Embedded Firmware Engineer - Smart Devices & IoT

Embedded Firmware Engineer - Smart Devices & IoT

Build the brains behind the next generation of smart lighting.

At WAC, we're creating connected products that bring together embedded systems, wireless communication, cloud services, and great user experiences. We're looking for a Firmware Engineer who loves solving real-world problems and wants to help build products that ship to customers around the world.

This is more than writing code. You'll work at the intersection of hardware, software, manufacturing, and IoT-developing firmware that powers smart lighting systems used in commercial and residential environments.

What You'll Do

• Design and develop embedded firmware for next-generation connected devices.
• Work with Bluetooth, Wi-Fi, Thread, DALI, DMX, and other communication technologies.
• Debug challenging hardware and software issues using real engineering tools-not just simulations.
• Collaborate with hardware, mobile, cloud, QA, and manufacturing teams to bring products from concept to production.
• Help build secure, reliable products with OTA updates, device provisioning, and modern IoT connectivity.
• Contribute ideas, improve products, and take increasing ownership as you grow.

We're Looking For Someone Who

• Loves building things and figuring out how they work.
• Is curious, humble, and always learning.
• Takes initiative and enjoys solving difficult technical problems.
• Wants to see their work shipped into real products used every day.
• Thrives in a fast-moving environment where great ideas can come from anyone.

You'll Bring

• BS in Electrical Engineering, Computer Engineering, Computer Science, or equivalent industry experience.
• Minimum 5 years of experience in embedded firmware engineering, or equivalent hands-on project experience for exceptional candidates.
• Working proficiency in C/C++ for resource-constrained embedded systems.
• Experience with 32-bit ARM microcontrollers and common embedded development/debugging workflows.
• Familiarity with in-circuit debugging techniques using JTAG, SWD, serial consoles, and related tools.
• Working knowledge of hardware communication protocols such as SPI, UART, I2C, BLE/Mesh, DMX, DALI, Wi-Fi, or similar technologies.
• Hands-on lab experience with hardware bring-up, prototyping, and debugging using oscilloscopes, logic analyzers, protocol analyzers, or similar instrumentation.
• Basic proficiency in scripting languages such as Python or Bash for automation, tooling, and test support.
• Experience with software configuration and issue management tools such as Git and Jira.
• Understanding of design for manufacturability, testability, reliability, and cost is preferred.
• Experience supporting product validation, manufacturing test, or production troubleshooting is preferred.
• Strong technical documentation, written communication, and verbal communication skills.
• Ability to follow structured engineering processes while applying creative problem-solving to technical challenges.
• Willingness and ability to travel domestically and internationally as required.
• Ability to collaborate with third-party development partners and external engineering teams is preferred.
• Mandarin language proficiency is a plus.
