SDK Engineer

Role Description

We're looking for a JS SDK Engineer to join the SDK team and own a core part of how developers talk to Supabase from JavaScript and TypeScript. Our JS/TS SDKs are the front door to the platform, including:

• Database queries
• Auth
• Storage
• Realtime subscriptions
• Edge functions

This is a library-authoring role, and the work happens in the open: public repos, public issue trackers, and API decisions whose consequences are permanent. The type system here is a design surface rather than a formality. If you get satisfaction from:

• An inference that Just Works
• A migration guide that saves people an afternoon
• An issue tracker that isn't a graveyard

You'll like it here. 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 Do:

• Build and evolve our JS/TS SDKs.
• Start new things.
• Work in the open.
• Own the type experience.
• Keep us honest across runtimes.
• Work on realtime.
• Track the platform.
• Design in public.
• Make our SDKs legible to AI coding agents.

Qualifications

• Expert-level TypeScript.
• You've authored or maintained a published library with a public API and consumers outside your own company.
• You've worked on open-source projects and know the maintainer side of them.
• npm packaging fluency.
• Testing as a habit.
• Strong written communication.
• Real autonomy.
• 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.

Requirements

• Issue triage at volume, reviewing outside PRs, release automation, changelogs and semver, security reports, and saying no to a feature request without losing the person who asked.
• Unit, type-level and end-to-end testing against a real stack. Every fix comes with a regression test.

Benefits

• Fully Remote: We hire globally. We believe you can do your best work from anywhere.
• ESOP: Every team member receives ESOP (equity ownership) in the company.
• Tech Allowance: Use this budget to set up your ideal work environment.
• Health Benefits: Supabase covers 100% of health insurance for employees and 80% for dependents.
• Annual Off-Sites: Once a year, the entire company gathers in a new city for a week of connection, collaboration, and fun.
• Flexible Work: We operate asynchronously and trust you to manage your own time.
• Professional Development: Every team member receives an annual education allowance to spend on learning.
