-
Experience with CI/CD pipelines, preferably on AWS/GCP with Docker.
-
Strong Git workflows, including version control using GitHub.

"Grinder" mentality – willingness to work long hours and thrive in a startup environment with rapid changes and uncertainty.
-
U.S. Citizen or Permanent Resident.
Nice to Have:
-
Deep understanding of API design, particularly in OpenAI/Stripe-style integrations.
-
Experience with both RESTful and WebSocket (Socket.io) APIs.
-
A strong portfolio demonstrating past products or projects.
