Supalite Engineer

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 engineers to join the team building Spark, a lightweight implementation of Supabase written in Rust. It runs on an embedded SQLite-based engine with a Postgres-compatible SQL layer, and ships a PostgREST and Auth compatible API, so applications written against @supabase/supabase-js work as-is. It exists because AI builders and platform partners need a database they can give to every prototype without the cost or the wait: sub-second provisioning, a footprint small enough to run inside a sandbox, and an upgrade path to full Supabase when an app graduates to production.

This is a role with a lot of agency. Small team, working product, patterns still to be set. You'll own large areas end to end and make real decisions from day one.

What You'll Be Responsible For In this role, you'll: Grow API compatibility with the Supabase client, keeping behavior faithful to hosted Supabase and backed by conformance tests Bring more of the Supabase stack to Turso/SQLite Find and work around gaps in the underlying database engine, with minimal repros and tests Build and harden the path for upgrading a project from Spark to full Supabase Own the developer experience end to end: the CLI, local tooling, and docs Build and harden the hosted offering while keeping the low cost structure in mind, kept loosely coupled so the implementation can be swapped without a rewrite Work directly with design partners and turn real-world migration and integration friction into a sharper product Engage with the open-source community and contribute back to the broader Supabase stack You Might Be a Good Fit If You Have substantial backend or full-stack experience with strong fluency in Rust, have shipped production Rust, and have built or contributed to a backend system, framework, or developer platform before Are a strong generalist, comfortable moving across the stack from API design to storage internals to infrastructure, and picking up whatever the problem needs Read unfamiliar code without friction.
