We are seeking a Sr. Staff  Applications Engineer with deep expertise in power electronics and power management systems to support Renesas’ India‑focused growth initiatives. This role is hands‑on, customer‑facing, and technically authoritative. 

The successful candidate will act as the technical backbone between customers, field teams, and internal design groups, owning application architecture, reference designs, competitive analysis, validation methodology, and critical customer debug. This role strongly influences product P&L or roadmap decisions through real system insight. 

You will be expected to operate autonomously, mentor other applications engineers, and represent Renesas as a trusted technical authority at key customer engagements 

Responsibilities :

• Customer‑Facing Applications Leadership 

• Serve as the primary technical interface for key customers in power-related applications (industrial, automotive light EV, inverter/UPS, consumer power, energy storage). 

• Lead design‑in, bring‑up, and debug activities at customer sites or Renesas labs. 

• Diagnose complex system‑level issues across power stage, control loop, sensing, firmware interaction, EMI/thermal behaviour. 

• Provide structured technical feedback to product and design teams based on real customer usage. 

• Reference Designs & Application Enablement 

• Architect and develop reference designs, evaluation platforms, and application demonstrators using Renesas power products (e.g., MOSFETs, DC/DC, PMICs, gate drivers, BMS ICs). 

• Own schematic review, component selection, PCB guidance, and layout best‑practice recommendations. 

• Generate application notes, design guides, and technical collateral that materially improve customer adoption. 

• Define validation plans that reflect real-world corner cases, not just datasheet conditions. 

• System‑Level Technical Expertise 

• Understand and analyse full power system behaviour, including:  

• Control loop stability and transient response 

• Thermal and efficiency trade‑offs 

• Protection mechanisms and fault behaviour 

• Interaction with MCUs/SoCs and firmware 

• Perform and guide system modelling and simulation (SIMPLIS, PLECS, SPICE). 

• Evaluate design trade‑offs and clearly articulate why one solution works better than another keeping BOM cost in mind 

• Lab Ownership & Technical Depth 

• Hands‑on operation of lab equipment: oscilloscopes, Bode/network analysers, electronic loads, power supplies, thermal setups. 

• Develop automation scripts (Python/C) to accelerate validation and characterization. 

• Support failure analysis and root cause investigation for field issues and RMA trends. 

• Technical Leadership & Mentorship 

• Act as a technical mentor for junior and mid‑level applications engineers. 

• Help define best practices, review standards, and debug methodologies across the power applications team. 

• Influence hiring by helping assess deep technical capability (not surface‑level
