Sr. Scientist – Multi-Physics Modeling

Sierra Nevada Corporation

This is a Full-time position in Centennial, CO posted July 1, 2020.

The Scientist will play a key role in the design and development of a nano/micron scale energy conversion device. In this role, the engineer will be responsible for defining, documenting, and communicating a design architecture that meets all requirement specifications in regards to performance, cost and schedule


  • Develop,  refine, and use physics-based models to quantify expected technology performance bounds of various energy conversion devices
  • Perform thermal and electron transport analysis at detailed component level and at the systems level
  • Conduct literature research and utilize scientific community networks to aggregate and organize relevant data
  • Assist in efforts to correlate models to experimental data and test results
  • Perform complex engineering/scientific analysis with moderate direction and supervision to support the design and development of the integration of energy conversion devices into products
  • Plan and participate in experimental testing to support design development
  • Assist Project/Program managers in formulating technical approaches to device design that meet system requirements
  • Initiate, understand, plan, and execute technical activities in accordance with, SNC’s policies, procedures, and work instructions and specific Customer requirements to include generation of scientific reporting and planning documents.
  • Originate research papers, design documents, specifications, control documents, verification and validation plans, procedures, reports, presentations or other documentation in support of design, research and development activities
  • Prepare material for, and conduct, periodic progress reviews, design reviews, product reviews and build/test reviews
  • Execute design, research and development activities consistent with Customer quality, cost and schedule requirements
  • Provide estimates of labor hours and material dollars required to accomplish design, research and development activities
  • Assist in root cause analysis of issues arising from experiments and engineering unit testing


  • Punctuality to work each day and prepared to work scheduled work hours
  • Other duties as assigned


  • Responsible for thoughtful adherence to all SNC Policies, Procedures, and Compliance regulations (internal and external)


  • Minimum physical requirements to perform all duties and responsibilities, as defined by management
  • SNC job descriptions are meant as summarizations only. They do not necessarily reflect all duties and responsibilities of a position

  • 5+ years’ experience.
  • Strong analytical, planning, presentation and interpersonal communication skills are required
  • In-depth knowledge and understanding of microsystem and nanosystem physics, design and engineering inclusive of mechanical systems, electrical systems, and/or thermal-fluid systems,
  • Experience in design, fabrication and testing prototypes
  • Documented record of accomplishments in the relevant field
  • Proven ability to solve complex analytical problems and provide solutions that meet technical objectives
  • Minimum Fundamental Knowledge, Skills, and Abilities as stated in SNC’s Responsibility Matrix.


  • PhD degree in physics, chemistry, materials science, electrical engineering, or a closely related discipline
  • Demonstrated ability to work with abstract concepts and use solid classical and quantum physics-based approaches to formulate physical models and apply them to current chemical, mechanical and/or engineering applications
  • Experience analyzing, designing, modeling, correlating and testing lower technology readiness level thermal-to-electrical energy conversion systems
  • Experience analyzing, designing, modeling, correlating and testing lower technology readiness level power and energy focused microsystem and nanosystem
