Company Description
Square builds common business tools in unconventional ways so more people can start, run, & grow their businesses. When Square started, it was difficult & 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 & software products including Square Capital, Square Terminal, Square Payroll, & more. We're working to find new & 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 API Platform team creates tools that both external & internal developers use to build apps on Square's platform. We are a small, focused, & rapidly growing team with an abundance of growth & impact opportunities.

Our products & responsibilities include:

  • SDK generation for multiple platforms
  • Building React Native & Flutter components that developers can easily incorporate into their apps
  • Rich sample applications that developers can use as building blocks or starting points
  • API Frameworks that enable internal teams to publish their APIs faster & easier
  • Testing platforms for our external developers
  • Frameworks for Square's public Webhooks

As a software engineer on the API Platform team, you will own the design, creation, & maintenance for all of the above. You will have the opportunity to participate in the community of developers who build on the Square Developer Platform & use that knowledge along with usage data to create new tools & components as well as adapt existing ones to meet the needs of our developer customers.

You will:

  • Help build our Developer Platform, for use by millions of Square Sellers & a key strategic asset of Square.
  • Design & implement easy to use tools & reusable components, making thoughtful tradeoffs between consistency & availability when both are not possible.
  • Work cross-functionally with our product teams, *many* other engineering teams, & partner developers to design & implement Squares global developer platform.
  • Build systems that maintain customers sensitive data & hold Square to the highest standards for security & compliance.
  • See the big picture to design fault tolerant systems so the team can be brave, move fast, & break things, without ever showing a negative impact to customers.
  • Take input from & work with our developer community on Square SDK projects & contribute to other projects as appropriate.


You have:

  • BA/BS degree or equivalent practical, working experience (4+ years preferred)
  • A strong sense of customer empathy & desire to influence the product direction
  • Innate curiosity & a desire to be responsible for all aspects of building Square's developer platform in a small, highly focused, & very rapidly growing team.
  • Understanding & curiosity in creating well thought out, scalable, low-latency, global systems.
  • Been self-driven, open to collaboration & willing to grow as an engineer

Even better if you are experienced in:

  • React Native & / or Flutter
  • Cross-team & cross-functional collaboration
  • Creating SDKs, APIs, & developer tools
  • Working collaboratively or contributing to open source projects
