Mission Analysis Engineer (Senior) - Millennium Space Systems

About the Position

Bring your ideas to life at Boeing's Millennium Space Systems, a part of Boeing Defense, Space and Security (BDS). We are a fast, agile small satellite company focused on national security space. Our missions have a direct impact on global security, such as missile warning and Earth observation.

The Mission Analysis Engineering team is focused on (a) design and development of Concepts of Operations (CONOPS) and Design Reference Missions (DRMs) from key customer requirements; (b) modeling and simulation of satellites, constellations, and system-of-systems; and (c) design and integration of mission data processing algorithms, such as EO/IR image processing or inertial tracking. They are key stakeholders in the design and validation of mission CONOPS and Design Reference Missions (DRM) and are leaders in comprehensive end-to-end software integration, validation, and testing.

As a Mission Analysis Engineer (Senior), you will be the Responsible Engineering Authority (REA) for all modeling, simulation, and analysis for a program, study, or proposal. You will innovate creative solutions and novel designs to improve our products and solidify Millennium as an industry leader. You will develop methods to simulate mission scenarios and assess end-to-end constellation capabilities; design and deploy image processing, inertial tracking, state estimation, and optimal control algorithms for sensor systems; and provide tools and modeling platforms for validating system performance during on-orbit mission operations.

Responsibilities

• Build and maintain simulations for large satellite constellations to assess effectiveness against mission requirements
• Own the Electro-Optical/Infrared (EO/IR) image processing algorithms chain, from photon to Warfighter
• Create models for space vehicle payloads to use in system trades and performance predictions
• Develop novel algorithms, models, and data processing schemes for MW/MT, RPO, and SDA systems
• Architect the Concepts of Operation (CONOPS)/Design Reference Mission (DRM) and their associated simulations
• Collaborate with software and firmware teams to develop platforms for simulation deployment (e.g., software/hardware-in-the-loop)
