**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!
