Sdr Software Engineer Jobs (NOW HIRING)

WIRELESS FIRMWARE ENGINEER (STARLINK MOBILE) 

The Starlink Mobile 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 is a unique position which will work closely with both wireless systems engineers and protocol firmware engineers to accelerate wireless PHY development and find solutions to interdisciplinary challenges. The ideal candidate will be equally 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: 

• Bachelor's degree in computer science, computer engineering, electrical engineering or a STEM discipline. 
• 1+ Years of experience with at least 1 of the following; wireless signal processing, wireless communications, modem systems design, wireless systems engineering, DSP (digital signal processing), or physical layer processing (L1).
• 1+ 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. 
• SDR (software defined radio) experience.
• 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 as needed.

COMPENSATION AND BENEFITS:

Pay range:    
Software Engineer/Level I: $135,000.00 - $155,000.00/per year    
Software Engineer/Level II: $155,000.00 - $185,000.00/per year    
Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: 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, short and long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year. Employees accrue paid sick leave pursuant to Company policy which satisfies or exceeds the accrual, carryover, and use requirements of the law.
