ELIXIR MD Inc
Jr Firmware Engineer
Location: Irvine, CA
(In office only; No remote/hybrid) Company: ELIXIR MD Inc. Industry:
Medical Devices (Global Aesthetic & Surgical Markets)
About Us ELIXIR MD Inc. is a fast-growing fully integrated medical device innovator, headquartered in Irvine, CA, with a proud Made in the USA ethos. Our manufacturing, supply, sales, and support operations are global, with sales in 22 countries (and growing). Our flagship device is transforming the way plastic surgeons practice worldwide. With rapid adoption, global expansion, and highly specialized logistics for a growing portfolio of devices, we are looking for a full-time Junior Firmware Engineer to help design, control, and optimize the embedded intelligence that powers our next-generation platforms.
Position Summary The Junior Firmware Engineer at ELIXIR MD supports the design, development, debugging, and verification of embedded control systems for medical devices. Working closely with the electrical, mechanical, and software teams, this role focuses on real-time firmware for microcontrollers, LED drivers, sensors, and system safety logic within regulated design environments. The engineer will help ensure stable performance, compliance with safety standards, and manufacturability through disciplined firmware design and testing.
Key Responsibilities Develop and maintain embedded firmware for device control, sensing, and communication subsystems. Collaborate with hardware engineers to define I/O pin maps, electrical interfaces, and control loops. Write efficient, maintainable code in C/C++ targeting ARM-based and other embedded microcontrollers. Implement communication protocols (UART, I2C, SPI, CAN, Modbus) and support hardware bring-up. Assist in system integration testing (power-up, LED drive control, thermal/fan management, interlocks). Support board-level debugging using oscilloscopes, JTAG/SWD tools, and logic analyzers. Participate in firmware verification and documentation under ISO 13485 and IEC 62304 frameworks. Contribute to firmware release management (Git, version control, release notes). Collaborate cross-functionally with QA, Software, and Product teams to ensure traceability and system compliance. Assist with prototype testing, thermal tuning, and failure analysis during early design phases.
Qualifications Proficiency in embedded C/C++ development for microcontrollers (STM32, NXP, Microchip, or similar). Familiarity with real-time operating systems (FreeRTOS, Zephyr, or bare-metal firmware). Understanding of circuit schematics, power management, and digital/analog I/O fundamentals. Experience with debugging tools (JTAG, SWD, logic analyzer, oscilloscope). Knowledge of common communication protocols (UART, SPI, I2C, CAN). Familiarity with firmware validation and documentation in regulated (FDA/ISO) environments preferred. Strong analytical and troubleshooting skills. Highly detail-oriented with disciplined coding and version control habits. Excellent collaboration and cross-functional communication skills. Eager to learn in a fast-paced, hands-on medical technology environment. Displays accountability, precision, and proactive problem-solving.
Education & Experience Bachelors degree in Electrical Engineering, Computer Engineering, or related field. 03 years of embedded firmware development experience (internship or project experience acceptable). Experience in medical device, robotics, or industrial control systems preferred. Familiarity with ISO 13485 and IEC 62304 documentation standards is a plus.
