Lead Constellation Design & Simulation

Lead Space Systems Engineer – Constellation Design
Remote, US

A globally recognised telecommunications and digital infrastructure organisation is building a next-generation Low Earth Orbit (LEO) satellite constellation focused on direct-to-device connectivity, broadband communications, and non-terrestrial network services. Backed by significant investment and long-term strategic vision, the programme aims to transform satellite connectivity across one of the world’s largest and fastest-growing markets.

The company is looking for a Lead Constellation Design & Simulation Engineer to take ownership of the orbital architecture, coverage modelling, and constellation performance analysis for the programme’s future satellite network.

Key Responsibilities:
 

  • Lead constellation architecture development across multiple LEO orbital shells.
  • Develop and maintain coverage, latency, throughput, and capacity simulations.
  • Close link budgets for S-band NTN and Ka-band communications systems.
  • Conduct Doppler, propagation, and interference analysis activities.
  • Run EPFD simulations and support ITU coordination activities.
  • Produce India-wide coverage models and performance validation studies.
  • Support launch planning and constellation deployment modelling.
  • Collaborate with cross-functional engineering and regulatory teams to define architecture requirements.

Requirements:
 

  • Degree in Aerospace Engineering, Physics, Electrical Engineering, or related discipline.
  • Ideally 12+ years experience in LEO/MEO constellation design or mission analysis.
  • Strong hands-on experience with STK, GMAT, FreeFlyer, or equivalent simulation tools.
  • Experience with satellite communications systems and link-budget analysis.
  • Strong understanding of orbital mechanics and constellation optimisation.
  • Experience supporting NGSO, NTN, or satellite network programmes.

Nice to Have:
 

  • Experience with ITU coordination and EPFD analysis.
  • Background in Ka-band FSS or S-band MSS systems.
  • Experience supporting 3GPP NTN architectures or direct-to-device systems
  • Published technical papers or research in orbital mechanics, NTN, or interference modelling.
