Top Tech Jobs & Startup Jobs in Los Angeles, CA

Develop and maintain real-time aircraft simulation environments for flight-control and avionics verification. Build SIL and HIL test systems, create MATLAB/Simulink models and generated code, integrate aircraft dynamics and hardware interfaces, improve simulation fidelity and performance, automate testing, and collaborate with GNC, avionics, embedded software, and systems teams to validate flight-critical systems.

Lead FP&A activities including budgeting, forecasting, variance analysis, scenario planning, and financial modeling. Partner with executives, technical teams, and functional leaders on board reporting, investor materials, program costs, capital expenditures, resource planning, and strategic decisions. Improve FP&A systems, reporting automation, multi-year planning, and profitability tracking in a hardware-focused defense aviation environment.

Supports supersonic aircraft development through structural static and dynamic analysis, external load definition, finite element modeling, aeroelastic and flutter evaluation, vibration environment definition, and validation using testing and flight data. Collaborates with aerodynamics and structures teams on aircraft programs. This is a 12-week summer internship for enrolled STEM students with strong engineering fundamentals, communication skills, and a minimum 3.0 GPA.

Support development of 6-DOF flight simulations and hardware-in-the-loop testing for flight software. Responsibilities include modeling vehicle dynamics, sensors, actuators, and engines; writing C++, Python, and MATLAB tooling; integrating avionics and flight hardware; troubleshooting with schematics and bench equipment; and automating logging, playback, and test workflows. The intern will independently own simulation and integration tasks within a multidisciplinary aerospace team.

Leads build reliability and quality engineering across aircraft design, manufacturing, testing, and flight operations. Responsibilities include quality planning, inspection methods, failure investigation, root cause corrective action, QMS requirements, containment, nonconformance and MRB resolution, lean process improvement, and inspector support. The role requires hands-on production-floor work, collaboration with design and manufacturing teams, and up to 25% travel.

Own and evolve internally developed business applications by documenting architectures, maintaining and enhancing production systems, reviewing AI-generated code, addressing technical debt, developing APIs and integrations, and establishing secure development, testing, CI/CD, deployment, monitoring, and support practices. Troubleshoot issues across application, infrastructure, integration, and data layers while partnering with IT, security, infrastructure, DevOps, and business stakeholders.

Installs, configures, monitors, troubleshoots, secures, and maintains local and wide area networks. Manages network hardware, wireless systems, VPNs, DNS, DHCP, IPAM, access controls, and intrusion detection. Develops documentation, supports infrastructure projects, resolves complex technical issues, participates in on-call incident response, and applies current networking technologies and NIST guidelines.

Build, automate, secure, and support enterprise IT, ICS, IoT, cloud, and on-premises infrastructure. Administer Microsoft 365, Entra ID, Intune, AWS, Azure, virtualization, networks, and cross-platform endpoints. Develop infrastructure-as-code and CI/CD workflows using PowerShell, Terraform, Ansible, GitLab, and C#. Resolve advanced escalations, improve uptime and security, maintain documentation, and collaborate with cybersecurity, software, and operations teams in regulated defense environments.

Supports aerospace vehicle integration, flight-test planning, system checkout, telemetry monitoring, troubleshooting, test-data analysis, and development of test hardware, tooling, wiring, instrumentation, and automation scripts. Collaborates with engineers, technicians, and pilots to prepare and execute safe, repeatable vehicle tests. The internship provides hands-on exposure to rapid hardware development and flight-test operations.

Mechanical Engineering Intern supporting structural design and integration of hydraulic, fuel, propulsion, avionics, and structural systems for supersonic aircraft. Responsibilities include hand calculations, FEA, structural and thermal analysis, subsystem trade studies, hardware development, fabrication, integration, testing, and technical presentations. The intern will collaborate with manufacturing, supply chain, test, suppliers, and customers.
