What you'll do:

Develop control software across multiple platforms, including real-time Linux, microcontrollers, and FPGAs
Verify embedded software with Hardware-in-the-loop testbeds and field commissioning activities
Improve software tooling to increase developer velocity and enable new capabilities

What we’re looking for:

Bachelor's degree in a relevant engineering field (computer science, computer engineering, electrical engineering, industrial engineering, etc.)
7+ years relevant experience
Professional experience with embedded, real-time control systems
Professional experience with producing production quality control software
Experience with modern software development lifecycle practices (CI/CD, git version control, unit testing, integration testing, etc
Proficiency with Python
Proficiency with at least one real-time control language (C++, Rust, etc)

Bonus points for:

Experience with mission or safety critical systems

Experience with large-scale industrial systems

Familiarity with real-time Linux

Familiarity with bare-metal micro controllers
