· Apply advanced astrodynamics and orbital mechanics theory to mission planning across varied orbit regimes
· Collaborate with software developers, systems engineers, contractors, and operators in an Agile development environment
· Support the Chief Mission Architect in guiding technical direction and ensuring mission execution success
· Gather and translate strategic objectives and operational concepts from customers and end-users into actionable mission solutions
Basic Qualifications:
· Experience with mission planning and execution domain
· Knowledge of spacecraft subsystems (AOCS, power, thermal, communications) and their interaction with mission-level software
· Strong background in software development and/or software architecture
· Proficiency with orbital mechanics theory, maneuver planning, and astrodynamics tools (e.g. STK, GMAT, Orekit, MATLAB/Simulink, or Python astrodynamics libraries)
· Effective oral and written communication skills and an ability to work effectively in a rapid paced, team environment
· US Citizen with Top Secret clearance
Desired Skills:
· Familiarity with Conductor or MPET applications
· Experience with operator workflow and use cases for mission planning scenarios
