Frontend Engineer

San Jose, California


Love frontend development? Love open source? Love eBay? We believe you’ll love eBayUI!

eBayUI, as you may have guessed, is the official frontend platform team of eBay. The eBayUI team is responsible for a number of different tools that are used across hundreds of web applications at eBay — and many of these tools are open source, including including Marko, CoreUI, Skin and MIND Patterns.

We are specifically looking for a talented Engineer to help contribute to the next generation of the Marko platform. If much of this describes you, we’d love for you to join us.

  • You’re an expert in the fundamentals (HTML, CSS, JS) and you know the frontend ecosystem. When working on the platform, the fundamentals are… fundamental. And knowing the web ecosystem helps make sure our decisions aren’t made in a vacuum. Plus, we’re always looking for tools that could make our lives easier (and we don’t need to build ourselves!). Additionally, many teams look to us for advice on architecture/techniques/solutions and not just related to the tools we develop.
  • You care about accessibility and are familiar with accessibility principles and techniques. When designing our tools and APIs we need to ensure that we aren’t inhibiting our developers’ ability to build accessible products. We need to keep keyboard, screen-reader & other assistive technology users in mind. We strive to make all components accessible by default.
  • You’re knowledgeable of web development techniques like responsive design and progressive improvement. The components and tools we’re building are used across many different products in different browsers and on different devices.
  • Performance matters to you. You have a good understanding of CS fundamentals (like algorithmic complexity), how modern JS engines work, and performance techniques specific to the web. We want teams to be able to focus on building an exceptional product, not having to spend an inordinate amount of time optimizing things because the platform is consuming a significant portion of their performance budget.
  • You’re comfortable reading others’ code and quickly making sense of things. If a user is having an issue with one of our tools, sometimes the easiest thing is to clone down their repo, take a look, and help them do what’s needed or determine if there’s something we need to address. We also write integrations with other open-source tools, and even for tools that have phenomenal end-user docs, the plugin API docs can be… sparse. Being able to parse the code and find the right hooks is often necessary.
  • You like to share what you’re working on and what you’re learning with others. We work with teams all across the company, so good communication is key. Periodically we host “Brown Bag” talks to update developers on what’s new in the platform. With many of our projects being open source, we’re also working to sustain and grow the communities around these projects. We encourage pursuing outside speaking opportunities at conferences and meetups, as well as sharing ideas on the eBay tech blog and other mediums.

We use the following tools, so experience in these or similar tools is a plus.

  • Marko (similar: React, Vue, Svelte, etc.)
  • Less (similar: Sass, Stylus)
  • Git + GitHub (similar: GitLab, BitBucket)
  • npm
  • TravisCI (similar: CircleCI, Jenkins)
  • Mocha/Jest (similar: Ava, Tape)
  • Webdriver/Selenium (similar: puppeteer, playwright)
  • Testing Library
  • TypeScript
  • Babel
  • Lasso/Webpack/Rollup
