  • After 60 Days: You've taken initiative in designing a scalable architecture for integrating with customer enterprise systems. You've outlined a clear and realistic implementation plan, including milestones for development, testing, and deployment.
  • After 90 Days: You have implemented and tested major features in simulation and on real hardware at the test site and have taken the lead on the future path of our back-office systems.

Basic Requirements: 

  • 5+ years of experience in backend or systems-level software development. 
  • Professional experience in C, C++, Rust, or other systems programming languages. 
  • Strong understanding of operating systems, networking, and concurrency models. 
  • Experience building highly available, high-performance systems. 
  • Proficiency with Linux environments, low-level system interactions, and memory management. 
  • Strong debugging and performance optimization skills for complex distributed systems. 

Preferred Qualifications: 

  • Experience with Rust in production or a strong desire to work with Rust. 
  • Experience in safety critical application spaces such as autonomous vehicles, industrial control equipment, or aerospace. 
  • Experience in or knowledge of rail control systems is greatly preferred. 
  • Familiarity with cloud-based architectures and containerized environments (Docker, Kubernetes).
