Job description
About the Position
We are looking for an Infrastructure Security Engineer with a strong Windows engineering background and practical exposure to modern platform security controls to help our global team secure Jane Street’s IT platforms. In this role, you’ll need strong judgement and discerning taste to prioritise potentially complex and extensive remediation efforts. You'll help decide where we focus our resources, providing technical advice and making decisions on behalf of the group where needed. We're looking for builders: people who spend their time writing code and automation (e.g. PowerShell modules, Python) and integrating security products via their APIs, rather than primarily configuring and operating the tools themselves.
In this role, you will proactively propose, design, test, implement and document strategic security controls. You will coordinate and deliver security solutions across our IT platforms while identifying opportunities to further automate intelligent workflows. You will help secure internal IT and remote working platforms through a combination of hands-on technical work, consultancy and security influence to the wider IT team. This role will encompass a range of responsibilities, including building security controls that scale, investigating emerging threats, developing new security tooling and driving vulnerability management initiatives.
This position sits within our IT Engineering group, a highly dedicated team of engineers who monitor and manage our environment across a physical/virtual computing landscape that spans three continents. Your analytical thinking and expertise will be invaluable as we support the daily work of our colleagues and keep our systems operating at the highest standard.
