About the Position
Company context from the listing:
Our goal is to give you a real sense of what it's like to work at Jane Street full time while also providing a truly unparalleled educational experience. 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.
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 the automation tools and 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.
On any given day, you may be brainstorming approaches to improve systems and workflows, writing code, or learning about a 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.
After your initial training, you'll work in tandem with full-timers on projects drawn directly from our team's mission-critical stack. While your projects may vary in scope and content, they could include things like::
- Developing and maintaining tools and applications related to Windows automation and configuration management
- Improving our CI/CD systems, cross-platform frameworks, and software development environments
- Improving the efficiency and scalability of our tools, services, and monitoring solutions
- Implementing editor and workflow improvements to streamline coding and deployment workflows across IT

Build a standout application
For the Windows Engineer at Jane Street, reviewers look for concise evidence over buzzwords. Mirror the language of the posting sparingly, quantify support or delivery outcomes, and show how you handled ambiguity, time-zone collaboration and user empathy. Keep your resume to impact, keep your cover note to one page, and link to artifacts — tickets resolved, docs shipped, dashboards owned — that prove you can operate in a fast-moving Web3 team. Prepare to discuss a time you turned a confusing user report into a clear fix and how you measure quality in support and operations.
Web3 hiring values reliability: on-time follow-through, clear writing, and a track record of improving runbooks and tooling. Treat the application as a work sample. For interviews, be ready to walk through how you prioritize across time zones, handle a difficult user, and decide when to escalate versus resolve directly. Show how you document decisions so the next teammate benefits.
In a distributed Web3 org, trust builds through written clarity. Use the cover note to demonstrate it. Add links to public work, keep formatting scannable, and close with a clear ask. Hiring managers skim — make impact obvious in the first half-page.
Career growth in Web3 rewards continuous learning. Follow protocol changelogs, practice with testnets, and contribute to open issues. Small, consistent contributions compound into credibility more than one-off credentials.
