## 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 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:
- 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

- 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"

## About SalesPatriot

## Company Overview
- **One-liner**: SalesPatriot is building an AI-native operating system for defense and aerospace supply chains, automating procurement, quoting, and sourcing for distributors and OEMs.
- **Entity Type**: Private (Seed-stage, YC W25)
- **Headquarters**: San Francisco, California, United States (with a second office in Warsaw, Poland)
- **Founded**: 2024
- **Founders**: Nelson Ray (Co-Founder & CEO), Ben Rhodes-Kropf (Co-Founder & CTO), Maciej Szymczyk (Co-Founder)

## Core Business
- **Primary industry/industries**: Defense and Space Manufacturing, Supply Chain Software, AI for Enterprise
- **Target customers**: B2B, specifically defense and aerospace distributors, OEMs, and manufacturers who manage complex, multi-source procurement and government (DoD) contract bidding.
- **Mission or purpose statement**: To replace fragmented, legacy supply chain systems running on email, spreadsheets, and disconnected ERPs with an AI-native platform that makes quoting, procurement, and sourcing nearly autonomous, thereby strengthening the industrial base of the United States and its allies.

## Products & Services
- **SalesPatriot Platform (AI-Native OS)**: An integrated suite of AI workflows for sales and supply chain teams. It automates RFQ (Request for Quote) processing, procurement, data entry, and sourcing. Provides real-time visibility for executives into the entire supply chain, aggregating data from ERPs, CRMs, email, and marketplaces into a single, searchable interface.
- **Defense & Aerospace Module**: Specifically designed to help manufacturers win DoD solicitations by automating opportunity capture, contract research, and bid management.
- **Distribution Module**: End-to-end AI workflows for high-volume quoting, sourcing, and inventory management.
- **Procurement Module**: Autonomous workflows for teams managing complex, multi-source procurement operations.
- **Forward Deployed Engineering**: A service model where SalesPatriot engineers embed directly with customer teams to configure, integrate, and optimize the AI platform in their specific operational environment.

## Market Standing
- **Valuation/Market Cap**: Not disclosed.
- **Total Funding**: **$5.5M** (as of late 2025). Consists of a $500k pre-seed from Y Combinator (March 2025) and a $5.0M seed round led by **CRV** (November 2025), with participation from **Pear VC**, **SV Angel**, and **Paul Graham**.
- **Key Metric**: **17 Employees** (+175% YoY growth). Top 5% growth in its Y Combinator W25 batch.
- **Growth Signals**: Hyper-growth trajectory from a top-performing YC batch; rapid headcount expansion; opening a second office in Warsaw, Poland; strong investor backing from top-tier venture firms; a focus on a deeply strategic, non-cyclical market (US defense supply chain).

## Competitive Advantages
- **Focus on National Security Supply Chain**: Solves a genuinely broken, high-stakes problem for the US industrial base, creating a strong "mission-driven" moat.
- **Forward Deployed Model**: Engineers embed with customers, leading to deep integration, high switching costs, and rapid, real-world impact that can't be replicated by a simple SaaS tool.
- **AI-Native Architecture**: Purpose-built from scratch for modern AI workflows, replacing legacy systems from the 1980s rather than layering AI on top of them.
- **Elite Team & Culture**: A small, high-caliber team with backgrounds from MIT's Han Lab, DARPA, D.E. Shaw, and top universities, creating a culture of high ownership and technical excellence.

## Strategic Focus
- **Aggressive Hiring**: Actively building out its engineering teams in both San Francisco and Warsaw to accelerate product development and customer deployments.
- **Customer Density**: Prioritizing deep, high-impact deployments with key players in the defense and aerospace supply chain over a broad, shallow customer base.
- **Product Expansion**: Moving from core RFQ automation into a full end-to-end operating system that covers procurement, distribution, and supply chain visibility.
- **Geographic Expansion**: Using the Warsaw office as a hub to tap into a deep pool of technical talent in Europe.

## Why Work Here
- **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.
