Description For Sr. Wireless Firmware Engineer (Direct to Cell)

SpaceX, a pioneering space exploration company, is seeking a Senior Wireless Firmware Engineer for their groundbreaking direct-to-cell program. This role sits at the intersection of space technology and global telecommunications, working to provide worldwide cellular connectivity from space.

The position offers a unique opportunity to work on cutting-edge technology that will revolutionize global communications. As a Sr. Wireless Firmware Engineer, you'll be responsible for developing novel wireless signal processing algorithms and implementing optimized software for both satellites and ground stations. You'll work closely with wireless systems engineers and protocol firmware engineers to accelerate wireless PHY development and solve complex interdisciplinary challenges.

The ideal candidate should have a strong background in both wireless signal processing algorithms and high-performance software development. The role requires expertise in physical layer (PHY) algorithms for satellite-based 4G/5G systems, optimization of signal processing algorithms, and development of models for system performance analysis.

SpaceX offers a competitive compensation package starting from $160,000 to $220,000 per year, complemented by attractive benefits including equity options, comprehensive healthcare, and retirement plans. The company culture is fast-paced and mission-driven, focused on achieving the ambitious goal of enabling human life on Mars.

Working at SpaceX means being part of a team that's pushing the boundaries of what's possible in space technology. The company's commitment to innovation and excellence provides an environment where your work will directly contribute to advancing human space exploration and global connectivity.

This role requires a minimum of 5 years of experience and an advanced degree in a relevant field. Due to ITAR requirements, candidates must be U.S. citizens, permanent residents, or have eligible immigration status. The position demands technical excellence, creative problem-solving abilities, and the willingness to work extended hours when needed to meet mission-critical deadlines.
