Sr. Systems Engineer

Job Purpose:

Navitas Semiconductor (Nasdaq: NVTS) is a next-generation power semiconductor leader driving innovation in gallium nitride (GaN) and high-voltage silicon carbide (SiC) technologies. Our products enable faster, more efficient power delivery across AI data centers, high-performance computing, energy and grid infrastructure, and industrial electrification.

With more than 30 years of combined expertise in wide bandgap technologies, GaNFast™ power ICs integrate GaN power, drive, control, sensing, and protection, delivering faster power delivery, higher system density, and greater efficiency. GeneSiC™ high-voltage SiC devices leverage patented trench-assisted planar technology to provide industry-leading voltage capability, efficiency, and reliability for medium-voltage grid and infrastructure applications.

We are seeking a hands-on Senior Systems Engineer to join our fast-growing, collaborative team. The ideal candidate is self-motivated, energetic, and able to thrive in a high-growth, innovative environment, contributing directly to technologies that are shaping the future of power electronics. This is a key technical expert position for engineers who have successfully taken power semiconductor devices and ICs into high-volume production and want to shape future architectures.

Key Responsibilities and Duties:

• Develop power system specifications, requirements, and validation plans.

• Lead power topology evaluation, tradeoff analysis, and system optimization for efficiency, power density, cost, and reliability.

• Collaborate with IC design, magnetics, packaging, thermal, firmware, and applications teams.

• Perform modeling and simulation using tools such as PLECS, SIMetrix, MATLAB

• Analyze system performance including efficiency, transient response, EMI, thermal behavior, and fault protection.

• Support product bring-up, debugging, characterization, and customer deployments.

• Support development of application notes, test reports, and internal documentation.

• Provide technical support to FAEs and internal teams as part of customer enablement activities.

• Collaborate with R&D, product marketing, quality, and operations teams on customer programs and product development.
