SPACE EXPLORATION TECHNOLOGIES CORP
Sr. Wireless Firmware Engineer (Direct To Cell)
SPACE EXPLORATION TECHNOLOGIES CORP, Redmond, Washington, United States, 98052
Overview
Sr. Wireless Firmware Engineer (Direct To Cell) Redmond, WA 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. SR. WIRELESS FIRMWARE ENGINEER (DIRECT TO CELL) The direct-to-cell program is working to provide global cellular connectivity from space. As a wireless firmware engineer, you will play a critical role in developing novel wireless signal processing algorithms, implementing optimized software for use on satellites and ground stations, debugging complex systems and performance issues, and developing production software. This position will work closely with both wireless systems engineers and protocol firmware engineers to accelerate wireless PHY development and solve interdisciplinary challenges. The ideal candidate will be comfortable with wireless signal processing algorithms and high-performance software development. 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. Basic Qualifications
Masters or PhD degree in computer science, computer engineering, electrical engineering or a STEM discipline. 5+ years of experience with wireless signal processing, wireless communications, modem systems design, wireless systems engineering, DSP, or physical layer processing (L1). 5+ years of C/C++ or Matlab 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 debugging and performance optimization skills; excellent analytical 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
Pay range: Software Engineer /Senior: $160,000.00 - $220,000.00 per year Your actual level and base salary will be determined on a case-by-case basis and may vary based on job-related knowledge and skills, education, and experience. Base salary is just one part of your total rewards package at SpaceX. You may also be eligible for long-term incentives, in the form of company stock, stock options, or long-term cash awards, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, disability and life insurance, paid parental leave, and various other discounts and perks. You may accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year. Exempt employees are eligible for 5 days of sick leave per year. To conform to U.S. Government export regulations, applicant must be a U.S. citizen or national, U.S. lawful permanent resident (green card holder), refugee under 8 U.S.C. 1157, or asylee under 8 U.S.C. 1158, or be eligible to obtain the required authorizations from the U.S. Department of State. SpaceX is an Equal Opportunity Employer; employment with SpaceX is governed on the basis of merit, competence and qualifications and will not be influenced by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, or any other legally protected status.
