The Challenge

As a business, PushOwl constantly faces the tradeoff with regards to building features quickly to achieve immediate returns versus building these features in a scalable fashion. The market environment (Shopify, e-commerce marketing, web push notifications) is very positive and allows for quick wins in regards to increasing revenue quickly by building additional features for our existing and future client base. However, understanding the (potential) volume of notifications that our clients are sending, we need to keep system performance in mind for scenarios where usage goes 10x and 100x. We are seeking an engineer who can embrace this tradeoff and is ready to make difficult decisions in order to accelerate business growth without venturing it unnecessarily.
