Learn more about Jane Street’s internship program here.

About the Position

If you are imagining a daily routine that involves making copies and watching as someone turns a computer off and back on, think again: this is not your typical IT internship.

Our internships provide a great introduction to Jane Street and how we think about and solve problems across all teams. Often, successful interns have been invited to return for a full-time position after graduation.

About You

We don’t expect you to have a background in finance or any other specific field—we’re more interested in how you think and learn than what you currently know. You should be:

• Graduating in 2027 or 2028
• Available to work 40 hours per week in person in our Hong Kong office (approx. hours are 8:30 a.m. to 5:30 p.m. Monday - Friday)

• Able to deconstruct technical problems, and willing to take a hands-on approach to gain experience in diagnosing, troubleshooting and resolving technical issues at the desktop, server and network levels
• Able to develop and maintain technical documentation
• Interested in learning (if not already experienced with) a scripting language, such as PowerShell or Bash
• Fluent in English

More recently, Python has become a vital part of Jane Street’s research and trading work, acting as the go-to language for data analysis, visualization, and machine learning. 

Beyond our own environment, we also recognize the value of open source software, leveraging it in our daily work and releasing over a million lines of our own code as open source. We’re also always looking for ways to expand open source projects, and provide ongoing support to things like Mercurial, the OCaml compiler, and the OPAM package manager. That said, we’re interested in talented engineers with experience in any language—most of us came in with little to no practical experience in OCaml before we joined.

The Role

We’re looking for a QA Engineer who loves games, sweats the details, and enjoys learning new technology. Motion-based QA is different from traditional game QA: you’ll test with your whole body in real-world environments (lighting, room sizes, player heights, 1–4 players, etc.). Prior motion-gaming experience is not required—strong QA fundamentals and a learning mindset are.

What You'll Do

• Create and execute test plans and test cases for motion-based games and the Nex Playground experience.
• Validate core player experience for living-room play: onboarding, clarity, responsiveness, and “is this fun and understandable?”
• Test motion-game fundamentals such as responsiveness/latency, recognition consistency, occlusion handling, and edge cases.
• Perform functional, usability, regression, localization, and device/compatibility testing across the product surface area.
• Write excellent bug reports with clear repro steps, expected vs. actual results, environment details, and short video captures when helpful.
• Collaborate cross-functionally: clarify requirements, ask good questions, and flag risk areas early.

What We're Looking For

• 1–2 years of experience in IT or the game industry (or equivalent hands-on experience).
• Strong understanding of QA methodologies, tools, and processes.
• Excellent analytical and problem-solving skills.
• Strong attention to detail and a commitment to quality.
• Good communication and teamwork skills.
• Ability to work independently and manage multiple tasks simultaneously.
• Good command of written and spoken English.
• Hands-on comfort with hardware and TV setups, including basic troubleshooting (network, setup flows, updates)
• Willingness to perform physical movements during testing and appear in internal test recordings.
• A genuine interest in games and player experience—especially party/family-friendly titles.

Nice to Have

• Cantonese and/or Mandarin fluency
• Experience testing camera-based, motion, AR, or computer vision products.
• Experience testing multiplayer/local co-op or party games.
• Familiarity with Unity, Android-based hardware, or mobile gaming.
• Experience setting up consumer electronics (TVs, consoles, streaming devices).
• Experience with test automation or scripting (even small personal projects).
