About the Position

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

Additional 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 we’re detecting and mitigating vulnerabilities with intensity
  • 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 distil 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 4-5 years of experience as a security or operations engineer, with a technical background rooted in Windows
  • Experienced with maintaining, supporting and administering Windows and macOS platforms
  • Solidly understand common attack scenarios targeting the Windows platform, as well as protection technologies designed to mitigate and reduce associated risk(s)
  • Strong troubleshooter; familiar with trending and log analysis and have 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.)
  • 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
  • Comfortable with the Windows command line environment (PowerShell); scripting experience is a plus
  • Knowledge of macOS and mobile device security fundamentals is a plus
  • Fluent in English

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.
