Mechanical Engineer Intern

At Mantari Industries , we’re replacing yesterday’s public sector weather systems with a full stack, AI-native platform that senses, models, and predicts Earth’s atmosphere and oceans in near real time. Our mission is to sense Earth in its entirety — oceans, skies, and space — and close the gap between what nature does and what humanity knows. By building a distributed network of sensors fused with breakthrough AI, Mantari transforms raw environmental signals into actionable intelligence so that the world’s most critical outcomes, from global trade and securing grids to defending nations, are guided not by uncertainty, but by foresight.

Our autonomous edge sensing fleets, deep learning forecast models, and integrated customer decision engines will create the most precise weather intelligence on the planet—empowering industry, strengthening climate resilience, providing vital intelligence to American warfighters, and opening billion-dollar markets that don’t exist yet.

Backed by premier venture capital and led by engineers and scientists who’ve landed rockets and pioneered novel AI forecast techniques, we move fast, own the hard problems end to end, and measure success in real world impact. If you want to build frontier tech with outsized consequences, welcome aboard.

Summer internships will range between the months of May and August. All dates dependent upon the university schedule of the selected students. Internships are full-time and on-site in Los Angeles, CA.

The Mantari Mechanical Engineering Internship provides an opportunity to work on next-generation sensor hardware and integrated platform systems, contributing directly to products deployed in defense and weather applications. Interns will join a fast-paced team environment, collaborating on design, analysis, and test efforts for both prototype and production hardware.

As a lean, early-stage team, every contributor has a meaningful impact, and that includes our interns. You'll take on real ownership of projects, work directly alongside senior engineers, and see your contributions shape products that are actively being delivered to customers. Internships at Mantari are optimal for students looking to grow technically and professionally while working on high-impact projects in a startup environment.

We're dedicated to providing an experience that will let your decisions and contributions help drive Mantari's success.

• Cradle to grave the design and development of sensor hardware and mounting for field-deployable platforms
• Support test campaign planning and execution, including test fixture design and data analysis
• Create CAD models, detailed drawings, and perform basic engineering analysis (FEA, thermal, etc.)
• Lead design reviews and collaborate with multidisciplinary teams to meet hardware and integration requirements
• Perform hands‑on fabrication tasks or support prototyping and assembly operations when needed
• Support field test operations, including hardware setup, deployment, and on-site troubleshooting

• Junior or Senior academic standing
• Currently enrolled in a bachelor’s degree program in Engineering, Physics, or related technical field
• Strong understanding of core engineering concepts, with completed coursework in:
  • Statics
  • Dynamics
  • Mechanics of Materials
  • Deformable Bodies
• Experience using engineering tools such as CAD, MATLAB, and/or LabVIEW
• Strong written and verbal communication skills and ability to thrive in a team‑oriented environment

• Previous internship or co‑op experience in a technical role
• Experience with fabrication or machining (manual or CNC)
• Demonstrated success in technical extracurriculars (e.g., Rocket Club, Formula SAE, etc.)

Intern projects will be tailored to company needs and student skillsets closer to the start date. Example projects include:

• Sensor enclosure and housing design for ruggedized environments
• Mechanical integration of radar and weather sensor assemblies
• Test fixture development and environmental testing support
• Prototyping and fabrication support for hardware platforms
• Thermal and structural analysis for field-deployable sensor systems

Weather shapes every decision made on Earth. At Mantari you’ll write code that moves metal, launch sensors that tame storms, and see your work ship in weeks—not years. Join us to build the world’s first private full-stack weather platform and leave your fingerprints on infrastructure that will outlast us all.
Apply now—let’s create the future of weather, together.
