Job description

About Posh

We are all social creatures, but the dominant “social” companies today have evolved into digital loneliness machines, driving isolation, anxiety, and mental health challenges around the world.

Human connection is lost. Posh is a beacon guiding us back.

Posh enables anyone to build an IRL community based on shared interests, while connecting consumers with the communities of people just like them. Founded by event organizers who were frustrated with the growing loneliness epidemic and the tools available to build their own event brand, we’ve built the ultimate platform for launching, monetizing, and finding IRL communities of people just like you. In just 6 years, Posh has grown to a team of 70, expanded to 10M+ users, secured $70m in venture funding, and facilitated over $400M in transactions.

At Posh, you’ll drive the technical strategy and shape the experiences that connect millions of people through live events. As a Mobile Engineer, you’ll lead the development of highly-performant, scalable, and delightful user experiences that power our mobile products using React Native and Expo. Your influence will extend beyond coding—you’ll shape mobile architecture, guide product direction, mentor other engineers, and set the standard for mobile excellence across the organization.
This is an in-person position at our New York City office in the heart of SoHo, where you’ll play a pivotal role in revolutionizing how people connect in the real world.
