Senior Software Engineer, .NET

📋 Description

• Take ownership of the architecture and strategic direction for the .NET ecosystem infrastructure, facilitating secure and reproducible workflows for building, testing, and distributing .NET libraries and SDKs.

• Design and oversee automation processes for creating, updating, validating, and publishing .NET artifacts (NuGet packages), incorporating vulnerability scanning, remediation, SBOMs, and provenance.

• Develop internal developer tools (MSBuild tasks/targets, NuGet tooling, CLIs, code generators) that enhance the building and maintenance of .NET packages on a large scale.

• Integrate extensively with MSBuild, NuGet, and artifact repositories to address complex dependency and version-resolution challenges in vast codebases and mono-repos.

• Work in collaboration with product and engineering leadership to influence the roadmap for .NET libraries and achieve significant business objectives for Chainguard Libraries.

• Guide and support fellow engineers through design evaluations, documentation, and practical debugging of build and infrastructure problems.

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

⛳️ Requirements

• Over 5 years of experience in the .NET ecosystem (C# or similar) focusing on build systems, packaging, or developer tooling, preferably within platform/infrastructure or ecosystem teams.

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

• Extensive knowledge of MSBuild and NuGet for building and packaging libraries, including handling multi-project/solution builds, dependency graphs, and publishing to registries.

• Strong experience orchestrating large codebases or mono-repos, with a proven track record of resolving dependency and build failures in production settings.

• Expertise in Go for developing build orchestration tools, CLIs, and automation — the primary programming language used by the team for pipeline and glue code.

• Familiarity with Terraform for managing infrastructure as code.

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

• Experience in cloud-native environments, including containers (Docker/OCI, Kubernetes), public clouds (GCP, AWS, or Azure), and modern CI/CD systems (e.g., GitHub Actions, Argo, Tekton, or similar).

• Background in DevOps, SRE, or platform engineering — expertise at the crossroads of build systems and production reliability is essential.

• Exceptional communication skills in a remote and distributed environment. Comfortable collaborating across product, infrastructure, and security, and mentoring senior-level peers.

• A senior-level mindset focused on ownership: you set the direction, take responsibility for crucial outcomes, and excel in a pioneering, high-impact area where engineers contribute to the roadmap.

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