Senior Advanced Systems Engineer (Remote)

APR Consulting is seeking a Senior Advanced Systems Engineer to support Space Force missile tracking and defense initiatives. The role involves designing, integrating, and analyzing complex space and ground systems, utilizing Model-Based Systems Engineering principles.

Responsibilities:

• Develop and maintain space and ground system architectures using Model-Based Systems Engineering (MBSE) principles
• Perform requirements analysis and decomposition, translating mission needs into physical, functional, and logical architecture views
• Define system architectures, system interfaces, and Interface Control Documents (ICDs)
• Develop and analyze system-level Technical Performance Measures (TPMs) to support mission effectiveness
• Define segment budgets and perform system trade studies and tradeoff analyses
• Conduct probabilistic mission analysis for space and ground systems and manage analytical models supporting system performance
• Coordinate mission performance and system design within MBSE models
• Drive interface definition based on mission-derived performance measures
• Collaborate with internal engineering teams and external customers to develop integrated system solutions
• Support system design change management and configuration coordination
• Develop system threads and Concepts of Operations (CONOPs) for space and ground architectures supporting missile tracking missions

Requirements:

• Bachelor's degree in Systems Engineering or a related Science, Engineering, Technology, or Mathematics (STEM) discipline plus a minimum of 8 years of relevant experience
• Master's degree in a related STEM field plus 6 years of relevant experience
• Strong background in systems architecture and integration for space and ground systems
• Ability to work effectively across multidisciplinary engineering teams
• Due to the nature of work performed within our facilities, U.S. citizenship is required
• Experience developing space and ground system architectures using Model-Based Systems Engineering (MBSE) methodologies
• Requirements development, allocation, and traceability management
• Architecture decomposition and interface definition
• Experience developing and analyzing Technical Performance Measures (TPMs)
• Knowledge of Telemetry, Tracking, and Command (TT&C) satellite-to-ground systems
• Experience developing and coordinating Interface Control Documents (ICDs)
• Experience with space constellation system design and operations
• Space mission design including sensing, communications, payload management, and mission data processing
• Flight dynamics management including collision avoidance, station keeping, orbit insertion, de-orbit operations, and Launch and Early Orbit Phase (LEOP) support
• Experience with orbit determination and space-to-ground contact planning
• Strong system change management and cross-functional coordination skills
• Familiarity with MagicDraw and advanced MBSE tools
• Experience with enterprise and cloud-based interfaces including REST, gRPC, Kafka, and SNMP
• Knowledge of CCSDS protocols and space communication standards
• Experience with RF and optical space communications
• Knowledge of IP networking and data archiving methods
• Experience with space ground antenna systems and OpenC3
• Familiarity with MDA programs and commercial cloud architectures
• Experience supporting automated flight dynamics operational workflows
• Exposure to AI-enabled tools such as FreeFlyer or Meridian
• Ability to support constellation situational awareness, anomaly resolution, and performance trending analysis
• Ability to produce clear, concise technical documentation supporting system development and engineering activities
• Experience working in Agile development environments
