Software Engineer Internship in New York, NY

Palantir builds software for data-driven decisions and operations, bringing the right data to the people who need it. Its platforms help partners develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.

The Role

The team applies open-source data technologies to some of the world's hardest problems. It builds the data processing infrastructure behind Palantir Foundry, supporting hospitals, clinical teams, and the movement of essential supplies during global disruption.

You will work inside the systems that power this work, including how computations are represented, how query plans are optimized, how operators execute, and how data is read and written efficiently. The team builds on and extends Apache Spark, Apache DataFusion, and Apache Iceberg. Its work serves many Foundry products and workloads, including no-code pipelines, interactive analysis, and the processing that keeps the Ontology up to date.

Working alongside experienced engineers, you will take on real problems in production systems, such as writing a new planning rule, adding a capability to a native execution engine, or making large tables faster to scan. You will see your work through design, code review, testing, and release. Correctness, compatibility, and predictable performance are central, and you will learn how to deliver all three.

Technologies We Use

• Java, Scala, Rust, and Python
• Apache Spark, Apache DataFusion, Apache Comet, and Velox for data processing and query execution
• Apache Iceberg for table management and catalog interoperability
• Apache Arrow and Apache Parquet for in-memory data processing and columnar storage
• Gradle and Cargo for builds, and GitHub for collaboration

No prior experience with these technologies is needed. You are expected to learn them on the job.

What We Value

• Curiosity about how data systems work, from query optimizers and execution operators to file formats and distributed processing
• A high bar for correctness and a willingness to dig until you understand why something behaves the way it does
• Comfort following a problem across languages, services, and layers of the stack
• A practical approach to performance, grounded in measurement rather than intuition
• Eagerness to learn, ask questions, and incorporate feedback
• Interest in applying deep systems engineering to real-world problems, with empathy for the people who depend on the software

What We Require

• Currently pursuing or recently completed a Bachelor's, Master's, or PhD in Computer Science, Mathematics, Software Engineering, Physics, or a similar field, or equivalent practical experience
• Proficiency in at least one language such as Java, Rust, Scala, C++, or C
• Strong foundations in algorithms, data structures, and concurrency
• Strong written and verbal communication skills
• Coursework or projects in databases, compilers, operating systems, or distributed systems
• Contributions to open-source projects
• Must be planning on graduating in 2028, with this as the final internship before graduating

Compensation and Benefits

The estimated pay for this position is $10,500 per month. Total compensation is determined by each candidate's qualifications, experience, skills, and other factors. This estimate excludes benefits and any long-term incentives.
