Job Description:

Microchip Technology is seeking an experienced Field Applications Engineer to serve as the principal technical interface between the Company its customers distribution partners the sales organisation and the Business Units across the India region. The successful candidate will drive design wins and revenue growth across the Power Electronics portfolio and will be expected to develop a working knowledge of the Companys wider offering Analog Timing and the 8- 16- and 32-bit microcontroller and digital signal controller families together with the RF power portfolio which is a separate discipline in its own right so as to position complete system-level solutions rather than discrete component sales.

The primary role of the Field Applications Engineer is to support the customer technically throughout the design cycle and in particular during validation and qualification and the release of the design into volume production. Early engagement secures the design win; revenue is realised only once the design is qualified and in mass manufacture. The candidate is therefore expected to remain engaged and accountable at every stage resolving qualification findings supporting the production ramp and sustaining the design after release.

Principal Responsibilities

Design-Win Generation and Revenue Growth

• Identify develop and convert design opportunities across the Power Electronics portfolio in line with regional design-win and revenue targets maintaining an accurate pipeline with Sales and Distribution.
• Analyse customer system requirements and recommend the optimal Microchip solution set power management devices silicon and silicon carbide discretes and modules gate drivers and isolated gate drivers sensing controllers and complementary Analog and Timing products.

Technical Support Across the Design Cycle

Support shall be sustained and hands-on at every phase. Validation qualification and production release constitute the primary focus of the role; engagement continues until the design is in stable volume manufacture and thereafter for sustaining support.

• Concept to schematic topology selection system partitioning feasibility assessment device sizing and derating bill-of-materials proposal control-loop and compensation review protection and power-sequencing review.
• PCB layout power-stage layout grounding and return-path strategy thermal- and EMI-aware component placement.
• Prototype bring-up and optimisation laboratory support first power-up fault diagnosis and improvement of efficiency thermal performance EMI/EMC transient response and reliability.
• Validation and qualification (primary focus) review of the design-verification and qualification test plan; guidance on corner-case margin life and stress testing across voltage load temperature and line; EMI/EMC pre-compliance and safety pre-screening; and joint root-cause analysis of qualification failures with the Business Unit.
• Production release and ramp (primary focus) design-for-manufacture and design-for-test review pilot-run and line bring-up resolution of production test and programming issues yield analysis field-return and failure analysis lifecycle and supply-continuity guidance and sustaining support.

Application Domain Coverage

The role spans two distinct technical domains. Switch-mode power conversion is the core of the position; RF power is a separate portfolio and a separate engineering discipline and the two are not interchangeable.

Switch-mode power conversion and motor control

• DC-DC converters (buck boost buck-boost four-switch buck-boost) and isolated topologies (flyback forward LLC resonant phase-shifted full bridge CLLC).
• AC-DC supplies and power factor correction; battery-powered systems chargers and battery management.
• Motor control drives BLDC PMSM and ACIM sensored and sensorless and industrial automotive and embedded power sub-systems.

RF power

• GaN-on-SiC HEMT RF power transistors RF power MOSFETs MMIC power amplifiers.
• Amplifier-stage support device selection for pulsed and continuous-wave duty output power gain efficiency and linearity trade-offs impedance matching and pallet integration VSWR ruggedness pulse fidelity and droop and thermal design.

Silicon Carbide and Wide Bandgap Solutions

Silicon carbide is a strategic growth area within the portfolio. The candidate will promote and technically support the Companys SiC MOSFETs Schottky barrier diodes power modules and associated gate drivers covering:

• Device selection and sizing including comparison against silicon alternatives on efficiency switching frequency thermal performance system cost and solution size.
• Gate-drive design for wide bandgap devices drive voltage and impedance negative turn-off bias isolation and common-mode transient immunity gate-loop layout with protection covering short-circuit withstand desaturation detection and soft shut-down.
• Management of high dv/dt and di/dt parasitic inductance overshoot and ringing and the resulting EMI and insulation stress; thermal design module packaging and device paralleling.
• Application support for silicon-carbide systems solar and energy-storage inverters bidirectional converters electric-vehicle on-board chargers and DC fast charging traction and industrial drives.

Collaboration with Microcontroller and Digital Signal Controller Teams

Many power designs are completed only in combination with an embedded controller. The candidate will work closely and routinely with the internal teams responsible for the 8- 16- and 32-bit microcontroller and digital signal controller families the relevant Business Units applications engineering groups and firmware development teams to deliver a complete hardware-plus-firmware solution.

• Engage those teams early in the opportunity so that controller selection peripheral capability and software availability are established alongside the power-stage architecture rather than after it.
• Support customer adoption of Microchip controller platforms with their development tools software frameworks control libraries and reference firmware and give first-level guidance on control-loop implementation ADC PWM comparator and timer configuration and firmware-hardware co-debug.
• Act as the technical bridge between the customers power-hardware and firmware teams and the Companys internal firmware resources; attach controller content to power opportunities and feed customer requirements and gaps back to the responsible Business Units.

Technical Presentations Training and Seminars

• Deliver technical presentations roadmap briefings solution pitches and design reviews to customer engineering and management audiences on site and remotely.
• Plan and conduct customer and distributor training classroom and hands-on workshops covering Microchip devices reference designs development boards software tools and laboratory exercises.
• Represent the Company as a technical speaker at seminars webinars roadshows technology days exhibitions industry conferences and academic engagements addressing audiences from a single design team to several hundred attendees.
• Prepare and maintain the supporting material presentation decks application notes block diagrams demonstration set-ups and training content keeping it current with the product roadmap.

Cross-Functional and Competitive Engagement

• Collaborate with Sales distribution partners the Analog and Power silicon carbide and controller Business Units and factory applications teams to resolve technical escalations and secure design-win objectives.
• Monitor industry trends emerging standards and competitive offerings; provide structured competitive positioning and feedback to the Business Units to influence roadmap direction.
