Job details

Experience: 8+ years of experience RF engineering
Posting language: English
Posted: Nov 13, 2026

Original 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.

PRINCIPAL RF ENGINEER (STARSHIELD)

Starshield leverages SpaceX’s Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads. As an RF engineer on the Starshield team, you will be working on advanced development programs in support of US National Security. You will work with a team of fellow RF engineers, DSP engineers, software engineers, hardware engineers and end users to design and build RF capabilities for proliferated communications and remote sensing in low earth orbit. You will work in a highly collaborative and fast-paced environment, where we are exploring unsolved problems and applying the SpaceX mindset of iterating rapidly to go from design and demo to operational capability at lightning pace.

RESPONSIBILITIES:

Drive program-level decisions on RF system designs
Research novel solutions for unique large-scale satellite RF systems
Work in close collaboration with hardware, FPGA, DSP, and software engineers to design and validate RF systems
Responsible for development and full life cycle support of RF hardware spanning PCBA board testing and defect detection, full functional testing of an assembled unit, and resolving on-orbit vehicle anomalies
Create electromagnetic simulation models of hardware (antennas, filters, PCB layout) to design and evaluate performance
Modify electrical schematics and mechanical drawings for flight applications as they relate to reliability and manufacturability

BASIC QUALIFICATIONS:

Bachelor’s degree in computer engineering, or electrical engineering
8+ years of experience RF engineering
Experience with modeling/analysis tools/software such as HFSS, CST, ADS, MATLAB, C/C++, and/or Python
Experience with RF test equipment such as VNA, spectrum analyzer, etc.
Experience creating and maintaining link budgets and analysis related to communications or remote sensing systems

PREFERRED SKILLS AND EXPERIENCE:

Master’s degree in electrical engineering with emphasis in microwave/RF engineering
Experience modeling RF and channel impairments such as multipath, phase noise, group delay, fading and nonlinear distortion
Experience designing RF systems including radio astronomy, SIGINT, ELINT, radar, or wireless communications
Experience with basic principles of antenna theory
Experience with software-defined radios and frameworks, such as GNU Radio
Ability to obtain and maintain a Top Secret SCI clearance

ADDITIONAL REQUIREMENTS:

An active clearance may provide the opportunity for you to work on sensitive SpaceX missions; if so, you will be subject to pre-employment drug and random drug and alcohol testing
Must be willing to work extended hours and weekends as needed

COMPENSATION AND BENEFITS:

Pay Range:

Level 3: $210,000.00 - $340,000.00

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.

Those with an active clearance will receive a 10% differential, up to an additional $20,000 annually, once officially briefed into a classified program.

ITAR REQUIREMENTS:

To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.
