Performs technical planning, system integration, verification and validation, cost and risk, and supportability and effectiveness analyses for total systems. Analyses are performed at all levels of total system product to include: concept, design, fabrication, test, installation, operation, maintenance and disposal. Ensures the logical and systematic conversion of customer or product requirements into total systems solutions that acknowledge technical, schedule, and cost constraints. Performs functional analysis, timeline analysis, detail trade studies, requirements allocation and interface definition studies to translate customer requirements into hardware and software specifications.

Basic Qualifications:
The Orbit Analyst/Flight Dynamics Engineer performs the following functions and analyses:
Pre-mission orbital analyses for satellite missions in a variety of orbit regimes (e.g. LEO, GEO, Cis-lunar)

Launch window analysis

Mission sequence of events definition

Propellant budgeting analyses and on-orbit fuel requirements and mission lifetime estimates

Participation in mission rehearsals to simulate orbital analysis tasks performed in operations

Maneuver planning and optimization analyses

Orbit determinations to specify tracking system parameters, define the orbital state, and predict orbital events

Plans and provides operational support for orbit transfer and station keeping maneuvers

Analyses of satellite and constellation access, coverage, lifetime, and additional trade studies

Satellite rendezvous and proximity operations planning and analyses

Concept of operations (ConOps) development

Position requires knowledge of spacecraft mission operations

Additional duties may include requirements development, writing complex specifications, interface control documents, and engineering reports from advanced studies, special engineering investigations, and similar activities. May be called on to assist in New Business activities such as conceptual design and analysis for proposals and funded studies and may include authoring sections for both.

The candidate should possess strong computing skills with familiarity with Systems Tool Kit (STK), Matlab, Python, C#, C/C++, Visual Basic, or Fortran.
