Software Engineer, Internship - Query Engines

 

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.

We are a software engineering team applying open-source data technologies to some of the world's hardest and most important problems. We build the data processing infrastructure that underpins Palantir Foundry, supporting applications that help hospitals care for more patients, help clinical teams coordinate timely diagnoses, and keep essential supplies moving through global disruption.

 

You will work deep inside the systems that make this possible: how computations are represented, how query plans are optimized, how operators execute, and how data is read and written efficiently. We build on and extend Apache Spark, Apache DataFusion, and Apache Iceberg, bringing advances in open-source engines and table formats into the demanding environments our customers operate in. Our work serves many products and workloads across Foundry, 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 our production systems. That could mean 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 to everything we build, and you will learn how to deliver all three.

 

Join us if you want to learn how modern data systems work from the inside and apply that knowledge to consequential problems.

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

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 our software

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. This should be your final internship before graduating.

The estimated salary range for this position is estimated to be $10,500/month.

In keeping consistent with Palantir’s values and culture, we believe employees are “better together” and in-person work affords the opportunity for more creative outcomes. Therefore, we encourage employees to work from our offices to foster connectivity and innovation. Many teams do offer hybrid options (WFH a day or two a week), allowing our employees to strike the right trade-off for their personal productivity. Based on business need, there are a few roles that allow for “Remote” work on an exceptional basis. If you are applying for one of these roles, you must work from the state in which you are employed. If the posting is specified as Onsite, you are required to work from an office.

 

If you want to empower the world's most important institutions, you belong here. Palantir values excellence regardless of background. We are proud to be an Equal Opportunity Employer for all, including but not limited to Veterans and those with disabilities. Palantir is committed to making the application and hiring process accessible to everyone and will provide a reasonable accommodation for those living with a disability. If you need an accommodation for the application or hiring process, please reach out and let us know how we can help.
