SDK Engineer - Kotlin

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 Kotlin SDK Engineer to join our SDK team and help bring first-class Supabase support to the Android and Kotlin Multiplatform ecosystems. You'll work closely with the broader SDK team, the developer community, and product engineering, helping us design, build, and maintain a Kotlin SDK that feels native to the ecosystem and scales to millions of developers. 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 Supabase Kotlin SDK, including Auth, Database, Storage, Functions and Realtime clients - Define API conventions and patterns that feel idiomatic to Kotlin developers — coroutine-native, expressive, and consistent with Android and KMP ecosystem expectations - Drive the SDK roadmap, identifying gaps and prioritizing improvements based on developer feedback and Supabase product direction - Engage the Android and Kotlin developer community through GitHub, Discord, and open source — triaging issues, reviewing contributions, and iterating in the open - Collaborate with the broader SDK team to maintain consistency, share patterns, and raise the quality bar across all supported languages - Write documentation, guides, and code samples that help developers get started quickly and go deep with confidence WHAT YOU BRING - Have 5+ years of experience building production Kotlin applications across mobile, web, or desktop - Are deeply familiar with the Kotlin ecosystem — coroutines, Flow, Gradle, Jetpack libraries, and the conventions Kotlin developers expect in a well-designed library - Have prior experience building SDKs, libraries, or other developer-facing products - Are comfortable working across multiple languages and drawing on patterns from other ecosystems - 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. - Health Benefits Supabase covers 100% of health insurance for employees and 80% for dependents, wherever you are. Your wellbeing and your family’s health are important to us. - Annual Off-Sites Once a year, the entire company gathers in a new city for a week of connection, collaboration, and fun. It’s a highlight of our year. - Flexible Work We operate asynchronously and trust you to manage your own time. You know what needs to be done and when. - Professional Development Every team member receives an annual education allowance to spend on learning—courses, books, conferences, or anything that supports your growth. ABOUT THE TEAM Supabase was born-remote and open-source-first. We believe our globally distributed team is our secret weapon in building tools developers love. - 280+ team members - 55+ countries - 20+ languages spoken - $500M raised - 500,000+ community members We move fast, build in public, and use what we ship. If it’s in your project, we probably use it in ours too. We believe deeply in the open-source ecosystem and strive to support—not replace—existing tools and communities.
