Software Development Engineer (ML), EU International Technologies - Luxembourg | Amazon Job

Job Description

As an engineer on our team, you will take on a key role in improving capabilities of the Amazon product search service, and ensure we offer top-quality recommendations for all our customers regardless of their location or language. We help customers find the products they are searching for, and discover new products they would be interested in, by developing ML models trained on terabytes of product and traffic data to improve query understanding, ranking of search results, and personalization. We are seeking a software engineer who will assist in deploying those ML models, integrating them into existing services, and optimizing their performance. You will do so by building robust pipelines to train, evaluate, and deploy our models.

This is a rewarding role where you will be able to draw a clear connection between your work and how it improves the experience of millions of Amazon customers across the globe every day. You can also expect to have excellent opportunities, and ample support, for career growth, development, and mentorship. The team is a mixed science/engineering group, with each team member able to contribute to both engineering excellence as well as scientific innovation.

Key job responsibilities
- Design and implement new features across the various software components powering our search system
- Participate in the design and deployment of robust and scalable pipelines for data processing, model training, and model inference
- Build and configure metrics, dashboards, and alerting mechanisms for our deployed services and models
- Work closely with ML experts on your team to identify improvement opportunities and tackle technical obstacles
- Coordinate with engineering counterparts in other teams and stakeholders we work with

A day in the life
You will collaborate with scientists who build ML models trained on terabytes of data, and integrate these models into the production search engine that serves customers, closing the loop through design, implementation, deployment, and monitoring. The chosen approaches for model architecture will balance business-defined performance metrics with the needs of millisecond response times.
