Backend Software Engineer II
About The Position
Parallel Systems is seeking a Software Engineer II to help build the train control software that lets our autonomous rail vehicles operate safely on the rail network. You'll work on the backend systems, written primarily in Rust, that model how trains are authorized to move: movement authorities, bulletins, switches, and signals, implemented in our system as motion rules and Parallel blocks. This is a hands-on role with a clear growth path. You'll start by closing edge cases in our existing train control logic, move on to owning new features end to end (from reading railroad specs through technical design, backend, and UI changes), and grow into a core contributor on our path to supporting Positive Train Control (PTC). Prior rail experience is not required; curiosity and a willingness to learn a deep domain are.
Requirements
- Bachelor's degree in computer science, computer engineering, or a related field, or equivalent practical experience.
- 3+ years of experience in backend or systems-level software development.
- Experience in C, C++, Rust, or other systems programming languages.
- Proficiency with Linux environments, low-level system interactions, and memory management.
Nice To Haves
- 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).
Responsibilities
- Implement and extend backend features for critical train control applications, adding support for new train control concepts with guidance from senior engineers.
- Develop and maintain system-level software written primarily in Rust.
- Improve the reliability and correctness of existing code by finding and fixing edge cases in train control logic.
- Write and test code that meets our safety, security, and compliance standards.
- Debug and diagnose issues in simulation and on real hardware, escalating complex problems when needed.
- Participate in code reviews and technical discussions and help write technical specs for the features you build.
Benefits
- Fair and transparent compensation
- Commitment to diversity in the workplace
- Inclusive environment
- Reasonable accommodations for persons with disabilities
