Job description

Purple Unicorn, on behalf of SalesPatriot, is hiring an Full Stack Engineer.

Non-negotiable: ALL ROLES ARE ON-SITE IN SAN FRANCISCO. IN ORDER TO BE CONSIDERED YOU MUST BE LOCAL OR WILLING TO MOVE

*** Must be authorized to work in the US***

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.

Quick Facts

• YC W25 company. Top 5% growth in batch
• Raised $10M+ from investors including Paul Graham, SV Angel, Pear VC, and CRV
• Team of 20 co-live in our SF & Warsaw Hacker Houses
• 7 figure ARR transacting ~$50M a week through our system

The Role

Our Full Stack Engineers work closely with other engineers on the platform team and customer-facing forward deployed teams to design, build, and maintain robust full-stack systems that integrate with complex legacy environments and support high-value, high-impact supply chain systems.

• Full time, in-person in SF. This is not a remote role.
• Backend-leaning fullstack role using Svelte/Typescript/Postgres.
• Design, develop, and maintain full-stack application functionality, including:
• Organize, keep track of, and deliver multiple projects in parallel

What We’re Looking For

• Absolute grinder. Interested in co-living (though not required).
• Comfortable with ambiguity and rapid change.
• Track record of shipping fast.
• Experience architecting systems independently
• Motivated by taking an unknown problem, sinking your teeth in, and coming up with a plan of attack.
• Experience in shipping projects and products. Be ready to show us at least one full-stack project (GitHub repo / web app / Loom demo video).
• 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.
• Strong understanding of software engineering best practices, including version control, testing, and documentation
• Ability to work effectively in fast-paced, high-accountability environments
• Low ego, curiosity, and intellectual honesty - focused on outcomes, not “being right
