We're looking to add a passionate Cybersecurity Engineer to our Hong Kong or Singapore office to help protect Jane Street’s employees, data and infrastructure from the wilds of the internet. Our Cybersecurity Engineers are responsible for developing and using monitoring tools to guard the firm, as well as handling incident response and remediation when a threat is found.
Our team considers itself to be tapped into the developments happening within the broader cybersecurity space, and able to tell the difference between the latest cool hack by security researchers and what actually matters in our day-to-day. In this role, you’ll carefully consider the context of our decisions as we think about the trade-offs we’re making in our approach to resolving cybersecurity issues.
We’ll expect you to apply a methodical approach to performing unstructured investigations to locate and repair the source of a security issue. While there will be an element of operational coverage, your time will also be spent on projects to improve our detection capabilities, automation and efficiencies, as well as performing threat hunts, allowing you to grow your skill set and impact.
You will also act as an ambassador of best practices to the rest of the firm. All of our team members understand and practise good personal cybersecurity hygiene, and are able to talk to others about it. A key component of doing well in this position is bringing everyone else along with you on the cybersecurity journey, and you should be excited to learn from your colleagues and pass that learning on to new engineers.
If you're a recruiting agency and want to partner with us, please reach out to [email protected].
Trades stocks, bonds and funds as a market maker
Jane Street trades stocks, bonds, options, and exchange-traded funds with its own money as a market maker, a firm that constantly quotes prices to buy and sell so other investors can trade whenever they want. In 2025, it made more money from trading than JPMorgan Chase or Goldman Sachs, the biggest trading banks on Wall Street. Its traders, researchers, and engineers build computer-driven strategies that trade on exchanges and other venues around the world, and it also trades directly with large institutional clients. It earns the small gap between buying and selling prices across huge volumes, plus gains on positions it holds for minutes to days. Jane Street was founded in 2000 and is based in New York.
