Principal Design Engineer

Job Details: Job Location: Torrance, CA 90503, Position Type: Full Time, Salary Range: $190,000.00 - $230,000.00 Salary/year, Job Purpose: Navitas Semiconductor is seeking a highly motivated and experienced analog / power IC design engineer to lead the architecture, design, and silicon execution of next-generation power management ICs. This role is hands-on and technical, with end-to-end ownership from concept through production, and close collaboration with systems, device, layout, and validation teams. This is a key technical expert position for engineers who have successfully brought power ICs into high-volume production and want to shape future architectures.

Key Responsibilities and Duties:

• Lead the architecture, design, and verification of power management ICs from transistor-level blocks to full top-level integration.
• Define and evaluate system-level trade-offs for next-generation power supplies in collaboration with applications and systems teams.
• Drive IC architecture decisions for products including AC-DC, DC-DC, ACF, LLC, QR, and related power topologies.
• Interface closely with device, modeling, and EDA teams to optimize device selection, models, and simulation methodologies.
• Guide and review physical layout and floor planning, providing clear feedback to ensure optimal performance, reliability, and manufacturability.
• Own tape-out execution, ensuring designs meet performance, schedule, and quality requirements.
• Lead silicon bring-up, lab validation, debugging, and correlation versus simulation.
• Support yield improvement, failure analysis, and release to production.
• Mentor junior designers and contribute to best practices across the design organization.

Qualifications: Knowledge, Skills, Abilities, and Other Characteristics (KSAO’s)

• Proven experience as chip lead or technical owner on at least one successful silicon program.
• Demonstrated track record of delivering power ICs from concept to high-volume production, including:
  • Architecture definition
  • Circuit design
  • Layout supervision
  • Post-extraction verification
  • Lab characterization and debug
  • Yield and failure analysis support
• Strong experience in AC-DC and/or DC-DC power IC design.
• Deep expertise in analog and mixed-signal building blocks such as:
  • Bandgap references
  • LDOs
  • Comparators
  • Charge pumps
  • Operational amplifiers
• Clear written and verbal communication skills.
• Self-motivated, collaborative, and comfortable working in a fast-paced, startup-like environment.

Required Qualifications Basic

• Degree in Electrical Engineering, Material Science, Applied Physics or related Fields
• Strong understanding of semiconductor device physics, SOA, and power transistors used in high-frequency switching.
• Solid knowledge of silicon fabrication processes and their impact on device models and circuit performance.

Preferred:

• MSEE + 7+ years or PhD + 5+ years of industry experience in analog or mixed-signal IC design.
• Proficiency with EDA tools, including:
  • Cadence Virtuoso / Spectre
  • Post-parasitic extraction simulation
  • Monte Carlo and corner analysis
• Experience with DFT methodologies, characterization strategies, and production test planning.
• Hands-on lab experience with silicon validation, debug, and characterization.

What We Give:

• A high visibility opportunity to work on leading edge technology development with a mission to make the world better with advancing the technology that powers the future.
• Fast decision making and freedom to work on interesting problems that the world cares about.
• A mission to succeed with full support from management.
• Health, dental, and vision benefits, unlimited PTO
• Total Compensation includes base + bonus and stock awards, depending on experience
