all at once or throughout your child's first year.
