Description Join us to advance the state-of-the art in database technology and serve customers all around the world. Our team develops Amazon DocumentDB (with MongoDB compatibility), a fully-managed cloud database that enables customers to persist JSON documents and retrieve them with a powerful query language. We are developing new query capabilities, pushing the bounds of performance, driving distributed systems innovation in scalability and high availability, and investing in user experience. As a senior engineer on the team, you will collaborate with colleagues on research, prototyping, software design, and implementation. Our technical problems span all aspects of database systems – multiversion concurrency control (MVCC), transactions, query optimization, data storage, indexing, parallel computation, wire protocol translation/compilation – as well as distributed systems, telemetry, build and deployment technology, and API and UI design. You may choose to focus on an area, work across areas, or rotate over time. You will have the opportunity to interact with customers and to work with product managers to define product improvements. You will solve hard problems, grow your skills, and mentor others along the way. If you are excited by the prospect of making it easier for customers to store, query, and analyze data at scale; if you are interested in databases, operating systems, distributed systems, and/or developer tools; and if you are looking to work with teammates to propose ideas, experiment, learn, and build great software – we would love to hear from you. Inclusive Team Culture Here at AWS, we embrace our differences. We are committed to furthering our culture of inclusion. We have ten employee-led affinity groups, reaching 40,000 employees in over 190 chapters globally. We have innovative benefit offerings, and we host annual and ongoing learning experiences, including our Conversations on Race and Ethnicity (CORE) and AmazeCon (gender diversity) conferences. Amazon’s culture of inclusion is reinforced within our 14 Leadership Principles, which remind team members to seek diverse perspectives, learn and be curious, and earn trust. Work/Life Balance Engineering is a marathon, not a sprint. We operate sustainably, with teams in control of their priorities, commitments, and processes. Operational load is reasonable, and we prioritize root cause resolution to keep it that way. Our team puts a high value on work-live balance. It isn’t about how many hours you spend at home or at work; it’s about the flow you establish that brings energy to both parts of your life. We believe striking the right balance between your personal and professional life is critical to life-long happiness and fulfillment. We offer flexibility in working hours and encourage you to find your own balance between your work and personal lives. Mentorship & Career Growth Our team is dedicated to supporting new members.
