Senior Software Engineer, Data Infrastructure

  • San Francisco, CA, USA
  • Full-time

Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

Good decision-making is only possible when you have all the data available, along with the right tools and systems to process and analyze that data. The Data Infrastructure team works on systems handling hundreds of terabytes daily, and plays a pivotal role in driving the Square data ecosystem by managing core infrastructure and providing core data pipeline services.

You are an experienced software engineer, ready to bring your skills towards building (modern / next generation) data solutions. As an engineer on the Data Infrastructure team, you will:

  • Write performant, clean, modern applications and services in Java or Python, possibly migrating functionality from existing Ruby/Rails services.
  • Improve operations and tooling around Kafka, leveraging open source software as appropriate to ensure we can continue to scale.

  • Modernize the application event logging infrastructure, and move it to a streaming architecture.

  • Build out new data management capabilities like granular data access, more sophisticated data security policies, and improving data discovery and documentation and overall data governance.

  • Mentor fellow teammates in different ways: implementation and code review, architecture and design, devops and operational best practices, and in any other way where you have interest and expertise.

  • Be self-driven in identifying and documenting feature gaps, and designing and implementing solutions to them.


  • 7+ years of software development experience.

  • Strong expertise with Python or Java.

  • Bachelor’s degree in computer science or equivalent practical experience.

  • Bonus: Kafka experience, either as a client or as an operator.

  • Bonus: Ruby/Rails experience.

  • Bonus: Docker, Kubernetes, Terraform, or AWS experience.

  • Bonus: a desire for leadership responsibilities, such as a tech lead.
