Senior SDK Engineer - C#/.NET & C++ API Design

Autodesk; Novi (MI); On-site; USD 117,000 - 209,000; Full time

Job summary

Autodesk is seeking a Senior Software Engineer to build high-quality SDKs and developer-facing APIs. You will work across C#/.NET and C++, enabling interop and contributing to API design, testing, packaging, and CI/CD across the lifecycle.

You’ll collaborate with product and platform teams, maintain NuGet artifacts, and leverage AI-assisted tools while upholding high engineering standards. A strong foundation in CS is valued, not necessarily a formal degree.

Qualifications

• Strong demonstrated software engineering skills and experience developing production-quality software.
• Experience developing applications, libraries, or SDKs with modern C#/.NET and modern C++.
• Experience across C# and C++ boundaries or with comparable managed/native interoperability.
• Ability to contribute effectively in both C# and C++, with demonstrated willingness to deepen expertise where needed.
• Experience designing and implementing SDKs, libraries, or developer-facing APIs.
• Strong understanding of API design principles and developer experience.
• Experience evolving APIs while considering backward compatibility, versioning, and the impact of changes on downstream consumers.
• Strong experience with automated unit testing and designing software for testability.
• Experience with software build, packaging, dependency management, and continuous integration practices.
• Experience working with source control and collaborative software development workflows.
• Strong technical communication skills and the ability to discuss, explain, challenge, and refine architecture and implementation approaches with other engineers.
• Ability to work independently across unfamiliar areas of a technology stack and a demonstrated willingness to develop new technical expertise.
• Practical experience using modern AI-assisted software development tools such as GitHub Copilot, Claude Code, Cursor, ChatGPT, or comparable technologies.
• Demonstrated ability to use AI-assisted development responsibly, including validating generated code, managing context, maintaining software quality, and recognizing when generated solutions require additional investigation or should not be used.

Responsibilities

• Design, implement, test, document, and maintain production-quality SDKs and reusable software components.
• Develop across modern C#/.NET and modern C++, including communication and interoperability between managed C# and native C++ components.
• Participate actively in the architecture and design of developer-facing APIs, contributing experience and perspective to technical decisions across the team.
• Design APIs that are intuitive, maintainable, and capable of evolving over time while minimizing breaking changes for consumers.
• Consider API lifecycle concerns including compatibility, versioning, deprecation, and migration strategies.
• Collaborate with Autodesk product and platform teams that integrate and depend on the team's SDKs.
• Contribute to technical discussions with partner teams and represent the team's designs, decisions, and work in broader engineering forums when appropriate.
• Develop comprehensive automated unit tests and contribute to broader integration, compatibility, consumer, and performance testing strategies.
• Own software through its complete delivery lifecycle, including build, packaging, CI/CD, artifact publishing, and release.
• Create and maintain NuGet packages and other software artifacts, including package versioning, signing, publishing, and dependency management.
• Reason about complex dependency graphs and compatibility issues across reusable managed and native components.
• Contribute to and maintain automated CI/CD pipelines used to build, test, validate, package, and deliver the team's software.
• Use modern AI-assisted development tools as part of a disciplined engineering workflow, applying appropriate validation and engineering judgment to generated code and solutions.
• Independently investigate unfamiliar technologies and technical problems, develop expertise, and share knowledge with the team.
• Contribute to the growth of other engineers through technical collaboration and, as familiarity with the team and technology grows, informal mentoring.
