Who We Are
The American Dream (Fast-Tracked)
SalesPatriot is a fast-growing, San Francisco based Defense Tech company. Our co-founder, Maciej Szymczyk, was on Forbes’ “30 Under 30” and was the youngest founder in Y Combinator’s W25 batch.
Backed by Giants
We bridge the gap between Warsaw’s engineering elite and Silicon Valley’s top tier. Our backers include:
- Y Combinator (W25): The accelerator behind Airbnb and Coinbase.
- SV Angel: Early investors in Google, Facebook, and Stripe.
- Pear VC: The visionaries behind DoorDash.
- Polish Power: Supported by the Rafał Brzoska, bringing the best of Polish resilience to the US market.
Our Mission: Modernize Defense Supply Chains
US Defense supply chains operate through outdated technology and inefficient, labor-intensive workflows. We are fixing it.
SalesPatriot is building the AI-native command center to eliminate the manual bottlenecks that slow down defense supply chains. From F-35 bearings to Blackhawk rotor hubs, we’re helping distributors and manufacturers quote faster, win more, and deliver the parts that keep NATO safe.
Warsaw | San Francisco
Our HQ is in San Francisco, with a Core Engineering Hub in Warsaw. We seek relentless builders ready to bypass the corporate ladder. You’ll tackle national security challenges from day one.
What We Offer
We demand the best, so we supply the best.
Top-Tier Pay for Top Performers: $6 500 – $8 500/mo (B2B), increasing upon SF relocation. Top-of-market compensation for top 1% talent.
Meaningful Equity Upside: Significant equity (0.05% – 0.3%) in a YC-backed Delaware C-Corp. When we win the war for supply chain supremacy, you win life-changing wealth.
Warsaw → San Francisco Track: Start in Warsaw, then relocate to San Francisco (HQ) after ~4 months.
High-Caliber Team: Work alongside ex-founders, math olympiads, and engineering prodigies.
Carve Out Your Own Role: No bureaucracy. No “years of service” requirements. Prove your worth and define your own area of ownership in record time.
What You'll Build
You will join the Core Team as a Full Stack Engineer. This is a hands-on engineering role where you carve out your own area of ownership.
- See Your Code in Action: You’re building software that powers defense supply chains. Opportunities to visit defense manufacturers in the US to see the real-world impact of your work.
- Iterate fast: You will ship complete features daily. This includes everything from the Postgres database schema to UI components and critical infrastructure.
- Make ERPs Speak the Same Language: Defense manufacturers run on legacy ERPs. You’ll build AI pipelines that pull quoting data from emails and land it cleanly in any of them.
What You Bring
We are not looking for a corporate senior dev with 10 years of experience in managing Jira tickets. We are looking for a young, obsessed builder (likely with a history of freelancing or side-projects) who wants to win.
The Lifestyle (Non-Negotiable):
- Hacker House: You are ready to live and work in a “hacker house” environment (first in Poland, then in SF).
- Relocation: You must be ready to relocate to San Francisco within ~4 months.
- Intensity: This is a pre-Series A sprint. Expect 12-14-hour days, 7 days a week. We are trading sleep for equity and speed.
The Stack:
You are fluent in TypeScript and Node.js.
- Frontend: We use Svelte/SvelteKit. Experience with React or a similar modern frontend framework is sufficient—you should be comfortable picking up Svelte quickly.
- Backend: We use tRPC for end-to-end type-safe APIs. You should have a strong understanding of backend performance and async job processing (queues, background workers, Trigger.dev or similar tools).
- AI Native Workflow: You don’t just code; you accelerate yourself with Cursor/Claude and understand how to iterate at “AI speed.”
- Builder DNA: We care more about GitHub projects that have real impact than about degrees.
Debrief on Intensity
Read this before applying
This is not a standard 9-5 job. We are a Defense Tech company in hyper-growth mode (Top 5% of YC W25 batch). We are looking for relentless builders - the “outliers” who compress 5 years of career growth into 1 year. If you want work-life balance, look elsewhere. If you want work-life impact - welcome to the team!
