Firmware Engineer

Hydrosat is seeking a dedicated firmware engineer to support the development of embedded software for space-based payloads and ground support systems. This role focuses on low-level software that enables reliable communication, control, and data handling between hardware components in flight and test environments.

Responsibilities:

• Design, implement, and test firmware for microcontrollers and embedded systems used in space payloads and ground support equipment (GSE)

• Develop low-level drivers, communication protocols, and control logic for sensors, actuators, and power systems

• Collaborate with electrical, software, and systems engineers to ensure seamless integration between firmware and hardware

• Support hardware bring-up, debugging, and validation using lab equipment (oscilloscopes, logic analyzers, etc.)

• Participate in requirements development, interface definition, and verification planning

• Contribute to firmware configuration management, version control, and documentation

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field; Master’s preferred

• 10+ years of experience in embedded firmware development for high-reliability or mission-critical systems

• Proficiency in C/C++ for embedded systems and familiarity with real-time operating systems (RTOS)

• Experience with microcontroller platforms (e.g., STM32, TI, Microchip) and hardware interfaces (SPI, I2C, UART, CAN)

• Strong debugging skills and experience with lab tools for hardware/software integration

Preferred Experience:

• Experience with firmware for spaceflight or aerospace systems

• Familiarity with FPGA-based systems and HDL (e.g., VHDL or Verilog) is a plus

• Exposure to NASA or industry standards such as:,NASA-STD-8739.8 (Software Assurance Standard),NASA-HDBK-4008 (Programmable Logic Devices Handbook), ECSS-E-ST-40C (Software Engineering for space systems)

• Experience with Git, CI/CD pipelines, and automated test frameworks
