Software Dev Engineer III, SAIF Data

Full Time
Job summary
Alexa AI, the speech processing and personal assistant technology behind Amazon Echo, is seeking an SDE III for our Data Experience organization. At Alexa's Secure AI Foundation (SAIF) Data, we build the data services that enable the fast, secure, and massive scale ML that delivers delightful Alexa interactions to users.

The Data Experience team enables Alexa machine learning scientists, software engineers and BI analysts to securely, easily, quickly and cost-efficiently access, transforms, and build models with data in the vast Alexa data lake. As a member of the Data Experience team, you play a critical role in delivering the life blood of AI - data - to the Alexa AI community to help tackle the most cutting edge conversational AI problems at the largest scale few places in the world can match.

The Data eXperience (DX) team, is responsible for our SAIF Data Development Kit, increasing the rate of experimentation by delivering services that enable our customers to optimize their data storage, preparation, and deep dive analysis at low latency access from training infrastructure with intelligent APIs and clients for running big data Spark and SQL jobs working with data from modeling environments. This enables communities of Modelers spanning product areas to collaborate efficiently through sharing and building upon each other's artifacts, to expand collective intelligence. The team owns our Data Preparation SDK, enabling Modelers to train on petabyte scale data sets in days instead of weeks, at a quarter of the prior cost, making frequent training and experimentation of enormous data sets feasible and cost effective, while also opening the door to experimentation with data sets orders of magnitude larger than previously possible.

In the SAIF Data organization, you will work in a highly collaborative and supportive environment across all stages of an agile software development lifecycle, including architecture design, development, documentation, testing, and operations. You will build ML services using AWS at huge scale found nowhere else. Your efforts will support the successful and well-loved Alexa powered products. Our combination of challenging technical problems, critical services, and a quickly growing organization will provide you with unique opportunities for career growth.

Key job responsibilities

What you'll be doing:

Solve distributed systems problems at Alexa scale.

Design, implement, and operate large scale 24x7 services using Java, Python, and AWS services such as EC2, S3, Kinesis, Lambda, DynamoDB, and many more.

Collaborate with AWS solutions architects and other software engineers. Our team is the largest customer of several AWS offerings in the world, and we are constantly testing the limits of those offerings.

Provide technical guidance on software design, architecture, patterns and practices.

Help your team self-organize and create software development processes and practices that will work best for you and your teammates.

Build relationships with your customers, partner teams, and the engineers on your team.

Your background and who you are:

You have experience reliably delivering high-quality, distributed, testable, and scalable software. You are driven by delivering value to your customer.

You love to work with teams that are always raising the bar. You believe that a team is strongest when it is diverse and includes multiple perspectives.

You enjoy the challenges of highly technical problems that you define and solve in real time.

You believe that there are multiple ways to solve a problem, each with different trade-offs. You don't typically think in terms of the "right" or "wrong" way to do something, but rather the most effective path given the current constraints.

You are excited by the technical challenges of large scale service development from architectural design, to implementation, to operations.

You put yourself into your customer's shoes and immerse yourself in the customer experience to understand how to serve them better.

You've made mistakes in the past, have learned a lot from them, and apply these learnings regularly.

You want to have an impact on a hugely successful and growing product that improves people's lives.
