Electrical Engineer II – Spacecraft Programs (FlatSat)

Rockville, MD

Who We’re Looking For

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly. We are seeking a motivated and technically capable Electrical Engineer to support the design, development, integration, and testing of spacecraft electrical systems and defense-related space technologies. In this role, you will contribute to spacecraft avionics, communications, power systems, embedded electronics, and hardware integration activities while collaborating closely with multidisciplinary engineering teams. You will work hands-on with cutting-edge aerospace hardware in a fast-paced environment supporting national security and spaceflight missions.

We are seeking an Electrical Engineer II to support the deployment, integration, and long-term maintenance of spacecraft FlatSat systems utilizing engineering models of flight hardware, software and hardware emulators, and associated EGSE. This role is intended for an engineer who thrives at the intersection of hardware integration, debugging, systems validation, and multidisciplinary coordination.

You will work closely with systems, avionics, power, RF communications, flight software, ground software, GNC, and payload teams to integrate spacecraft subsystems into cohesive vehicle-level test environments supporting development, integration, launch preparation, and on-orbit operations.

Where You’ll Make an Impact

Deploy, integrate, and maintain spacecraft FlatSat environments utilizing engineering models, hardware emulators, software simulators, and associated EGSE
Support development of cohesive spacecraft-level integration environments enabling subsystem validation, vehicle checkout, and mission readiness activities
Serve as an early hardware owner responsible for integrating discrete spacecraft subsystems into a unified flight-like system
Support ongoing maintenance and operational readiness of FlatSat platforms throughout spacecraft development and post-deployment mission operations
Collaborate across avionics, RF communications, power, flight software, ground software, GNC, payload, and systems engineering teams to support end-to-end spacecraft integration
Perform hardware bring-up, debugging, troubleshooting, and anomaly resolution activities across integrated spacecraft systems
Develop and maintain integration procedures, test configurations, interface documentation, and operational workflows
Support design and integration of EGSE hardware, harnessing, and supporting infrastructure required for FlatSat operation
Assist with system-level integration testing, spacecraft checkout, regression testing, and mission support activities
Operate within fast-paced development environments requiring strong ownership, adaptability, and cross-functional coordination

What It Takes

B.S. in Electrical Engineering or related technical discipline
3+ years of experience developing electronics hardware for aerospace applications
Experience with spacecraft and embedded communication interfaces including RS-422/485, CAN, LVDS, SpaceWire, and Gigabit Ethernet
Familiarity with standard electronics laboratory equipment including DMMs, oscilloscopes, power supplies, and spectrum analyzers
Strong troubleshooting, debugging, and root-cause analysis capability across integrated hardware systems
Ability to coordinate effectively across multiple engineering disciplines and spacecraft subsystems
Strong organizational and communication skills within multidisciplinary technical teams
Comfortable operating in fast-paced, iterative spacecraft development environments
Hands-on mindset with strong system-level awareness and integration intuition

Nice-to-Have Experience

M.S. in Electrical Engineering or related discipline
Experience designing and building custom hardware emulators and EGSE systems
Experience designing and fabricating EGSE harnessing and electrical interfaces
Python scripting experience supporting automation, validation, or hardware control workflows
Experience with EGSE mechanical enclosure design and integration
Experience supporting spacecraft assembly, integration, and test (AI&T) activities
Familiarity with spacecraft avionics architectures and hardware-in-the-loop (HIL) test environments
Experience supporting mission operations or post-deployment spacecraft support activities

What You’ll Get

Ownership – Become a primary hardware owner responsible for spacecraft-level FlatSat integration and operational readiness
Innovation – Build and maintain living spacecraft testbeds supporting next-generation high-mobility missions
Impact – Enable subsystem integration, spacecraft validation, and mission success from development through on-orbit operations
Growth – Work across nearly every spacecraft subsystem while developing deep integration and systems-level expertise
Compensation – Base Salary Range: $100,000 - $125,000 - Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing

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.

Apply now. Join us in building the integrated spacecraft systems that enable reliable mission execution from development through on-orbit operations.

Voluntary Self-Identification

For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file.

As set forth in Quantum Space’s Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law.

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.
