Casper is hiring a

Software Engineer

New York, United States


Casper is looking for a backend developer with strong Ruby skills to join our engineering team. Working in our ops pod (a sub-team within tech devoted to operations), you’ll be building the backbone of the company. Our operations team is investing in our service-oriented architecture while continuing to support the needs of our rapidly growing business, which is looking to add new products, services, fulfillment options, you name it. As an early member of this team, you’ll have a huge role architecting our constellation of services and defining how we work as a team in creating a technical ecosystem we can all be proud of.

Key Responsibilities

  • Design and develop features for the ruby on rails apps that comprise our network of services
  • Write tests for those features, thorough tests that are structured well enough to serve as documentation
  • Integrate our applications with 3rd party API’s using careful encapsulation that prevents us from becoming wedded to any one partner
  • Collaborate with other team members in designing individual apps and the network as a whole
  • Participate actively in our agile workflow and think critically about what we can do to improve the way that we work as a team
  • Think creatively about ways to improve the business as a whole, and be ready to take ownership over their implementation


Our ideal candidate is highly motivated, and able to manage their own time effectively. You should be very opinionated about the software you build and the tools you use, and be willing to debate the choices we make as a team (in the spirit of collaboration of course!). You should also have:

  • A degree in Computer Science
  • Proficiency in Ruby
  • Experience interfacing with 3rd party APIs
  • Experience building reusable functional interfaces
  • Experience with Rails or another MVC web framework
  • Comfortable working with Unix command line tools and version-control tools like git
  • Experience building and expanding web platforms through periods of high growth
  • Experience in ecommerce is a plus

About Casper

Casper ( is a sleep brand that launched in 2014 with one perfect mattress sold directly to consumers — eliminating commission-driven, inflated prices. Its award-winning sleep surface was developed in-house, has a sleek design, and is delivered in a small, "how did they do that?" sized box. A year and a half after launching the mattress, Casper expanded its universally comfortable product line, which now includes a perfect pillow and sheets.

Now expanding into Europe, the company is one of the fastest growing consumer brands of all time with more than 100 full-time employees, $100M in revenue for 2015, and 100,000 Casper owners. Casper was named one of Fast Company's Most Innovative Companies in the World, and its eponymous mattress was crowned one of Time's Best Inventions of 2015.
