• Work with communication protocols to control and integrate peripheral devices.
• Perform testing and debugging, both in the lab and at customer sites.
• Collaborate with cross-functional teams to refine requirements and implement features.
• Occasionally support system integration and deployment of hardware/software stacks.

• Contribute to technical documentation and version control (Git).
• Support team knowledge sharing and mentor less-experienced developers when appropriate.
  
  Experience in hands-on software development.
• Strong proficiency in C++ and/or Python.
• Experience coding for embedded systems (e.g., ESP32, ARM Cortex-based boards).
• Familiarity with low-level hardware interfacing, including serial comms, GPIO, USB, or SPI/I2C.
• Comfort working in Linux development environments.
• Strong problem-solving skills and attention to detail.
• Ability to adapt quickly to new hardware, tools, and use cases.
• Familiarity with unit testing, debugging tools, and Git-based workflows.
Desirable:
• Experience with security-focused projects (e.g., Government, MoD).
• Exposure to cryptography and secure audio/data transport.
• Knowledge of Bluetooth, Ultra-Wideband, or other wireless protocols.
• Familiarity with USB device drivers or USB communication.
