AI procurement platform for defence parts
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 aerospace, electronics, industrial, and defense supply-chain operations nearly autonomous. Faster quoting. Faster procurement. Full visibility. Real operational intelligence for the companies our nation depends on.
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 Warsaw & SF Hacker Houses
7 figure ARR transacting ~$50M a week through our system
Our Full Stack Engineers work with the platform team and our forward deployed engineers to build the systems our customers run on. Most of that work means integrating with legacy ERPs and email-driven workflows that move real orders every day.
Full time, in person in our Warsaw office. This is not a remote role.
Backend-leaning: Svelte, TypeScript, Postgres.
Design, build, and maintain features end to end, from schema to UI.
Run several projects in parallel and get each one shipped.
Up to one week of international travel per quarter (SF HQ or customer sites).
5+ years of genuine full-stack experience.
Absolute grinder. Interested in co-living (though not required).
You've shipped real full-stack products and can show us one: a GitHub repo, a live web app, or a Loom walkthrough.
You've designed systems on your own, not only built someone else's spec.
Strong in TypeScript and at least one frontend framework (React, Svelte, Next, etc).
Comfortable in SQL, preferably Postgres. You can write, optimize, and debug complex queries, not just call an ORM.
You use AI coding tools every day and understand where the frontier is.
Fluent English, and comfortable working for founders in their early twenties.
Comfortable with ambiguity. Priorities can change week to week.
Low ego, curious, intellectually honest. Focused on outcomes, not on being right.
Initial call with engineer → Technical screening → Quick call with founder → fly out to SF/Warsaw HQ for onsite (on us) → offer.
AI procurement platform for defence parts
SalesPatriot builds an AI-driven procurement platform for defence and aerospace parts distributors and manufacturers. It collects and structures data from government portals, ERPs, spreadsheets, and unstructured email, then automates quote processing and order workflows so suppliers can respond quickly to solicitations (including Pentagon-linked demand) without changing their existing software. The product ties together data sources and automates procurement tasks to speed responses and orders, offering a unified workflow that fits into current systems. It differentiates itself by focusing on deep data integration across diverse sources and end-to-end quote-to-order automation tailored for defense and aerospace customers, and by operating in both the US and European/Asian markets. The company’s goal is to scale its product and commercial teams and expand into commercial aviation and broader procurement markets in Europe and Asia.
