Job description

Overview

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

• 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

• 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.

Compensation & Benefits

The annual base salary range for this role is $130,000 to $160,000. The role is eligible for medical, dental, and vision insurance, a 401(k) plan with employer match, and paid vacation and sick leave. Additional benefits may include performance‑based bonuses for select professional roles.
