Simulation, Test, Verification and Validation Engineer, Airborne Systems

Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries.

The Simulation, Test, Verification and Validation Engineer is responsible for designing, implementing, and operating the integrated test ecosystem that spans Software-in-the-Loop (SITL), Hardware-in-the-Loop (HITL), and large-scale simulation environments including the Joint Simulation Environment (JSE). This role requires strong software engineering skills to develop test harnesses, simulation adapters, OMS/UCI validation tools, automated regression frameworks, scenario generators, and data-analysis pipelines. The engineer ensures that all mission systems, autonomy behaviors, operator workflows, and airborne software integrate correctly, behave deterministically, and comply with the aircraft’s Interface Control Document (ICD). The position supports the full lifecycle of Verification and Validation (V&V), from requirements decomposition through simulation, ground test, and flight test evidence collection, culminating in complete, review-ready deliverables for internal teams and external partners.

• Design and implement integrated simulation environments: construct and maintain SITL, HITL, and Joint Simulation Environment (JSE) configurations that accurately represent mission system software, autonomy behaviors, vehicle dynamics, control laws, communication paths, and operator interfaces; implement simulation adapters, message brokers, and runtime environments required for deterministic integration.
• Develop OMS and UCI-based test frameworks: write software tools, message validators, schema checkers, and automated conformance suites to verify compliance with Open Mission Systems (OMS) and Universal Command and Control Interface (UCI) services; embed automated quality checks for every mission system and autonomy service.
• Create automated test harnesses and regression suites: develop code-driven test automation for APIs, state machines, data schemas, autonomy behaviors, and subsystem interactions; ensure repeatable, traceable, and auditable testing for every integration event.
• Build scenario generators and test cases: author simulation scenarios that represent flight conditions, environmental constraints, subsystem failures, degraded modes, and edge cases that validate system behavior; map scenarios to subsystem requirements and V&V objectives.
• Integrate airborne and ground software into testbeds: embed autonomy software, mission-system modules, ground-segment components, telemetry handlers, and operator interface code into simulation frameworks; ensure execution fidelity and consistent interpretation of ICD-defined messages.
• Develop evidence pipelines for V&V: implement data logging, metadata tagging, event annotation, timing correlation, and trace extraction logic across SITL, HITL, simulation, and flight test environments; ensure clear provenance and traceability of evidence to requirements.
• Debug cross-system interactions: analyze logs, telemetry traces, simulation timelines, message exchanges, and behavior state transitions to identify root causes of integration issues; implement code fixes, configuration corrections, or scenario modifications to resolve them.
• Support ground and flight test execution: prepare test configurations, instrumentation code, playback utilities, and pre-flight validation artifacts; ensure systems are correctly configured for controlled execution and data collection.
• Ensure ICD conformance across all test contexts: validate software and subsystem behaviors against ICD-defined interfaces, message schemas, and service models; maintain conformance matrices, schema diff tools, and automated checks that detect interface regressions.
• Collaborate across engineering teams: work closely with autonomy, mission systems, ground segment, avionics, and flight-test teams to ensure simulation and test systems represent real-world behavior and provide meaningful evidence for evaluation.
• Generate end-product deliverables for internal and external customers: produce high-quality, traceable, and review-ready engineering artifacts including documentation, reports, data packages, analysis outputs, software integrations, and configuration updates that meet program requirements, support design reviews, and satisfy customer or partner expectations.
• Communicate test readiness and integration status: provide clear updates on simulation fidelity, test completeness, regression stability, known issues, and readiness for ground or flight test to program leadership.

• Bachelor’s or Master’s degree in Computer Engineering, Software Engineering, Aerospace Engineering, Electrical Engineering, or a related technical discipline with significant software experience.
• 8+ years of experience developing or integrating simulation environments, test frameworks, or mission systems software for unmanned aerial systems (UAS), autonomous platforms, aerospace systems, or complex distributed software architectures.
• Strong proficiency in software development using languages such as C++, Python, or similar for simulation integrations, test automation, and tool development.
• Demonstrated expertise with Open Mission Systems (OMS) and Universal Command and Control Interface (UCI) schemas, message catalogs, service definitions, and validation mechanisms.
• Experience developing and operating Software-in-the-Loop (SITL), Hardware-in-the-Loop (HITL), and Joint Simulation Environment (JSE) testbeds.
• Ability to design and implement automated test harnesses, regression suites, scenario generators, and data-analysis pipelines for mission systems or autonomy software.
• Experience building or validating simulation adapters, protocol translators, message brokers, and time-synchronization tools.
• Familiarity with autonomy behaviors, state machines, trajectory planners, and control-system interactions in simulated and real environments.
• Strong debugging and analysis skills including log interpretation, telemetry correlation, and code-level fault isolation.
• Proficiency with software development workflows including Git, continuous integration, automated testing, and code review processes.
• Ability to communicate integration and test results clearly across multidisciplinary teams.
• Active Secret clearance required; Top Secret / Sensitive Compartmented Information (TS/SCI) preferred.
