About the position

We're looking to add a passionate Cybersecurity Detection and Response Analyst to our London 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 SOC team is involved in engineering (e.g., we built our own SOAR, email content scanning system, the entire alerting stack and much more) and we handle the incident response and remediation when a threat is found.

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.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.

Only hits

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

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. In this role, you’ll carefully consider the context of our decisions as we think about the tradeoffs 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.

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. 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 analysts.
