Company Overview
We are a rapidly growing technology startup focused on delivering next-generation drones for security and safety applications. Our company vertically integrates hardware and software to create leading edge capabilities in the UAV space, with a focus on saving lives.

We are looking for a Firmware Engineer to design, develop, and maintain embedded firmware for products based on STM32 microcontrollers. You will work close to the hardware, implementing low-level drivers, real-time functionality, and reliable embedded systems used in production devices.

Responsibilities

  • Design, develop, and maintain firmware for STM32 microcontrollers

  • Develop motor controller/ESC algorithms for our various products

  • Implement and debug low-level drivers (GPIO, UART, SPI, I2C, CAN, USB, ADC, timers, DMA)

  • Develop firmware using C/C++ (bare-metal and/or RTOS environments)

  • Work with STM32 HAL/LL, CMSIS, and vendor toolchains

  • Integrate firmware with hardware designs and collaborate closely with hardware engineers

  • Debug and troubleshoot issues using tools such as JTAG/SWD, logic analyzers, oscilloscopes

  • Optimize firmware for performance, memory usage, and power consumption

  • Participate in code reviews and follow best practices for embedded software development

  • Write and maintain technical documentation

  • Support manufacturing, testing, and field issues as needed

Required Qualifications

  • Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience

  • Experience with AC/BLDC motor control algorithms

  • Strong experience developing firmware for STM32 microcontrollers

  • Proficiency in embedded C/C++

  • Solid understanding of microcontroller architectures, peripherals, and datasheets

  • Experience with bare-metal development and/or RTOS (FreeRTOS or similar)

  • Familiarity with debugging embedded systems using JTAG/SWD

  • Experience using Git or other version control systems

Preferred Qualifications

  • Experience with FreeRTOS or other real-time operating systems

  • Knowledge of low-power design techniques

  • Experience with bootloaders and firmware update mechanisms

  • Familiarity with communication protocols (CAN, Ethernet, USB)

  • Experience bringing up new hardware revisions

  • Exposure to automated testing or CI for embedded systems

Nice to Have

  • Experience with other MCU families (NXP, Nordic, Microchip, TI)

  • Basic understanding of hardware schematics

  • Experience with safety-critical or regulated products

  • Knowledge of embedded security concepts (secure boot, firmware signing)

What We Offer

  • Opportunity to work on real-world embedded products

  • Collaborative environment with hardware and systems engineers

  • Competitive compensation and benefits

  • Room for technical growth and ownership
