Job description

About Usul

Usul is a Silicon Valley AI lab helping America and its allies buy technology at the speed of Amazon Prime. We're Stanford dropouts, MIT AI scientists, and Tier-1 Special Forces Operators dedicating our lives to rebuilding the infrastructure that equips the Western world.

We’re the youngest founders to ever win a US Defense contract. Over the past year, we’ve helped Global 500 companies including RTX, BAE Systems, Palantir and Ukrainian drone manufacturers win $12B in contracts across 30 NATO nations.

You’ll be a backend platform engineer building the core platform infrastructure that world governments will use daily to acquire any technology at the speed of relevance.

Who we’re looking for

  • 2-8 YOE backend infra experience
  • Experience with several of the following: Python, DevOps, Bash, Linux, Kubernetes, Terraform, AWS/GCP, and agentic/LLM tooling.
  • Bonus: Typescript
  • Has passion for solving mission-critical national security problems

About the interview

  • 15-minute screening with Joon (CTO) or Oliver (CPO)
  • 30-minute Culture Fit with Jarren (CEO)
  • 3-hour Technical Interview with Joon (CTO)
  • On-site at San Francisco/DC
  • Offer!

Why work at Usul

  • Culture: Fast‑moving YC‑backed startup with a small, tight‑knit team (currently ~16 people) where each hire has outsized impact. Described as “shipping products that reshape how governments buy technology across the world.” usul.com
  • Work policy: Primarily office‑based in San Francisco (San Francisco Office location per YC). Not explicitly remote/hybrid, but likely in‑person given the high‑trust, collaborative nature of defense/govtech.
  • Perks: Competitive salary ranges (e.g., $120K–$250K for engineering roles) plus equity (0.10%–0.75% for founding roles). ycombinator.com
  • Engineering culture: Strong focus on AI and full‑stack development; opportunities to build critical infrastructure for government procurement; team includes engineers from Stanford, Palantir, MITRE. ycombinator.com
  • Why candidates join: Chance to solve a massive, overlooked problem ($8.4T in government spend), work with top defense investors and clients, and be part of a high‑growth YC startup from an early stage.
