Senior Communications Systems Engineer – Satellite & NTN

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.

Requirements

• 5+ years of experience in wireless systems engineering, focusing on RF/PHY, signal processing, and RAN architecture.
• Deep understanding of OFDM, MIMO systems, beamforming, and wireless communication theory across both baseband and RF domains.
• , C/C++, or Python.
• Proven experience with LEO satellite constellation link budgets, payload architecture, and satellite channel modeling.

Education

Master’s or PhD in Telecommunications, Electrical Engineering, or a related field.

Standards & Protocols

Strong knowledge of 3GPP cellular standards (LTE, 5G NR, NB-IoT) and Non-Terrestrial Network (NTN) specifications (Release 17/18+).

Simulation & Tooling

Advanced proficiency in numerical modeling and simulation using

Protocol Stack Familiarity

Solid background in higher-layer RAN protocols, including RRC, RLC, PDCP, and NAS.

This is a full time, exempt position, based out of our Santa Clara, CA location.

The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience. We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.
