Job Summary
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 ofenabling 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 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:
- Bachelors Masters or PhD degree in computer science computer engineering electrical engineering or a STEM discipline.
- 5 Years of experience with at least 1 of the following: wireless signal processing modem systems design wireless systems engineering DSP (digital signal processing) or physical layer processing (L1).
- 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.
- 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.
