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 The salary range for this role is an estimate based on a wide range of compensation factors. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations. Highly competitive equity grants are included in the majority of full time offers; and are considered part of Quantum Space's total compensation package.
