Job Title: Software Test Engineer (Level 1 and Level 4)
Job Description
This role supports the verification of unmanned aircraft systems (UAS) software in a disciplined aerospace environment. At Level 1, you will help plan, execute, and document software tests under the guidance of senior engineers, focusing on repeatable test execution and accurate evidence of requirements verification. At Level 4, you will lead the planning, development, execution, and continuous improvement of software verification activities, defining strategies, building automated and hardware-in-the-loop capabilities, and ensuring comprehensive, defensible test evidence for complex UAS programs.
Responsibilities
- Develop and execute software test procedures based on approved requirements, designs, and interface documentation.
- Perform functional, integration, regression, and system-level testing in laboratory and hardware-in-the-loop environments.
- Document test configurations, procedures, results, anomalies, and objective evidence in accordance with established processes.
- Reproduce software defects, collect relevant logs and data, and collaborate with developers to support root-cause analysis.
- Maintain test scripts, test data, simulators, and laboratory equipment under configuration control.
- Support requirements reviews and traceability activities to help ensure complete verification coverage.
- Participate in test readiness reviews and communicate test status, risks, and blockers to the project team.
- Follow safety, cybersecurity, configuration-management, and quality procedures applicable to aerospace software testing.
- Define software verification strategies, plans, procedures, environments, and acceptance criteria for complex UAS programs.
- Lead functional, integration, regression, performance, robustness, and system-level testing across software and hardware boundaries.
- Design and maintain automated test frameworks, simulators, test harnesses, and hardware-in-the-loop capabilities.
- Review system and software requirements and architectures for testability, ambiguity, completeness, and verification coverage.
- Analyze complex failures, lead defect triage and root-cause investigations, and verify corrective actions.
- Establish bidirectional traceability among requirements, test cases, results, anomalies, and configuration baselines.
- Lead test readiness and results reviews while clearly communicating technical risk and verification status.
- Mentor junior test engineers and foster a culture of disciplined, high-quality testing practices.
- Continuously improve test processes, metrics, tools, and laboratory practices while supporting program safety and compliance objectives.
Essential Skills

- 0–2 years of software test, software development, systems integration, or related engineering experience for Level 1.
- 7+ years of software test, verification, integration, or related engineering experience for Level 4.
- Foundational knowledge of software test methods, defect tracking, and requirements-based verification for Level 1.
- Demonstrated experience leading requirements-based verification for embedded or mission-critical software for Level 4.
- Experience with at least one programming or scripting language such as Python, C, C++, or Java.
- Strong proficiency in test automation and scripting using languages such as Python, C, or C++ for Level 4.
- Experience with hardware-in-the-loop testing, real-time systems, interfaces, laboratory equipment, and data analysis for Level 4.
- Basic familiarity with version control and issue-tracking tools for Level 1.
- Working knowledge of configuration management, requirements traceability, defect management, and CI/CD practices for Level 4.
- Strong analytical, troubleshooting, teamwork, and written communication skills.
- Strong technical leadership, problem-solving, review, and communication skills for Level 4.
- Ability to read technical requirements, follow controlled procedures, and produce clear, accurate test records.
- Must have or be able to obtain a U.S. SECRET security clearance.
- Experience in software test, software development, systems integration, or related engineering fields.
- Knowledge of aerospace and defense software testing practices, including safety and flight-related test activities.
- Familiarity with network protocols, simulation, Linux, and CI/CD tools.
Additional Skills & Qualifications
- Internship, academic, or professional experience testing embedded, real-time, aerospace, defense, or UAS software for Level 1.
- Exposure to automated testing, continuous integration, hardware-in-the-loop systems, or laboratory instrumentation for Level 1.
- Familiarity with DO-178C, MIL-STD-882, requirements traceability, or software configuration management for Level 1.
- Experience working in Linux environments and analyzing logs, network traffic, or serial communications for Level 1.
- Experience in UAS, aerospace, defense, flight controls, avionics, or other safety-critical software domains for Level 4.
- Familiarity with verification objectives, structural coverage, tool qualification, and MIL-STD-882 safety processes or similar commercial standards for Level 4.
- Experience qualifying test environments, developing test infrastructure, or supporting formal customer acceptance events for Level 4.
- Knowledge of cybersecurity testing, network protocols, simulation, model-based testing, or real-time operating systems for Level 4.
- Interest in supporting UAS programs and contributing to advanced unmanned aircraft systems.
- Experience with test, safety, flight, and network protocol analysis in aerospace or defense contexts.
- Experience in safety-related standards such as DO-178C and MIL-STD-882.
- Experience with CI/CD pipelines and modern software delivery practices.
- Ability to work effectively in cross-functional engineering teams and communicate clearly with stakeholders at different technical levels.
