Software Engineer, Internship - Defense Tech

A World-Changing Company

Palantir builds the world's leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.

Software Engineers at Palantir build software at scale to transform how organizations around the world use data. As a Defense Tech Software Engineer Intern, you'll have an opportunity to grow more quickly than you ever envisioned, as you contribute high-quality code directly to Palantir's Gotham product. Palantir's defense product vertical builds mission-critical products for the modern warfighter, enabling them to securely integrate and visualize their data, perform rich analyses, and build sophisticated, full‑featured programs such as common operating pictures, alert‑triaging inboxes, and resource allocation planning tools driven by rich‑ML models.

Our customers use our defense offering to drive core operations within their organizations – these programs are relied upon for daily operations in the command centers and battlefronts of militaries across the world.

Palantir's Product Development organization is made up of small teams of Software Engineers, each focusing on a specific aspect of a product. For example, you might join a team that builds geospatial mapping tools for mission‑critical operations, or a component of the Gotham release infrastructure. We encourage communication and collaboration among teams to share context, skills, and experience, so you'll learn about many different aspects of each product.

As a Defense Tech Intern – you will be supporting work specifically focusing on delivering our Palantir Defense capabilities to our most critical mission partners. You'll be involved throughout the product lifecycle – from idea generation, design, and prototyping to execution and shipping. You'll be paired with a mentor dedicated to your growth and success. You'll collaborate closely with technical and non‑technical counterparts to understand our customers' problems and build products that tackle them.

• Ownership:
  We see projects through from beginning to end in spite of obstacles we may encounter.
• Collaboration:
  
  We work internally with people from a variety of backgrounds – such as other Software Engineers, Product Managers, Designers and Product Reliability Engineers. We also partner with our business development teams (Forward Deployed Engineers, Deployment Strategists) in order to understand and solve our customers' problems.
• Trust:
  We trust each other to effectively handle time and priorities, and don't micromanage. We want people to have the space to think for themselves, while feeling supported by their team.

It doesn't matter what languages you know when you join us, but it does matter that you can write clean, effective code and learn new languages quickly. Our software is constantly evolving, so we need engineers who can do the same. Alongside peers that bring diverse experience – whether you're a former university TA, switched to CS recently, or are a hackathon enthusiast – you'll build your skills to apply the best technology to solve a given problem.

Right now, we use:

• Varying languages, including Java and Go for backend and Typescript for frontend
• Open-source technologies like Cassandra, Spark, Elasticsearch, React, and Redux
• Industry‑standard build tooling, including Gradle and Git Hub

• Ability to communicate and collaborate with a variety of individuals, including engineers, users and non‑technical team members.
• Willingness to learn and make decisions independently, and the ability to ask questions when needed.

• Engineering background in fields such as Computer Science, Mathematics, Software Engineering, and Physics.
• Familiarity with data structures, storage systems, cloud infrastructure, front‑end frameworks, and other technical tools.
• Active US Security clearance, or eligibility and willingness to obtain a US Security clearance prior to start of internship.
• Experience coding in programming…
