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

• Author and maintain device specifications for assigned new products and
  derivatives. Drive them through defined milestones, capturing product
  goals, key features, specifications, and application requirements.
  
• Translate customer needs, market input, and application use cases into
  clear requirements and key specification parameters, including the specs
  that can't be compromised.
  
• Work with design engineering during early specification phases to evaluate
  architecture trade-offs and refine block-level definitions.
  

• Perform hands-on application-level evaluation of new silicon, testing
  device functionality in real-world use cases and reference circuits from
  the customer's perspective. Feed findings back to design, validation, and
  product teams ahead of release.
  
• Design, review, and bring up reference and evaluation hardware, with a
  focus on complete signal-chain solutions (sensor front end, amplification,
  reference, conversion).
  
• Develop application collateral: application notes, design guides,
  reference designs, and evaluation board documentation. Support
  simulation-model releases (SPICE macromodels, behavioral models) for
  accuracy in application use.
  
• Write and review datasheets and spec-derived collateral for technical
  accuracy and consistency ahead of product release.
  

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

Requirements/Qualifications:

• 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-load
    behavior
    
  • 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 precision
  signal-chain design (for example, how amplifier and reference choices
  affect 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 and
  design verification
  
• Strong written and verbal communication skills, including technical
  documentation such as datasheets and application notes
  
• Able to manage multiple projects, work independently, and collaborate
  across teams
  

• Depth in both linear/analog and data converters
  
• Embedded programming for MCU-based device evaluation over standard serial
  interfaces (e.g., SPI, QSPI, I2C, I3C)
  
• Data analysis or lab automation (Python, MATLAB)
  
• Analog mixed-mode simulation (AMS), behavioral modeling, or SPICE
  macromodel development
  
• Direct technical engagement with customers (design-in support,
  requirements discovery, training)
  
• Published application notes or articles, or experience delivering
  technical workshops
  
• Domain knowledge in an end market such as industrial, energy metering,
  medical, or automotive
