Amazon introduced the first Kindle in 2007 — at that time, it offered 90,000 eBooks and sold out 5.5 hours after the announcement. Since then, we have expanded to become the best-selling e-reader family in the world. We have also produced groundbreaking devices like Fire tablets, Fire TV, and more recently Amazon Echo and Alexa, the voice service that powers Echo and other devices so customers can play music, control their smart homes, and get information, news, weather, and more, using just their voice. The role: Are you seeking an environment where you can drive innovation? Do you want to play a key role in the future of Amazon's Devices business? We are a growing team in Amazon Devices working to prove new business ideas and continuously improving our delivery of new device features. We are looking for an engineer who is a technical leader and ready for a challenge, with an interest in working with machine learning scientists. Come and join our creative team of builders dedicated to building new consumer electronics! Working collaboratively, you will develop solutions to complex problems and engage with cross-disciplinary teams. As a Senior Software Development Engineer, you will have an opportunity to directly impact the customer experience, design, architecture, and implementation of products that will be used every day by people you know. We're looking for someone passionate about innovating on behalf of customers, who demonstrates strong product ownership and is willing to think in new ways to solve difficult problems. You will have track record of success in delivering new products, solving problems, and learning new technologies quickly. A commitment to teamwork, proactive approach to solving problems, and strong verbal and written communication skills are essential. Creating reliable, scalable, and high-performance products requires technical expertise, understanding of computer science fundamentals, and practical experience building large-scale distributed systems. This person is comfortable delivering quality solutions in a fast-growing environment where priorities may change rapidly.
