Summary: A Firmware Engineer II is responsible for the design, development, testing, and maintenance of embedded firmware for microcontroller-based electromechanical gate and door products. This is a highly hands-on, hardware-oriented role focused on low-level embedded systems (bare-metal and RTOS), not embedded Linux or application-layer development. The ideal candidate enjoys working with hardware, including board bring-up, debugging real circuits, and interacting directly with electrical designs.

You will contribute to products that are released into medium and high-volume manufacturing and be involved throughout the product lifecycle, including architecture discussions, board bring-up, debugging, validation, and field reliability improvements. This role emphasizes low-level firmware development, technical execution, collaboration, and ownership of firmware components rather than OS-based development or direct people management.

Salary is $120,000 to $140,000 depending on experience.

Location: Kent, WA. (fully onsite)

Primary Responsibilities:

• Design, develop, and maintain embedded firmware for microcontroller-based systems used in vehicular gate operators.

• Develop production-quality firmware in C/C++ for real-time embedded systems, including bare metal and RTOS-based applications.

• Implement and debug low-level drivers and hardware interfaces directly on microcontrollers (no embedded Linux).

• Collaborate closely with electrical engineers during schematic review, board bring-up, debugging, and hardware/firmware integration.

• Debug hardware/firmware issues at the signal level (GPIO, SPI, I2C, UART, ADC, PWM, RS485, etc.)

• Participate in firmware architecture discussions and contribute to design decisions for new products and feature enhancements.

• Effectively use hardware debugging tools such as oscilloscopes, logic analyzers, and debuggers to diagnose and resolve issues.

• Support manufacturing introduction, validation testing, and ongoing product reliability improvements.

• Document firmware design, behavior, and interfaces through code commits, specifications, and technical documentation.

• Work effectively within Git-based version control workflows, including code reviews and collaborative development.

• Maintain awareness of applicable safety and regulatory requirements (e.g., UL 325) and how they impact firmware design.

• Provide technical support and collaboration with other engineering disciplines and departments as needed.
• Stay current with embedded systems best practices and contribute to continuous improvement of development processes.

Note: This role does not involve embedded Linux, application-layer development, or high-level OS-based driver development

Qualifications:

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent experience.

• 3-7 years of experience developing firmware on microcontrollers (bare-metal or RTOS) for production hardware.

Knowledge, Skills, and Abilities:

• Software: High proficiency in C for embedded microcontrollers. Experience using higher-level languages (e.g. Python) for testing, scripting, or tooling is a plus.

• Strong understanding of microcontroller peripherals (timers, interrupts, ADC, PWM, communication interfaces)

• Experience with common microcontroller families and IDEs (e.g., ST, Microchip, TI, NXP).

• Experience with RTOS-based firmware architectures.

• Ability to read and understand schematics and basic circuit design.

• Hands-on experience with hardware debugging tools such as oscilloscopes, logic analyzers, and JTAG/SWD debuggers.

• Experience using Git or similar version control systems in a team environment.

• Advantageous to have experience in: BLDC Motor control, Battery and Solar management, standard wired and wireless embedded communication protocols, Embedded Web Servers, low power/standby modes and Exposure to safety-critical or regulated products.

• Strong problem-solving skills and attention to detail.

• Ability to communicate effectively with electrical, mechanical, and test engineers.

• Comfortable working in a small, collaborative engineering team.

Candidates with primarily embedded Linux, application-layer, or high-level software backgrounds (e.g., Yocto, kernel drivers, UI/backend systems) are not a fit for this role.
