Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Electronics Engineering, or related technical field (equivalent experience considered).
• 3+ years of professional embedded software/firmware experience.
• Strong proficiency in C and C++, memory management and data structures for constrained systems.
• Hands-on experience with bare-metal and RTOS firmware; ARM microcontrollers preferred.
• Knowledge of microcontroller peripherals, interrupts, DMA, timers, and boot processes.
• Experience with embedded Linux systems: processes, threads, I/O, cross-compilation, CLI.
• Experience with embedded comms: SPI, I2C, UART, CAN, USB, Ethernet; TCP/IP/UDP.
• Familiarity with debugging tools (GDB, JTAG/SWD, oscilloscopes).
• Ability to read schematics, datasheets, and interface docs for hardware/software integration.
• Experience with Git-based workflows, builds (CMake/Make), and documentation.

Responsibilities

• Design and develop embedded software and firmware for high-performance, real-time systems.
• Implement new functionality for unmanned systems control, telemetry, video, and navigation.
• Develop and maintain drivers, HALs, BSPs and interfaces for sensors, radios, payloads, and peripherals.
• Integrate software with hardware and third-party systems including flight controllers and SDKs.
• Develop communication interfaces and protocols (SPI, I2C, UART, CAN, USB, Ethernet, IP).
• Optimize software for latency, resource use, and power consumption.
• Create and execute unit, integration, bench, and system tests; analyze telemetry.
• Troubleshoot complex issues across software, hardware, and system layers; root-cause analysis.
• Collaborate with hardware, software, product, and test teams to deliver robust solutions.
