Job Location: Carlsbad, CA/San Diego, CA
Job Schedule: 9/80- employees work 9 out of 14 days- totaling 80 hours worked- and have every other Friday off
Job Description:
At L3Harris, innovation and mission come together. We are seeking a Senior Specialist RF/Wireless Engineer to help design and deliver advanced, mission-critical RF hardware solutions for military communications systems supporting the warfighter.
As a senior technical contributor, you will apply your expertise in RF and microwave design to develop high-performance hardware for challenging defense applications. You will be responsible for architecting, designing, and supporting the development of key RF subsystems and circuitry that are essential to reliable communication in complex operational environments.
Essential Functions:
Lead the development of RF architectures and hardware designs for communication systems, translating system requirements into effective circuit card, module, and subsystem-level solutions.
Conduct and support circuit card and subsystem development activities and design reviews, including translating customer and system requirements into RF hardware implementations.
Contribute to proposal efforts and program execution by developing technical approaches, identifying risks, estimating budgets and schedules, and recommending practical RF architecture solutions.
Perform RF/analog design, analysis, modeling, simulation, integration, and verification of high-frequency and microwave hardware at the component, subsystem, and system levels.
Collaborate across systems, mechanical, and software engineering disciplines to develop integrated solutions that meet technical, performance, quality, and manufacturability objectives.
Provide technical leadership through peer design reviews, verification test support, and guidance of RF hardware designs through development, production, and sustainment.
Manage technical tasking, schedules, and priorities for assigned efforts across the product lifecycle, supporting concept development, qualification, production, and sustainment.
Mentor and guide less-experienced engineers while promoting innovation, sound engineering judgment, and successful program execution.
Prepare and deliver technical presentations on concepts, designs, analyses, and results to engineering, program, and leadership teams to support decision-making and continuous improvement.
Maintain the ability to obtain a U.S. Security Clearance; an active clearance is preferred.
Qualifications
Bachelor’s Degree and minimum 6 years of prior relevant experience. Graduate Degree and a minimum of 4 years of prior related experience. In lieu of a degree, minimum of 10 years of prior related experience.
Preferred Additional Skills
Hands-on experience with lab equipment, including oscilloscopes, spectrum analyzers, receivers, signal generators, amplifiers, antennas, and power meters.
Strong foundation in electromagnetics, RF/microwave theory, and electronic warfare.
Ability to work independently and provide technical guidance to multi-disciplinary teams in the development of RF systems and assemblies.
Experience designing RF products from UHF through E-band, including frequency synthesizers, up/down converters, front-end electronics, antenna tracking electronics, and complete RF systems.
Experience with Cadence AWR/Microwave Office, PathWave RF Synthesis (Genesys), and Siemens EDA (Mentor Graphics) or similar tools.
Strong understanding of passive and active RF components, including amplifiers, oscillators, attenuators, mixers, and filters, and their impact on system performance.
Working knowledge of S-parameters, matching networks, cascade analysis, gain budgets, noise figure, linearity, filtering, and related RF metrics.
Strong understanding of noise figure, noise temperature, Eb/No, BER, receiver sensitivity, temperature effects, impedance interfaces, and isolation requirements.
Experience supporting RF architecture definition, developing link budgets, and performing system-level analysis.
Knowledge of nonlinear RF effects, including intermodulation, IP2, IP3, group delay variation, dynamic range, and mitigation techniques.
Understanding of power budgets and environmental design impacts.
Awareness of industry trends and emerging technologies, with the ability to support technology roadmaps that improve capability while reducing cost, size, weight, and power.
Familiarity with military and commercial SATCOM standards.
In compliance with pay transparency requirements, the salary range for this role in California, Connecticut, Massachusetts, New Jersey, Washington, and the Greater D.C. area, Denver, or NYC areas is $111,500-$207,500.
