Staff Software Engineer, .NET

This is a fully remote position, open to applicants in United States.

📋 Description

• Take charge of the architecture and strategic direction for the .NET ecosystem infrastructure, facilitating secure and reproducible build, test, and distribution workflows for .NET libraries and SDKs.

• Develop and sustain automation processes for building, updating, validating, and publishing .NET artifacts (NuGet packages), which includes vulnerability scanning, remediation, SBOMs, and provenance.

• Create internal developer tools (such as dotnet build and MSBuild tasks/targets, NuGet tooling, CLIs, and code generators) that enhance our ability to build and maintain .NET packages at scale.

• Engage deeply with dotnet projects, NuGet, and artifact repositories, addressing complex dependency and version-resolution challenges in large codebases and mono-repositories.

• Work in partnership with product and engineering leadership to define the roadmap for .NET libraries and achieve significant business results for Chainguard Libraries.

• Provide mentorship and support to other engineers through design reviews, documentation, and hands-on troubleshooting of build and infrastructure challenges.

• Collaborate with Platform, Delivery, Sustaining, and Security teams to ensure that .NET pipelines and services fulfill reliability and security requirements.

⛳️ Requirements

• Over 8 years of experience in the .NET ecosystem (C# or similar) focusing on build systems, packaging, or developer tooling, preferably within platform/infra or ecosystem teams.

• Demonstrated experience in developing and managing MSBuild extensions, NuGet tooling, CI/CD automation, or internal frameworks/tools for .NET libraries or services.

• In-depth knowledge of building, publishing, and consuming within the .NET ecosystem (including multi-project/solution builds, dependency graphs, and publishing to registries).

• Strong expertise in managing large codebases or mono-repositories and resolving dependency and build failures in production settings.

• Proficient in Go for build orchestration tools, CLIs, and automation, which is the team’s primary language for pipeline and glue code.

• Experience using Terraform for infrastructure management as code.

• Proven ability to troubleshoot toolchain, compiler, and packaging issues at scale and drive them to resolution.

• Familiarity with cloud-native environments: containers (Docker/OCI, Kubernetes), public cloud platforms (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 intersecting build systems and production reliability is a core expectation.

• Strong communication skills in a remote, distributed environment. Comfortable collaborating across product, infrastructure, and security domains while mentoring senior peers.

• A staff-level ownership mentality: you set the direction, take responsibility for critical outcomes, and excel in an early-stage, high-impact environment where engineers shape the roadmap.

• A systems thinking approach: capable of directing, reviewing, and validating software regardless of its production method — including AI-assisted workflows — and owning outcomes from start to finish.
