Software Development Engineer in Test

Automated Test Development & Validation

Design, develop, and maintain automated test frameworks supporting Dragonfly's microservices-based software architecture, browser-based tactical user interface, RF signal processing pipelines, and REST/GraphQL APIs.

Develop and maintain comprehensive test plans, test procedures, test cases, and requirements traceability matrices aligned with system-level requirements, customer objectives, and mission use cases.

Collaborate with software, hardware, and systems engineering teams to define acceptance criteria, identify defects early in the development lifecycle, and support quality assurance activities within CI/CD pipelines.

Maintain automated regression test suites to ensure software stability, performance, and repeatability across product releases.

System Integration & Hardware-in-the-Loop Testing

Perform hardware-in-the-loop (HIL) testing across the complete Dragonfly platform, including processing units, direction-finding antennas, software-defined radios, and associated peripherals.

Validate subsystem and end-to-end system integrations, ensuring interoperability between Dragonfly, external partner systems, and command-and-control (C2) platforms.

Verify system functionality, data flow integrity, and operational performance across integrated hardware and software environments.

Support verification activities for new hardware configurations, software releases, and system enhancements prior to operational deployment.

RF Performance & Mission Capability Verification

Execute structured laboratory testing of RF detection, direction finding, geolocation, EMCON monitoring, and spectrum awareness capabilities against documented requirements and performance specifications.

Validate GPU-accelerated digital signal processing functions, including multi-channel direction finding, signal correlation, emitter characterization, and machine learning-based antenna calibration algorithms.

Verify wide-band survey operations, signal classification, direction finding accuracy, and real-time signal processing performance across representative operational scenarios.

Conduct RF performance assessments to ensure mission systems meet accuracy, responsiveness, and operational effectiveness requirements.

Field Testing & Operational Evaluation

Plan and execute outdoor field testing activities involving live RF signal collection and operational system employment.

Evaluate system performance under realistic environmental conditions, validating signal detection, geolocation accuracy, direction finding performance, and spectrum monitoring capabilities.

Document environmental variables, test configurations, and operational conditions to ensure repeatable and defensible test results.

Support customer demonstrations, operational assessments, and field validation events as required.

Test Documentation & Continuous Improvement

Document test results, anomalies, defect reports, regression outcomes, and corrective actions with clear reproduction steps and supporting technical evidence.

Maintain detailed testing records, quality documentation, and verification artifacts supporting system acceptance and product readiness reviews.

Analyze test results and performance trends to identify reliability issues, software defects, integration risks, and opportunities for system improvement.

Contribute to continuous improvement initiatives by refining test methodologies, expanding automation coverage, and improving overall product quality and mission readiness.
