Job Description

Job Description:

GTTS (Global Transportation Technology Services) builds products that help Amazon run the world's largest transportation network, using cutting-edge technologies and machine learning, all running on AWS. We are looking for someone who is passionate about technology, loves solving customer problems, and delivers the high quality work that we expect for critical systems at Amazon.
In GTTS we embody the culture of a scale-up but still assume the responsibility of building and running products at the scale and criticality of Amazon. We follow agile development practices, working closely with customers, failing fast, and continually looking for new ideas from within and without Amazon. We proactively deprecate legacy systems to reduce the burden of technical debt, and regularly develop new-greenfield-products.
As a SDE in GTTS, you will work on challenging engineering problems, processing large datasets, and building products that are performant, scalable, and robust to support critical transportation processes. You build web applications that delight our customers, and complex data pipelines to process the data that serves them. We will give you the space to explore new technologies and approaches, and apply them to customer problems. We build products that solve customer problems and have a direct (financial) impact on the transportation network. We always work backwards from the customer.
As a SDE, you provide technical leadership at Amazon. You help establish technical standards and drive Amazon’s overall technical architecture, engineering practices, and methodologies. You think globally when building systems, ensuring Amazon builds high performing, scalable systems that work well together. You are hands on, producing both detailed technical work and high-level designs.
In GTTS we operate the products that we build. During the on-call week, you will provide front-line support if any critical issues arise with the team's products.
