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.

Quick Facts

• YC W25 company. Top 5% growth in batch
• Raised $10M+ on a hyper-growth trajectory.
• Backed by Paul Graham, SV Angel, Pear VC, and CRV
• Team of 17 Co-live in our Warsaw & SF Hacker Houses
• 7 figure ARR transacting ~50M a week through our system

The Role

The Senior Software Engineer will work closely with other engineers on the platform team and customer-facing forward deployed teams to design, build, and maintain robust full systems that integrate with complex legacy environments and support high-value, high-impact supply chain systems.

• Backend-leaning fullstack role using Svelte/Typescript/Postgres.
• Design, develop, and maintain full-stack application functionality, including:
• Frontend UI
• Backend services and APIs
• AI workflows and validation systems
• Database schemas and data models
• Organize, keep track of, and deliver multiple projects in parallel

What We’re Looking For

• Ready to relocate to SF full-time. This is not a remote role.
• 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"

The Process

30min intro call → Take-home technical test → 15 min founder call → fly out to SF HQ (on us) → offer.
