We are seeking an Embedded Software Engineer to develop the low-level control software, real-time runtimes, and device drivers that directly command test stands and production systems. This role sits at the intersection of real-time embedded engineering and distributed control systems, and is responsible for building performant, deterministic, and fault-tolerant software that drives fieldbus networks, commands actuators, and acquires high-speed signals from scientific instrumentation where safety and accuracy are exceedingly important. The successful candidate will play a central role in defining the real-time architecture, driver standards, and hardware interfaces of mission-critical embedded systems across R&D, manufacturing/test, and plant operations.

Responsibilities
Architect and develop deterministic, safety-critical control software on Linux-based real-time operating systems (e.g., PREEMPT_RT), including scheduling, timing, and fault-tolerant control logic.
Build and maintain industrial fieldbus masters and stacks (e.g., EtherCAT, CAN/CANopen, EtherNet/IP) for hard real-time, high-rate closed-loop control of distributed actuators, drives, and I/O.
Write drivers and interfaces for scientific instrumentation, sensors, and data acquisition hardware for high-speed, kHz-class acquisition across low-level protocols and buses (e.g., SPI, I2C, serial, USB, PCIe, Ethernet).
Own software from development through deployment by building automated build, test, and validation infrastructure.
Perform safety analyses and validate control logic to ensure deterministic behavior and functional safety under both normal and fault conditions.
Work closely with hardware, electrical, and controls engineering teams to bring up new systems and integrate firmware with hardware.
Lead debugging, root cause analysis, and reliability improvements across the full software-to-hardware stack, using oscilloscopes, logic analyzers, protocol analyzers, and other laboratory instrumentation.
Contribute to integrated system testing, commissioning, and continuous improvement of embedded software running on production equipment
