Job Summary

Autonomy Engineering is focused on design, analysis, and development of mission Concepts of Operations (CONOPS) from customer use cases and requirements, and enabling mission success through comprehensive on-board fault management and autonomy. Engineers in the group are integral throughout the entire program lifecycle. 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.

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.

As an Autonomy Engineer on the Autonomy Team, you will be the Responsible Engineering Authority (REA) for all Autonomy for a program, study, or proposal. You will define fault & autonomy requirements; define states, modes, and transitions; define and develop 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 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. In addition to execution of technical design, analysis, and operation, you may be responsible for project management activities to support programs, ensuring that high-quality work products are delivered on-time.

This position's internal job code is Systems Engineer. Our team is currently hiring for Levels 2-3.
