> Staff Software Engineer builds and owns secure, reproducible .NET build pipelines, NuGet packaging automation, and developer tools for Chainguard Libraries. Requires 8+ years .NET ecosystem experience, Go proficiency, and DevOps/SRE background in cloud-native environments.
## Job Description
## Responsibilities

- 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.

## Nice to Have

- Open source contributions in the .NET ecosystem (libraries, build tools, packaging, or related infrastructure).
- Experience building and distributing widely used libraries, SDKs, or runtimes.
- Familiarity with software supply chain security: **SLSA**, **SBOMs**, sigstore, provenance, attestations.
- Exposure to Linux distribution and packaging ecosystems or reproducible build systems (e.g., **Alpine**, **Wolfi**, **Debian**, **Bazel**, **Nix**).

**Base Salary Range**: $205,000—$231,000 USD
