Senior Field Applications Engineer

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.

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.

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.

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 is a strategic growth area within the portfolio. The candidate will promote and technically support the Company’s 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.

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 customer’s power-hardware and firmware teams and the Company’s internal firmware resources; attach controller content to power opportunities and feed customer requirements and gaps back to the responsible Business Units.

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.

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.

Sound command of power electronics fundamentals and switching power supply design theory.

Demonstrated hands-on design or support experience in one or more of: non-isolated DC-DC converters (buck, boost, buck-boost); isolated converters (flyback, forward); AC-DC power supplies; battery-powered systems; motor control applications.

Working familiarity with power MOSFET and gate driver selection and gate-drive circuit design; power management integrated circuits; analog circuit design including signal conditioning and current sensing; feedback loop design and compensation; EMI/EMC fundamentals and mitigation; and thermal management.

Familiarity with RF power as a discipline separate from switch-mode power conversion — RF power transistors and amplifier stages, their pulsed and continuous-wave ratings, gain, efficiency and linearity trade-offs, bias arrangements and sequencing, load mismatch ruggedness, and thermal design. Full RF system, transceiver or antenna design expertise is not required.

Proven competence with laboratory instrumentation — oscilloscopes, power analysers, electronic loads, function generators and programmable DC supplies.

Diploma, Bachelor’s or Master’s degree in Electrical, Electronics, Electrical & Electronics, or Power Electronics Engineering.

Minimum five (5) years of relevant experience in power electronics design, switch-mode power supply development, hardware design, application engineering, technical support or field applications engineering.

Strong analytical and structured troubleshooting capability, with excellent written and verbal communication skills.

Demonstrated ability to prepare and deliver technical presentations, training sessions and seminars, and to present confidently to both engineering and management audiences, including larger public forums.

Ability to work independently across multiple concurrent customer engagements within a cross-functional, multi-site organisation, and willingness to travel within the region for customer visits, technical support and training.

Achievement of assigned design-win and revenue targets, including growth of silicon carbide activity in the territory.

Conversion of supported design wins into qualified designs released to volume production, the time taken to get there, and timely closure of qualification findings and production issues.

Attachment of complementary Analog, Timing, RF power and controller content; reach of training and seminars delivered.
