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.

Proven expertise with wireless communication protocols.
Background customizing and optimizing communication stacks for efficiency.
Direct, hands-on experience with mesh networking (e.g., 802.15.4, Zigbee, Thread, or similar).
Experience prototyping and testing with hardware.
Excellent debugging and optimization skills at the firmware/protocol layer.
Familiarity with Matter, Thread, or similar IoT ecosystems.
Understanding of physical layer trade-offs (bandwidth, latency, power).
Experience scaling firmware across large, distributed IoT networks.
Strong foundation in low-power system design.
Knowledge of NTN or long-range, low-power communication systems.
5+ years of professional experience in embedded/firmware development.

Benefits

Company-paid training

“Off the Grid”, a two week per year paid break for all employees.

Health, Dental & Vision (Gold and Platinum with some providers plans fully covered)

Alternating day off (every other Monday)

Company

Overview

$26.4M Series A

Funding Round

Secured significant investment from notable firms including Sequoia, Lowercarbon, and Fifty Years.

70% Outage Reduction

Service Improvement

Customers experienced a dramatic decrease in the duration of power outages thanks to Gridware's technology.

10,000+ Poles

Deployment Scale

The system has been installed across a vast network spanning thousands of poles and miles of power lines.

7× Revenue Growth

Financial Achievement

The company experienced rapid expansion and success in its first year of operation.

Founded by a former lineman and two Berkeley engineers to revolutionize power grid awareness.
Flagship Gridscope device provides edge analytics and alerts even during outages.
Technology integrates multiple types of sensing to detect hazards like fallen limbs.
After a pilot with PG&E, expanded operations across North America.
Physical tests include extreme conditions like live wire cutting to optimize hazard detection.
Combines solar-powered, ruggedized sensors with a cloud-independent analytics system.

Culture + Values

Passion, innovation, and technology align to modernize the power grid.
Pioneering ‘Active Grid Response’—immediate detection, precise localization, detailed identification, outage monitoring.
Developed in partnership with utilities—focused on working alongside linemen.
Built by a lineman for linemen—understands the rigor and commitment required in the field.
Relentlessly committed to giving crews the right tools to get the job done.

Environment + Sustainability

1,000+ miles & 10K+ poles

Gridscope Deployment Scale

Expanded Gridscope sensor deployment covers over 1,000 miles of power lines and 10,000 poles, enhancing wildfire risk mitigation efforts across multiple states.

70% Outage Reduction

Improved Grid Reliability

Gridscope technology has been shown to significantly reduce outage durations by over 70%, enhancing power grid stability and wildfire prevention.

Technology deployed across five U.S. states to reduce wildfire risk via early detection of vegetation and fallen-line hazards.
Continuous environmental stressor measurement (e.g., vibrations from falling branches) enables predictive maintenance and environmental hazard mitigation.
