Embedded Software Engineer
Remote or Edison NJ Hybrid
Job Description
The Embedded Software Engineer will join a team of talented engineers designing, developing, and optimizing firmware for Battery Management Systems (BMS) tailored to the Eos battery technologies, ensuring safety, reliability, and compliance with industry standards such as UL 60730 Annex H.
This role involves using the V-model of software design, driving safety-critical compliance with UL 60730 Annex H, and ensuring seamless integration of firmware with hardware components like STM32 microcontrollers, CAN/CANFD, RS-485 protocols, ADC-s, etc.

Responsibilities

• Design, documentation, development, and maintenance of embedded firmware for generations of Eos Battery Management Systems, ensuring adherence to the V-model and compliance with UL 60730 Annex H functional safety standards.
• Implementation of diagnostics, fail-safe mechanisms, and safety features in BMS firmware, aligning with UL 60730 Annex H requirements.
• Implementing communication interfaces (e.g., CAN/CANFD, RS-485, I2C) for real-time data transmission and control of battery systems.
• Hardware-Software Integration: Collaborate with hardware engineers to ensure proper integration of firmware with BMS hardware components, including sensors, and power electronics, conducting safety validation and performance testing.
• Create technical documentation and ensure traceability and quality per V-model methodologies.
• Support troubleshooting tools and commissioning processes.
• Root Cause Analysis: Contribute to investigations into firmware-related failures, implementing corrective actions to improve system reliability.
• Practice continuous learning.
• Other duties, responsibilities and activities may change or be assigned at any time with or without notice.

Education and Experience

• Bachelor’s degree in electrical engineering, computer engineering, or related field required.
• Master’s degree in electrical engineering, computer engineering, or related field preferred.
• Minimum of 2 years’ experience. This may include projects at university or personal projects.

Knowledge, Skills, and Abilities

• Specific evidence of excellence.
• Problem-Solving: Exceptional problem-solving ability, including troubleshooting complex software and hardware integration issues and implementing scalable solutions.
• Technical Proficiency: Strong background in C for embedded systems, real-time operating systems (RTOS), and microcontroller-based development (e.g., STM32 family).
• Familiarity with development of safety-critical embedded systems. Knowledge of safety standards such as IEC 60730 Annex H or similar is a plus.
• Communication Protocols: Expertise in CAN bus, CANFD, RS-485, SPI, I2C, other protocols.
• Collaboration: Excellent interpersonal and communication skills to work effectively with cross-functional teams and clearly articulate technical concepts.
• Knowledge of embedded security practices (e.g., secure bootloaders, encryption).

Travel

• Local Travel: Less than 10%
• Overnight/North America: Less than 10%

Working Conditions

• Office Environment - Must be able to remain in a stationary position 50% of the time and occasionally move about inside the office to access file cabinets, office machinery, etc. Required to have close visual acuity to perform an activity such as: preparing and analyzing data and figures; transcribing; viewing a computer terminal; extensive reading. May be required to exert up to 25 pounds of force occasionally to lift, carry, push, pull or otherwise move objects, including the human body.
• Factory - The worker may be subject to hazards. Includes a variety of physical conditions, such as proximity to moving mechanical parts, vibration, moving vehicles, electrical current, exposure to temperature changes or exposure to chemicals. While performing the duties of this job, the employee may be exposed to fumes, airborne particles, odors, dust, mists, and gases. The noise level in the work environment can be loud. Required to have close visual acuity to perform an activity such as: preparing and analyzing data and figures; transcribing; viewing a computer terminal; extensive reading; visual inspection involving small defects, small parts, and/or operation of machines (including inspection); using measurement devices; and/or assembly or fabrication parts at distances close to the eyes. Machinery operation requires the use of safety equipment to include but not limited to eye safety glasses, hearing protectors, work boots, and lab coats. May be required to exert up to 50 pounds of force occasionally to lift, carry, push, pull or otherwise move objects, including the human body.
• Customer/Partner Locations – Employee may visit customer or partner locations that may be comprised of office, manufacturing floor, laboratory environments and construction sites depending on the location and reason for visit.

• Design, documentation, development, and maintenance of embedded firmware for generations of Eos Battery Management Systems, ensuring adherence to the V-model and compliance with UL 60730 Annex H functional safety standards.
