Company Description

Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block.

Job Description

Block began with a simple yet revolutionary piece of hardware—the Square Reader. We have expanded that vision to give our merchants access to the latest secure payment technologies (contactless and chip cards) and easy-to-use Point of Sale products. Today our hardware carries over $30 billion in transactions annually. Measuring the performance of our hardware, and the journey in getting the hardware to our merchants, is essential in ensuring that our merchants’ experience with Square is as seamless as possible.

We need your help to collect data about our hardware, organize that data, and make it available to analysts across Block. As a member of the Hardware Data Engineering team, you will define, develop, and manage a variety of data infrastructure components and pipelines so that our analytics teams and collaborators have trusted data to inform decisions and insights.

You will:

  • Join the small but mighty Hardware Data Engineering team that partners with hardware data consumers to understand their needs and to source the right data sets to work on
  • Work in a remote environment that allows you to build scalable hardware data pipelines and tools to ingest data from internal/external sources to our cloud data stack (Snowflake / AWS)
  • Develop data structures to support flexible analysis of this data, including creating data models, structuring optimized ETLs, designing validation scripts
  • Develop platform infrastructure and data services/components to support data engineering automation and data quality initiatives
  • Troubleshoot technical issues with platforms, data discrepancies, alerts, etc.
  • Be a voice between Block’s Hardware teams and Block's data community. Help the Hardware team’s data producers embrace best-practices, represent the Hardware team’s voice in data infrastructure planning discussions
  • Report into a Data Engineering Manager on the Data Lifecycle team within Foundational Engineering



  • 5+ years building and supporting reporting data systems built on columnar oriented RDBMS systems (e.g. Snowflake, BigQuery, Redshift, Vertica, etc.)
  • Strong experience building data pipelines from heterogeneous data sources (e.g. Event streams, Flat Files, RDBMS, REST APIs, SFTP, etc.) to support real-time operational and analytical workloads
  • Technical accomplishments working with SQL, ETL, and Apache Airflow; and knowledge of at least one mature programming language (Ruby (and Rails), Python, Java, Go, or similar)
  • Experience with Linux/OSX command line, version control software (git), and general software development
  • Experience with cloud based data tools and services (e.g. AWS Lambda/S3/Transfer, GCP Cloud Functions/GCS, Fivetran, etc.)
