Sr. Backend Developer - Fully Remote

Sr. Backend (Node) Developer

Fully Remote

Salary range – €60,000 – €90,000 per year

As a senior member of our growing Backend team, you will get to design, build and own a sub-set of the product that will be composed of several high-availability scalable microservices (written in .net core or Node.js).  Fonoa is a technology startup founded in 2018 which launched its SaaS product in mid-2019. We have paying customers, a healthy sales pipeline, and backing from world-class VC funds and business angels from Europe and the US.

Fonoa seats at the intersection of Globalization, Technology and Local tax compliance. Filip and Ivan pinpointed a missing link in a world where global companies are offering local services –  local taxation compliance of transactions. This happens when you order a cab (Uber), order your launch (Ubereats, Grubhub, DoorDush, Wolt) or any other type of purchase that you are making locally via a global provider.

Fonoa’s SaaS automates taxes for platforms, marketplaces, digital service providers, and e-commerce globally. Their software helps service providers to eliminate manual work, reduce the cost of operations and compliance, and optimize their revenue.
