A bit about us

Lever was founded nine years ago to tackle the most strategic challenge that companies face: how to recruit and hire top talent. We’re building the next generation of hiring software that companies like Netflix, Atlassian, KPMG, and McGraw-Hill Education rely on to grow their teams. We’ve rethought the talent acquisition paradigm and are the innovation leaders in our space and looking for the right people to join us as we scale.

We’re extraordinarily proud of the company we’ve built so far (not to mention humbled to be recognized as the #1 place to work in San Francisco, as well as a top workplace in the entire United States). Our people are Lever’s biggest competitive advantage and we’ll continue investing in our “Leveroos” and people-first culture.

The challenge

Lever Hire, Lever’s primary application, is built on top of DerbyJS. DerbyJS is a real-time web framework originally created by Lever founder Nate Smith. After taking on the role of CEO in April this year, Nate is spending more time running the company and less time working on Derby.

This is where you come in. You will help evolve the framework to better serve the needs of its current users at Lever and beyond.

The opportunity

As a framework engineer, you will be able to build on the foundational software that powers all of Lever’s features. You will have the chance to work directly with brilliant teammates on the framework team, and you will have the opportunity to collaborate with the product engineers who use Derby to build features. As part of your daily work, you will apply and build expertise in JavaScript performance. You will learn about (and improve) a battle-tested Operational Transform algorithm that enables Derby’s real time features. As an open-source framework author, you will also be able to engage with the community through blog posts and conference attendance.

The team

The framework team is small but mighty. You will be joining another Staff engineer to double the size and impact of the team.

You will collaborate closely with a product engineering team that champions cross-functional empathy. You will work directly with an Infrastructure engineering team that is constantly improving the way Lever’s systems operate. You will consult and help guide the engineering, product, and design teams as we build a Lever that helps companies connect human potential to meaningful work.

The skill set

  • A love of JavaScript with professional experience writing features in the browser and node.js
  • A deep understanding of the JavaScript language and how to make JavaScript code perform well
  • A desire to teach others with the communication skills needed to effectively share knowledge
  • Empathy for the framework users within Lever’s engineering team and empathy for the Lever customer
  • Experience or desire to write blog posts and speak at conferences
  • 5+ years of professional experience

Within 1 month, you’ll
