Responsibilities

Designs and maintains the controller processes that run on safety-critical hardware, focusing on fast, deterministic binaries, memory-based IPC, and integration with field and TCP-based protocols

Qualification

C++RustMemory managementInter-process communicationReal-time executionIndustrial communication protocolsDebuggingPerformance trackingConcurrency patternsHardware-in-the-loop testing

Required

You have 6+ years of experience building C++ or Rust software that runs on or near safety-critical hardware, with a strong focus on correctness and reliability

You have deep understanding of memory management and inter-process communication (IPC), and you are comfortable designing and debugging high-performance binaries that pass data efficiently between processes

You have hands-on experience with real-time or near-real-time execution, and you care about low jitter, latency, and throughput, using common tools to track down performance and memory bottlenecks

You are comfortable integrating with industrial communication protocols (e.g., CAN, LXI, Modbus, RMC/DMCP, OpenDAQ or similar), including moving data reliably over TCP between controllers and higher-level systems

Preferred

Experience designing and operating systems running on a real-time OS or environments with tight real-time constraints

Experience with lock-free or low-contention concurrency patterns for high-throughput data exchange between processes

Familiarity with time-sensitive networking, deterministic scheduling, or other techniques used to coordinate multiple controllers in a safety-critical environment

Prior experience bringing up or debugging hardware-in-the-loop test setups for controllers, including working directly in lab environments with instruments and test equipment
