Visa Sponsorship

About the role

We're looking for Backend Engineers with 2-8 years of experience who can build and own core backend architecture and infrastructure for our AI platform. You should be deeply technical, comfortable working at startup speed, and excited about putting the best technology in the hands of warfighters and government operators.

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

What you'll do:

  • Design and build the core backend architecture powering Usul's AI platform for government contract capture
  • Own backend systems end-to-end — from data pipelines and API design to deployment and scaling
  • Work closely with forward-deployed engineers and the product team to ship features that serve Special Forces, Fortune 500 defense contractors, and other Department of War initiatives
  • Build and integrate AI agents and LLM-powered workflows that help customers identify and win contracts
  • Collaborate with a small, high-output engineering team (6 engineers, founders included) shipping code daily
  • Occasionally travel to customer sites (a few days per month) to gather requirements and iterate alongside operators
