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 ResponsibilitiesAs 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.

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. E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.
