We are looking for an enthusiastic, motivated, and technically curious individual—with an IT operations focus—to join Jane Street’s IT Security team, and contribute to securing our firm's IT computing platforms and identities. This will involve technical hands-on work, creative problem-solving, and collaboration across teams.
Additional responsibilities of this role will include:
- Deploying, documenting, and implementing security controls at scale
- Acting as a key component to our Vulnerability Management program to ensure we’re detecting and mitigating vulnerabilities
- Providing guidance and support to the broader IT department and IT Operations team as security incidents arise
- Developing both technical and non-technical solutions in collaboration with engineering teams to address security concerns
- Contributing to the development of our team’s operational playbooks and procedures
We’re looking for someone who loves collaborating alongside others, enjoys triaging complex problems, and is able to delegate and escalate tasks effectively. This role is anything but siloed—you will be a key communicator, translating complex technical issues for various audiences while maintaining a high level of technical accuracy.
While we’re open to individuals from a range of backgrounds, someone who’s worked in a code-driven or declarative environment and has hands-on experience with security incident response is preferred.
About You- Have 5-7 years of experience as a security or operations engineer, with a technical background rooted in Windows
- Can maintain, support, and administer Windows, macOS, and hybrid identity platforms
- Have demonstrated knowledge of typical attack patterns, adversary methods, and protective technologies utilized to mitigate related risks
- Strong troubleshooter and debugger; familiar with trending and log analysis, and have hands-on experience using system performance tools to identify production disruptions
- Can deploy and implement Endpoint Security controls in highly available environments (e.g., application control, log aggregation, host-based firewalls, EDR, disk encryption)
- Can use PowerShell scripting to automate security tasks and to analyze data at an intermediate level
- Excellent written and verbal communicator
- Able to navigate ambiguity and changing priorities with confidence
- Collaborative and approachable; eager to be a team player
- Having knowledge of macOS security fundamentals is a plus

Jane Street Insights
What We Do
Jane Street works differently. As a liquidity provider and market maker, we trade on more than 200 trading venues across 45 countries and help form the backbone of global markets. Our approach is rooted in technology and rigorous quantitative analysis, but our success is driven by our people. Our bright, beautiful offices in the heart of New York, London, Hong Kong, and Amsterdam are open and buzzing with conversation. We come from many backgrounds and encourage travel between offices to share perspectives. Some of our best ideas come from bumping into a visiting colleague at the office coffee bar. Markets move fast. Staying competitive as we’ve grown has required constant invention—of new trading strategies, technology, and processes. We’ve found this is easier when you hire humble, kind people. They tend to help each other, and prioritize teamwork over titles. We invest heavily in teaching and training. There’s a library and a classroom in every office, because deepening your understanding of something is considered real work. Guest lectures, classes, and conferences round out the intellectual exchanges that happen every day. People grow into long careers at Jane Street because there are always new and interesting problems to solve, systems to build, and theories to test. More than twenty years after our founding, it still feels like we’re just getting started.
