Software Engineer (Full-Stack) , Customer Data Platform

  • San Francisco, CA
  • 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

The Automation organization enables and measures the unified customer journey, intelligently empowering customers through Square's ecosystem of products. Customer Data Platform (CDP) Engineering is an essential team within the Automation organization that has two foci: First, building a state-of-the-art in-house infrastructure for collecting, unifying, and connecting customer data with applications. Second, building products and capabilities (e.g., for personalization, segmentation, data privacy management) that allow partners to easily integrate with CDP and help them use customer data to build remarkable solutions. CDP Engineering is an established team that has already made a great impact on Square's data infrastructure and is aspiring to transform Square into a truly data company.

We are looking for a software engineer (just like you!) to contribute to our technical vision and develop platform applications. You will use your engineering experience with full stack engineering (and, bonus, data platforms) to improve Square's data capabilities to grow our go-to-market strategy.

As a member of our team, you will:

  • Work with product and design to build platform applications to enable a variety of use cases such as personalization, self-servability, data governance, etc.

  • Provide technical direction for the full stack development for current and future products built on the platform.

  • Design and develop frameworks and patterns that will allow the team to develop new products quickly and scalably.

  • Design and build APIs and highly available services that deliver personalized, real-time merchant data and data governance controls to internal teams at Square.

  • Work closely with our cross functional partners such as data science and analytics teams to build and support platform functionality for their use cases.


You have:

  • Demonstrated excellence in any of the full stack frameworks with 4+ years of experience

  • Experience building component-based web apps with modern JavaScript front-end frameworks (e.g. React, Vue, Angular, or Ember)

  • Strong communication skills and ability to collaborate cross-functionally with other functions, such as designers, product managers, data scientists, marketing, and business partners

  • Experience designing and building APIs

  • A desire to be directly responsible for the lifecycle of engineering solutions. This includes leading the design and implementation of projects and organizing the team to achieve a remarkable solution

  • A love of data, data munging and care about building the right abstractions

  • A sense of customer empathy and desire to build great products

  • A strong desire to see your work have direct impact on the business

Nice to have:

  • Experience with any of the cloud platforms

  • Expertise with streaming technologies (Kafka, Pubsub, Kinesis) and log-based architectures and experience writing batch and stream processing jobs (i.e. Apache Beam, Google Cloud DataFlow, Apache Spark, Apache Storm)

Technologies we use:

  • JavaScript / Typescript / React


  • Ruby / Rails / MySQL / Redis
