Senior Embedded Systems Engineer — RTOS, Linux, OTA

Qnergy Inc; Ogden (UT); On-site; USD 110,000 - 160,000; Full time

Job summary

Qnergy Inc is seeking a Senior Embedded Software Engineer to design, build, and support embedded firmware across bare-metal, RTOS, and embedded Linux stacks for our energy products. This is a hands-on role with broad ownership and a path to technical leadership.

You will collaborate with electrical, mechanical, and cloud/software teams to deliver reliable firmware, implement robust CI/CD, and drive hardware-in-the-loop testing for field deployments.

Qualifications

• 7+ years of professional experience in embedded systems, firmware, or embedded software development.
• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field – or equivalent practical experience.
• Experience shipping embedded products that operate in the field (industrial, IoT, energy, automotive, aerospace, or similar).
• Experience taking products from development through certification, manufacturing, and field deployment is a strong plus.

Responsibilities

• Design, implement, and maintain bare-metal and RTOS-based firmware (STM32 / FreeRTOS) for engine controllers, supervisory/system controllers, power electronics, and monitoring systems.
• Develop and support embedded Linux platforms, including system services, networking, and device integration.
• Own productization aspects of firmware: bootloaders, OTA/firmware updates, secure boot, flash and file systems, watchdogs, and low-power operation.
• Integrate and support communication interfaces: fieldbus protocols (Modbus RTU/TCP, CAN, RS-485), remote connectivity (cellular/LTE), and cloud telemetry (MQTT, HTTP) feeding the Qnergy Dashboard.
• Debug complex cross-domain issues using lab equipment (oscilloscope, logic analyzer, debuggers) and contribute to hardware design reviews and board bring-up.
• Collaborate with electrical, mechanical, and cloud/software teams on architecture, interfaces, and design tradeoffs.
• Establish and improve engineering practices for embedded development: version control, code reviews, automated builds, CI/CD for firmware, hardware-in-the-loop testing, and effective use of modern development and AI-assisted tooling.
• Support manufacturing, field service, and customer-facing teams in diagnosing and resolving issues from returned or deployed units.
• Document designs, interfaces, and test procedures to a standard appropriate for safety and reliability-critical products.
