Job description: DESCRIPTION

Job summary

At Amazon, we are obsessed with earning customer trust. The People Experience and Technology (PXT) Security team enables our PXT business leaders to maintain customer trust by keeping HR systems and their underlying employee, contingent worker, applicant, and candidate data secure.

PXT Security’s Defensive Security Team is looking for a passionate, innovative, and results oriented security engineer who has a strong passion for security at scale to help keep Amazon PXT’s applications and services secure. This team is responsible for onboarding PXT applications and services to a security log monitoring platform, which helps in detecting unauthorized user behavior, and alerting PXT application teams when potentially abusive behavior is detected. Our team also partners with PXT application teams to remediate weaknesses, and sharpen our software development lifecycle.

In this role, you will be asked to solve complex technology problems, build tools to automate your way out of manual efforts, and influence how PXT services protect, detect, and respond to adversaries, and mitigate security threats to protect HR data. You will be in direct contact with PXT teams across business verticals, giving you first hand knowledge about how Amazon PXT is built and operates. Additionally, you will leverage the knowledge you gain to find new ways to drive improvements to PXT’s services, processes, and programs. Further, you will be backed up by a team of highly-skilled security engineers, all working with a singular focus of maintaining our customer’s trust.

A person in this role must show exemplary judgment in making trade-offs between short-term fixes and long-term security and business goals. They must also demonstrate resilience and navigate ambiguous situations with composure and tact. Above all else, a strong sense of customer obsession is necessary to focus on the ultimate goal of keeping Amazon and its customers secure.

  • Work independently but collaborate with cross-functional teams (e.g., threat intelligence, incident response, software development, QA, Project/Release Management, Build and Release) to provide security engineering consulting and control design recommendations to reduce risk
  • Identify and drive new initiatives to expand automatic security analysis to find the critical problems of the present and the future
