THE OPPORTUNITY

Superhuman Docs' tables started as a custom, in‑memory database designed to run in a browser tab. Our customers have pushed it beyond its limits, and as a result we’re making big changes to our storage and calc engine. This team owns the full vertical: the formula language and its grammar, the AST parser, the execution planner that determines what to compute and when, execution optimization that keeps millions of concurrent user applications responsive, and the performance infrastructure that makes it all work under real-world load. You’ll lead the small team building it while staying hands‑on in the code yourself. The hard part is building a database building block for non‑technical users who are converting their rituals & processes into production software. This means we have to deliver a product that’s cost‑sensitive, enterprise‑grade, and never predictably accessed.

WHAT YOU’LL OWN

• Invalidation, execution, and query planning for the calc engine
• Architectural decisions to scale the infrastructure as usage and document complexity grow
• Technical direction alongside a small team (~5 engineers) — reviewing code and designs, giving fast feedback, and still writing code yourself
• Performance: profiling, benchmarking, and closing the gap between “correct” and “fast” at scale
• Coordination with the teams building on top of the calc engine

WHAT WE’RE LOOKING FOR

You’ve worked on the internals of a database system — query optimization, query planning, SQL execution, storage‑engine internals (B‑Trees, LSM Trees, etc.), or HTAP (hybrid transactional/analytical processing) systems. You don’t need to have built one from scratch; owning a piece of one (a query or storage engine inside a larger system) counts.

• 2-3+ years as an EM or tech lead managing a small team (~5), staying close to the code. This is a player‑coach role — roughly half management, half hands‑on — not a step away from engineering.
• You want to build a real product, not just go deep on infrastructure for its own sake.
• Nice‑to‑have: TypeScript, SQLite, Operational Transforms, WebSockets, OPFS, and React. None of these are gates — strong engineers pick them up fast.

WHAT SUCCESS LOOKS LIKE

Six months in, you’re not just leading the team — you’re one of the people reviewing the hardest query‑planning and execution tradeoffs, and the team has someone to turn to who’s actually worked inside a database before.
