Reviews designs of other engineering team members to drive quality and reduce defects via simulations. Leads definition of system availability calculations based on analysis of Schematics, Bill of Materials, and predictive reliability databases. Trains other engineers to use FMEDA techniques to determine reliability and availability of modules. Designs and tests validation hardware for 28 mm industrial controls ASICs interconnected on a passive cable assembly. Performs acceptance testing and prototyping. Analyze the power requirements and determine the system availability for Redundant Fault Tolerant passive cable assemblies. Stays current and well informed on hardware engineering methodologies and technologies germane to the company's industry through personal research, training and seminar participation. Leads design modifications and tests to align automation IO products to exceed required UL508 certification levels for temperature and humidity, hi-pot, Equipment Fault tests and audits. Determines system margins and design limits of production circuitry. Performs design modifications and tests to align automation IO products to exceed CE standards specific to EMC. Leads team through production certification activities and maintains a detailed work breakdown and schedule for portions of control hardware projects. Works with the managers and development team to determine the contents of milestones and incorporate this data into the schedule. Optimizes component selection and stays current with latest methodologies and technologies for ISA Standard 71.04-1985 environmental design. Optimizes component selection and design techniques to mitigate the impact of component degradation to preserve system availability and reliability. Designs SIL2 and SIL3 circuits for analog and/or digital safety applications based on collaborating with safety architecture and marketing teams. Ensures development team's participation in the review of requirements and design specifications that may impact the team's area of responsibility. Leads and provides input in product architecture, analysis and test plans activities. Develops power supply circuits for Fault Tolerant Redundant Applications requiring annunciation of fault behaviors. Assumes technical leadership of small team and/or mentoring of new engineers through the process of product development of Redundant Fault Tolerant IO systems.
