About The Position

Are you passionate about building the next generation of data infrastructure that powers security insights and analytics at scale? Do you want to lead the modernization of a security data platform that enables measurable improvements in application security across Amazon? As a Senior Data Engineer on the AppStar DNA team (Data & Analytics Engineering), you will be a technical leader driving our data platform evolution—a strategic effort to modernize our security data infrastructure into a scalable, semantically rich, and operationally excellent data ecosystem. You will define and own data architecture at the team level, working across multiple data domains to build the foundational data infrastructure that powers the AppStar organization. This is not a role where you inherit a finished system—you will architect and lead the transformation. You'll work at the intersection of large-scale data engineering, modern lakehouse architectures, and security domain expertise to build a unified Security Data Model that serves as the backbone for analytics and reporting use cases. You should be a builder who thinks in terms of architecture, not just code. You thrive in ambiguity, proactively identify and solve systemic data problems, and set engineering standards that raise the bar for your team. You bring deep expertise in data modeling, ETL/ELT pipeline design, and distributed data systems, and you combine that with strong business judgment to make the right trade-offs between short-term delivery and long-term platform health. Amazon is continuously innovating new services and features for our customers. Our engineers invent, build, and sometimes break things to make them easier, faster, better, and more cost-effective. However, no matter what we're building—from websites to web services, AR to AI, drones to devices—security is always our top priority. The Amazon Application Security team focuses on working with our builders to provide experiences that our customers can trust. That means constantly learning new things and solving complex problems to protect the safety, security, and privacy of billions of lives on a global scale. At Amazon, you'll be working with the best minds in technology and security. Learn and be curious here, and accelerate your career growth. You can take pride in knowing that your work is meaningful, having a positive impact on others and making the world a better place.
