Principal Engineer, Frontend/Fullstack, Web

4 months ago

San Francisco, United States Square Full time

Company Description
Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn't work together.
To solve this problem, we expanded into software and built integrated solutions to help sellers sell online, manage inventory, book appointments, engage loyal buyers, and hire and pay staff. Across it all, we've embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale.
Today, we are a partner to sellers of all sizes - large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We're building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same.
Job Description
Square recently consolidated all members of our web front-end engineering discipline into a centralized organization, specifically to elevate our velocity and quality. Our high-level objectives include deprecating older JavaScript frameworks and standardizing on React, which will include a substantial migration effort. This is a transformational time to join our team as a Principal Engineer, to help establish the blueprint for modern and high velocity front-end development at scale, improving hundreds of engineers across the company
As a Principal Front-end Software Engineer on the Web team, you will:

  • Share ownership in Square's Dashboard web application - a surface used by millions of Square sellers to manage their businesses - ensuring we are proud to sign our names to the experiences we enable there
  • Work with other senior front-end engineers to establish and evangelize best practices and patterns with React
  • Prioritize and advocate for tooling and build investments to add leverage for every front-end engineer
  • Actively participate in reviewing technical documents and roadmaps to advocate for the right architectural tradeoffs
  • Advocate for process improvements within the team/organization in a critical, but thoughtful and empathetic way
  • Mentor engineers across the organization, evolving and instilling a culture of high quality and high velocity work


Qualifications

  • 15+ years of experience with JavaScript/TypeScript and modern web frameworks (specifically including ReactJS)
  • Extensive experience in web markup languages (HTML5 and CSS3), backend technologies such (NodeJS and Java), front-end build tools (Webpack, ESbuild, and Vite), and micro front-end architecture
  • Proven record of delivering large features (spanning ~1+ year) and large teams from start to finish with strong collaboration, communication, and ownership
  • Hands-on experience setting up and maintaining ReactJS applications with a substantial contributor base (dozens of active weekly contributors)
  • A track record of active contributions to front-end open source projects
  • Deeply comfortable with and able to apply software development design principles (SOLID, DRY) in daily work
