Posted 2 days 1 hour ago by Amazon
Job ID: ADCI - BLR 14 SEZ - F07
Alexa is the voice activated digital assistant powering devices like Amazon Echo, Echo Dot, Echo Show, and Fire TV. To preserve our customers' experience and trust, the Alexa Sensitive Content Intelligence (ASCI) team builds services and tools through Machine Learning techniques to detect and mitigate sensitive content in Alexa.
We are looking for a passionate, talented, and inventive Data Scientist-II to help build industry-leading technology with Large Language Models (LLMs) and multimodal systems. You will be working with a team of exceptional Data Scientists in a hybrid, fast-paced organization where scientists, engineers, and product managers collaborate to build customer-facing experiences. You will analyze and automate processes for collecting and annotating LLM inputs and outputs to assess data quality and measurement.
You will apply state-of-the-art Generative AI techniques to analyze how well our data represents human language and run experiments to gauge downstream interactions. You will work collaboratively with other data scientists and applied scientists to design and implement principled strategies for data optimization.
A Data Scientist-II should have a good understanding of NLP models (e.g. LSTM, LLMs, other transformer-based models) or CV models (e.g. CNN, AlexNet, ResNet, GANs, ViT) and know ways to improve their performance using data. You will leverage your technical expertise in improving and extending existing models, directly impacting our customers through products and services that utilize speech, language, and computer vision technologies.
You will be part of a select group of people producing one of the most highly-rated products in Amazon's history, so if you are looking for a challenging and innovative role where you can solve important problems while growing in your career, this may be the place for you.
A day in the life
You will work with a group of talented scientists on running experiments to test scientific proposals/solutions to improve our sensitive content detection and mitigation for worldwide coverage. This will involve collaboration with partner teams including engineering, PMs, data annotators, and other scientists to discuss data quality, policy, model development, and solution implementation. You will collaborate and contribute to extending and improving solutions for the team.
The mission of the Alexa Sensitive Content Intelligence (ASCI) team is to (1) minimize negative surprises to customers caused by sensitive content, (2) detect and prevent potential brand-damaging interactions, and (3) build customer trust through appropriate interactions on sensitive topics.
The term "sensitive content" includes a wide range of categories such as offensive content (e.g., hate speech, racist speech), profanity, content suitable only for certain age groups, politically polarizing content, and religiously polarizing content. It refers to any material exposed to customers by Alexa (including both 1P and 3P experiences) and includes text, speech, audio, and video.
- 3+ years of data scientist experience
- 3+ years of experience with data querying languages (e.g. SQL), scripting languages (e.g. Python), or statistical/mathematical software (e.g. R, SAS, Matlab, etc.)
- 3+ years of experience with machine learning/statistical modeling data analysis tools and techniques, and parameters that affect their performance
- Experience applying theoretical models in an applied environment
- Experience with big data: processing, filtering, and presenting large quantities (100K to Millions of rows) of data
- Experience in Python, Perl, or another scripting language
- Experience diving into data to discover hidden patterns and conducting error/deviation analysis
