Mentor and guide junior engineers, helping shape team culture and elevate skills across the organization.
What We’re Looking For
5+ years of professional software engineering experience building backend systems or full-stack applications.
Strong proficiency in TypeScript and at least one modern backend OOP language (Java, Go, Python, C#, or similar).
Hands-on experience with React for frontend development.
Experience designing and consuming GraphQL APIs .
Proficiency in Ruby on Rails backend development.
Demonstrated track record of shipping production software with real-world impact.
Experience leading technical projects or mentoring junior engineers.
Background working in a high-ownership startup environment (Series A–C scale or similar).
Strong CS fundamentals, ideally from a rigorous academic or professional background.
Comfort working on federal defense-related projects.
Experience with Rust or Node.js is a plus.
A GitHub profile or portfolio showing recent, hands‑on coding activity is a plus.
