Job Description:

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.

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 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.
Job Requirements:

BASIC QUALIFICATIONS:

  • Master’s or PhD degree in computer science, computer engineering, electrical engineering or a STEM discipline.
  • 1+ Years of experience with; 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++ 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.
  • 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 and weekends as needed.

COMPENSATION AND BENEFITS:

Pay range:
Software Engineer/Level I: $130,000.00 - $155,000.00/per year
Software Engineer/Level II: $150,000.00 - $180,000.00/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 & long-term disability insurance, life insurance, paid parental leave, and various other discounts and perks. You may also accrue 3 weeks of paid vacation & will be eligible for 10 or more paid holidays per year. Exempt employees are eligible for 5 days of sick leave per year.

ITAR REQUIREMENTS:

SpaceX builds rockets and spacecraft from the ground up; including electronics, software, vehicle structures, and engines. In-house development includes nearly all flight critical custom components amounting to approximately 85% of our vehicles both ...

Benefits:
SpaceX offers one of the best environments in the world for employees to learn, build real working systems and tackle exciting challenges every day. We operate in a fun, casual work environment and have great benefits including: competitive salary, stock options, medical/dental insurance and free gym memberships. By joining the SpaceX team, you are not just a part of history, you are making it.

Supported Manufacturers:
Established in 2002 by Elon Musk, the founder of PayPal and the Zip2 Corporation, SpaceX has already developed two brand new launch vehicles, established an impressive launch manifest, and been awarded COTS funding by NASA to demonstrate delivery and return of cargo to the International Space Station. Supported by this order book and Mr. Musk‘s substantial resources, SpaceX is on an extremely sound financial footing as we move towards volume commercial launches.

Supported Models:
With the Falcon 1, Falcon 9 and Falcon Heavy launch vehicles, SpaceX is able to offer a full spectrum of light, medium and heavy lift launch capabilities to our customers. We are able to deliver spacecraft into any inclination and altitude, from low Earth orbit to geosynchronous orbit to planetary missions. The Falcon 9 and Falcon Heavy are the only US launch vehicles with true engine out reliability. They are also designed such that all stages are reusable, making them the world‘s first fully reusable launch vehicles. And our Dragon crew and cargo capsule, currently under development, will revolutionize access to space by providing efficient and reliable transport of crew and cargo to the ISS and other LEO destinations.
