Senior Environmental Test Engineer

Wanna join the adventure? As a Senior Environmental Test Engineer at Loft Orbital, you will be responsible for the design, execution, and improvement of environmental testing that ensures the reliability and performance of Loft’s space hardware—from components and assemblies to full spacecraft. You will collaborate closely with design, manufacturing, and software teams to develop test plans, execute environmental and functional test procedures, then analyze the results to ensure our satellites and components meet mission requirements. This role offers the opportunity to expand your expertise with a variety of complex aerospace hardware and software, all while working in a fast-paced and collaborative environment. *Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions.  We strongly encourage you to apply, even if you don’t check all the boxes. Who We Are Loft: Space Made Simple. Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit. We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives. With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure. As an international company your resume will be reviewed by people across our offices so please attach a copy in English. About this Role: Support the design, development, and execution of environmental test plans, procedures, setups, and instrumentation for spacecraft and component-level testing. Execute and document environmental and functional tests, including vibration, thermal, thermal vacuum (TVAC), and electromagnetic interference (EMI). Collect, analyze, and interpret test data; generate reports and document results, flags, and non-conformances. Collaborate cross-functionally to ensure tests align with mission requirements, schedules, and quality standards. Contribute to process improvement initiatives for test documentation, configuration control, and data management. Must Haves: Bachelor’s degree in Electrical, Mechanical, Aerospace, or Systems Engineering, or equivalent experience. 7-10 years of experience in aerospace or related hardware testing. Familiarity with test methods and environmental test standards (e.g., GEVS, MIL-STD). Proficiency interpreting engineering drawings, schematics, and test specifications. Proficiency with data acquisition systems, instrumentation, and control systems. Experience with scripting or automation tools (e.g., Python, MATLAB, LabVIEW). A high degree of integrity and a strong sense of ownership. Strong problem-solving skills and attention to detail. Proficient working hands-on with hardware and in test lab environments. Nice to Haves: Exposure to requirements verification and validation processes. Experience supporting satellite or similarly complex aerospace environmental test campaigns. Familiarity with data management tools or configuration control systems. Willingness to support some off-hours or weekend testing when required.
