Job description

Sr. Wireless Firmware Engineer (Starlink Mobile)

Sunnyvale, CA

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.

Responsibilities

• Design and implement physical layer (PHY) algorithms for satellite-based 4G/5G (LTE/NR) eNodeB/gNodeB.
• Develop optimized signal processing algorithms running on resource-constrained CPUs.
• Develop models and run simulations to analyze and validate overall system performance, including modem performance.
• Design, implement, test, maintain, and document the wireless PHY and MAC layers of the protocol stack.
• Identify and debug complex performance issues across the wireless PHY and MAC layers.
• Participate in architecture, design, and code reviews. Contribute to system dimensioning and algorithm design for next generation hardware.

• 5+ Years of C/C++ coding experience.

Preferred Skills and Experience

• Familiarity with 3GPP 4G/5G (LTE/NR) physical layer design or other modern broadband OFDM waveforms such as WiMAX, 802.11 WiFi, DVB-S2, DVB-C, 5G NTN (non-terrestrial networks).
• Familiarity with forward error correction (FEC) coding concepts.
• Basic familiarity with MAC layer (medium access control, L2).
• Development and optimization of complex signal processing algorithms in both fixed and floating point.
• Familiarity with Linux command line use, git-based version control, and python programming.
• Experience supporting products through the full release cycle including commercial deployment.
• Strong skills in debugging and performance optimization; exceptional analytical skills and engineering fundamentals.
• Excellent verbal and written communication skills.
• Ability to work effectively in a dynamic environment with changing needs and requirements.

Additional Requirements

• Must be willing to work extended hours and weekends as needed.

Compensation and Benefits

• To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
