Top Tech Jobs & Startup Jobs

Designs and conducts mechanical and environmental tests, operates specialized test equipment, performs instrumentation and data acquisition, analyzes results, and prepares technical reports. The role supports vibration, shock, modal analysis, structural, thermal, fluidic, and diagnostic testing. Responsibilities also include engineering calculations, safety documentation, design reviews, project planning, and collaboration with internal and external organizations. Higher-level assignments provide technical oversight, strategy, project leadership, and committee participation.

Conduct mechanical and environmental testing, including vibration, shock, modal analysis, load testing, instrumentation, and data acquisition. Operate specialized test equipment, analyze results using MATLAB, prepare engineering and safety documentation, perform structural and thermal calculations, and support design, fabrication, assembly, and engineering reviews. Higher-level assignments independently define requirements and manage project plans, schedules, budgets, and technical activities.

Lead telecommunications infrastructure projects involving outside and inside plant systems, fiber and copper cabling, wireless infrastructure, networking, and telecommunications equipment. Manage the migration to a modern telecommunications facility, coordinate vendors, contractors, technicians, designers, and stakeholders, establish priorities, report project status, resolve technical and operational issues, mitigate risks, and provide technical direction to field teams.

Develop and lead precision target fabrication projects for the National Ignition Facility, from concept and design through fabrication, assembly, metrology, qualification, and delivery. Responsibilities include requirements development, engineering analysis, prototyping, manufacturability assessments, technical documentation, production support, risk tracking, and coordination with scientists, engineers, vendors, and manufacturing teams. The role requires full-time onsite work and may include technical leadership at the higher level.

Develop and maintain complex software systems for LLNL’s security program.
