Backend/Fullstack Software Engineer

Our Mission

America’s defense industrial base runs on infrastructure built in the 1980s. Distributors and manufacturers managing our supply chain still manually stitch together email threads, supplier quotes, PDFs, government solicitations, and archaic ERP exports to manage billions of dollars passing through our supply chain in component level assemblies.

SalesPatriot changes that.

We're building the AI-native command center for U.S. defense logistics, eliminating the manual bottlenecks slowing down critical national security workflows. From F-35 bearings to Blackhawk rotor hubs, we’re helping distributors and manufactures quote faster, win more, and deliver the parts that keep America safe.

Quick Facts

• YC W25 company — Top 5% growth in batch
• $1M+ ARR in under 90 days — on track for $5M+ this summer
• Trusted by 1,231+ manufacturers across aerospace and defense
• Backed by YC, SV Angel, Pear VC, and CRV (Raised 5M Seed at 50M valuation)
• We co-live in SF — seriously. We build fast and thrive in the chaos.
• We work 12–15 hour days because we’re obsessed with the mission — not because anyone’s asking us to

What You’ll Work On

• Architect Semi-Structured Data Flows
  Build pipelines that ingest and normalize chaotic inputs (PDFs, Excel, emails, legacy ERP dumps) into structured formats ready for decision-making. Think Palantir Foundry, but tailor built for managing supply-chain at a massive scale.
• Design Human-in-the-Loop Agents Systems
  All of our AI deployments are phased: first, we build UIs that help humans execute and annotate workflows. Then, we inject agents into those flows using the collected data. You’ll help build both phases — human control, then AI augmentation along with the internal tooling that helps us do this at scale.
• Operational UI & Frontend Infra
  Build the frontends that power this phased rollout — allowing operators to view, validate, override, and gradually hand off work to intelligent agents. We don’t believe in “AI magic” we focus on real-world collaboration between software and people.
• AI-Powered Quoting at Scale
  Enable intelligent parsing and automated responses for hundreds of inbound emails a day. Build backend flows that transform noise into fast communication.
• AI Backtesting & Deployment Frameworks
  Develop tooling to test agents on historical data, simulate outcomes, and safely deploy into live environments — all backed by version-controlled workflows.
• AI-Enhanced Data Input Interfaces
  Build intelligent Excel-style tools that let users map any column layout into SQL-backed formats — powered by chain of thought reasoning and schema inference.
• Own End-to-End Systems
  From front-end UI to back-end pipelines to model prompts — you’ll touch every layer and own it through shipping, iteration, and scale.
• Internal Tooling
  Build fast, flexible tools for our FDE’s to deploy new agent workflows, debug outputs, and monitor performance.

Who You Are

• Full-stack & Versatile: You thrive across the stack and learn new tools fast.
• High Intensity Operator: You’re allergic to slow, safe projects.
• Scrappy: Whether it’s cleaning CSVs or writing complex ETL, you’ll do whatever it takes.
• Opinionated but Curious: You speak up, argue well, and change your mind with evidence.
• In-Person Ready: You’re ready to build in SF, in our house, with our team.

Why Join Us

• Founding Experience: Help define the culture, roadmap, and the team from the ground up.
• Real Equity: You’ll own a meaningful slice of a rocket ship.
• Direct National Impact: Your work will influence how defense logistics function in the U.S. — literally.
• Immediate Feedback Loop: No waiting around — you’ll see your work change lives in days.
• No B-Team: You’ll work with brilliant, gritty teammates who push hard and play to win.

What It’s Like

Let’s be real — it’s intense.

We pivot fast, work late, and fight fires constantly. But we’re building something real. Something that reshapes how the defense world moves. If you want certainty, a manager with a spec, or a cozy corporate vibe — this isn’t for you.

But if you thrive on adrenaline, learning fast, and building hard things with people you respect — you’ll feel right at home.

Who Thrives Here

You’ve launched a side project, jumped out of planes, or shipped something everyone said was too hard. You're:

• Unconventional: You don’t follow playbooks — you write them.
• Bold: You take risks, move fast, and fail forward.
• Independent: You don’t need a spec to get started — you figure it out.
• Relentless: Every problem is just a puzzle you haven’t solved yet.

We’re Redefining How Defense Distributors Operate.
