Jupiter (YC S19) | Senior Machine Learning Engineer and Full-Stack Product Engineer | Full-Time | SF/Remote

At Jupiter, we’re on a mission to build grocery shopping from the ground up, the way it was meant to be built - to be automated, personalized, and fun. In applying best-in-class machine learning and data science to this problem, we aim to create the most profitable and sustainable grocery store. We're based in San Francisco and backed by Khosla Ventures, NFX, Canaan Ventures, Switch Ventures, Paul Buchheit, and Y Combinator.

Our goal is to make the experience of buying groceries and planning meals feel as seamless as paying for running water. By keeping track of product preferences and sharing recipes within a unified, “multiplayer” grocery platform, we aim to play a role in reducing the 8 million tons of food that go to waste every year due to spoilage by building the most personalized, comfortable grocery experience for working families.

Joining as a full-time member of our engineering team, you'll dive right into our TypeScript/Kotlin/Python stack and have a say in making foundational design, infrastructure, and architecture decisions. You should have a strong background in building human-centered products from the ground up. You'll have the opportunity to marry operations with data through a beautifully-crafted user interface to create the most personalized predictive experience for our hundreds of homes in San Francisco.

Whether you’re a dedicated streamer or still clinging to the cord, by now you know that Roku is the #1 streaming platform in North America (with our sights set on helping the world cut the cord). But what is it like to work at a company that expects to grow by 50% in 2021? We chatted with Software Engineering Director Hugo du Plooy in our San Jose office and he told us what something surprising: Roku’s success is all based on working together as a team rather than as a collection of egos. https://youtu.be/tqf8c8u-p2k

In this role you will work as a key member of Data Activation team. You will design, develop, and operate components of our system to create a privacy compliant and performant way to manage data using big data technologies like Druid, Map-Reduce, Hive/Presto, Kafka, Spark, and Aerospike.
