Firmware Engineer, Embedded Systems

The role

You will develop embedded software for connected environmental sensing systems. You will work with electrical engineers to bring up hardware, integrate sensors, and manage firmware from prototype to production.

What you will do

• Develop low-level firmware for microcontrollers.
• Build reusable device drivers and integrate system-level features.
• Bring up new hardware and integrate analog and digital sensors.
• Troubleshoot issues across electrical, firmware, and software boundaries.
• Collaborate with electrical engineering on microcontroller and peripheral selection, schematic reviews, and hardware/firmware interfaces.
• Develop device connectivity, low-power operation, remote configuration, and over-the-air firmware updates.
• Build and maintain device flashing, provisioning, and manufacturing test workflows.
• Own firmware development from prototype through production and field support.

Required qualifications

• 3+ years of firmware or embedded systems development experience on microcontrollers and various SoCs.
• Bachelor’s degree in a related field.
• Strong embedded C/C++ programming skills.
• Experience with bare-metal and RTOS environments and creating custom sensor libraries.
• Solid understanding of firmware design and programming best practices.
• Extensive experience using hardware debugging tools including JTAG, SWD, trace probes, and digital logic probes and oscilloscopes.
• Experience with common embedded interfaces and protocols such as SPI, I2C, UART, USB, CAN, or Ethernet.
• Experience developing firmware for IoT devices (WiFi, BLE, LoRaWAN, Zigbee, etc.) including OTA updates, remote configuration, and reliable fleet operation.
• Experience with low-power or battery-operated devices and embedded security principles.
• Familiarity with bringing products into production, including device provisioning, manufacturing testing, or firmware version control and distribution.
• Familiarity with the PCB design process and common electrical prototyping tools such as soldering, reworking, reflow, and assembly.
• Comfortable with cross-domain collaboration with hardware, mechanical, and software engineers.

Nice to have

• Experience at an early-stage startup or building independent projects
