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.

SR. DSP SYSTEMS ENGINEER (SILICON ENGINEERING)

At SpaceX we're leveraging our experience in building rockets and spacecraft to deploy Starlink, the world's most advanced broadband internet system. Starlink is the world's largest satellite constellation and is providing fast, reliable internet to millions of users worldwide. We design, build, test, and operate all parts of the system - thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We've only begun to scratch the surface of Starlink's potential global impact and are looking for best-in-class engineers to help maximize Starlink's utility for communities and businesses around the globe.

We are seeking a motivated, proactive, and intellectually curious engineer who will work alongside world-class cross-disciplinary teams (systems, firmware, architecture, design, validation, product engineering, ASIC implementation). In this role, you will be developing cutting-edge next-generation ASICs for deployment in space and ground infrastructures around the globe. These chips are enabling connectivity in places it has previously not been available, affordable or reliable. Your efforts will help deliver cutting-edge solutions that will expand the performance and capabilities of the Starlink network.

RESPONSIBILITIES

• Drive program-level decisions on sensor firmware, software, and AI-driven architecture for large-scale RF sensing and satellite broadband systems
• Research and develop novel solutions incorporating advanced digital beamforming, massive MIMO, and direct-to-device technology for on-orbit and ground-based applications
• Design, model, and test algorithms for system-level and link-level performance, including floating-point/fixed-point simulations of modem, beamforming, and sensor data processing
• Work in close collaboration with ASIC/FPGA, RF/antenna, and software engineers to design, validate, and bring up silicon-based RF sensing and communication systems
• Generate spacecraft/consumer equipment specifications, requirements, test procedures, and bit-/cycle-accurate vectors; support silicon bring-up, on-orbit demonstrations, and system validation
• Analyze overall system performance (including link budgets, impairments, and multi-access schemes) and implement system test plans under dynamic program needs

BASIC QUALIFICATIONS

• Bachelor's degree in computer science, electrical/computer engineering, physics, math, or other STEM discipline
• 5+ years of experience in system-level modeling, digital signal processing, or RF/wireless system design

PREFERRED SKILLS AND EXPERIENCE

• Master's degree in electrical engineering with emphasis in communication systems, digital signal processing, or related fields
• Experience with AI-driven architecture, advanced digital beamforming, massive MIMO, and direct-to-device technologies
• Professional experience working on RF sensors or wireless modems
• Experience modeling RF and channel impairments (multipath, phase noise, group delay, fading, nonlinear distortion) and building system-level simulators
• Expertise in multiple access schemes (TDMA, CDMA, OFDMA), high-data-rate modem design/verification, and wireless standards (LTE, WiFi, etc.)
• Proficiency in MATLAB, C/C++, and/or Python; experience with software-defined radios (e.g., GNU Radio)
• Strong understanding of link budgets, modem algorithms, hardware architectures, ASIC/FPGA development flows, and lab equipment
• Experience with Git, Atlassian tools (JIRA, Confluence, Bitbucket, Bamboo), and cross-functional collaboration

ADDITIONAL REQUIREMENTS

• Ability to work extended hours and weekends as needed to support critical project and mission milestones

COMPENSATION AND BENEFITS

• Pay Range:
• Level 3: $165,000.00 - $265,000.00

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 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.
