Software Test & Automation Engineer II

Rockville, MD

 

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.

Who We’re Looking For

We are seeking a skilled and motivated Software Test & Automation Engineer II to develop and maintain automated testing solutions that ensure the reliability, functionality, and performance of our next-generation spacecraft flight software. In this role, you will contribute to software integration, verification, and regression testing by developing automated test frameworks, requirements-based test cases, and test scripts that validate mission-critical spacecraft functions.

You will work closely with flight software, systems engineering, and integration and test teams to support software testing across software-in-the-loop (SIL), hardware-in-the-loop (HIL), and flight-representative environments. This position is ideal for an engineer with strong programming and test automation skills who thrives in a fast-paced environment, enjoys solving complex technical challenges, and is passionate about building reliable software for next-generation space missions.

Where You’ll Make an Impact

  • Develop and maintain automated integration, verification, and regression testing capabilities for spacecraft flight software.
  • Design, implement, and execute requirements-based test cases and automated test scripts to validate flight software functionality and performance.
  • Develop and enhance automated test frameworks using Python, C/C++, or equivalent programming languages.
  • Verify spacecraft command and telemetry processing, mode management, fault management, and other critical flight software functions.
  • Support software testing in software-in-the-loop (SIL), hardware-in-the-loop (HIL), and flight-representative environments.
  • Collaborate with flight software developers, systems engineers, and integration and test teams to identify defects, troubleshoot issues, and support root-cause analysis.
  • Develop and maintain automated regression test suites to ensure software changes do not impact existing functionality.
  • Integrate automated testing into CI/CD pipelines to improve software quality, testing efficiency, and development workflows.
  • Analyze test results, document defects, and generate verification reports to support software readiness and requirements compliance.
  • Support the development and maintenance of software test environments, simulation tools, and test infrastructure.
  • Participate in technical reviews and contribute to improvements in software verification processes, automation tools, and configuration management practices.

What It Takes

  • Bachelor’s degree in Computer Science, Software Engineering, Computer Engineering, Electrical Engineering, Aerospace Engineering, or a related technical field.
  • 2+ years of experience in software development, software testing, test automation, or a related engineering discipline.
  • Strong programming skills in Python, C/C++, or equivalent languages.
  • Experience developing automated test scripts, test frameworks, or software verification tools.
  • Experience testing embedded systems, real-time software, or complex software applications.
  • Understanding of software integration, verification, validation, and regression testing methodologies.
  • Familiarity with automated testing, CI/CD processes, and software configuration management practices.
  • Experience with software debugging, troubleshooting, and defect tracking.
  • Strong analytical, problem-solving, and communication skills with the ability to work effectively in a collaborative engineering environment.

Nice-to-Have Experience

  • Experience with spacecraft flight software, satellite systems, avionics, or other mission-critical embedded software.
  • Familiarity with spacecraft flight software architectures, command and telemetry processing, mode management, and fault detection and recovery.
  • Hands-on experience with software-in-the-loop (SIL) and hardware-in-the-loop (HIL) testing environments.
  • Experience developing automated test frameworks using Python, pytest, or similar testing tools.
  • Experience working with real-time operating systems (RTOS), embedded Linux, or similar environments.
  • Familiarity with spacecraft simulation tools, ground support equipment, or flight-representative test environments.
  • Experience with CI/CD tools such as Jenkins, GitLab CI/CD, or GitHub Actions.
  • Experience with Git, JIRA, or similar software development and configuration management tools.
  • Understanding of requirements traceability, test coverage analysis, and software verification and validation (V&V) processes.
  • Experience supporting spacecraft integration and testing, software qualification, or mission readiness activities.

What You’ll Get

  • Ownership – Develop and maintain automated testing solutions that directly contribute to the reliability and performance of mission-critical spacecraft flight software.
  • Innovation – Support transformative aerospace and defense programs enabling next-generation space mobility and operations.
  • Impact – Help ensure spacecraft flight software meets critical performance, reliability, and mission readiness requirements through automated verification and testing.
  • Growth – Join a collaborative engineering team working across flight software, systems engineering, and spacecraft integration and testing in a fast-paced, innovative environment.
  • Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing.

Location: Rockville, MD 

Base Salary: $100,000-140,000
