At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.
We are looking to add a Senior Electronics Test Engineer I to our team. If you are excited about working in a startup environment and are passionate about developing critical test systems for leading-edge satellite, spacecraft, and aerospace communication systems, we would like to hear from you.
In this position, you will be responsible for the design, analysis, and implementation of engineering test plans and procedures for board-level electronics products, including power, digital, and RF electronics. The ideal candidate possesses a strong combination of hardware and software knowledge with proficiencies in measurement techniques, test equipment, test architectures, automation, and integrated system testing. The successful candidate will work closely with multi-disciplinary teams to address company-wide test needs.
This role will be responsible for software products necessary throughout all phases of test and integration. Key projects will include developing and managing software for interfacing with flight hardware and test equipment in an abstract and flexible manner that can be quickly implemented into a variety of test campaigns, developing methods to store and access generated data, and equipping the test team with other software tools necessary to efficiently accomplish ambitious testing goals. Additionally, designing test solutions for flight hardware optimizing for reliability and efficiency, and developing modular, reusable test and automation software in Python (or similar languages) implemented in a variety of test applications to verify design and build quality.
A Senior Test Engineer I is distinguished by an ability to architect test systems, to draw insightful conclusions from test results, and to participate in “design for test” planning and review from the early stages of product development. The successful candidate will present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
