Job Description

About the Role

We're looking for a Quartz Crystal Resonator Design Engineer to develop, model, and optimize quartz-based frequency control devices. You'll work hands-on with design, simulation, and testing to improve resonator performance, stability, and manufacturability.

What You'll Do

• Design AT-cut, SC-cut, and other quartz crystal resonators to meet frequency, temperature stability, and aging requirements

• Build equivalent circuit models (e.g., Butterworth-Van Dyke) and simulate resonator performance

• Partner with manufacturing to optimize blank processing, electrode deposition, and mounting techniques

• Test and characterize frequency response, Q-factor, ESR, and temperature coefficients

• Analyze the effects of vibration, shock, and environmental conditions on performance

• Support failure analysis and continuous improvement efforts

• Work with oscillator design teams to integrate resonators into circuits

What You'll Bring

• Bachelor's degree in Electrical Engineering, Physics, Materials Science, or a 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 such as network analyzers and impedance analyzers

• Familiarity with equivalent circuit models and simulation tools

• Ability to interpret and create technical drawings and specifications

Nice to Have

• SC-cut crystal design experience for high-stability applications

• Knowledge of crystal growth, cutting, lapping, and plating processes

• Familiarity with oscillator circuit design and phase noise

• Background in aerospace, defense, or telecom applications

• Exposure to environmental and reliability testing standards (MIL-STD, QPL)

What We Offer

• Health, dental, and vision insurance

• 401(k) with company match

• Vacation, holiday, and sick time

Work Environment

• A mix of lab, office, and manufacturing floor, with occasional travel to suppliers or customer sites.
