Join us in championing and protecting explorers and heroes! As a Test Engineer III, you will lead the development and execution of comprehensive test plans for advanced aerospace and defense systems. This role requires in-depth expertise in testing methodologies and the ability to manage multiple test projects simultaneously, ensuring product compliance and performance. Our testing approach evolves with the design maturity, extending from initial stages through to post-production follow-ups on subsequent articles. The role involves extensive system testing, aimed at assessing a broad spectrum of mission equipment such as communication, computing, navigation, and surveillance systems, to ensure they meet design and functionality standards. Please note, this role does not require any knowledge or skills related to software or automation testing. The ISR (Intelligence, Surveillance & Reconnaissance), Aviation, and Security (IAS) business area is a leader in ISR and aviation, it is a leading prime manned and unmanned aircraft systems integrator for innovative, high-performance ISR and aviation systems. Its end-to-end Command, Control, Computers, Communications and Intelligence, Surveillance & Reconnaissance (C4ISR) capabilities encompass design, integration, test, certification, ground/flight training and complete logistics support. IAS tailors solutions to customer cost, performance, and schedule requirements and designs to consistently exceed expectations - with an unrivaled record of on time and on (or under) budget deliveries. Responsibilities: * Lead the development and execution of comprehensive test plans and procedures. * Oversee system-level, sub-system, and component-level testing, including functional, performance, and environmental test. * Perform detailed analysis of test data, identify root causes of issues, and provide actionable recommendations in a comprehensive test report. * Identify, document, troubleshoot, and facilitate resolution of issues and anomalies. * Coordinate with cross-functional teams to define test requirements and strategies. * Ensure test processes and equipment meet industry standards and regulatory requirements. * Generate content and lead internal/external meetings and briefs. ## Related Videos - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [10M Data Records Lost, Underwater Computing, and Psychedelic Fish - Matthias Geniar](https://www.wearedevelopers.com/videos/1908-10m-data-records-lost-underwater-computing-and-psychedelic-fish-matthias-geniar) - [SMART Test Automation - the experience of legacy transformation](https://www.wearedevelopers.com/videos/100215-smart-test-automation-the-experience-of-legacy-transformation) - [Stop Guessing, Start Measuring: Evaluating RAG Systems with Synthetic Test Data](https://www.wearedevelopers.com/videos/1982-stop-guessing-start-measuring-evaluating-rag-systems-with-synthetic-test-data) - [Develop on Windows, Deploy on Red Hat Enterprise Linux](https://www.wearedevelopers.com/videos/1600-develop-on-windows-deploy-on-red-hat-enterprise-linux) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges)
