Who we are

We are a rapidly growing startup launched by serial entrepreneurs and run by a team gathered from the publishing and tech industries. Millions of readers use our products every day to find great books, and our service empowers thousands of leading publishers and authors to drive sales and find new fans. We’re expanding our team to address the challenges and opportunities of the publishing industry while continuing to help readers find stories and authors they’ll love. Check out BookBub and our audiobooks retailing platform, Chirp, and learn more about what to expect working at BookBub.

Our engineering philosophy

We organize into small cross-functional teams that are deeply focused on one product or initiative. These teams are empowered to make product and technology decisions and quickly build the best solutions for our readers, publishers and authors. Our typical teams consist of four to five engineers, a product manager, and a designer. We lean heavily on automation, good test coverage, and continuous deployment to ensure we’re constantly getting rapid feedback from our users, and follow the approach of starting small, shipping often, and deferring unnecessary complexity. Our teams are strongest when we aren’t over-specialized or operating in separate silos, so we encourage our engineers to rotate teams about once per year.

We believe that we build better products when our teammates have a variety of perspectives and experiences, so we care a lot about creating a supportive and inclusive environment; it’s important that everybody who joins BookBub cares about this, too.

In your first six months, you’ll likely:

  • Work on our mobile listening app for Chirp, contributing to key features like our listening experience and book download management
  • Learn our mobile stack, which spans Kotlin, Swift, and React Native
  • Contribute to developing best practices for developing a React Native app with a significant native-code footprint
  • Work closely with other engineers and colleagues across teams like product, analytics, and design to develop ideas and execute on projects
  • Spend most of your time with your hands on the keyboard, writing code!
  • Pick up other projects or skills based on your interests – whether that’s engaging in more in depth project planning, contributing to our team wide lunch-and-learns, or mentoring other engineers

We’re looking for engineers who:

  • Are smart, friendly, collaborative, and intellectually curious
  • Love to learn and teach, to be both mentors and mentees
  • Possess good judgment on making technical tradeoffs, with a strong bias towards simple and pragmatic solutions
  • Are sensitive to the needs and perspectives of others and care about creating a positive and inclusive environment
  • Enjoy moving products forward quickly, but want to work at a sustainable pace—we're building a business with long-term value
  • Have in-depth experience building and distributing iOS and/or Android apps, and testing them along the way


We offer competitive benefit options including medical, dental, vision, 401k, generous paid parental leave, and take-what-you-need paid time off. We encourage everyone to take at least four weeks a year off, in addition to our thirteen company holidays. Rest and rejuvenation is a key part of sustainable work, and we want all of our employees to find a balance that works for them. 

$140,000–$240,000 is the anticipated salary range for this role. Ultimately, the offer will be aligned with skills and experience, and will be adjusted within or around this range based on the candidate who joins the team.

Our team has choose-where-you-work flexibility that allows you to choose a predominantly remote, hybrid, or in-office setup at our Cambridge, Massachusetts office. We’ll help each team member figure out the work set up that’s best for them, including WFH equipment or a dedicated desk space in our office. We value the health and safety of our people above all else, and our in-person work options will remain contingent on local safety guidelines and recommendations.

Most of our teams currently operate with a hybrid model, with some people working full- or part-time from the office, and some from home. We value and prioritize collaboration across mediums and spaces, and we invest in ensuring that meetings and other forms of collaboration are set up with equal access regardless of where you work.
