Job description

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.

Why work at SalesPatriot

  • Mission-Driven Impact: Work on a problem that genuinely matters—securing critical supply chains for the US and its allies. Your code directly impacts national readiness.
  • Rapid, Tangible Results: New hires ship code to production within days, not quarters. Short feedback loops with real customers mean your work has immediate, visible impact.
  • High-Caliber Team: Join a small, highly selective team ("nobody likes B players") where you'll learn from top performers from MIT, DARPA, and premier venture funds.
  • Meaningful Equity: As an early-stage company on a hyper-growth trajectory, early employees receive significant equity ownership.
  • Culture of Autonomy: The team values builders who "figure it out without a spec" and "care more about the problem than the title." It's a high-trust, high-autonomy environment.
  • Work Environment: Office-first, in-person culture with two hubs (San Francisco and Warsaw). There is also a "co-living in hacker house" option, emphasizing a tight-knit, intense team culture.
