## 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 Constellation Modeling and Simulations Architect, 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

As the technical authority for constellation design, you will:

- Lead the development and maintenance of the overall constellation architecture and design baseline.
- Define and freeze constellation geometry to support downstream spacecraft procurement and program execution.
- Develop and validate end-to-end link budgets across both Mobile Satellite Services (MSS) and Fixed Satellite Services (FSS), considering environmental effects including rain fade and Doppler.
- Perform coverage analysis and network performance simulations to optimize service availability and capacity.
- Conduct interference and compatibility studies, including Equivalent Power Flux Density (EPFD) modelling to support regulatory compliance.
- Produce technical documentation supporting regulatory filings, constellation deployment planning and launch strategy.
- Develop long-term capacity modelling and network growth strategies.
- Collaborate with systems engineering, payload, RF, regulatory and commercial teams to optimize overall network performance.
- Provide technical leadership for constellation design activities throughout the program lifecycle.

## Basic Qualifications

- 5+ years’ experience in LEO and/or MEO satellite constellation design.
- Extensive hands-on experience using tools such as STK, GMAT, FreeFlyer or equivalent orbital analysis and simulation software.
- Proven experience developing and closing satellite communications link budgets across MSS and/or FSS systems.
- Strong understanding of orbital mechanics, constellation optimization and satellite network performance modelling.
- Direct experience supporting ITU coordination activities, including EPFD analysis and interference studies.
- Experience producing technical documentation supporting satellite system design and regulatory submissions.
- Ability to communicate complex technical concepts to multidisciplinary engineering teams and senior stakeholders.
- Postgraduate qualifications in Aerospace Engineering, Electrical Engineering, Applied Physics or a related technical discipline.

## Preferred Qualifications

- Experience working on Non-Terrestrial Networks (NTN) or next-generation satellite communications systems.
- Technical publications or recognized expertise in orbital mechanics, interference analysis or satellite communications.
- Experience supporting large-scale commercial satellite constellation programs.

## 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)
  - Acquired CommAgility (December 2022) for USD $14.5M, bringing wireless/5G expertise in-house
  - 108 active job postings — job postings up +163.4% year-over-year
  - Workforce distributed across 7 countries (US, France, Germany, UK, India, Philippines, Mexico)
  - Talent drawn from SpaceX, Thales Alenia Space, Eutelsat OneWeb, Planet, Meta, and Rakuten

## Competitive Advantages
- **Sustainability-first design**: E-Space sets a new standard in sustainable space infrastructure, actively minimizing space debris and preserving access to space — a key differentiator versus legacy LEO systems.
- **Cost disruption**: Overhauled spacecraft, antenna, and terminal design, plus a new deployment approach, lowers total satellite system costs to "a fraction of competing LEO systems."
- **Founder pedigree**: Greg Wyler is a proven space industry pioneer (O3b Networks, OneWeb), giving the company deep credibility and network access.
