  • Configure and program FPGAs
     

• Support existing AMB hardware designs                                             

  • Manage, through research and validation, critical component substitutions as they become obsolete or otherwise unavailable

  • Investigate root cause failures for production and fielded components and for complex PCBAs and develop countermeasures

  • Update PCBA designs to reduce cost and improve reliability and performance

  • Support PCBA contract manufacturers via technical consultation and documentation updates
     

• Serve as technical interface with third parties:                                  

  • PCBA contract manufacturers including automated test development.
