Principal AI Infrastructure Engineer
New Yesterday
Our Mission America’s defense industrial base runs on infrastructure built in the 1980s. Distributors — the backbone of 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 AI infrastructure to eliminate 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 — not in months, but in days.
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 We're building the AI-native command center for U.S. defense logistics — turning thousands of daily requests for urgent parts (bearings, wires, landing gear, custom machined parts) into structured, automated workflows. You'll work at the frontier of full-stack engineering, LLM infrastructure, and human-in-the-loop systems that power national supply chains. 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 battle-hardened for quoting ops at massive scale.
Design Human-in-the-Loop Agentic 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 and fast.
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. This isn’t “AI magic”; it’s real-world collaboration between software and people.
AI-Powered Quoting at Scale
Enable intelligent parsing and automated responses for hundreds of inbound RFQs per day. Build backend flows that transform noise into winning quotes.
AI Backtesting & Deployment Frameworks
Develop tooling to test agents on historical data, simulate outcomes, and safely deploy into live quoting 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 GPT model prompts — you’ll touch every layer and own it through shipping, iteration, and scale.
Internal Tooling That Actually Works
Build fast, flexible tools for our team to deploy new agent workflows, debug outputs, and monitor performance — inspired by Foundry, but leaner, faster, and deeply verticalized.
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.
All roles are on-site in San Francisco. We live together, We work together.
Living expenses fully covered. Food and Housing is taken care of ( https://www.zillow.com/homedetails/23-Robinhood-Dr-San-Francisco-CA-94127/15135754_zpid/?mmlb=g,22 ).
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. Don’t see your role? Apply anyway. If you’re exceptional, we’ll make room.
Reach out. Show us what you’ve got. Simple as that.
