Instrument System/Test Engineer II, Steward Observatory

The University of Arizona's Steward Observatory invites you to apply to the role of Instrument System/Test Engineer II. As an Instrument System/Test Engineer II, you will support the development, integration, and testing of advanced instrumentation for both groundbased and spacebased telescope programs, including a highvisibility, privately funded space mission led by Steward Observatory. This role works closely with mechanical, electrical, optical, and software engineers to deliver complex, highprecision optomechanical and spaceflightqualified systems.

The successful candidate will have handson experience building, assembling, and validating hardware, along with a working knowledge across electrical, optical, mechanical, and software domains. This broad technical base is essential for supporting the development and integration of delicate spacegrade instrumentation and contributing to subsystemlevel performance and reliability.

Key responsibilities include supporting integration and test (I&T) activities, contributing to subsystem design baselines, executing test procedures, and generating technical documentation required for configuration control and mission assurance. In this role, you will participate in design reviews, test readiness activities, and engineering working groups, ensuring that integration and testing requirements are clearly defined, implemented, and validated.

Strong communication and teamwork skills are required, as you will represent the engineering team in internal and occasional external technical exchanges. This position also provides an opportunity for you to contribute to cuttingedge astronomical instrumentation and spacemission development while gaining experience in multidisciplinary system engineering practices.

Outstanding U of A benefits include health, dental, and vision insurance plans; life insurance and disability programs; paid vacation, sick leave, and holidays; U of A/ASU/NAU tuition reduction for the employee and qualified family members; retirement plans; access to U of A recreation and cultural activities; and more!
