- Low-power RF receive systems: filtering, amplification, signal conditioning, and integration with antennas and antenna arrays.
- High-power RF transmit systems: power amplification, impedance matching, transmission lines, protection systems, and integration with antennas and antenna arrays.
Your primary responsibility is the end-to-end analog RF subsystem: you own its design and performance, and dive into individual components whenever required to improve the whole. You will have the freedom and responsibility to investigate problems deeply and turn engineering insight into measurable improvements in real systems.
RF problems rarely exist in isolation: antenna impedance affects the power amplifier, amplifier nonlinearities affect signal quality, and receiver characteristics interact with algorithms. You will develop design choices iteratively, moving from physical understanding and equations to models or simulations, then experiments, measurements and validation. Real system data will help you uncover effects that models miss and turn the results into system improvements.
You will work closely with system, algorithm, digital hardware, software and test engineers, translating system objectives into RF requirements and measurement results into engineering decisions. The team brings deep experience across these disciplines, with support from specialist teams across Optiver. We move quickly, debate ideas openly regardless of who proposed them, and treat every result as a team result.
