About this role
What is the role?
As a Senior Constellation Modeling and Simulations 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.
This position will report to the Head of Simulations and will work closely with the engineering and regulatory team. This position will be based in Los Gatos, CA.
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.
Please note that some additional hours may be required to support project timelines
