Software Engineer Intern Jobs in El Segundo, CA (NOW HIRING)

Long Beach, California, United States

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 Software Engineering Internship provides an opportunity to work on the software systems that power next-generation sensor platforms and AI-driven weather intelligence, contributing directly to products deployed in defense and weather applications. Interns will join a fast-paced team environment, collaborating on software development, data pipelines, and deployment efforts across both cloud and edge computing environments.

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.

• Contribute to the development of software for sensor data ingestion, processing, and visualization across Mantari's platform
• Support the design and implementation of APIs, microservices, and data pipelines for weather and radar applications
• Write clean, tested code and participate in code reviews to maintain high engineering standards
• Participate in design reviews and collaborate with multidisciplinary teams to meet system and integration requirements
• Support deployment and DevOps workflows, including CI/CD pipelines and cloud infrastructure
• Support field test operations, including software configuration, data collection, and remote debugging

• Junior or Senior academic standing
• Currently enrolled in a bachelor's degree program in Computer Science, Software Engineering, or related technical field
• Strong understanding of core software concepts, with completed coursework in:
• Data Structures and Algorithms
• Operating Systems
• Databases or Systems Programming
• Proficiency in at least one programming language (e.g., Python, C/C++, or Rust)
• Experience with version control (Git) and collaborative development workflows
• 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 cloud platforms (AWS, GCP, or Azure)
• Familiarity with containerization (Docker), CI/CD pipelines, or infrastructure-as-code
• Exposure to real-time data systems, embedded software, or ML/AI frameworks
• Demonstrated success in technical extracurriculars (e.g., student project teams, hackathons, open-source contributions, personal projects, etc.)

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

• Build or extend data pipelines for ingesting and processing real-time sensor and radar data
• Develop internal tools or dashboards for visualizing weather and environmental datasets
• Contribute to edge computing software for deployed sensor platforms
• Build and improve automated testing and CI/CD infrastructure
• Develop API integrations connecting Mantari's platform to customer-facing applications

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.
