Job Description

Block's ML Platform team has one primary goal-- Make machine learning at Block easy.

Block has over 100 engineers and data scientists building machine learning solutions; our team's job is to support these efforts. We build model development tools, feature computation infrastructure, and high scale serving systems to ensure that those trying to use machine learning can spend less time on infrastructure and more time delivering value.

We build highly scalable systems that can serve our customers needs. Our systems have to be tough enough to stand up to the high scale load of processing all payments at square. Furthermore, our systems have to be flexible enough to enable data scientists to do their job. We sit in a unique spot, our team is an infrastructure one, but we work directly with Data Scientists daily. We get to learn directly from our customers and build new and better tools to directly improve their productivity and impact.

Within our team, we're looking for engineers to focus on building Block's Machine Learning systems.

Specifically you will:

• Build tools and systems that make data scientists and machine learning engineers happier and more productive. As an infrastructure team that supports both data scientists and engineers, we need people with both the DS/ML and engineering experience to understand the process and pain points of ML, and the engineering skills to build reusable, maintainable systems.
• Build highly scalable systems that can do the heavy lifting of feature processing. Our team maintains the infrastructure to compute real-time features used in the decision flows of all payments at square and the historical store that allows models to be trained. We need someone with experience with how to design and build flexible big data processing systems and knows how to move fast, but carefully, in production.

Qualifications

• A desire to design systems that solve our customer's problems; you want to understand your customer's needs.
• Create and lead large, strategic projects and mentor other senior engineers
• Produce scalable and robust production-quality code incorporating testing, evaluation, and monitoring.
• Experience designing and productionizing large-scale distributed systems built around machine-learned models and big data. Deep understanding of ML Ops and associated best practices are a plus.
• Experience using any of the major cloud vendors (GCP, AWS, Azure).
• Experience in using big data technologies like hadoop, spark, dataflow, and databricks.
• Experience with Enterprise / Open Source feature stores like Tecton, Feast a plus
• Bachelor's degree (or equivalent practical experience) and 12 + years of relevant industry experience
• An advanced degree focusing in computer science or other computational field is a plus.

Technologies we use:

• Java, Python, Google Cloud Platform, AWS, Snowflake
• Python ML stack (pandas, scikit-learn, Jupyter, etc.)
• Big data technologies like hadoop, spark, dataflow, databricks
• MySQL, Redis, Hibernate, jOOQ, Bigtable
