Principal RF Engineer

Menlo Park, CA

Why LeoLabs?

At LeoLabs, we’re building the living map of activity in space. Through our proprietary global radar network and AI-enabled analytics platform, we collect millions of measurements daily on more than 25,000 objects in low Earth orbit (LEO). Our radar-powered intelligence protects billions in assets, monitors adversarial behavior, and ensures safe operations for commercial and government missions.

We’re not just building technology, we are redefining global security, safety, and transparency in space. As orbital activity accelerates and threats grow more complex, LeoLabs is a trusted partner for Space Domain Awareness, Space Traffic Management, and Satellite Operations for top-tier space operators and allied defense organizations.

If you're looking to work on mission-critical challenges at the forefront of aerospace, national security, and AI, your impact starts here.

As a Principal RF Engineer, you will lead the development of the RF electronics that define the performance of our next-generation radar systems. You will own the most challenging RF design problems across multiple programs, from architecture and requirements through design, validation, and production. This is a hands-on technical leadership role for an experienced engineer who enjoys solving difficult problems, mentoring other engineers, and delivering robust hardware that performs in demanding environments. 

You will work closely with electrical, mechanical, embedded software, manufacturing, and systems engineers to develop high-performance radar hardware from concept through deployment.

  • Work closely with electrical, mechanical, embedded software, and manufacturing engineers to integrate RF hardware into complete radar systems 
  • Conduct technical design reviews and provide mentorship to other RF engineers 
  • Evaluate technical tradeoffs and help define the RF architecture for future radar platforms 
  • Support manufacturing, field deployments, and root-cause investigations as products transition into production 

 Qualifications 

  • Bachelor's degree in Electrical Engineering or a related discipline 
  • 12+ years of experience designing RF and microwave electronics 
  • Deep understanding of RF system design, microwave circuit theory, and radar fundamentals 
  • Demonstrated experience designing complex RF PCBAs from concept through production 
  • Proficiency with Altium Designer or equivalent PCB design software 
  • Experience with RF simulation tools such as ADS and CST 
  • Strong laboratory skills using VNAs, spectrum analyzers, signal generators, oscilloscopes, power meters, and related RF instrumentation 
  • Experience developing engineering tools and automation using Python 
  • Must be eligible to obtain and maintain a U.S. personnel security clearance 

 Preferred Qualifications 

  • Master's degree in Electrical Engineering with an emphasis in RF or microwave engineering 
  • Experience designing radar, aerospace, communications, or defense electronics 
  • Experience with phased arrays, antenna design, or beamforming systems 
  • Experience with RF calibration, metrology, and EMI/EMC mitigation 
  • Familiarity with PLM systems such as Arena 
  • Experience leading technical teams and mentoring engineers 

 

Within 1 month, you’ll: 

Complete onboarding and become familiar with LeoLabs' radar architecture, development process, and RF design environment 

Build an understanding of current hardware programs and future product roadmap 

Begin contributing to ongoing RF design efforts and technical discussions 

 Within 3 months, you’ll: 

  • Take ownership of a major RF subsystem under active development 
  • Lead RF design reviews and guide key architectural decisions 
  • Drive laboratory validation and performance optimization of prototype hardware 

 Within 6 months, you’ll: 

  • Own the RF development of a next-generation radar subsystem from design through prototype validation 
  • Establish yourself as the technical authority for complex RF design challenges 
  • Mentor engineers across the RF & Electrical Engineering Team 

 Within 12 months, you’ll: 

  • Deliver multiple RF designs into production 
  • Shape the RF architecture for future radar platforms 
  • Be recognized as a technical leader whose decisions influence hardware development across the organization 

Compensation 

 Salary offers are based on a combination of factors, including, but not limited to, experience, skills, and location. The base salary range for this position $260,000 + bonus + stock options + benefits  

 All qualified applicants will receive consideration for employment without regard to race, colour, religion, sex, sexual orientation, gender identity, national origin, disability, or status as a protected veteran.  

 ITAR Requirements 

To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be eligible to obtain the required authorizations from the U.S. Department of State. More information regarding ITAR can be found at DDTC’s website

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
