  • Develop technical documentation such as design requirements, development plans, design reports, test plans, etc.
  • Execute work above to meet or exceed the established engineering and company process and procedures as well as best design guidelines
  • Provide clear communication of design and development approach or plans to technical peers, leads, and management
  • Plan and perform digital engineering research or design development assignments, including responsibility for the digital engineering of part of a major project or a project of medium complexity
  • Concisely translate product specifications into usable digital engineering data/requirements applicable to the particular assignment
  • Complete high-quality work while keeping budget and schedule constraints on track
  • Perform engineering analysis of complex digital circuits and dense mixed signal circuits
  • Perform troubleshooting failure trends in production
  • Provide analysis and technical review support during gate reviews and both internal and customer design reviews
  • Provide technical and estimation support such as basis of estimate development to proposals as directed by management
  • Timely execute work per directions from project engineer or program manager
  • Working across disciplines to ensure adoption of qualifiable designs with scalable manufacturing processes
  • Identifying development risks and mitigation strategies
  • Execute work above with minimal supervision
