This is PlanetScale's signature engineering role. Serverless Database Engineers build the serverless MySQL platform powered by Vitess — the open-source database clustering system originally created at YouTube to scale MySQL. PlanetScale is private ($1.2B valuation) and headquartered in San Francisco. The platform provides database branching (like Git branches for your database schema), non-blocking schema changes, and serverless scaling — capabilities that no other MySQL platform offers. Engineers at PlanetScale work on both the Vitess open-source project and the proprietary PlanetScale platform. [Source: PlanetScale Serverless DB Eng Comp 2025-2026]

What Makes This Role Unique
The Serverless Database Engineer works across PlanetScale's core technology:
- Vitess Core: Contributing to the open-source Vitess project — horizontal sharding, query routing, and connection pooling for MySQL
- Database Branching: Git-like branching workflows for database schemas — PlanetScale's signature feature
- Non-Blocking Schema Changes: Online DDL that allows schema migrations without downtime
- Serverless Architecture: Auto-scaling database compute and storage that adjusts to workload
- Global Edge Deployment: Edge-optimized database access for low-latency global applications
Global Levers
- Vitess + Serverless Innovation: "PlanetScale combines Vitess (battle-tested at YouTube/Google scale) with serverless database innovation (branching, non-blocking schema changes). This combination is unique in the database market."
- Open-Source Reputation: "My contributions to Vitess are publicly visible and build both PlanetScale's brand and my professional reputation."
- Smaller Company Equity Risk: "PlanetScale at $1.2B is earlier-stage than Cockroach Labs ($5B) or MongoDB (public). I need a larger equity grant to compensate for the higher risk."
- Cockroach Labs/MongoDB Counter: Both offer higher valuations or liquid equity. Frame: "CockroachDB offers equity at $5B valuation, and MongoDB offers liquid RSUs. PlanetScale's $1.2B valuation needs a proportionally larger equity grant."
Negotiate Up Strategy: "I'm targeting $345K total comp with equity at $230K over 4 years and acceleration on change of control. I'm building the serverless MySQL platform on Vitess — a unique position in the database market. I have offers from Cockroach Labs and MongoDB." Counter at $195K-$220K equity with acceleration is competitive.
