About the Job

Requirements

  • A bachelor's degree with at least 6 years of relevant experience, a graduate degree with at least 4 years of relevant experience, or at least 10 years of relevant experience in lieu of a degree.
  • Ability to obtain a U.S. Secret security clearance.
  • Ability to productively use desktop software applications such as Microsoft Office tools, including Outlook, Word, Excel, PowerPoint, and Visio, and related software tools.
  • Ability to work effectively and efficiently in a virtual environment using tools such as Microsoft Teams and Atlassian Jira.
  • Proficiency in advanced Excel methods, including data structures, pivot tables, manipulation, transformation, and visualization.
  • Experience in data mining using business tools, SQL, Power BI, Tableau, Alteryx, or similar data visualization tools.
  • Knowledge and experience in advanced optical systems, electro-optical/infrared sensors, or intelligence, surveillance, and reconnaissance applications.
  • Ability to obtain a flight physical.
  • Understanding and use of reliability software tools such as ReliaSoft, Relex (PTC Windchill), or Reylence.
  • Statistical analysis experience using software tools such as MiniTab, JMP, R, MATLAB, or similar.
  • Technical understanding of electronic components and computer hardware concepts.
  • Technical understanding of troubleshooting complex failure modes involving interactions between software and hardware.
  • Ability to interpret and work in a Model-Based Systems Engineering environment to understand system design and contribute to system modeling in Cameo.

Responsibilities

  • Establish and execute the reliability, availability, and maintainability program, procedures, and databases on an airborne system.
  • Understand failure modes and mechanisms at the physical level, including mechanical, electrical, thermal, and optical, and at the software level, including Built-in Test and interfaces.
  • Review fault isolation and troubleshooting procedures for thoroughness and accuracy.
  • Support or lead Failure Mode and Effects Analysis and Failure Modes, Effects, and Criticality Analysis meetings to ensure real-world failures are captured and mitigated.
  • Calculate observed reliability and mean time between failures and relate the results to other reliability predictions and models, such as reliability block diagrams and fault tree analysis.
  • Lead maintainability analysis throughout aircraft and mission-systems design and development, including mean time to repair and level of repair analysis.
  • Calculate Built-in Test fault detection rate, fault isolation rate, and false alarm rate to support testability analysis.
  • Collaborate with the Software Development team on design for test using Built-in Test and Built-in Test Equipment.
  • Promote Reliability-Centered Maintenance, implement predictive maintenance processes, and recommend logistical and engineering opportunities to improve long-term system sustainability and mission readiness.
  • Contribute to oversight of scheduled and corrective maintenance procedures, recommended spare-parts lists, and tools and test-equipment lists through failure reporting, analysis, and corrective action system trends.
  • Participate in safety analyses, including human-machine interface and other human-factors design principles as they relate to mission operation and success.
  • Apply Integrated Product Support and Integrated Logistics Support principles to provisioning practices and recommendations for a fielded aircraft and mission system to promote operational availability.
  • Collaborate with the Program Team to prevent or mitigate component obsolescence through diminishing manufacturing sources and material shortages work, including supporting parts and component selection for new product design with design engineers.
  • Collaborate with Risk Management to issue or support risks based on predicted and observed reliability data and trends.
  • Create professional, data-driven presentations that brief technical decisions or recommendations to internal stakeholders and external vendors or customers.
  • Set high ethical standards for self and others.
  • Perform other duties as assigned.
  • Travel 10% of the time.

Desired Qualifications

  • A degree in Electrical Engineering, Mechanical Engineering, Industrial Engineering, or Computer Science; related experience is also preferred.
