Job Description

The Developer Productivity Experience (DPX) team owns the building of all production artifacts from 10s of millions of lines of source code. In doing so, hundreds of thousands of VMs are spun up each day to build and test features and do final validation of the code before it is run in production. At Salesforce scale, it is not just about checking everything but checking the right things at the right time to provide confidence in our software. Our mission is to make developers more productive with a reliable system and actionable data. Examples of the questions we are trying to answer include:

• You have 1.2 million tests and you only have time to run 1% of them in 1 hour. Which ones do you choose
• Using data on test executions, the source code, production stack traces, and how developers respond to failures (e.g. which test failure do they look at first), how do you assess the value of the test?
• A complex piece of software is modified by hundreds of teams simultaneously, how can you assign a numerical value to the risk of a particular change?
• Looking at production stack traces, how do you identify patterns and associate them with the source code?
• You have hundreds of microservices that depend on each other and an integration test is failing. How do you create and assign bugs to the right team?

A Data Scientist with our team must possess both the AI/ML skills to improve the performance of our classifiers and recommender systems, as well as engineering skills to build and deploy a production-quality service.
