Develop native mobile apps (iOS in Swift and/or Android in Kotlin) for creators and their audiences, with a focus on activation and growth.
Build features across mobile to support user activation and conversion.
Iterate on key user flows in the Substack mobile apps, and run A/B tests to improve activation metrics and drive growth.
Collaborate with designers, writers, support staff, and many others. From product concept and research to implementation, experimentation, and measurement, we expect you to own your work and deliver high-quality solutions.
Work directly with customers to solve their problems. The entire company (CEO included) participates in customer support in order to drive empathy for our users and help us build better products.

Requirements

At least 2-8+ years of software engineering experience with both mobile and full stack development.
Experience shipping high-quality native mobile apps (iOS and/or Android) to app stores.
Independent and autonomous. We're too small to micromanage, and expect that every person at the company owns their work and can be a leader.
Hold yourself and others to a high standard when working on production systems.
Take pride in building elegant and delightful product experiences. Substack works best when it gets out of the way so creators can focus on writing and connecting with their readers.
Enjoy collaboration with a diverse group of thinkers while bringing your own unique experience and background to the team.
Believe in Substack's mission to build a better business model for writing.
Have a degree in Computer Science or equivalent industry experience.
Experience at a fast-growing startup or working on a high-performing growth/activation team is not required, but is a plus.
