Principal Engineer

Description

Datarails is growing, and we're looking for a brilliant, independent Back End Developer to join our R&D team!

Datarails is a SaaS B2B solution that tackles one of the biggest challenges in financial departments: the overflowing amount of data that, up until now, was managed by tons of Excel sheets. All those financial reports, forecasts, expenses, analytics? Datarails takes all this data and integrates it into a one, simple, smart report. It consolidates the information, enables the finance professionals to follow it, manage it, and create the ever-needed order within the realm of finances. If this isn't enough, it enables thorough analysis of consolidated data for the creation of business and financial insights. It’s cloud-based, so nothing gets lost, it’s brilliant, so almost every feature can be added.

This is an exciting opportunity to work on cutting-edge technologies and collaborate with a talented team of developers.

What You'll Do

As a Principal Engineer, you’ll act as a hands-on technical leader, working across backend, frontend, infrastructure, and tooling. You’ll help modernize our platform, lead technical initiatives, and participate in the adoption of our AI tools and developer acceleration technologies.
