Senior Firmware Engineer

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.

Must-Have Qualifications (Quick Screen)

• Experience:
  
  5+ years of embedded firmware development and 3+ years of hands-on IoT systems experience.
• Core
  
  Languages:
  
  Mastery of C/C++ for embedded systems and Python for tooling.
• Hardware & OS:
  Deep experience with ARM Cortex-M, STM
  32, or Microchip platforms, plus hands-on experience with RTOS (FreeRTOS/Zephyr) and embedded Linux systems via Buildroot.
• Hardware Interfaces:
  Ethernet, USB, SPI, I2C, UART, RS-485.
• Tools:
  Git, JTAG, SWD, oscilloscopes, and logic analyzers.
• The Intangibles: A collaborative team player with recent, hands-on experience integrating AI coding assistants into their daily development workflow over the last year. Comfortable navigating both new product introduction (NPI) and mature, legacy codebases.

What You Will Do

• 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.

Benefits

• Mission-Driven: A rewarding career directly combating climate change.
• Growth Industry: Stable, well-funded company in the booming green-tech and utility tech sectors.
• Comprehensive Benefits:
  Competitive pay, full health/wellness coverage, and 401(k).
