Description
An Embedded Software Developer VA builds firmware and low-level software for connected devices, microcontrollers, sensors and industrial systems. They can develop device drivers, communication protocols, real-time logic and firmware update systems while working closely with hardware engineers. Outsource Teams provides top 1% vetted talent with experience developing software for shipped hardware products, no lock-in contracts and a replacement guarantee.
Responsibilities
- Develop firmware in C and C++ for microcontrollers such as ARM Cortex-M, ESP32, STM32 and Nordic platforms.
- Work with RTOS environments like FreeRTOS or Zephyr and with embedded Linux where the product needs it.
- Implement device drivers and communication protocols including I2C, SPI, UART, CAN, BLE, Wi-Fi and MQTT.
- Design for low power, limited memory and real-time deadlines, and measure the results.
- Build secure boot, over-the-air firmware update and device provisioning mechanisms.
- Debug at the hardware level with oscilloscopes, logic analysers and JTAG or SWD debuggers.
- Write unit and hardware-in-the-loop tests and maintain CI for firmware builds.
- Collaborate with hardware engineers on schematics, bring-up and design-for-test.
- Document firmware architecture, interfaces and release notes for manufacturing and support teams.
Software & Tools
Requirements
- At least 5 years of embedded software development with shipped hardware products.
- Expert C and solid C++, with experience on ARM Cortex-M microcontrollers and at least one RTOS.
- Hands-on with common peripherals and protocols (SPI, I2C, UART, CAN, BLE, MQTT) and with reading schematics and datasheets.
- Experience with embedded Linux, Yocto or Buildroot is a strong advantage.
- Familiarity with Git, CI for firmware, static analysis and coding standards such as MISRA C.
- Degree in electronics, computer or electrical engineering, or an equivalent record of shipped devices.
