Firmware Engineer
Lighting & Environmental Controls

Our Lighting Group is growing, and we re looking for a Firmware Engineer to dive in and help us build the next generation of our lighting and environmental control products. This role requires your presence at our Rockleigh campus for at least 3 days a week to facilitate hands-on testing and collaboration. If you enjoy tackling complex embedded challenges and want to see your work directly impact innovative products like advanced thermostats, keypads, smart shades, and system controllers, this is for you.

We need an engineer who isn t afraid to get their hands dirty, solve tough problems, and can work independently and collaborate effectively to get things done.

You ll be a key player in our firmware development team, at first learning from our subject matter experts, then taking ownership of the complete firmware lifecycle for new and existing products. This means:

• Helping to review and revise product requirements to ensure technical feasibility and clarity from a firmware perspective.
• Designing, developing, and debugging firmware for our embedded systems, focusing on our Lighting and Environmental product lines (primarily thermostats, keypads, shades, and controllers).
• Collaborating closely with hardware engineers and other developers to integrate firmware and troubleshoot system-level issues.
• Assisting hardware engineers with new board bring-up
  , then taking the lead on implementing and running firmware-centric design verification tests (DVT) and performing real-time debugging.
• Creating clear technical documentation including design specifications and test procedures.
• Supporting the products you help create
  , ensuring they meet our quality standards and customer expectations.

We re looking for someone who can be productive quickly. You ll need:

• At least 3 years of hands-on embedded firmware development experience
  , covering all phases from initial board bring-up support and DVT to real-time debugging and system testing.
• Strong C/C++ programming skills and a deep understanding of microcontroller architectures.
• Proven ability to diagnose and solve complex system-level problems
  .
• Good communication skills
  – you can explain technical concepts clearly, both verbally and in writing.
• A proactive, self-motivated approach with a commitment to delivering quality work. You thrive in a team and can adapt to a fast-paced development cycle.

These skills aren t mandatory, but they ll help you make an even bigger impact:

• Control Theory (e.g., PID controllers, loop filters)
• Real-Time Operating Systems (RTOS) – Free RTOS is a significant plus.
• Communication protocols such as Ethernet, Bluetooth (BLE), 802.15.4/Mesh (e.g., Zigbee, Thread).
• Modern embedded security protocols and best practices.
• Lighting control systems and DALI technology.
• Common peripheral interfaces like UART, I2C, SPI, and USB
