We welcome applicants across a range of experience levels to apply. ## Description Integration & Test * Lead and own integration and test campaigns at every level of spacecraft development - component, box, subsystem, and full vehicle * Define the test philosophy for the bus: what gets acceptance tested, what gets protoqualified, what qualifies by similarity, and how that philosophy holds up as we move from a one-off development unit to rate production * Develop acceptance, qualification, and R&D test plans for spacecraft systems, and drive them through execution and closure * Work with systems and subsystems leads to defining requirements and the verification and validation plans that close them * Develop, maintain, and operate environmental test systems - random vibration, TVAC, thermal cycling, EMI/EMC, mass properties * Design, build, and maintain mechanical and electrical ground support equipment (MGSE/EGSE) and the facilities that house it * Interface with ground test software, implement flight software configuration changes for test, and work hands-on with hardware-in-the-loop test systems * Own test data: what we record, how it's reviewed, what constitutes a pass, and how results get back to the responsible engineer Assembly & Manufacturing * Partner with Design Engineering to drive Design for Manufacture and Design for Test into the bus while the design is still moving - access, fastener reach, connector orientation, test point availability, handling and lift points * Design, procure, install, and validate assembly, test, and verification processes, including the tooling, fixtures, and work instructions behind them * Support development builds to surface early learnings and retire integration risk ahead of production ramp * Triage and diagnose failures, run deep technical investigations, and determine the path forward - containment, risk mitigation, and root cause resolution * Drive process improvements across manufacturing, test, and integration, with an explicit eye toward repeatability across many identical vehicles * Contribute to change management, assessing the risk and impact of design or process changes on build and test * Plan and specify the integration facility footprint as the program scales - clean room, integration bay, test cell, and the flow between them ## Related Videos - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [TresJS a new declarative ThreeJS as Vue components](https://www.wearedevelopers.com/videos/543-tresjs-a-new-declarative-threejs-as-vue-components) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Code to Road in < 12 hours](https://www.wearedevelopers.com/videos/1082-code-to-road-in-12-hours) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Stop Guessing, Start Measuring: Evaluating RAG Systems with Synthetic Test Data](https://www.wearedevelopers.com/videos/1982-stop-guessing-start-measuring-evaluating-rag-systems-with-synthetic-test-data) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Why Attend a Developer Event in 2026?](https://www.wearedevelopers.com/magazine/688-why-attend-a-developer-event-in-2026)
