Job Description

Overview:

The Firmware Engineer will be responsible for research, design, and development of firmware for DSP/MCU-based control of Uninterruptible Power Supplies (UPS) and emergency backup power systems and associated peripherals. This involves everything from power electronics control loops, thermal/voltage monitoring and management, battery management, real-time clock, automation features, digital communication protocols, and integration with building management systems (MODBUS, BACnet, cloud connectivity). The Firmware Engineer must be independent and self-driven, a good manager of their own time and priorities, and a team player.

Essential Job Functions include but are not limited to the following:

• End-to-end development and testing of C/C++ firmware for TI DSP or MCU-based control of power electronic circuits in UPS/Inverter products.
• Support for existing (legacy) products in Assembly language as well as C.
• Working frequently in a lab environment to conduct board-level and system-level testing.
• Developing test plans and/or automated test scripts.
• Documenting work, test results, technical guides, and software design documents.
• Designing for manufacturability. Helping to develop end-of-line testing schemes for manufactured products. Troubleshooting firmware/software-related manufacturing issues.
• Dealing with field issues on customer sites.
• Working within a multi-disciplinary team of engineers (electrical, mechanical, magnetics, firmware) and technicians.
• Writing technical manuals for new products or features.
• Self-organizing their time and focus, while aligning their priorities with those of management.
• Providing status updates to management on a regular basis.

Required:

• A bachelor’s degree or higher in Electrical Engineering, Computer Engineering, or Computer Science, with coursework in electrical and electronic circuits, microcontrollers and firmware applications, Assembly language, C or C++, digital communications, physics, mathematics, and statistics.
• 2-3 years of experience working in the electronics industry.
• Strong experience programming in C.
• Experience working with microcontrollers (MCUs) in ‘bare metal’ applications.
• Must be flexible, proactive, and innovative.
• Must possess strong written and verbal communication skills.
• Must enjoy working with new technology in a fast-paced environment.

Preferred:

• Experience with:
• Texas Instruments (TI) C2000 chips.
• Microchip PIC MCUs.
• Atmel Atmega MCUs.
• Experience with Assembly language.
• Experience with Git source control.
• Python skills (for test scripts).
• Ability to program DSP in C language.
• Experience with digital communication protocols including:
• RS485.
• RS232.
• BACnet.
• MODBUS.
• SPI / I2C.
• IP networking (Ethernet, TCP/IP, Telnet/SSH, SNMP).
• Cloud connectivity (IoT, MQTT).
• Work experience in the field of Power Electronics and UPS topologies.
