About the Job

Requirements

  • Hands-on vulnerability management experience in a substantial environment, including experience with an automated scanning platform such as Rapid7, Tenable, or Qualys.
  • Understanding of how scanning, asset inventory, and remediation tracking fit together.
  • Ability to automate work, maintain code and configurations in version control, work under code review, and produce maintainable solutions.
  • Ability to query and shape data and build and debug data pipelines and integrations handling messy, inconsistent inputs.
  • Ability to reason about trade-offs and context, apply threat modeling, and prioritize findings according to exploitability and exposure.
  • Knowledge of current cybersecurity developments and the ability to distinguish meaningful day-to-day risks from interesting but lower-impact hacks.
  • Understanding and practice of good personal cybersecurity hygiene, with the ability to discuss it with others.
  • Ability to communicate clearly across audiences and document work so others can follow.
  • Ability to collaborate positively and bring others along when implementing cybersecurity practices.

Responsibilities

  • Support and improve the vulnerability management lifecycle end to end, from discovery and validation through triage, assignment, remediation tracking, and verification.
  • Review new findings from automated scanning tools, threat intelligence, and security advisories, and prioritize them based on exploitability and exposure.
  • Validate and deduplicate findings across sources, confirm whether affected products or components are present, and route work to the team that owns the fix.
  • Measure scanning coverage and data quality, identify unscanned assets, stale scans, and authentication failures, and avoid assuming coverage is complete.
  • Drive automation across vulnerability management tooling and processes.
  • Broaden scanning coverage across asset classes, including evaluating and migrating scanning platforms as needed.
  • Integrate software inventory and software bill of materials data to identify where vulnerable components are used across software.
  • Build dashboards and metrics measuring coverage, service-level agreements, and progress.

About the Company

Jane Street

Trades stocks, bonds and funds as a market maker

Jane Street trades stocks, bonds, options, and exchange-traded funds with its own money as a market maker, a firm that constantly quotes prices to buy and sell so other investors can trade whenever they want. In 2025, it made more money from trading than JPMorgan Chase or Goldman Sachs, the biggest trading banks on Wall Street. Its traders, researchers, and engineers build computer-driven strategies that trade on exchanges and other venues around the world, and it also trades directly with large institutional clients. It earns the small gap between buying and selling prices across huge volumes, plus gains on positions it holds for minutes to days. Jane Street was founded in 2000 and is based in New York.
