Role summary

SpaceX is seeking a DSP Engineer for its Starlink Space Lasers team to develop cutting-edge satellite free-space optical communication systems. This role involves designing and testing algorithms, modeling system performance, and collaborating with cross-functional engineering teams. The engineer will contribute to mission-critical applications in low earth orbit and beyond, working in a fast-paced, collaborative environment. Responsibilities include driving firmware/software design decisions, researching novel solutions, and owning product results from requirements to flight. A Bachelor's degree in CS, CE, or EE with 1+ years of DSP experience, or 3+ years of DSP experience in lieu of a degree, is required, along with experience in modem design, algorithm development, and system modeling.

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.

DSP ENGINEER, SATELLITES (STARLINK)

The Starlink Space Lasers team develops, produces, and deploys the most cutting-edge satellite free-space optical communication systems in the world. We are looking for engineers to contribute to the development of laser communications terminals and imaging products for the groundbreaking constellation of Starlink satellites. All SpaceX optical systems (laser communication terminal and other optical products) require a blend of theoretical expertise, practical implementation skills, and a passion for solving complex problems in real-time, resource-constrained systems.

As a DSP engineer on the Starlink Space Laser team, you will work with a team of Optical engineers, DSP engineers, software engineers, hardware engineers and end users to shape the future of laser communication systems and directly contribute to mission-critical applications in low earth orbit and beyond. You will work in a highly collaborative and fast-paced environment.

RESPONSIBILITIES:

Drive program-level decisions on firmware and software designs

Research novel solutions for large-scale, long-distance free space and fiber optic communication systems

Design and test algorithms for on-orbit and ground-based data processing

Work in close collaboration with FPGA, RF/antenna, and software engineers to design and validate communication systems

Perform on-orbit demonstrations and testing

System-level and link-level design in support of spacecraft communications and sensing systems

Develop floating-point and fixed-point models and run simulations to analyze and validate overall system performance, including modem performance

Own the end-to-end results of your products, from requirements gathering through production and flight, including verification and documentation

BASIC QUALIFICATIONS:

Bachelor’s degree in computer science, computer engineering or electrical engineering and 1+ years of experience in digital signal processing engineering; or 3+ years of professional digital signal processing engineering experience in lieu of a degree

1+ years of experience designing and verifying modems and sensors

1+ years of experience developing signal processing algorithms in Python, Matlab, or C/C++

1+ years of experience in system-level modeling and/or digital signal processing

PREFERRED SKILLS AND EXPERIENCE:

Master’s degree in electrical engineering with emphasis in communication systems or digital signal processing

Expertise modeling with both floating-point and fixed-point signal processing algorithms in Python, Matlab, or C/C++

Experience in coherent digital demodulation of waveforms such as GMSK, BPSK, QPSK, QAM, PCM/FM, APSK, OFDM, including spread spectrum

Experience developing firmware for Xilinx FPGA platforms using the Xilinx toolchain, or STM32

Experience with verification between simulation and RTL FPGA implementation

Experience modeling RF and Optical and channel impairments such as multipath, phase noise, group delay, fading and nonlinear distortion

Understanding of RF and Optical concepts such as AGC, noise figure, power amplifiers, phase noise, PLL, oscillators/mixers

Understanding of RF and Optical link budgets and noise analysis, intermodulation analysis, and trade-offs of frequency conversion topologies

Familiarity with test equipment such as spectrum analyzers and signal generators

Excellent communication and documentation skills, and ability to collaborate with other engineering disciplines

ADDITIONAL REQUIREMENTS:

Extended hours and weekend work may be required to support critical project and mission milestones
