Job DetailsJob Location: New Taipei City, TaipeiPosition Type: Full TimeJob Purpose:

Navitas Semiconductor (Nasdaq: NVTS) is a high-growth, publicly traded technology company and a world leader in next-generation GaN and SiC power semiconductors. We are seeking a Sr. Field Application Engineer based in Taiwan to drive technical design-ins and system-level architecture wins across the AI Data Center (AIDC) and high-power AC/DC markets, targeting cutting-edge server Power Supply Units (PSU), Energy Storage Systems (ESS), and high-performance compute infrastructures.

Taiwan sits at the heart of the global AI server and power supply chain, home to leading ODMs, OEM R&D centers, and power supply manufacturers driving the world’s most advanced cloud and AI hardware. This high-visibility technical role operates with significant ownership and autonomy, requiring deep, collaborative relationships with system architects, R&D engineers, and technical leadership at Taiwan’s most strategic data center and high-power accounts.

Key Responsibilities and Duties

Own and drive design-in activities from assigned Taiwan-based AC/DC PSU, DC/DC converter, and high-power laptop/workstation adapter accounts, targeting server power supplies, energy storage systems (ESS), Solid-state transformers (SST) and telecom/Industrial power modules (Bricks)
Provide comprehensive system-level guidance, including topology selection, component sizing,. Schematic and PCB layout reviews. Drive design-in activity from NPI across assigned accounts
Engage decision-makers across engineering, power architecture and executive leadership at Taiwan ODMs and dedicated PSU/adapter manufacturers
Clearly articulate and demonstrate the quantifiable value proposition of Navitas GaN and SiC solutions in terms of efficiency, power density, thermal performance, and total cost of ownership
Guide customers in migrating from legacy silicon to advanced wide-bandgap (GaN/SiC) solutions to maximize power density and efficiency in high-power applications.
Hands-On Lab Validation. Conduct rigorous lab testing and prototype bring-up. Troubleshoot and solve complex design challenges related to high-power conversion, including AC/DC control loop stability, thermal management, high-frequency magnetic design, and EMI/EMC compliance.
Cross-Functional Collaboration: Partner closely with Sales, Marketing, and internal R&D. Translate emerging customer requirements in the Server PSU and ESS markets into actionable product definitions and roadmap enhancements to support our market competitiveness.

QualificationsKnowledge, Skills, Abilities

Deep knowledge of the Taiwan PSU and power adapter supply chain ecosystem, including key ODMs, EMS providers, and standalone PSU/adapter manufacturers
Strong technical understanding of AC/DC and DC/DC power conversion topologies including PFC, LLC resonant, flyback, synchronous rectification, and totem-pole architectures
Experience and understanding of GaN and SiC power device advantages in switching frequency, efficiency, and power density for PSU and adapter applications
High degree of professional accountability, self-motivation, and the ability to champion initiatives internally and externally

Requirements

Education: Bachelor's or Master's degree (or higher) in Electrical/Electronic Engineering, with a specialized focus on Power Electronics.
Technical Experience: 7+ years of hands-on R&D or FAE experience strictly focused on designing, developing, or supporting high-power AC/DC systems (e.g., kW-class Server PSUs, Grid-tied Inverters, Bi-directional ESS, or high-density telecom bricks).
Prior experience with GaN or SiC power semiconductor companies or power conversion IC vendors is preferred
Design Capabilities: Strong practical power supply design capabilities, with solid knowledge of power performance testing specifications, safety regulations, and EMI.
Topology Mastery: Familiarity with common power topologies such as Flyback, ACF, and PFC/LLC. Mastery of standard AC-DC power circuit design and control circuit design.
Software Proficiency: Proficiency in PCB design software (e.g., Protel/Altium) and familiarity with simulation and calculation software such as SIMPLIS and Mathcad.
Language: Fluency in Mandarin Chinese; business level English proficiency

Personality & Soft Skills

Communication: Exceptional communication and presentation skills, capable of translating complex AC/DC power concepts clearly to both engineering peers and system architects.
Mindset: A resilient, "can-do" mentality with a proactive, positive thinking approach to overcoming complex technical roadblocks.
Teamwork: Highly collaborative team player who thrives in a fast-paced environment and works effectively with others to complete deliverables and achieve shared goals.
