## Job description

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

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.

## Basic Qualifications

- Education: Master’s or PhD in Telecommunications, Electrical Engineering, or a related field.
- Experience: 5+ years of experience in wireless systems engineering, focusing on RF/PHY, signal processing, and RAN architecture.
- Standards & Protocols: Strong knowledge of 3GPP cellular standards (LTE, 5G NR, NB-IoT) and Non-Terrestrial Network (NTN) specifications (Release 17/18+).
- Technical Mastery: Deep understanding of OFDM, MIMO systems, beamforming, and wireless communication theory across both baseband and RF domains.
- Simulation & Tooling: Advanced proficiency in numerical modeling and simulation using MATLAB, C/C++, or Python.

## Preferred Qualifications

- Satellite Systems: Proven experience with LEO satellite constellation link budgets, payload architecture, and satellite channel modeling.
- Protocol Stack Familiarity: Solid background in higher-layer RAN protocols, including RRC, RLC, PDCP, and NAS.

## About E-Space

## Company Overview
- **One-liner**: E-Space is building the world's most sustainable low Earth orbit (LEO) satellite network designed to connect billions of devices and deliver secure, real-time data and AI-driven insights anywhere on Earth.
- **Entity Type**: Private (Seed stage; $50M total funding)
- **Headquarters**: Arlington, Texas, United States
- **Founded**: 2021
- **Founders**: Greg Wyler (previously founded O3b Networks and OneWeb)

## Core Business
- **Primary industry**: Telecommunications / Space technology (LEO satellite communications)
- **Target customers**: B2B, B2G — governments, defense agencies, critical infrastructure operators, logistics & asset tracking firms, digital agriculture, and enterprise IoT customers
- **Mission**: "Make data universally available, secure and actionable anywhere on the planet."

## Products & Services
- **E-Space LEO Platform**: A low Earth orbit satellite constellation (planned 100,000+ satellites) that securely connects billions of small, easy-to-install devices anywhere on Earth. Data can be routed to data centers or processed with edge AI (AIoT) for real-time insights and automation.
- **Constellations-as-a-Service**: Enables governments and enterprises to operate, control, and monitor their own satellite systems, allowing every nation to become "spacefaring."
- **Defense & Security Solutions**: A resilient satellite system designed for defense applications, leveraging space as "the ultimate high ground."
- **Critical Infrastructure & ESG Monitoring**: Rapid-deploy connectivity for monitoring critical infrastructure and Earth's sensitive resources, positioning E-Space as an "ESG partner to the planet."

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding — USD $50M (Seed round, February 2022, led by Prime Movers Lab; additional venture round in November 2024). Annual Revenue — EUR 3.4M (estimated).
- **Notable Investors/Partners**: Prime Movers Lab (lead seed investor)
- **Growth Signals**:
  - Completed Beta-1 and Beta-2 satellite launches (execution beyond theory)
