Embedded Software Engineer (FreeRTOS)

Job Title: Embedded Software Engineer – FreeRTOS & Space Systems

Company: Harpy Aerospace
Location: (Inperson + Lab Integration Support)
Job Type: Full-Time / Contract / Internship
Start Date: Immediate

About the Role

Harpy Aerospace is developing next-generation CubeSat platforms and autonomous payload systems for Low Earth Orbit (LEO) missions. We are seeking an Embedded Software Engineer with strong expertise in FreeRTOS, bare-metal programming, and real-time microcontroller systems to join our avionics and satellite systems team.

This role focuses on developing firmware for space-grade flight computers, power systems, and payload controllers, ensuring reliable operation under extreme conditions with deterministic task execution.

Core Responsibilities

• Design, develop, and maintain FreeRTOS-based embedded firmware for ARM Cortex-M (STM32, LPC, ESP32, etc.)
• Implement real-time task scheduling for:
• Sensor data acquisition
• Power management
• Communication subsystems (UHF/VHF, LoRa, AX.25)
• Deployment control logic (e.g., burnwire)
• Optimize memory and CPU usage under CubeSat constraints (low power, limited RAM/Flash)
• Implement low-level drivers for:
• I²C, SPI, UART, GPIO, ADC, RTC
• External sensors (radiation, temperature, inertial, GPS)
• Ensure robust error handling, fault detection, and watchdog reset logic
• Write clean, modular, version-controlled C/C++ code with documentation
• Support Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) testing frameworks
• Contribute to flight software validation and ground station interface integration
• Maintain interface with ground operations team for uplink/downlink command handling

Required Skills

• Proficiency in C/C++ for embedded systems
• Strong experience with FreeRTOS or other RTOS platforms
• Familiarity with STM32CubeMX or PlatformIO development environments
• Experience with embedded debugging tools (e.g., JTAG/SWD, UART serial terminals, logic analyzers)
• Understanding of embedded state machines, ISR handling, and real-time task priorities

Bonus Skills

• Experience with:
• AX.25, LoRa, or other amateur/low-data-rate protocols
• custom telemetry stacks
• CubeSat EPS and OBC subsystems
• Python or Bash scripting for test automation or telemetry decoding
• Familiarity with radiation-tolerant embedded design or ECSS-compliant software practices

Eligibility

• B.E. / B.Tech / M.E. / M.Tech in ECE, Embedded Systems, Aerospace, or CS with embedded focus
• PhD candidates or experienced researchers in flight software, autonomous systems, or RT embedded design are also encouraged
• Prior CubeSat/CanSat/HAB project experience is a significant plus

What We Offer

• Work on real CubeSat missions flying in LEO
• Exposure to the full spacecraft lifecycle: design, integration, flight, and operations
• Pathway to contribute to mission control, flight software, and payload automation
• Performance-based growth into long-term roles on flagship missions
• Certification, LORs, and publication opportunities for research-aligned work
