Description: Job Title: Sr. Principal Power Supply Designer (Relocation assistance will be provided to candidates outside the posted locations)
Job Code: SAS20231904-99844
Job Location: Palm Bay, FL or Ft Wayne, IN
Job Description:
The Power Supply Design Engineer will be responsible for specification, design, analysis and testing of GaN-based power supplies for avionics and spaceborne applications.
Essential Functions:

• 
  
• Provide program support, including mission/requirements definition, concept generation and trade studies.
  
• Perform system, sub-system, circuit card assembly (CCA) design of GaN-based power supply circuits, including development from preliminary concept to final design. Specific tasks include schematic diagram generation, component selections, modeling and simulation, circuit analysis, testing, evaluation and integration support.
  
• Effectively address specific design considerations and apply best design practices relevant to GaN power switching components:
  
  • 
    
  • Device biasing, driving, and stability through all quadrants of operation
    
  • Switching and conduction losses modeling, simulation, empirical measurement
    
  • Device paralleling and current sharing
    
  • Key layout practices to minimize and balance undesired parasitics (minimizing loop size, magnetic flux cancellation, gate trace and source return symmetry strategies)
    
  • Thermal considerations and management
    
  • Mounting considerations and galvanic isolation
    
  • EMI/EMC design considerations and problem resolution.
    
  • Produce technical documentation: including review materials for Customers, performance requirement specifications, test plans, and analysis reports.
    
  • Lead or support internal and external Design reviews, including Milestone events.
    
  • Perform Worst Case analyses (WCAs); support root cause corrective actions (RCCAs) and Failure Review boards (FRB).
    
  • Collaborate with manufacturing operation for fabrication in a program team environment.
    
  • Work independently or lead a small team of designers.
    
    
    
    Qualifications:
    
    • 
      
    • Bachelor's Degree with at least 9 years of relevant experience, OR a Graduate Degree with at least 7 years of relevant experience.
      
    • 7+ years of experience interpreting high level requirements to develop GaN-based power solutions.
      
    • 7+ years of experience in the design, development, test, evaluation and troubleshooting of GaN-based power converters.
      
    • 7+ years of experience of detailed power converter design across multiple topologies; GaN device characteristics, control loop theory, thermal management, custom magnetics design, PWB layout best practices and EMI filtering.
      
      Preferred Additional Skills:
      
      • 
        
      • Active TS/SCI clearance.
        
      • Experience with SPICE, MathCAD, Matlab, Simulink, Allegro and MentorGraphics tools.
        
      • Extensive discrete power supply design experience with GaN power switching components implemented across different topologies of AC/DC and DC/DC power converters (both isolated and non-isolated) that meet power and EMI/EMC requirements described under MIL-STD-1275, MIL-STD-704, MIL-STD-461, and DO-160.
        
      • Experience with Root Cause Corrective Actions (RCCA) and Failure Review Boards (FRB).
        
      • Experience leading teams and project designs.
        
      • Strong communication skills and the ability to work in a multi-disciplinary team environment
        
      • Demonstrated effective collaboration across all levels of organizational Leadership.
