Senior Communications Systems Engineer – Satellite & NTN

Key Responsibilities

System Modeling & RF Analysis

• Lead comprehensive link budget analyses, RF line-up modeling, and payload trade-offs across RF and IF configurations for LEO satellite payloads.
• Model channel propagation, satellite antenna patterns, RF impairments, co-existence, and self-interference mitigation strategies.
• Analyze end-to-end network performance, optimizing system efficiency, capacity, latency, and overall network KPIs under dynamic operational conditions.

Cross-Functional Integration & Architecture

• Partner across multidisciplinary engineering teams—including PHY/MAC algorithms, RF design, digital beamforming, modem, firmware, and mechanical engineering—to ensure end-to-end system integration.
• Deep-dive into component- and subsystem-level designs to establish performance targets, evaluate test results, and resolve test failures.
• Interface between wireless communications protocols and application endpoints to ensure seamless system and network-level operations.

Validation, Quality & Execution

• Define test plans, review hardware/software designs, and drive root-cause analysis for system-level issues to ensure carrier-grade product quality.
• Document technical specifications, expectations, and architecture updates for both internal engineering teams and external partners.
• Communicate project status, technical risks, and trade-off decisions clearly across development teams and management.
