## Description

The Senior Software Engineer will design and develop embedded firmware for the GridPoint Energy Management Platform, working across base firmware, application firmware, and supporting tooling. This role pairs deep embedded C/C++ development with the breadth to integrate devices across the wireless and cloud layers of the IoT stack.
Working alongside hardware, firmware, and QA engineers, the Senior Software Engineer is responsible for architecting, developing, testing, and delivering quality firmware for microcontroller-based products built on platforms such as Microchip and STMicro. These products provide the foundational telemetry and controls that optimize our customers' energy profile. The scope covers both new product introduction (NPI) and sustaining of existing products., Firmware Development & Design

 * Design and implement efficient, reliable firmware for microcontroller-based IoT devices

 * Develop real-time embedded software in C/C++ for resource-constrained environments

 * Create and maintain device drivers for sensors, actuators, and communication modules

 * Implement power management strategies for battery-operated devices

 * Optimize code for memory usage, performance, and power consumption

 * Develop firmware for new product introduction (NPI) as well as sustaining of legacy products

Platform & Integration

 * Integrate device data into cloud and application layers via MQTT, HTTP/HTTPS, or similar protocols

 * Develop and maintain device management, OTA firmware update, and telemetry pipelines

 * Collaborate with application and cloud engineers on protocol design, data modeling, and interface contracts between embedded and platform layers

 * Contribute to wired and wireless platform architecture decisions

Test, Debug & Engineering Excellence

 * Create comprehensive test plans and perform unit, integration, and system testing

 * Debug firmware issues using oscilloscopes, logic analyzers, and JTAG/SWD debuggers

 * Conduct performance analysis and optimization of embedded systems

 * Define and document interfaces, protocol specifications, and test plans

 * Collaborate with hardware engineers on system architecture and component selection
