Job Description
Alexa is the voice activated digital assistant powering devices like Amazon Echo Echo Dot Echo Show and Fire TV which are at the forefront of this latest technology wave. To preserve our customers experience and trust the Alexa Sensitive Content Intelligence (ASCI) team builds services and tools through Machine Learning techniques to implement our policies to detect and mitigate sensitive content in across Alexa.
We are looking for a passionate talented and inventive Data Scientist to help build industryleading technology with Large Language Models (LLMs) and multimodal systems requiring good learning and generative models knowledge. You will be working with a team of exceptional Data Scientists working in a hybrid fastpaced organization where scientists engineers and product managers work together to build customer facing experiences. You will collaborate with other data scientists while understanding the role data plays in developing data sets and exemplars that meet customer needs. You will analyze and automate processes for collecting and annotating LLM inputs and outputs to assess data quality and measurement.
You will apply stateoftheart 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.
Key job responsibilities
As a Data Scientist in the team you should have a reasonably 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 of ways to improve their performance using data. You leverage your technical expertise in improving and extending existing models. Your work will directly impact our customers in the form of products and services that make use of speech language and computer vision technologies.
You will be joining a select group of people making history producing one of the most highly rated products in Amazons 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
As a Data Scientist you will be working with a group of talented scientists on running experiments to test scientific proposal/solutions to improve our sensitive contents 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 work with other scientists collaborating and contributing to extending and improving solutions for the team.
About 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 branddamaging interactions and 3 build customer trust through appropriate interactions on sensitive topics.
The term sensitive content includes within its scope a wide range of categories of content such as offensive content (e.g. hate speech racist speech) profanity content that is suitable only for certain age groups politically polarizing content and religiously polarizing content. The term content refers to any material that is 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 data querying languages (e.g. SQL) scripting languages (e.g. Python) or statistical/mathematical software (e.g. R SAS Matlab etc. experience
3 years of machine learning/statistical modeling data analysis tools and techniques and parameters that affect their performance experience
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
Bachelors degree in computer science mathematics statistics machine learning or equivalent quantitative field
Experience in Python Perl or another scripting language
Experience diving into data to discover hidden patterns and of conducting error/deviation analysis
