Full Stack Engineer (San Francisco)

The Mission America's industrial base runs on systems built in the 1980s. Billions of dollars in critical components (F-35 parts, industrial assemblies, electronics, bolts, and hoses) still move through email threads, excel sheets, and disconnected ERPs. We're replacing that with an AI-native platform that makes defense, aerospace, and industrial supply-chain operations nearly autonomous. Faster quoting. Faster procurement. Full visibility. Real operational intelligence for the companies our nation depends on.

• Proficiency in TypeScript, JavaScript, and at least one frontend library (React, Svelte, Next etc).

• Knowledge of SQL databases, preferably Postgres.

• Proficiency in writing, optimizing, and troubleshooting complex SQL queries for data extraction, transformation, and integration.
