About the Position

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

• 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
