Principal Reverse Engineer - Product

About the Job:


As a Principal Reverse Engineer at Scrapinghub, your key objective will be to find sustainable and scalable solutions to power Scrapinghub's product offerings. You will be using reverse engineering, static, dynamic analysis in conjunction with Scrapinghub’s best in class tools including Crawlera, the world’s smartest proxy network, designed specifically for web crawling and scraping.


You’ll have a fair amount of autonomy in this role, but the responsibilities will likely include: establishing & maintaining technical and quality standards, and collaborating with other Scrapinghub teams to ensure that your work is having the biggest impact possible.


Your measures of success will be your ability to iterate quickly and produce knowledge that is useful to other Shubbers.



Job Responsibilities:



  • Reverse engineer obfuscated Javascript to understand the underlying browser fingerprinting techniques

  • Perform static, dynamic or concolic analysis and fuzzing to determine tracking behaviour

  • Create and execute well designed tests (repeatable, multiple treatments, testable variables, controls, replication)

  • Create best practice product usage guides and reports based on your findings

  • Drive creation of tools and workflows for prototyping successful and scalable solutions

  • Steer product and infrastructure changes based on your findings
