About the role

Autonomy Engineer (Mid Career) - Millennium Space Systems

Company:

Millennium Space Systems

Millennium 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.

Job Summary

Autonomy Engineering is focused on enabling mission success through comprehensive on-board fault management and autonomy. Engineers in the group are integral throughout the entire program lifecycle. They define the underlying architecture for fault detection, isolation, and response (FDIR), and own the development and validation of satellite/constellation specific fault configuration(s). They are the chief architects and implementers of satellite/constellation autonomy, ensuring mission level objectives are met and spacecraft health and safety are always maintained. They are key stakeholders in the design and validation of mission CONOPS and Design Reference Missions (DRM), and participate in comprehensive end-to-end software integration, validation, and testing.

As a Lead/Senior Autonomy Engineer you will be the Autonomy responsible engineering authority (REA) for a program, study, or proposal. You will develop and decompose fault & autonomy requirements; define states, modes, and transitions; lead development of the fault & autonomy architecture for satellites/constellations, including fault-tolerance and redundancy requirements; define and analyze thresholds and persistence of on-board fault tests; design and test fault responses to ensure containment of failed hardware and health and safety of on-orbit satellites; provide tools and procedures for use during on-orbit mission operations; and support on-console mission operations for on-orbit spacecraft as a mission specialist. You may lead a multidisciplinary team of engineers, decomposing/prioritizing work and verifying results. 

This position's internal job code is Systems Engineer. Our team is currently hiring for Level 3-4.

Position Responsibilities:

  • Lead fault and autonomy requirements definition, verification, and validation

  • Define satellite/constellation states, modes, transitions, and other autonomous spacecraft behaviors

  • Contribute to - and in some cases own - architecture concepts, CONOPS, and technology trade-off analyses

  • Design and validate onboard fault detection, isolation, and responses and perform end-to-end validation of autonomy products and behaviors

  • Support on-console operations for on-orbit missions

  • Other duties as assigned

This position is expected to be 100% onsite. The selected candidate will be required to work onsite at one of the listed location options. 

Security Clearance and Export Control Requirements

This position must meet Export Control compliance requirements, therefore a “US Person” as defined by 22 C.F.R. § 120.15 is required. “US Person” includes US Citizen, lawful permanent resident, refugee, or asylee.

Basic Qualifications (Required Skills/Experience):

  • Bachelors degree in engineering or a related field and 5+ years experience in satellite design and/or operation. Advanced degrees may augment years of industry experience.

  • Familiarity with one or more satellite subsystems and/or system-level analysis

  • Experience in the design, development, and verification of spacecraft fault detection, isolation, and response (FDIR)

  • Experience in the design, development, and verification of spacecraft autonomy software/configuration

  • Familiarity with satellite testing and/or on-orbit mission operations

  • This position requires the ability to obtain a U.S. Security Clearance for which the U.S. Government requires U.S. Citizenship. 

Preferred Qualifications (Desired Skills/Experience):

  • 9+ years experience in satellite design and/or operation

  • Expertise with one or more satellite subsystems and/or system-level analysis

  • Experience designing satellite mission CONOPS, and deriving fault/autonomy requirements from those CONOPS

  • Technical leadership experience with the ability to set direction of program work and create processes and standards to
