The position scope may also expand to include performing other reliability tasks such as MIL-HDBK-217 predictions, Failure Modes Effects and Criticality Analysis, and Failure Analysis. You will work on teams developing and producing electro-optical, communication, avionics and Electronic Counter Measures for ground, space, airborne and shipboard platforms. BAE Systems Reliability Sciences Engineers are involved with every stage of the equipment lifecycle from concept through development, Integration & Test, production and field support. The selected candidate will have significant interaction across the company including program office, all engineering disciplines and production functions and this will provide for a fast-paced, educational, and fulfilling experience. Your efforts will have a positive impact on front line warfighter s effectiveness and daily quality of life. In this Built In Test ( BIT ) / Reliability Engineer opportunity you will make impacts on the following ways; * Work with a cross-functional team to develop BIT and test automation strategies and methodologies. * Apply your engineering skills and education to investigate, analyze, and evaluate system designs for proper testability. * Ensure the BIT design is adequate to meet customer requirements for fault detection and fault isolation. * Develop Model Based Systems Engineering (MBSE) artifacts including activity diagrams, sequence diagrams, etc. that represent the BIT design. * Influence product development by supporting the design team to establish BIT functions, test interface requirements and diagnostic features. * Supports BIT integration activities by testing or overseeing the testing of BIT features, investigating results, and implementing corrective actions to the BIT design. * Participates in designing algorithms that predict the remaining useful life of the system (prognostics) * Plans and conducts formal BIT Demonstration activities by defining the representative fault list from the testability study, defining the fault insertion methods, performing dry-runs to test the fault insertion methods and modifying BIT software and diagnostic rules based on results of testing. * Presents BIT design and analysis at internal and customer design reviews. * Provide BIT technical support to SW Engineering during SW implementation, Production during ATP, and Field Service Engineers during platform integration. * Perform root cause investigations and implementing corrective actions. Initiates, justifies, and implements BIT-related enhancements needed for improved demonstrated reliability and fault detection, increased production capacity, improved test yields, reduced cycle time, and optimized depot diagnostics. * May perform Design-for Reliability and Maintainability including reliability and maintainability modeling and analysis and assessments requiring the full use and wide application of engineering theories, concepts and precedents. * May perform failure trend analysis, failure investigation and root cause analysis. Chair the Failure Review Board activities. ## Related Videos - [ Secure Code Superstars: Empowering Developers and Surpassing Security Challenges Together](https://www.wearedevelopers.com/videos/422-secure-code-superstars-empowering-developers-and-surpassing-security-challenges-together) - [Debugging Humans: How MBTI Helps Engineering Teams Communicate Better](https://www.wearedevelopers.com/videos/100335-debugging-humans-how-mbti-helps-engineering-teams-communicate-better) - [Old tools, new tricks](https://www.wearedevelopers.com/videos/1916-old-tools-new-tricks) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers)
