Electrical Engineer/Intern

About EltecFor over 50 years, Eltec Instruments has been a trusted U.S. manufacturer of instrumentation-grade pyroelectric infrared detectors. Our detectors convert extremely small infrared signals into clean electrical outputs used in flame detection systems, gas analyzers, medical instruments, railroad safety systems, and defense sensing platforms.At Eltec, every design decision matters — from FET selection and low-noise circuit design to PCB layout, optical filter selection, and detector packaging. If analog circuits, precision measurement, and sensor signal chains sound interesting to you, this is a role worth considering.About the RoleWe are in the middle of an active product development program and are expanding our pyroelectric detector platform into a new digital product family.The goal is to integrate Eltec’s instrumentation-grade lithium tantalate detector technology with analog front-end circuitry, digital signal processing, and a standard I²C interface so our detectors can connect more easily to modern embedded systems.This work spans analog front-end design, detector characterization, PCB layout for constrained form factors, thermal validation inside sealed metal packages, and digital interface bring-up.We are hiring for multiple levels — from summer interns to entry-level or experienced electrical engineers.What You’ll Work OnDesign, build, and test analog front-end circuits for pyroelectric infrared detectorsSet up measurement rigs and characterize detector performance, including responsivity, noise spectral density, NEP, and D*Contribute to PCB schematic capture and layout for compact mixed-signal detector electronicsConfigure and bring up digital interface circuitry, including I²C-based ADCs and embedded signal acquisitionWrite Python scripts to automate register configuration, data collection, and signal analysisTroubleshoot analog and mixed-signal circuits at the board levelDocument findings in clear engineering reports and maintain design recordsFull-time engineers will take on increasing ownership over characterization plans, PCB revision cycles, test methods, and product-level design decisions.Internship Track — Summer, PaidIdeal candidates will have:Currently pursuing a B.S. in Electrical Engineering; rising junior or senior preferredCoursework in analog circuits, signals and systems, electronics lab, or embedded systemsComfortable using basic lab instrumentation: oscilloscope, DMM, function generator, and power supplySome exposure to a schematic or PCB design toolExperience with at least one technical computing or scripting tool such as Python, MATLAB, or LabVIEWMinimum 3.0 GPA preferred; strong hands-on projects will be considered alongside GPAFull-Time Track — Experienced Ideal candidates will have:B.S. in Electrical Engineering or related fieldHands-on background in analog circuit design, sensor characterization, embedded systems, or precision measurementWorking proficiency with PCB design tools; Altium experience is preferredAbility to own a measurement task end-to-end: setup, data collection, analysis, troubleshooting, and documentationExperience with low-noise design, mixed-signal circuits, precision instrumentation, or sensor interfaces is a strong plusNice to Have — Both TracksExperience with transimpedance amplifiers, charge amplifiers, lock-in detection, or chopped/pulsed signal conditioningFamiliarity with standard digital communication protocols such as I²CExposure to infrared sensing, photonics, optics, or detector physicsExperience debugging real hardware Why EltecWork on mission-critical technology Learn real-world analog and sensor engineering challenges Learn from engineers with decades of experience in detector design, precision measurement, and infrared sensingJoin a small team where your contributions are visible, your questions get answered quickly, and your work can make it into a real productDaytona Beach, FL — competitive compensation, reasonable cost of living, and the Atlantic Ocean nearbyTo ApplySend your resume to jobs@eltecinstruments.com along with a brief note describing a circuit you have built, a measurement problem you have solved, or a hands-on engineering project you are proud of.Candidates must be authorized to work in the United States.
