Senior Firmware Engineer - Remote!

• Hands-on Development: Design, implement, and optimize efficient, reliable real-time firmware for microcontroller-based IoT devices in resource-constrained environments.
• Team Collaboration: Act as a collaborative senior presence on the team, working closely with hardware, software, and QA engineers to define interfaces and system architectures.
• AI Workflow Integration: Champion the use of modern AI development tools within your daily workflow to accelerate coding, debugging, and testing performance.
• IoT Stack Integration: Connect device data into cloud and application layers via MQTT or HTTP/HTTPS, and manage OTA firmware update pipelines.
• Test & Debug: Troubleshoot complex firmware and hardware issues using JTAG/SWD, oscilloscopes, and logic analyzers.

Preferred (Plus) Skills

• Wireless tech and protocols (Wi-Fi, BLE, Cellular, LoRaWAN, TCP/IP, Modbus).
• Embedded GUI development (LVGL, TouchGFX).
• Experience with Erlang BEAM, Embedded Elixir, and Nerves.
• Background in energy management or building automation systems.

Are you a Senior Firmware Engineer who loves being deeply hands-on but is ready to act as a collaborative technical anchor for an engineering team? We are looking for a senior-level engineer who excels at leading by example through exceptional code contribution rather than administrative people management. If you are a team player who has spent the last year leveraging AI development tools to optimize workflows and want to help accelerate the transition to a sustainable energy future, this is your next move.
