From Parallel's posting. “We” and “our” refer to the employer.
Parallel Systems is pioneering autonomous battery-electric rail vehicles designed to transform freight transportation by shifting portions of the $900 billion U.S. trucking industry onto rail. Our innovative technology offers cleaner, safer, and more efficient logistics solutions. Join our dynamic team and help shape a smarter, greener future for global freight.
Backend Software Engineer II
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.
You understand the core concepts behind train control (movement authorities, bulletins, switches, and signals) and how they're implemented technically in our system through motion rules and Parallel blocks. You've added support for one or two missing edge cases in train control.
You've added support for a new train control feature, such as movement authorities that are only valid depending on the movement of other trains. You analyzed the requirements from specs, wrote a technical spec covering the necessary backend and UI changes, and implemented them in our codebase. You've also begun learning the concepts behind PTC and reading the associated specs.
You've added support for several new train control features and have a solid understanding of the gap between what's required to support PTC and what exists in our system today.
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.
