What is the difference between Senior R&D Design Engineer vs Mechanical Design Engineer?

AspectSenior R&D Design EngineerMechanical Design Engineer
CredentialsBachelor's or Master's in Mechanical Engineering or related field; experience in R&DBachelor's or Master's in Mechanical Engineering or related field
Work EnvironmentResearch labs, innovation centers, product development teamsDesign offices, manufacturing facilities, product development teams
Industry UsageUsed in companies focusing on product innovation and researchUsed across manufacturing, automotive, aerospace, and consumer products
Comparison Search IntentUnderstanding advanced R&D roles and responsibilitiesFocus on mechanical design tasks and technical skills

The main difference is that a Senior R&D Design Engineer focuses on innovative research and development projects, often leading new product concepts, while a Mechanical Design Engineer primarily concentrates on designing and developing mechanical components and systems. Both roles require strong engineering credentials, but the Senior R&D role emphasizes research, experimentation, and innovation within a collaborative environment.

About the role

This position sits within the core Engineering R&D group focused on our Solid-State Transformer (SST) platform. Our team is responsible for defining and delivering the next-generation power module, with higher power density to reduce footprint and thermal load. We're looking for a technically deep power electronics engineer focused on increasing efficiency while reducing cost per watt.

What You Will Do

  • Design and develop power conversion circuits and magnetics for the SST platform, optimizing for power density, efficiency, and thermal performance
  • Evaluate and integrate advanced power semiconductor devices (particularly, GaN) and planar magnetics to increase power throughput while shrinking module footprint
  • Translate modeling and simulation results into benchtop prototypes, and reconcile differences between predicted and measured performance
  • Drive design trade-offs across power density, efficiency, thermal management, and cost per watt to meet next-generation product targets
  • Co-design with mechanical and thermal engineering to jointly optimize packaging, cooling, and power density, and collaborate with controls engineering to integrate power modules into the SST platform
  • Lead root-cause analysis and design iteration based on test data to continuously improve power density and reliability

Who You Are And What You Bring

  • M.S. or Ph.D. in Electrical Engineering
  • 4+ years of nonacademic experience for Ph.D. candidates (6+ years for M.S. candidates), with greater experience expected for Senior Staff-level candidates
  • Hands-on experience in designing power electronics, particularly if focused on power density
  • Ability to translate modeling and simulation to benchtop performance and be able to reconcile differences between theory and practice
  • Familiarity with advanced power semiconductor devices and magnetics (particularly planar transformers)
  • Experience co-designing power electronics with mechanical and thermal engineering teams, balancing electrical performance against packaging and cooling constraints
  • Ability to lead technical execution of significant power electronics designs with a high degree of autonomy, escalating major trade-offs as needed
  • Experience mentoring less experienced engineers and contributing to technical design reviews within the team

The base salary range for this position in Petaluma,CA is $105,000 to $210,600and may vary based on experience, skills, and location.

The base salary range for this position in Austin, TX is $90,000 to $172,800and may vary based on experience, skills, and location.

This position is also eligible for bonus, equity, and benefits, with final compensation determinedin accordance withapplicable laws and internal equity.
