Position Overview

Fusion Innovation is seeking an Expert RF Systems Engineer to serve as a senior technical advisor for wireless communication systems. This role develops, validates, and optimizes RF link budgets, translates system requirements into quantitative performance models, and provides recommendations that inform architecture, design, deployment, and operational decisions. You will collaborate with RF, antenna, systems, network, hardware, software, and field engineering teams to meet coverage, capacity, availability, reliability, and performance objectives.

Key Responsibilities

• Develop comprehensive uplink and downlink RF link budgets for terrestrial, satellite, cellular, private wireless, tactical, or other wireless communication systems.
• Calculate and validate transmit power and EIRP; receiver sensitivity; antenna gain; cable, connector, feeder, and implementation losses; free-space path loss; atmospheric and environmental losses; fading, shadowing, and polarization losses.
• Analyze noise figure, system noise temperature, thermal noise, noise bandwidth, receiver G/T where applicable, carrier-to-noise ratio (C/N), carrier-to-interference-plus-noise ratio (C/(I+N)), Eb/N₀, and required versus available link margin.
• Model performance across frequency bands, modulation schemes, bandwidths, antenna configurations, propagation environments, and operating conditions.
• Perform best-case, nominal, worst-case, and statistical analyses; establish engineering margins aligned with availability and reliability requirements.
• Identify link-margin limitations, assess propagation and interference impacts, and determine the parameters with the greatest influence on system performance.
• Conduct trade studies involving transmit power, antenna gain, receiver performance, bandwidth, coding and modulation, frequency selection, and deployment configuration.
• Independently review and validate complex RF analyses and communicate recommendations to multidisciplinary engineering teams.
