Back-End Engineer | Go and Node.js

Oscatel is hiring a remote back-end engineer - working with Go and Node.js - to design and implement application layer solutions for a range of projects that underpin mobile telco carriers.

We're building modular scalable solutions around operations and service management for some of Europe's largest and most innovative carriers, all of which we will help you get to grips with.

The domain entails data-intensive services where security, data integrity and uptime are key. This presents lots of interesting design and coding challenges as we build and integrate our technology. We're utilising established IP-based protocols and frameworks, working with the standard Go libraries and Node.js.

You can anticipate a mix of well-defined mainly greenfield projects, along with substantial exploratory work as we validate concepts and build new solutions, maturing these into customisable long-term products.

We offer a culture where you may work under your own initiative as part of a collaborative effort towards common goals. It's an opportunity to be a formative team member, and to grow and improve together.
