What We’re Looking For:

If you are an experienced systems engineer with a background in space systems architecture and design, and have at least 5 years of experience, you will be excited about the Systems Engineer III opening with Iridium on our SDA (Space Development Agency) Project. As a Systems Engineer III, you’ll independently deliver high-quality work and drive projects and deliverables to completion, including the development and execution of on-orbit test procedures and System Engineering artifacts that support SDA operations. You will provide critical operations and integration support to improve our efficiency and effectiveness by implementing processes, procedures, checklists, and software tools for ground and satellite operations. Working in this role, you’ll interface with the U.S. government in dealing with Iridium generated and delivered System Engineering documents that govern operations at the SDA operation centers. You’ll also focus on the design, development, and maintenance of functional on-orbit test procedures, working with multiple satellite vendors to ensure synergy of on-orbit tests, assist the SDA in the development of operational test procedures, and act as a liaison between the space contractors, ground contractors and government team during operations. You will work 12-hour shifts with a team onsite in a 24/7, multi-satellite operations environment. You will thrive in this role if you enjoy tackling complex challenges and working in a fast-paced, dynamic environment.

Be active in seeking out ways to continuously improve yourself and gain new knowledge

Skilled at the mechanics and operations of Low Earth Orbit Satellites

Things That Would be Great if You Brought to the Table:

An active/current Top-Secret Security Clearance or the ability to obtain a Top-Secret Security Clearance (A U.S. Security Clearance that has been active in the past 24 months is considered active)

Intelligence Community (IC) or Department of Defense (DoD) acquisition background

Experience with orbital mechanics, space vehicle launches and early orbit functions

Programming languages such as: Java, Java-Script, Python, Shell scripting

Familiarity with Atlassian Tool Suite such JIRA, R4J and Confluence

Working knowledge of Scaled Agile Framework (SAFe)

We’ll also need you to:
