Job Summary
We are seeking an Embedded Software Engineer to join our team in the design & implementation of the GridBridge products. This individual would work closely with Power Electronics HW, DSP Engineers, and other R&D personnel. This position requires embedded software engineering skills in the implementation of embedded software with control of hardware and intra-process communications. The platform software is based on a Yocto build of embedded Linux running on an iMX8 processor. Additional bare metal development on an STM32 platform is needed. The GridBridge team operates in a non-hierarchical manner, achieving great success in our team centric approach to development. Our working environment is still structured like a fast-paced start-up.

Responsibilities of this position include but are not limited to:

• Contribute to the design, development, and maintenance of embedded software on Yocto-based Linux (iMX ARM platform).
• Design, development, and maintenance of bare metal embedded software on a STM32 microprocessor.
• Develop and support embedded C/C++ code for controller cards, including integration with peripherals (CAN, RS232, USB, SPI, I2C, A/D, D/A).
• Collaborate with hardware and DSP engineers throughout the product lifecycle.
• Implement and maintain coding standards, documentation, and version control practices.
• Design and integrate system-level software for control, UI, cloud connectivity, and communication protocols.
• Port and integrate protocol stacks (e.g., OpenDNP3) and interface with customer systems.
• Support system testing, manufacturing diagnostics, and deployment activities.
• Contribute to continuous improvement of development processes

Skills

Required proficiencies for this position include but are not limited to:

• 5+ years of experience in embedded software development.
• Proficiency in C/C++ for embedded systems.
• Experience with embedded Linux (Yocto preferred) and shell scripting (e.g., JavaScript, Python).
• Experience with Docker Containers is a plus.
• Strong understanding of communication protocols (I2C, SPI, UART, CAN, Ethernet, LTE).
• Familiarity with debugging tools (e.g., JTAG, oscilloscopes) and version control (e.g., Git).
• Excellent documentation and communication skills.
• Ability to work independently in a startup-like environment.

Desired skills for this position include:

• Background in Smart Grid or utility product development.
• Prior experience in small teams or startup environments.
• Education in Computer Science, Software Engineering, Mechatronics, or Electrical Engineering (advanced degrees or relevant minors a plus).
• Working knowledge of protocol stacks (DNP3, OpenADR, Modbus, and OCPP)
• JavaScript and REACT for user interface design
• MQTT for intra-process communications
• Experience with Docker is a plus
• Development of IoT solutions using AWS or similar
• System testing, Manufacturing diagnostics, built in test/diagnostics (PBIT, IBIT, CBIT)
• Deployment and customer support
• SCADA or other utility standards experience
• Experience using a Requirement Management Tool (RQM) (e.g. DOORS, Visure, etc) for the purpose of tracking and traceability of requirements from product to design and test cases.
• Working with functional safety compliance processes (e.g. IEC 61508 and/or IEC 60730-1) to meet the certification process and all supporting documentation for certification.

Experience
The candidate shall have a minimum of 5 years of applicable experience. Experience in Smart Grid or Utility product development is a plus.

Education
Relevant education would include degrees in Computer Science, Computer Engineering, Software Engineering, Electrical Engineering, Mechatronics with minors or advanced degrees in similar areas.
