Mission Architect (Remote Sensing) - Millennium Space Systems
Company:
Millennium Space SystemsMillennium Space Systems, a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation.
Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen.
Millennium programs are reshaping the future Overhead Persistent Infrared (OPIR) enterprise for National Security Space customers, focusing on smaller, proliferated, and resilient systems across multiple mission areas. Millennium is establishing a resilient missile warning architecture that adds capability to global detection, warning and precision tracking of advanced threats, including hypersonic missile systems.
As a Mission Architect, you will be an OPIR Subject Matter Expert (SME), overseeing mission architecture and spacecraft/constellation design across one or more programs. You will oversee all aspects of designing, developing, and fielding Remote Sensing (RS) space segments, including integration with ground and user segments. You will design and develop modeling and simulation tools and methods to validate mission scenarios and assess end-to-end system performance against Key Performance Parameters (KPPs).
You will be responsible for assessing sensor design, development, and performance, conducting solution trades, and decomposing requirements for payload and algorithm vendors. You will be integral to writing proposals, requirements definition, system design, integration & test, and on-orbit operations.
Position Responsibilities:
Define architecture and system requirements for OPIR missions
Lead modeling and simulation efforts to assess system performance
Develop CONOPS at the spacecraft, constellation, and mission level
Architect and implement Mission Data Processing (MDP) algorithms (onboard and ground-based)
Oversee mission level budgets and KPPs (e.g. LOS knowledge, jitter/smear, optical transmission, latency, etc.)
Ensure space system (including Electro-Optical/Infrared (EO/IR) payloads and bus components) meet mission level requirements
Basic Qualifications (Required Skills/Experience):
Bachelor's Degree in engineering or the physical sciences / computer science and 14+ years of experience in the design, development, delivery, and operation of space-based remote sensing missions
OR Master's Degree and 12+ years of experience in the design, development, delivery, and operation of space-based remote sensing missions
OR PhD and 10+ years of experience in the design, development, delivery, and operation of space-based remote sensing missions
Expertise in the design and performance of EO/IR sensors
An active Secret U.S. Security Clearance. (A U.S. Security Clearance that has been active in the past 24 months is considered active).
Preferred Qualifications (Desired Skills/Experience):
20+ years of experience in the design, development, delivery, and operation of space-based OPIR missions
Subject Matter Expertise in earth-observing EO/IR missions
Experience leading multi-disciplinary technical teams
Experience with the missile warning, tracking, and defense mission across domains (air, ground, space, user, etc.)
Experience with modeling and simulation of constellation performance
Familiarity with mission modeling and simulation techniques to assess sensing mission performance
Possess active U.S. Top Secret/SCI Security Clearance
