Overview

Position Summary: We are seeking a Senior Embedded Software Engineer with deep expertise in motion control systems, real-time embedded software, and low-level firmware development.

This role focuses on designing, developing, and optimizing firmware for microcontroller-based systems that interface with motors, sensors, and real-time peripherals.

The ideal candidate works comfortably at the boundary of hardware and software and has strong hands-on debugging skills.

Responsibilities Key Accountabilities Essential Functions: Design, develop, and maintain embedded firmware for motion control systems using microcontrollers Develop software on bare-metal and RTOS-based systems with strict real-time constraints Implement and optimize stepper motor control, sensor interfaces, and deterministic control loops Design and implement low-level drivers, including: DMA drivers Interrupt service routines (ISRs) Timer, GPIO, and peripheral drivers Architect and debug RTOS-based systems, including task scheduling, synchronization, memory usage, and ISR interactions Collaborate closely with hardware engineers to: Read and interpret schematics and datasheets Perform hardware bring-up and board-level debugging Interface with and debug embedded peripherals such as: SPI, I²C, CAN bus, UART, PWM, GPIO Apply strong knowledge of computer architecture, including: CPU pipelines, cache behavior, memory hierarchies Microcontroller buses and peripheral architectures Perform advanced debugging using: JTAG-based debuggers Oscilloscopes Logic analyzers Function generators Optimize firmware for performance, reliability, and real-time determinism Create and maintain technical documentation, including design descriptions and test procedures Mentor junior engineers and participate in technical design and code reviews Preferred Skills: Experience with popular RTOS platforms (e.g., ThreadX) Experience with motor control algorithms such as microstepping or closed-loop control Experience with hardware bring-up and production firmware Development experience in regulated industries, including FDA-regulated medical devices, with exposure to design controls and verification/validation practices Knowledge of safety‑critical, real-time, or high-reliability systems Awareness of EMC/EMI considerations in embedded designs Extensive experience developing software for embedded microcontrollers Strong hands-on experience with Real-Time Operating Systems (RTOS), including task design, scheduling, synchronization primitives, and interrupt handling Proven experience designing and implementing: DMA-based data transfers Interrupt-driven software architectures Solid understanding of computer architecture, including cache, memory, and peripheral subsystems Strong knowledge of embedded communication protocols: SPI, I²C, CAN bus, UART Ability to read and interpret hardware schematics Proven experience debugging embedded systems using JTAG or equivalent on-chip debug interfaces Proficiency in hardware/software debugging with: Oscilloscopes Logic Analyzers Function Generators Strong embedded C/C++ programming skills Excellent problem-solving, debugging, and root-cause analysis skills Qualifications Minimum Knowledge & Experience Required for the Position: Bachelor’s Degree plus a minimum 8 years of related experience or Master’s Degree plus a minimum 4 years of related experience or waiver based on experience.

Degree should be in a technical discipline such as Chemistry, Math, Physics, Engineering, or Computer Science. Proficiency with a personal computer and software packages.

Proficient in computer codes (Assembly, C, C++, Java, C#, etc.) found in the development. International Mobility Required: No Travel

Requirements: <5% of time The annual base salary range for this role is currently $130,000 to $160,000 range.

Individual employee compensation will ultimately depend on factors including education, relevant experience, skillset, knowledge, and particular business needs.
