Senior Software Engineer, Monitoring

Overview

Centah is a SaaS company, part of Financeit, that helps home improvement businesses manage lead intake, routing, and conversion through a configurable platform at the center of their operations. After years of building custom solutions for a small number of large clients, we’re now evolving into a scalable, market-wide SaaS platform. You won’t be maintaining a mature product; you’ll be helping shape what it becomes.

We sit in the middle of a complex ecosystem, ingesting, transforming, and routing data between partners, internal workflows, and downstream systems. APIs, third‑party systems, and asynchronous pipelines must behave predictably when the world is messy. Our stack is Ruby on Rails, Ember.js, and Postgre

SQL, mature tools behind a platform that has to stay stable, secure, and quick as we grow.
