As a Principal Security Engineer, you will define the technical direction for this work, identifying the hardest unsolved problems, designing and prototyping new cross-domain threat detection ideas, and driving these new initiatives to completion across multiple teams and organizations. \nYou will operate with high autonomy in ambiguous spaces where the problems are not handed to you. You will work alongside software development engineers, data scientists, and security engineers, mentoring across job families, building consensus across teams on technical and security trade-offs, and raising the technical bar for the org. Your work will directly protect every AWS customer worldwide and help preserve our customers’ trust in us. The adversaries are real, the scale is unmatched, and our hardest problems are still unsolved.\nKey job responsibilities\nServe as an org-wide technical lead, setting technical direction, shaping long-term strategy, and increasing each team's productivity and effectiveness\nIdentify and prioritize the highest-impact security detection problems across the org, driving clarity in ambiguous spaces\nDesign and prototype new detection approaches, then drive them to production through engineering teams\nStay connected to all critical projects across the org, auditing technical decisions and providing guidance on work led by others\nMentor engineers across multiple job families and help managers guide the career growth of their team members\nSponsor cross-org technical initiatives with partner teams across Amazon Security and AWS, driving decisions forward and unblocking teams to ensure delivery\nBuild consensus across teams on important security and technical trade-offs, driving closure and alignment toward coherent outcomes\nIdentify, evaluate, and advocate for new technologies to improve threat detection and mitigation capabilities\nClearly communicate security risks and technical trade-offs to business leaders and non-technical stakeholders About the team You will help define the technical strategy for how Amazon detects and stops advanced threats, with the autonomy to identify the problems worth solving and an engineering org behind you to help build the solutions. You will identify threats and security risks that are not readily apparent to traditional detection approaches, proactively taking action before those risks materialize. You will write new threat detectors and automated mitigations to catch actual threat actors. You will work across Amazon and have direct influence on how AWS protects its infrastructure and customers. In addition to identifying new problems, you will frame the solutions, demonstrate their feasibility, and drive buy-in with leadership to get them funded, staffed, and delivered. The problems are real, the adversaries are sophisticated, and the impact you can make is global and immediate.\nBasic qualifications\nExperience performing security investigations, detection engineering, threat hunting, and/or incident response \nExperience with detection engineering and/or anomaly detection within security\nUnderstanding of Tactics, Techniques, and Procedures (TTPs) used by threat actors or groups\nKnowledge of security telemetry across 2+ domains (e.g., hosts, networks, cloud, physical security)\nAbility to develop code with at least one modern language, such as Python\nProven ability to provide technical and strategic leadership across multiple teams and/or within a large organization\nExperience communicating technical concepts to a non-technical audience\nCitizen within the EU\nPreferred qualifications\nExperience using common cloud services (IAM, Lambda, EC2, VPC, S3) for security response and/or automation\nExperience processing and analyzing security telemetry at scale \nExperience using machine learning and/or statistical methods for anomaly detection in security \nExperience with GenAI/LLMs applied to security workflows\nExperience working with software developers, data scientists, and/or product management teams Amazon is an equal opportunities employer.
