Experience Level

Senior-level (Principal). No explicit years-of-experience specified.

Responsibilities

Primary technical and leadership responsibilities include:

• Lead design, development, and optimization of software for satellite communication and signal processing systems.
• Define software architecture and system design to meet project performance and reliability requirements.
• Integrate software components with hardware, RF frontends, and communication subsystems with systems engineers.
• Perform code reviews, provide technical guidance, and mentor junior engineers.
• Conduct testing, validation, and verification to ensure software reliability in space environments.
• Troubleshoot and resolve complex software issues in development and deployed systems.
• Maintain documentation of designs, development processes, and test results.
• Monitor industry trends and apply relevant best practices for space application software.

Requirements

Core technical must-have skills and experience; followed by common nice-to-have items.

Must-have:

• Proven experience developing software for embedded systems, ideally for satellite communication or other space applications.
• Proficiency in C/C++ and strong software architecture and design skills.
• Experience with real-time operating systems (RTOS) and embedded Linux user-space stacks.
• Experience with software-defined radios (SDRs) and FPGA programming.
• Familiarity with software verification and validation processes and agile development methodologies.
• Experience with Yocto or Buildroot for embedded Linux builds.
• Strong problem-solving, communication, and teamwork abilities.
