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, 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 Paul Graham, SV Angel, Pear VC, and CRV

  • Team of 20 co-living in SF & Warsaw Hacker Houses

  • 7-figure ARR transacting ~$50M a week through our system

The role

Our Core Engineers work closely with 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 operations.

  • Full-time, in-person in San Francisco - this is not a remote role

  • Backend-leaning full-stack using Svelte / TypeScript / Postgres

  • Design, develop, and maintain full-stack application functionality end-to-end

  • Organise, track, and deliver multiple projects in parallel

What we're looking for

  • Absolute grinder - motivated by hard problems, not comfortable processes

  • 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

  • Ready to show at least one full-stack project (GitHub repo, web app, or Loom demo)

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

  • Strong knowledge of SQL databases - preferably Postgres; proficient at writing, optimising, and troubleshooting complex queries

  • Strong understanding of software engineering best practices: version control, testing, documentation

  • Ability to work effectively in fast-paced, high-accountability environments

  • Low ego, curious, and intellectually honest - focused on outcomes, not "being right"

Any experience level welcome - new grads considered.

The process

Initial call with engineer → Technical screening → Quick call with founder → Fly out to SF HQ for onsite (on us) → Offer

Compensation

  • $150K-$220K base salary

  • 0.15%-0.20% equity

  • US citizens / visa holders only
