About the role

Backend engineers at fomo work on a little bit of everything across all areas of the business - from trading infrastructure to social network scaling. Things we’re working on include:

Trade execution and infrastructure

Trade data ingestion and portfolio tracking

Social network trust and safety

Analytics data ingestion and analysis

Infrastructure scaling and optimization

Constantly refining the user experience, tap by tap and trade by trade

Our stack is primarily written in Typescript with some purpose-specific micro-services.

Engineers at fomo aren’t constrained to any specific area - while this is primarily a backend opening, we encourage our backend engineers to contribute to the frontend when it makes sense (and vice-versa).

This role is in-person in NYC. We have a strong in-person culture and just moved into a new spacious office in Soho.
