The Role
Lead communications systems modeling and RF analysis for LEO satellite and NTN systems. Responsibilities include link budgets, channel propagation, antenna and payload modeling, network performance optimization, subsystem integration, test planning, root-cause analysis, technical documentation, and cross-functional engineering coordination. The role requires expertise in wireless systems, RF/PHY, signal processing, RAN architecture, 3GPP standards, satellite communications, and MATLAB, C/C++, or Python simulation.

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!
E-Space is bridging Earth and space to enable hyper-scaled deployments of space-powered Internet of Things (IoT) solutions and services. We are fundamentally changing the design, economics, manufacturing, coverage limitations and service delivery associated with traditional satellite and terrestrial IoT systems.
By building a highly-advanced low Earth orbit (LEO) space system—with a unique antenna design, highly sustainable spacecraft system and low-cost, small portable end-user devices—we can extend global satellite coverage, capacity and connectivity beyond legacy space services to provide a new kind of IoT platform that lets users sense, track, connect and act on information gathered, anywhere.
We’re intentional, we’re unapologetically curious and we’re 100% committed to saving space, protecting our planet and turning connectivity into actionable intelligence.
As a Senior Communications Systems Engineer, you will be a critical member of the Autonomous Flight Systems and Simulations Team building highly accurate models of the spacecraft and space environments. You will enjoy large complex problems with multi-agent contributions to determine specific and probabilistic results. Your background will include either a first principles understanding of spacecraft guidance navigation and control mechanisms and forces, or radio frequency engineering and modeling.
Key Responsibilities
- 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.
- 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.
- 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.
