Job Title: Quartz Crystal Resonator Design Engineer
Location: Middleton, WI
Employment Type: Full-Time
About Us
Precision Devices, a division of Wi2Wi inc. is a leading manufacturer of precision frequency control components serving telecommunications, aerospace, medical, military and industrial markets. Our team specializes in high-stability quartz crystal resonators and oscillators designed for demanding environments.
Position Summary
We are seeking a skilled Quartz Crystal Resonator Design Engineer to develop, model, and optimize quartz-based frequency control devices. This role involves hands-on design, simulation, and testing of resonators for performance, stability, and manufacturability.
Key Responsibilities
Design AT-cut, SC-cut, and other quartz crystal resonators for specified frequency, temperature stability, and aging characteristics
Perform equivalent circuit modeling (e.g., Butterworth–Van Dyke model) and simulation of resonator performance
Collaborate with manufacturing to optimize crystal blank processing, electrode deposition, and mounting techniques
Conduct testing and characterization including frequency response, Q-factor, ESR, and temperature coefficients
Analyze vibration, shock, and environmental effects on resonator performance
Support failure analysis and continuous improvement efforts
Work with oscillator design teams to ensure proper integration of resonators into circuits
Required Qualifications
Bachelor’s degree in electrical engineering, Physics, Materials Science, or related field.
And/or 5 to 7 years of experience in quartz crystal resonator or frequency control device design
Strong understanding of piezoelectric materials and resonator physics
Experience with RF measurement tools (network analyzers, impedance analyzers)
Familiarity with equivalent circuit models and simulation tools
Ability to interpret and generate technical drawings and specifications
Preferred Qualifications
Experience with SC-cut crystal design for high-stability applications
Knowledge of crystal growth, cutting, lapping, and plating processes
Familiarity with oscillator circuit design and phase noise considerations
Experience in aerospace, defense, or telecom applications
Exposure to environmental and reliability testing standards (MIL-STD, QPL)
Compensation & Benefits
Health, dental, and vision insurance
401(k) with company match
Vacation, holiday, and sick hours
Work Environment
Combination of lab, office, and manufacturing floor
Occasional travel to suppliers or customer sites
How to Apply
