Sr. RF Software Engineer, Customer Hardware (Starlink)

As a Sr. RF Software Engineer at SpaceX, your primary responsibilities will include developing RF-focused functionality and calibration/test software for wireless hardware operation. You will design and automate RF test setups and closely collaborate with engineers from various fields to validate RF systems, ensuring high performance for our innovative Starlink technology.

To qualify for the Sr. RF Software Engineer role at SpaceX, you need a bachelor's degree in electrical engineering, physics, or computer science, alongside 5 or more years of experience with C#, C/C++, or Python, and RF test equipment. A master's degree and familiarity with SOLID design principles, RF communication concepts, and both Windows and Linux operating systems are beneficial.

The work environment for a Sr. RF Software Engineer at SpaceX is highly collaborative and fast-paced. You’ll be tackling unsolved problems, iterating rapidly from design to demo, and working on real-world challenges that have the potential to impact communities worldwide, filling your workdays with excitement and innovation.

In this position, you'll have hands-on experience with various RF testing equipment including vector network analyzers, spectrum analyzers, RF power meters, high-speed oscilloscopes, and more. Your expertise will be essential for validating the performance of our revolutionary satellite technology.

The Sr. RF Software Engineer role at SpaceX is typically in-office to facilitate collaboration and rapid iterations, critical in our dynamic environment. Flexibility in work hours may be necessary, with extended hours and weekends occasionally required to meet project demands.

When developing RF software for Starlink systems, I would focus on understanding the requirements of our end-users, ensuring robust functionality through simulation and testing. Implementing agile methodologies would be key to iterating effectively, while maintaining close collaboration with other engineering domains to align on design and validation processes.

I have extensive experience working with RF testing equipment, including vector network analyzers and spectrum analyzers. I am proficient in setting up automated test systems, conducting thorough characterizations of RF designs, and interpreting measurements to ensure the highest level of performance for wireless hardware.

I prioritize tasks by assessing the project's impact and timeline while aligning with team goals. I use project management tools to track progress, delegate key responsibilities where needed, and maintain consistent communication with team members to ensure all projects move forward within their timelines.

My approach to troubleshooting involves isolating variables to pinpoint the issue, analyzing logs, running diagnostics, and consulting with team members. A systemic, methodical approach is essential, involving both hardware and software examinations to ensure comprehensive solutions.

I adhere to crucial RF principles such as understanding S-parameters, maximizing gain and linearity, and ensuring proper input/output matching. Staying updated with the latest RF technologies and methodologies is essential to maintain high standards in RF communication systems.

I evaluate the success of an RF software project based on performance metrics, user feedback, and alignment with project goals. Ensuring that deliverables meet specified requirements and maintain system reliability while facilitating user experience is crucial in my assessment.

In a previous role, I faced a challenge with RF signal integrity under varying environmental conditions. Through rigorous testing, along with collaboration with hardware teams, I developed a software calibration process that adapted in real-time, significantly improving signal stability and performance.

I utilize tools such as Git for version control, ensuring proper code management and collaboration. For configuration management, I rely on software like Ansible or Puppet, which helps maintain environment consistency and compliance across various development stages.

I implement best coding practices by adhering to SOLID principles, ensuring code readability, and conducting thorough unit tests. Regular code reviews and constructive feedback sessions with the team also help maintain high-quality standards throughout the development process.

I stay updated with advancements in RF engineering through continuous learning. I actively participate in industry conferences, such as IEEE events, subscribe to professional journals, engage in relevant online courses, and collaborate with peers to share insights and knowledge.
