Electrical AI&T Engineer III - Advanced Programs

Hawthorne, CA

Who We’re Looking For 

Quantum Space is developing high-performance spacecraft designed for agility, autonomy, and mission longevity in cislunar space. We are seeking a highly skilled Electrical Engineer – EGSE, AI&T to lead the development and integration of electrical ground support equipment (EGSE) systems and to support spacecraft assembly, integration, and test (AI&T) activities. 

This role is ideal for an experienced electrical engineer who thrives at the intersection of hardware development, systems integration, and test execution. You will be a key contributor to ensuring safe and successful vehicle build-up and mission readiness. 

Where You’ll Make an Impact 

  • Design, procure, assemble, and operate EGSE systems for spacecraft AI&T including power distribution, communications, telemetry/command, RF test, and custom hardware interfaces 
  • Design and build EGSE harnesses for interfacing test equipment and spacecraft systems 
  • Lead spacecraft electrical system integration across avionics, EPS, communications, and propulsion subsystems 
  • Write and execute implementation plans, test procedures, and build documentation 
  • Troubleshoot and resolve anomalies observed during integration and test operations 
  • Support vehicle-level environmental testing (TVAC, vibration, EMI/EMC) 
  • Support program milestones including PDR, CDR, MRR, and TRR 
  • Operate within cleanroom and ESD-controlled environments around flight hardware 
  • Create technical documentation and interface control documents (ICDs) for EGSE and AI&T handoffs across teams 
  • Develop and run automated test scripts and code for hardware validation and regression testing 

What It Takes 

  • B.S. or M.S. in Electrical, Computer, Aerospace Engineering, or a related discipline 
  • 5+ years of experience supporting spacecraft flight hardware and integration environments 
  • Experience architecting and deploying EGSE systems including power, command & telemetry, RF, and custom interfaces 
  • Familiarity with spacecraft integration processes and spacecraft build flows 
  • Ability to lead subsystem and vehicle-level electrical integration and testing 
  • Strong skills in technical writing, procedure authorship, and troubleshooting 
  • Experience developing and executing automated test scripts (e.g., Python) 
  • Proficient with test equipment such as oscilloscopes, multimeters, power supplies 
  • Experience with code verification and validation best practices 
  • Familiarity with ESD-safe handling procedures and cleanroom protocols 
  • Strong cross-functional awareness and systems-level thinking 
  • Comfortable operating in a fast-paced, iterative environment where priorities shift quickly 
  • Work location within the LA area

Nice-to-Have Experience 

  • Strong background in core EE fundamentals (analog/digital circuits, power, grounding, etc.) 
  • Experience with spacecraft data buses and interfaces (RS422/RS485, SpaceWire, Ethernet, SERDES, LVDS, CAN, Discrete IO, Cameralink) 
  • Familiarity with avionics system architecture, electrical power system (EPS) architecture, and spacecraft power modeling 
  • Hands-on experience with ECAD tools like OrCAD or Altium for schematic capture, layout, and parts library management 
  • Experience with circuit simulation tools (e.g., LTSpice, PSpice) 
  • Experience with FPGA-based systems and HDL programming (VHDL, Verilog) 
  • Certification in NASA-STD-8739.4, IPC-620, J-STD-001, IPC-7711/7721 
  • Experience authoring and validating spacecraft electrical system requirements 
  • Project management or test campaign leadership experience 

What You’ll Get 

  • Ownership – Lead the development and operation of EGSE systems across mission phases 
  • Innovation – Build custom tools and processes to accelerate integration and test 
  • Impact – Be a critical enabler for mission readiness and system-level success 
  • Growth – Join a rapidly growing engineering team at the core of hardware execution 
  • Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing 

Location: Hawthorne, CA

Compensation: $125,000 to $180,000 Annual Salary Depending on Experience

Additional Requirements 

To comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

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.
