## About the Role

* 7+ years of professional experience in software test, verification, validation, test automation, embedded software, or systems integration engineering.
\n

 * Demonstrated experience verifying embedded, real-time, safety-critical, or mission-critical software in aviation, aerospace, defense, UAS/drone, eVTOL, avionics, automotive safety, medical devices, or a similarly regulated environment.
\n

 * Hands-on experience developing automated test software, test harnesses, simulation tools, regression suites, or hardware-in-the-loop test solutions.
\n

 * Strong programming ability in Python and/or C/C++; experience with scripting and test-tool development is essential.
\n

 * Experience performing unit, integration, system, regression, and requirements-based testing for embedded or real-time systems.
\n

 * Working knowledge of the software development lifecycle, including requirements, design, implementation, verification, configuration management, issue tracking, and release readiness.
\n

 * Ability to interpret software requirements, interface-control documents, electrical schematics, hardware documentation, and system-level architecture.
\n

 * Familiarity with embedded hardware, microcontrollers/processors, RTOS or bare-metal environments, sensors, actuators, and device communication interfaces.
\n

 * Experience troubleshooting software and test failures using logs, debuggers, telemetry, lab equipment, and structured root-cause analysis.
\n

 * Strong documentation, analytical, communication, and cross-functional collaboration skills.
\n, * Experience working on software developed to DAL A, DAL B, DAL C, or DAL D objectives.
\n

 * Familiarity with DO-178C supplements and related guidance, including DO-330 tool qualification, DO-331 model-based development and verification, DO-332 object-oriented technology, or DO-333 formal methods.
\n

 * Experience creating or reviewing Software Verification Plans, verification procedures, test cases, test reports, Software Accomplishment Summaries, problem reports, or certification-review artifacts.
\n

 * Experience with structural coverage tools and analysis, including statement coverage, decision coverage, MC/DC, and data/control coupling analysis.
\n

 * Experience with verification and test toolchains such as VectorCAST, LDRA, Rapita, Cantata, Tessy, IBM Rational Test RealTime, Polyspace, or comparable tooling.
\n

 * Experience developing or supporting HIL, SIL, PIL, integration-lab, simulation, digital-twin, or automated test-bench environments.
\n

 * Familiarity with requirements and lifecycle-management tools such as DOORS, Polarion, Jama, Codebeamer, Jira, Git, Jenkins, GitLab CI, or comparable platforms.
\n

 * Experience with MATLAB/Simulink, model-based testing, test-vector generation, or simulation-based verification.
\n

 * Familiarity with aircraft and avionics interfaces, including ARINC 429, ARINC 664/AFDX, CAN Aerospace, MIL-STD-1553, Ethernet, or serial communication protocols.
\n

 * Experience supporting FAA, EASA, military-airworthiness, UAS, or eVTOL certification programs.
\n

 * Knowledge of DO-254, ARP4754A, ARP4761, systems safety, configuration management, or quality-assurance processes in an aerospace environment.
