Top Tech Jobs & Startup Jobs in Los Angeles, CA

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.

Support development of lithium-ion battery packs for spacecraft through electrical and structural analysis, battery test hardware development, qualification testing, PCB bring-up, battery assembly, CAD modeling, and collaboration with electrical, mechanical, manufacturing, and test teams. This is a 12-week, on-site internship in Redondo Beach, California, with exposure to the full spacecraft development lifecycle.

Develop full-stack software enabling spacecraft command, telemetry, and control. Build web applications, APIs, automation tools, telemetry-processing systems, dashboards, and backend services supporting mission operations and ground testing. Write reliable, tested, maintainable code and collaborate with flight software, GNC, and mission operators. This is a 12-week, on-site internship in Redondo Beach, California, with possible overtime.

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.

Propulsion Engineering Intern will support spacecraft propulsion component and system development. Responsibilities include owning development tasks, collaborating with design, testing, and manufacturing teams, validating hardware performance, resolving technical issues, and producing hardware, analyses, and documentation. The 12-week, on-site internship requires hands-on experience with fluid or mechanical systems and foundational knowledge of fluids, thermodynamics, heat transfer, mechanics, and materials. Familiarity with MATLAB, Python, or Excel is preferred.
