Core API Developer (full-time)

Notificare is a leading Customer Engagement Platform that helps brands to (re)engage their audience, shed light on customer behavior, and increase conversions. To accommodate our growing business, we are expanding our team.
At the heart of our platform lies our Core API, which is responsible for gathering data and events from both end-users as well as integrations with clients’ back office systems. It takes care of the distribution, processing and storage of that data and allows it to be displayed on clients’ Dashboards to be analyzed and maintained.
We need to make sure our systems are always available, regardless of actual load, are updatable at any time without disturbing normal operations, and, most importantly, we need to be able to align them with the actual business requirements at hand. This means our Core API needs to be built for performance and resilience. Needless to say, our clients trust us to take care of their valuable and sensitive user data, so security is at the heart of everything.
In other words, we are looking for a backend developer that will help us scale to the next level.

Notificare can hire candidates in the Netherlands and Portugal where we have a legal entity, assuming you have eligible working rights. As our offices re-open, Notificaristas can choose to work remotely or return to an office, unless it’s necessary for the role to be performed in the office. Interviews and onboarding are conducted virtually, a part of being a remote-first company.
