Research Scientist 1

Research Scientist – Level 3 The Level 3 Research Scientist serves as a senior technical expert, applying advanced scientific principles to drive research, innovation, and long-term technology development. This role requires deep subject matter expertise, leadership in scientific studies, and the ability to guide research efforts that may influence future products and capabilities years ahead of development.

Research Scientist 3

FULL_TIME

Demonstrated experience building supervised or weakly-supervised machine learning on real-world ("found") data, where you personally confronted the ground-truth/ labeling problem, not solely work on pre-labeled benchmark datasets. The unit of analysis is a window of packets, in effect, a field of packet bytes, much as an image is a field of pixels, and the central research problem is labeling the contents of that field: given a span of traffic, what is happening, is it an attack, and whose activity is it?

At Amazon, we don’t wait for the next big idea to present itself. We envision the shape of impossible things and then we boldly make them reality. So far, this mindset has helped us achieve some incredible things. Let’s build new systems, challenge the status quo, and design the world we want to live in. We believe the work you do here will be the best work of your life. 
Wherever you are in your career exploration, Amazon likely has an opportunity for you. Our research scientists and engineers shape the future of natural language understanding with Alexa. Fulfillment center associates around the globe send customer orders from our warehouses to doorsteps. Product managers set feature requirements, strategy, and marketing messages for brand new customer experiences. And as we grow, we’ll add jobs that haven’t been invented yet. 
It’s Always Day 1 
At Amazon, it’s always “Day 1.” Now, what does this mean and why does it matter? It means that our approach remains the same as it was on Amazon’s very first day – to make smart, fast decisions, stay nimble, invent, and stay focused on delighting our customers. In our 2016 shareholder letter, Amazon CEO Jeff Bezos shared his thoughts on how to keep up a Day 1 company mindset. “Staying in Day 1 requires you to experiment patiently, accept failures, plant seeds, protect saplings, and double down when you see customer delight,” he wrote. “A customer-obsessed culture best creates the conditions where all of that can happen.” You can read the full letter <a href="https://hiring.amazon.com/why-amazon/culture#/">here</a> 
Our Leadership Principles 
Our Leadership Principles help us keep a Day 1 mentality. They aren’t just a pretty inspirational wall hanging. Amazonians use them, every day, whether they’re discussing ideas for new projects, deciding on the best solution for a customer’s problem, or interviewing candidates.
