Development Test Engineering Intern supporting spacecraft and rocket propulsion testing. Responsibilities include designing and building fluid, mechanical, and electrical test systems; setting up and inspecting hardware; troubleshooting equipment; and conducting test operations. The role collaborates with propulsion, avionics, vehicle, integration, and manufacturing teams. Hands-on experience with fluid or mechanical systems is required, while experience with pneumatic, hydraulic, electromechanical, optomechanical, or propulsion test equipment is preferred.

Plans, builds, executes, and analyzes tests for in-space mobility hardware. Designs test fixtures for fluid, cryogenic, high-pressure, environmental, mechanical, and structural testing; operates test stands, troubleshoots live events, documents results, and collaborates with design, manufacturing, analysis, and operations teams to mature early-stage designs into flight-ready hardware.

Supports electromagnetic compatibility engineering for spacecraft components and systems. Responsibilities include optimizing EMC automation, bringing up semi-anechoic chambers, conducting EMC analysis, simulation, and testing, troubleshooting electromagnetic performance, preparing test plans and reports, and operating RF laboratory equipment. The intern collaborates with RF, avionics, mechanical, and software engineering teams and works on-site in Redondo Beach, California for a 12-week summer internship.

Drafts, reviews, and negotiates commercial, launch, vendor, supplier, lease, confidentiality, and other business agreements. Advises stakeholders on contract interpretation, performance issues, amendments, disputes, renewals, and terminations. Maintains templates, playbooks, and contract tracking processes while identifying legal and commercial risks and escalating complex matters. Collaborates with business development, finance, mission management, and external counterparties in a fast-paced aerospace environment.

Develop embedded software for custom avionics hardware supporting ground testing, manufacturing, and spacecraft flight functions. Responsibilities include implementing processor, peripheral, communication, and closed-loop control functions; writing test and development code for avionics, fluids, and propulsion systems; and producing rigorous, reviewed, tested flight and manufacturing software. The intern will collaborate with hardware, propulsion, and GNC engineers while working onsite in Redondo Beach.

Support spacecraft vehicle engineering projects involving primary structures, tanks, mechanisms, thermal systems, hardware design, analysis, manufacturing, and testing. Collaborate with design and manufacturing engineers to build and test spacecraft hardware, resolve technical issues, and contribute to clean-sheet spacecraft development. This is a 12-week, on-site internship in Redondo Beach, California.

Supports security monitoring, alert triage, vulnerability management, access reviews, endpoint and network control validation, policy compliance, documentation, security awareness, governance and risk assessments, and audit readiness. The intern works under supervision in a regulated aerospace and defense environment and contributes to NIST 800-171 and CMMC compliance activities.

Supports the mechanical design and development of precision optical hardware for spacecraft, including lens barrels, telescope structures, mounts, baffles, flexures, gimbals, and pointing mechanisms. Converts optical requirements into manufacturable, alignable designs and creates CAD models, drawings, tolerance analyses, GD&T, BOMs, interface documents, assembly procedures, and test fixtures. Collaborates with optical engineers through design, build, testing, and flight qualification.

Design, manufacture, and test custom RF systems for spacecraft. Responsibilities include selecting RF components, running simulations and link budgets, creating validation plans, developing RF schematics and layouts, supporting manufacturing, and conducting bench testing and system bring-up. The intern will collaborate with RF, avionics, software, and mechanical engineers and use CST, HFSS, and ADS for RF front-end design.

Supports spacecraft and liquid rocket propulsion assembly, integration, and testing. Responsibilities include designing test systems, inspecting and troubleshooting hardware, conducting test operations, creating documentation, developing tooling and fixturing, improving production processes, and resolving technical issues. The intern collaborates across engineering teams and performs hands-on work with mechanical, fluid, electrical, pneumatic, hydraulic, and electromechanical systems.
