About the position
Company context from the listing:
We're looking to add a passionate Cybersecurity Detection and Response Analyst to our Hong Kong office to help protect Jane Street’s employees, data and infrastructure from the wilds of the internet.
This is not (just) an eyes-on-glass, click ops role—our cybersecurity analysts are also responsible for developing the tools and systems we use to guard the firm. Think about this role as some combination of incident responder, detection engineer, security engineer, SOC automation engineer, threat hunter, threat modeler and security awareness engineer.
Our analysts research and prioritise what threats need to be monitored, hunt for them in our data, write code to detect them and constantly tune the detection to prioritise quality over quantity. We maintain full control over the alerts we respond to, and own all stages of the detection and response lifecycle.
Our Cybersecurity team is a skilled group of programmers and security experts who are dedicated to keeping the firm safe. We consider ourselves to be tapped into developments in the broader cybersecurity space, and can tell the difference between the latest cool hack by security researchers and what actually matters in our day-to-day.
You will also act as an ambassador of best practices to the rest of the firm. Team members understand and practice good personal cybersecurity hygiene, and are able to talk to others about it.
About you
Company context from the listing:
- Have (or will have) a degree in computer science, engineering, information systems or a related field
- An avid follower of cybersecurity news
- A strong programmer who can demonstrate high potential and an aptitude for learning
- Comfortable and interested in managing your code and configs in version control, and with using your editor (we don't care which though)
- Familiar with threat modelling; able to understand how cybersecurity fits into the firm’s broader goals and clearly communicate security tradeoffs to our colleagues
- Able to explain the cybersecurity decisions you’ve made in your own life, and how you’ve approached thinking about those decisions
- Able to adapt to changing scenarios and make challenging decisions under pressure
- Humble about what you know and don’t know; not afraid to ask questions and admit mistakes
- An intellectually curious problem solver with a positive, collaborative attitude
- Fluent in English

Build a standout application
For the Cybersecurity Analyst 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.
