Windows Engineer - 2024 Summer Internship

About the Program

Our goal is to give you a real sense of what it’s like to work at Jane Street full time. Over the course of your internship, you will explore ways to approach and solve exciting problems within your field of interest through fun and challenging classes, interactive sessions, and group discussions—and then you will have the chance to put those lessons to practical use.

As an intern, you are paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done. When you’re not working on your project, you will have plenty of time to use our office amenities, physical and virtual educational resources, attend guest speakers and social events, and engage with the parts of our work that excite you the most.

If you’ve never thought about a career in finance, you’re in good company. Many of us were in the same position before working here. If you have a curious mind, a collaborative spirit, and a passion for solving interesting problems, we have a feeling you’ll fit right in.

About the Position

As a Windows Engineering intern, you’ll work side by side with full-timers in the IT department to learn how we design, deploy, secure, and maintain key infrastructure components that are critical to Jane Street's success. Our Windows Engineers manage a combination of systems we’ve created ourselves, open-source tools meshed together to provide higher-level functions, and integrations with industry-leading third-party tools and platforms. All of these systems serve to support the Windows desktop and server estate, as well as the tech infrastructure across the company, regardless of platform.

On any given day, you may be troubleshooting technical issues, brainstorming approaches to improve systems and workflows, writing code, or learning about new technology our team may want to deploy. You’ll also learn how we use OCaml (our primary development language), F# (a similar language used with our Windows systems), and PowerShell (a scripting language used for the majority of our automation in IT) in our day-to-day work, and gain exposure to the libraries and tools that are foundational to our internal systems.

During the internship, you’ll be exposed to technologies ranging from directory services, DNS implementations, and software deployment tools, to enterprise telephony infrastructure, remoting protocols, and hardware/virtualization platforms.

After your initial training, you’ll work in tandem with full-timers on two projects. You’ll also have an opportunity to work on some more general engineering tasks. While your projects may vary in scope and content, they are drawn directly from our team’s mission-critical stack and could include things like:

  • Developing and maintaining tools and applications related to user and group administration, hardware/software inventory, operating system builds, and software development environments
  • Identifying, researching, and remediating tech vulnerabilities and improving related tooling
  • Automating repetitive tasks ranging from user onboarding to performing security assessments on new software
  • Standardizing our Windows, telephony, and virtualization environments by optimizing code and monitoring tools (infrastructure as code)
  • Performing wide-scale configuration changes

About You

We don’t expect you to have a background in one specific field. We’re more interested in how you think and learn than what you currently know. We’re looking for smart people who enjoy solving problems and are:

  • A strong programmer who can demonstrate high potential and an aptitude for learning
  • Knowledgeable of operating system fundamentals and computer architecture
  • Able to understand network protocols at a basic level
  • Intellectually curious, collaborative, and eager to learn
  • Humble, unafraid to ask questions, and is able to admit their mistakes
  • A strong communicator
  • As comfortable at the command line as you are in a GUI 
  • Experience with Windows Operating systems—whether that’s from coursework, time spent as a systems administrator for your campus computer lab, side projects, or something else
  • Fluency in English required


Base salary is $250,000.
