Recommends design or test methods and statistical process control procedures for achieving required levels of product reliability. Compiles and analyzes performance reports and process control statistics; investigates and analyzes relevant variables potentially affecting product and processes. Ensures that corrective measures meet acceptable reliability standards. Analyzes preliminary plans and develops reliability engineering programs to achieve company, customer and governmental agency reliability objectives. May develop mathematical models to identify units, batches or processes posing excessive failure risks. As necessary, proposes changes in design or formulation to improve system and/or process reliability. May determine units and/or batches requiring environmental testing, and specifies minimum number of samples to obtain statistically valid data., You will be the Senior Reliability Engineer for the PAC-3 Launcher Sustainment Reliability Team. Our team safeguards product performance by identifying hidden failure risks, providing actionable metrics/corrective actions to program stakeholders, and delivering data driven mitigation strategies that keep our systems on track from concept through field service. What You Will Be Doing As the Senior Reliability Engineer you will be responsible for leading the FRACAS process and trending development, as well as data analysis to provide program stakeholders with actionable metrics to improve overall launcher performance. You will work hand in hand with design/quality/chief engineers, and program managers to surface risks early, quantify them accurately, and drive corrective actions. Your responsibilities will include: * Identify failure modes, root causes, and their effects on overall system performance. * Assign criticality rankings, document mitigation strategies, and track them through each development phase. * Update, analyze and trend all FRACAS data in Windchill. * Automate available test data analysis tools and provide metrics to program stakeholders in a Corrective Action Board (CAB). * Analyze test data, generate reliability growth curves, and report findings to cross functional stakeholders. * Recommend design or material changes to improve reliability and reduce lifecycle cost. * Mentor junior reliability engineers and contribute to continuous improvement initiatives within the reliability organization. ## Related Videos - [Leading with Reliability: Applying SRE Principles to Build Stronger Engineering Organizations](https://www.wearedevelopers.com/videos/100185-leading-with-reliability-applying-sre-principles-to-build-stronger-engineering-organizations) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [SRE Methods In an Agency Environment](https://www.wearedevelopers.com/videos/348-sre-methods-in-an-agency-environment) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) ## Related Articles - [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) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
