JOB SUMMARY

The Sr. Firmware Engineer will develop, sustain, and provide technical ownership of embedded firmware solutions for Single Phase UPS products. The role focuses on real-time DSP/MCU firmware for power conversion systems, including digital control, signal acquisition and processing, protection algorithms, hardware/firmware integration, system synchronization, and multi-processor communication.

The engineer will work closely with global engineering teams supporting new product development and sustaining activities and will apply in-depth knowledge of Single Phase UPS architectures, firmware platforms, product-specific control strategies, interfaces, and engineering processes. The position also provides technical guidance to firmware engineers and supports product integration, laboratory validation, troubleshooting, and root-cause analysis throughout the product lifecycle.

PRINCIPAL DUTIES & RESPONSIBILITIES

Develop and maintain embedded firmware for Single Phase UPS products using DSP and MCU-based platforms.
Develop high-quality C/C++ firmware for bare-metal and real-time operating system environments.
Design and implement timing-critical power electronics functionality including PWM generation, synchronized ADC acquisition, digital control loops, protection algorithms, and real-time signal processing.
Develop and maintain firmware associated with AC/DC and DC/AC power conversion, inverter control, PFC, battery operation, and UPS protection functions.
Develop and support algorithms for UPS synchronization, paralleling, active load sharing, and redundant power systems.
Develop and maintain firmware for multi-processor and multi-controller embedded architectures.
Design and maintain reusable firmware architectures, interfaces, drivers, and Hardware Abstraction Layers across embedded platforms.
Integrate firmware with power electronics hardware, communication interfaces, sensors, programmable logic, and other embedded subsystems.
Perform hardware bring-up, firmware integration, laboratory testing, troubleshooting, and root-cause analysis for new and existing products.
Support firmware development throughout the product lifecycle, including new product development, sustaining engineering, qualification, and production support.
Maintain and improve firmware configuration management, build, verification, and release processes.
Support automated firmware build and verification activities using Git-based development workflows and CI/CD tools.
Support implementation of applicable embedded cybersecurity and secure development requirements.
Create and maintain technical documentation related to firmware architecture, interfaces, design decisions, and product-specific implementations.
Collaborate with cross-functional global engineering teams and provide technical guidance, design reviews, troubleshooting support, and mentorship to firmware engineers.

REQUIREMENTS

BS or above in Electrical Engineering, Electronics Engineering, Computer Engineering, Computer Science, or equivalent experience.
10+ years of experience in embedded firmware, power electronics, digital control, or related product development.
Strong experience developing or sustaining embedded firmware for UPS, inverter, power conversion, motor control, or similar real-time power electronics products.
Strong C/C++ development skills for bare-metal and real-time embedded systems.
Hands-on experience with DSP and MCU-based embedded control platforms, preferably TI C2000 or similar real-time processors.
Strong understanding of real-time embedded systems, including interrupts, task scheduling, synchronization, deterministic data acquisition, and inter-processor communication.
Strong knowledge of digital control, digital signal processing, PWM generation, ADC acquisition, feedback control, and protection algorithms.
Strong understanding of AC/DC and DC/AC power electronics, inverter systems, PFC, batteries, protection functions, and power conversion architectures.
Experience with UPS paralleling, synchronization, load sharing, redundant systems, or comparable multi-converter control architectures.
Experience working with multi-controller or multi-processor embedded architectures.
Experience with hardware/firmware integration, embedded system bring-up, debugging, laboratory validation, and root-cause analysis.
Experience with Git-based source control and structured firmware development workflows.
Ability to communicate complex technical concepts and collaborate effectively with cross-functional and globally distributed engineering teams.
Demonstrated ability to provide technical guidance and mentorship to other engineers.

PREFERRED QUALIFICATIONS

Experience with Single Phase UPS products, architectures, control strategies, or related power conversion systems.
Experience with FreeRTOS, CMSIS-RTOS, or similar real-time operating systems.
Experience with FPGA/CPLD integration and programmable logic used in embedded power electronics systems; familiarity with Intel/Altera devices and Quartus Prime is a plus.
Experience with embedded firmware CI/CD, automated builds, artifact generation, and release automation, preferably using GitLab CI/CD.
Familiarity with embedded cybersecurity practices, SBOM generation, secure software development, or SSDF-aligned processes.
Experience with Python and/or MATLAB for engineering automation, data analysis, algorithm development, or validation.
Experience with automated testing, HIL environments, or high-power hardware/firmware validation.
