Applied Technology is seeking a highly talented and technically strong individual to fulfill an RF Circuit Design Engineering role. In this technical position, the role will have unique and varied responsibilities. Candidates for this position are engineers with diverse knowledge and a wide variety of interests. As a key resource across multiple products, the successful candidate will handle tasks such as:

• Generate schematics that include RF, Analog, power circuits, interface logic, sensors, peripherals, etc.
• Create hardware designs with a focus on Discrete RF circuits, PAs, LNAs, backend, etc.
• Develop RF front ends operating from sub‑GHz up to mmWave
• Simulate circuit performance using ADS, CST, Spice, and other simulation software.
• Perform RF lineup calculation for both Rx (Noise Figure, IM, etc.) and Tx (Multiple PA technologies and modes of operation, harmonic suppression, etc).
• Design and optimize circuits for minimal current drain to maximize battery life
• Implement analog circuits (A/D & D/A converters, op‑amps, LEDs, etc), power supplies & voltage regulators
• Use schematic and layout tools (Cadence a plus) for PCB routing, high speed interface, impedance matching, power routing, etc.
• Drive product and feature requirements, architecture, design, and test strategy with customers and engineering teams
• Write test procedures, interface control documents and other documentation
• Support full product development life‑cycle: architecture, design, bring‑up, integration of initial HW/SW, factory support, test & validation, and customer support
• Seek out opinions and build trust & buy‑in across all functional teams (hardware, software, FPGA, mechanical, etc), as well as management and customers
• You must be a flexible, results‑oriented problem‑solver who requires minimal supervision. Projects can vary greatly from one to the next, so you must thrive on variety and enjoy taking on new challenges.
• You will be a member of a small (1‑6 person) multi‑disciplinary team, and will work directly and regularly with customers to develop product requirements and will communicate technical status verbally, written, and in regular customer meetings.

• Discrete RF circuit design experience required including amplifiers, transmitters, receivers, synthesizers, etc.
• 5+ years RF Circuit design experience
• Thorough understanding of RF test equipment and measurement tools, such as signal analyzers, signal generators, network analyzers, oscilloscopes, soldering stations, etc.
• Detailed understanding of RF circuits simulation tools (ADS, MATLAB, HFSS, CST, PSPICE, etc.), and lab automation (Python, Lab View).
• Experience with Schematic capture and layout tools, Cadence Allegro a plus
• Wide breadth of Hardware design preferred - including power supplies, A/D's, peripherals, batteries, charging circuits, etc
• Product & feature architecture, requirements, design, and development experience
• Understanding of Antennas - design, simulation tools…
