Principal Engineer - Applications (Precision Signal Chain, Data Converters / Lin

Help define the next generation of Microchip’s precision analog and mixed-signal products. The Mixed Signal & Linear Division builds the complete precision signal chain: op amps, comparators, voltage references, current-sense amplifiers, ADCs, DACs, and digital potentiometers. One applications team supports all of it.As a Principal Applications Engineer, you’ll drive device specifications, work with design engineering on architecture trade-offs, and bring a system-level view of the customer to products that ship for 10+ years. We’re looking for depth in either precision linear/analog or data converters, and an understanding of how the two work together. Depending on your background, your initial focus will be either ADCs (primarily SAR) or linear products such as op amps, comparators, voltage references, and current-sense amplifiers. From there you’ll have room to broaden across the signal chain and a clear path to product-family ownership.The position works closely with product marketing, architecture, design engineering, product engineering, validation, and test throughout the new-product-development lifecycle. It also supports sustaining and lifecycle activities for assigned devices.Core responsibilitiesDefinition

• Author and maintain device specifications for assigned new products andderivatives. Drive them through defined milestones, capturing productgoals, key features, specifications, and application requirements.
• Translate customer needs, market input, and application use cases intoclear requirements and key specification parameters, including the specsthat can’t be compromised.
• Work with design engineering during early specification phases to evaluatearchitecture trade-offs and refine block-level definitions.

Application evaluation and system enablement

• Perform hands-on application-level evaluation of new silicon, testingdevice functionality in real-world use cases and reference circuits fromthe customer’s perspective. Feed findings back to design, validation, andproduct teams ahead of release.
• Design, review, and bring up reference and evaluation hardware, with afocus on complete signal-chain solutions (sensor front end, amplification,reference, conversion).
• Develop application collateral: application notes, design guides,reference designs, and evaluation board documentation. Supportsimulation-model releases (SPICE macromodels, behavioral models) foraccuracy in application use.
• Write and review datasheets and spec-derived collateral for technicalaccuracy and consistency ahead of product release.

Customer and team

• Resolve complex, escalated design issues with customers and fieldapplications teams.
• Deliver technical training on product operation and system-levelsignal-chain design.
• Provide technical guidance to junior applications engineers.

• BSEE, MSEE, or PhD with 10+ years of experience in analog/mixed-signal applications, design, validation, or systems engineering
• Deep hands-on expertise in at least one of the following:
• Precision linear/analog: op amps, comparators, voltage references,current-sense amplifiers. Includes stability and compensation, noise,offset and drift, input/output stage trade-offs, and capacitive-loadbehavior
• Data converters: SAR and/or delta-sigma ADCs, DACs. Includes input drive and settling, reference design, anti-aliasing, and converter metrics(INL/DNL, ENOB, SNR/SFDR/THD)
• Working knowledge of the other area as it applies to precisionsignal-chain design (for example, how amplifier and reference choicesaffect converter performance)
• Experience contributing to product requirements or device definition
• Solid bench evaluation and debug skills with standard lab instrumentation;experience with PCB design and hardware bring-up
• Proficiency with SPICE simulation and tools for circuit analysis anddesign verification
• Strong written and verbal communication skills, including technicaldocumentation such as datasheets and application notes
• Able to manage multiple projects, work independently, and collaborateacross teams, * Depth in both linear/analog and data converters
• Embedded programming for MCU-based device evaluation over standard serialinterfaces (e.g., SPI, QSPI, I2C, I3C)
• Data analysis or lab automation (Python, MATLAB)
• Analog mixed-mode simulation (AMS), behavioral modeling, or SPICEmacromodel development
• Direct technical engagement with customers (design-in support,requirements discovery, training)
• Published application notes or articles, or experience deliveringtechnical workshops
• Domain knowledge in an end market such as industrial, energy metering,medical, or automotive
