Staff Engineer - Firmware Cellular

This role is ideal for an engineer who has hands-on experience with cellular modem integration, embedded Linux development, and low-level firmware rather than RF planning or carrier network engineering. You will work on firmware responsible for maintaining reliable, secure, 24/7 communication between embedded devices and cellular networks., * Design, develop, and maintain embedded firmware for Linux-based communication devices.

• Develop software primarily in C within embedded Linux environments.
• Work in both Linux kernel space and user space.
• Develop and maintain firmware using Buildroot Linux or similar embedded Linux distributions.
• Integrate, configure, and validate cellular modem functionality.
• Support board bring-up activities and hardware integration.
• Troubleshoot cellular connectivity issues including dropped connections and network reliability.
• Support testing related to cellular carrier certification.
• Collaborate with hardware, firmware, systems, and QA engineers throughout the product lifecycle.
• Participate in code reviews, debugging, and performance optimization.
• Contribute to secure communication and IoT connectivity initiatives.

• Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or a related field.
• 7+ years of embedded firmware development experience.
• Strong proficiency in C programming.
• Extensive experience with Embedded Linux.
• Experience working in both Linux kernel space and user space.
• Experience with Buildroot Linux or similar embedded Linux distributions.
• Strong understanding of Linux networking fundamentals.
• Experience developing firmware for embedded communication devices.
• Experience integrating and troubleshooting cellular modems.

Preferred Qualifications

• Experience with Telit or similar cellular modem platforms.
• Experience with board bring-up.
• Knowledge of wireless networking technologies.
• Familiarity with cellular certification and carrier testing.
• Understanding of IoT security concepts.
• Basic Java knowledge.
• Experience supporting products through manufacturing and production.

Ideal Background

Candidates may come from industries including:

• Embedded Systems
• Industrial Automation
• Smart Devices
• IoT
• Telecommunications
• Networking
• Semiconductor
• Wireless Communications

Experience with companies focused on embedded hardware, networking equipment, industrial controls, wireless communications, semiconductor products, or connected devices is highly desirable.

What We’re Looking For

This is not a cellular network planning or RF engineering role.

The ideal candidate has built firmware that directly interfaces with:

• Embedded Linux platforms
• Cellular communication modules
• Modems
• Device networking stacks
• Wireless connectivity
• Always-connected embedded devices

Candidates whose experience is primarily focused on carrier network planning, RF optimization, or telecommunications infrastructure without embedded firmware development are unlikely to be a fit.
