About the role

Original posting from Jane Street

About the position

We are looking for an enthusiastic, motivated and technologically curious individual with a Windows security focus to join Jane Street's IT Security team. Our team is dedicated to securing the firm's Windows and macOS computing platforms, which you will contribute to through a combination of technical hands-on work, cross-team collaboration and creative problem-solving.  Responsibilities of this role will include: 

Deploying, documenting and supporting our security controls at scale

Acting as a key contributor to our vulnerability management programme, ensuring vulnerabilities are rigorously detected and mitigated

Providing security guidance and support to the broader IT department as well as our IT Operations Team as security incidents arise

Developing both technical and non-technical solutions in collaboration with engineering teams that address security concerns

Contributing to the development of our team’s operational playbooks, procedures, guidelines and technical security standards

We’re looking for someone who fully enjoys working with and being around people, takes pleasure in triaging complex problems and is able to delegate and escalate tasks effectively. This role is anything but siloed; we’ll rely on you to be a key liaison between the IT Security team and other internal technology groups to distill and communicate pertinent information. While we’re open to individuals from a range of backgrounds, someone who’s worked in a code-driven environment and has hands-on experience with security incident response is preferred. 

About you

Have 5+ years of experience as a security or operations engineer, with a technical background rooted in Windows

Experienced with maintaining, supporting and administering Windows platforms at scale, including Active Directory and Group Policy

Solidly understand common attack scenarios targeting the Windows platform, as well as the protection technologies designed to mitigate them

Strong troubleshooter, comfortable triaging security incidents and production issues; familiar with trend and log analysis, with hands-on experience using system monitoring and alerting tools to identify production disruptions

Have hands-on experience deploying and implementing endpoint security controls at scale (anti-malware, EDR, application control, log aggregation, host-based firewalls, disk encryption, etc.)

Comfortable with PowerShell, including experience scripting or building tooling to automate security tasks

Knowledge of macOS and mobile device security fundamentals is a plus

Excellent written and verbal communicator; able to explain processes clearly to colleagues across the firm

Comfortable working in an environment with shifting priorities

Collaborative and approachable; eager to be a team player
