RF Engineer

Quick Facts

• Role: Design, implement, and verify analog and RF circuits and subsystems (DC to low‑GHz)
• Work includes power stage design, simulations, prototype tuning, RF/analog measurements, documentation, and technical support

Description

You will be responsible for the end-to-end design and verification of analog and RF circuits and subsystems in the DC to low‑GHz range, including the design of the required power sections. You will optimize RF signal routing parameters, tune functional prototypes, run measurements, and create and interpret technical documentation throughout the development cycle. You will collaborate with PCB, HW, FW, test, and production teams during integration and tuning.

Responsibilities

• Independently design RF and analog HW and perform parametric optimization
• Create RF schematic designs and analog blocks, including bias points and power structures
• Simulate RF and analog circuits, optimize parameters, and evaluate results
• Design impedance matching networks, filters, and RF signal paths
• Design PCBs considering high-frequency routing rules, impedance control, and shielding
• Measure, calibrate, and tune RF and analog prototypes
• Analyze and diagnose issues and parametric deviations
• Produce and interpret measurement reports and technical documentation
• Coordinate with PCB/HW/FW/test teams during system integration and tuning
• Cooperate with production and design teams
• Create, maintain, and review development and manufacturing documentation

Requirements

• Knowledge of RF and analog circuit principles (amplifiers, mixers, filters, PLL, oscillators)
• Knowledge of PCB design for high-frequency traces, impedance control, and shielding
• Ability to work independently and in a team
• Diligence, reliability, and willingness to learn quickly
• Ability to read and write technical English

Benefits

• 25 days of vacation + additional time between Christmas holidays
• Flexible working hours with fixed core time 9:00–14:30
• Meal allowance
• Cafeteria benefits (12,000 CZK per year via Benefit Plus)
• Company events, annual bonus, and referral bonus for recommending a new employee
