About the role

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 Job

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 Svelt/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"

The Process

Call with founder → 1hr technical call with an engineer → fly out to SF/Warsaw HQ (on us) → offer.
