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 services empower 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.

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 collaborate and share knowledge, so engineers are encouraged to have a broad view of how our systems work and look for opportunities to work with other teams.

Learn more about what to expect in our engineering interviews.

In your first six months, you’ll likely:

  • Build and deliver apps that let Chirp’s users listen to their books and manage their library, with a focus on improving the experience for users with large libraries or flaky network connections
  • Deepen your expertise in Kotlin and Swift as we migrate our React Native UI to a fully-native one
  • Extend our internal tools for managing and monitoring the app release process
  • Brainstorm ideas and rapidly build exciting new features for our listeners
  • Get involved beyond your team, based on your interests — engage in in-depth project planning, give a talk at our engineering-wide lunch-and-learns, or mentor 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 working on a team to build, test, and distribute iOS and/or Android apps


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.

Remote work flexibility

Please note: for this role, we are considering remote candidates who are located in the following states: MA, NY, RI, ME, PA, MD, and IL. Other locations to be reviewed upon request. 

Our team has where-you-work flexibility that allows you to choose a predominantly remote, in-office, or hybrid setup. 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. Meetings and other forms of collaboration are set up with equal access regardless of where you work. 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.
