ABOUT SUPABASE
Supabase is the Postgres development platform, built by developers for developers. We provide a complete backend solution including Database, Auth, Storage, Edge Functions, Realtime, and Vector Search. All services are deeply integrated and designed for growth.
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
WHAT WE OFFER
- Fully Remote
We hire globally. We believe you can do your best work from anywhere. There are no Supabase offices, but we provide a WeWork membership or co-working allowance you can use anywhere in the world.
- ESOP
Every team member receives ESOP (equity ownership) in the company. We want everyone to share in the upside of what we’re building together.
- Tech Allowance
Use this budget to set up your ideal work environment—laptop, monitor, headphones, or whatever helps you do your best work.
