Role Description We’re looking for a Senior Firmware Engineer with deep expertise in wireless communications to help shape the future of Gridware’s connected devices. In this role, you’ll design and optimize firmware that powers resilient, low-power networks—leveraging peer-to-peer, mesh (802.15.4, Zigbee, Thread), Matter, and emerging NTN protocols. Your work will expand device connectivity while reducing dependency on costly gateways, directly impacting performance, reliability, and uptime across a rapidly scaling fleet.

What You’ll Do

• Design and implement firmware for next-gen wireless communication protocols.
• Build and customize mesh networking solutions to extend device coverage and resilience.
• Optimize communication stacks for maximum efficiency under real-world constraints.
• Prototype, test, and iterate quickly with hardware in the loop.
• Partner with hardware and systems teams on protocol design and integration.
• Debug, validate, and tune performance across diverse environments.

What We’re Looking For

• 5+ years of professional experience in embedded/firmware development.
• Proven expertise with wireless communication protocols.
• Direct, hands-on experience with mesh networking (e.g., 802.15.4, Zigbee, Thread, or similar).
• Strong foundation in low-power system design.
• Experience prototyping and testing with hardware.
• Excellent debugging and optimization skills at the firmware/protocol layer.

Bonus Points

• Experience scaling firmware across large, distributed IoT networks.
• Familiarity with Matter, Thread, or similar IoT ecosystems.
• Knowledge of NTN or long-range, low-power communication systems.
• Background customizing and optimizing communication stacks for efficiency.
• Understanding of physical layer trade-offs (bandwidth, latency, power).

This describes the ideal candidate; many of us have picked up this expertise along the way. Even if you meet only part of this list, we encourage you to apply!
