Job Description


Job Description:

SAIC offers an exciting and challenging opportunity to support NASA’s present and future human spaceflight programs at the NASA Johnson Space Center in Houston, Texas under the Safety and Mission Assurance Engineering (SMAEC III) Contract.  This is an exciting time to be making history with the NASA Safety & Mission Assurance (S&MA) team assuring continuous human presence on the International Space Station and returning humans to the Moon and on to Mars, safely. You will work in a collaborative environment comprised of NASA engineers, mission operations specialists, and commercial spaceflight experts. You will apply design/operations, reliability, and system modeling/data analysis knowledge/expertise PRA and HRA support to all of the JSC human space flight programs.

Specific tasks include:

·    Provide Probabilistic Risk Assessment (PRA) and Human Reliability Analysis skills to NASA in support of NASA’s human spaceflight programs including, but not limited to, the Commercial Crew, Orion Multipurpose Crewed Vehicle, Gateway, Artemis, and EVA/Human Surface Mobility Programs.

·    Develop and utilize system safety and reliability analysis; such as, hazard analysis, Failure Modes & Effects Analysis (FMEA), Reliability Block Diagram Analysis (RBDA), Fault Tolerance Analysis (FTA), Human Reliability Analysis (HRA) and PRA to assess ground support and spaceflight hardware, software, pre-launch, in-flight and post landing recovery operations to identify hazards and quantify risk of designated operations, conditions or events related to planned human spaceflight missions.

·    Perform reliability data analysis, including the collection, classification and validation of data used to model and predict the reliability of complex spaceflight systems and crew operations under extreme environmental conditions.

·    Provide system modeling and data analysis expertise to develop reliability and probabilistic risk assessment models, and the reduction and application of probability data, including development of early flight adjustment factors.

·    Coordinate with spaceflight hardware/software developers and operators to collect  failure and operations related data necessary to model spaceflight systems.

·    Provide modeling and data analysis for design and operational trade studies to support risk informed decision making.

·    Document assessment/analysis results in formal reports and present findings and recommendations to senior management.

·    Provide technical assessments of System Safety, Reliability, Availability, and Maintainability (RAM) products and processes developed/used by NASA contractors and hardware providers.


 Required Education and Experience: 

        · Bachelor's in Engineering, Science (Physics), Mathematics, or Statistics, and 15 years or more                         experience; Master's and 13 years or more experience.

       ·  Ability to generate high quality written technical reports and prepare and give high quality technical                   presentations for senior management and the customer.

       ·  Proficient in the use of Excel and other statistical tools.

       ·  Previous SAPHIRE experience.

       ·  Previous Human Reliability Analysis experience.

       ·  Previous experience performing root cause analysis.

SAIC accepts applications on an ongoing basis and there is no deadline.
