About the Role
We're looking for a C# SDK Engineer to join our SDK team and help bring official, first-class Supabase support to the .NET and Unity ecosystems. You'll work closely with our existing SDK engineers, the broader product and engineering team, and the C# developer community, helping us design, build, and maintain an SDK that feels native to the stack.
This role is ideal for someone who thrives in async, fast-paced environments and is excited about building developer tools that scale to millions.
What You'll Own
Design and build the C# SDK — own the Supabase C# SDK end-to-end, including Auth, Database, Storage, Functions and Realtime clients, ensuring every surface feels idiomatic to .NET developers
Drive the developer experience — make deliberate API design decisions that are well-typed, consistent, and intuitive for developers coming from the .NET ecosystem
Shape the roadmap — identify gaps, triage feedback, and propose improvements based on real developer needs and Supabase product direction
Engage the community — participate in GitHub discussions, review contributions, and build relationships with .NET and Unity developers using Supabase
Collaborate across the SDK team — contribute to shared patterns, tooling, and standards that raise the quality bar across all supported languages
Write documentation and examples — produce guides, code samples, and reference docs that help developers get started quickly and go deep with confidence
What You Bring
Have 5+ years of experience building production applications in C# and the .NET ecosystem
Have prior experience building SDKs, libraries, or other developer-facing tools, with a strong sense of what makes an API intuitive and idiomatic
Are comfortable working across multiple programming languages and ecosystems — you can read TypeScript, Python, or Go to draw patterns from the broader SDK team
Communicate clearly across both technical and non-technical audiences
Have experience in async or globally distributed teams
Are energized by solving real-world problems for developers
Are comfortable navigating ambiguity and moving quickly
