About JammJar

JammJar is a fast-growing fintech startup focused on transforming the mortgage brokerage industry with AI-powered tools that automate administrative tasks and improve customer interactions. We are building a CRM platform that helps mortgage advisors streamline the mortgage application process, saving time and increasing efficiency. Our vision is to eliminate tedious paperwork and provide real-time, AI-driven insights for brokers, allowing them to better serve their clients.

Role Overview

We are seeking an experienced Backend Engineer (PHP/Laravel) to take responsibility for the backend development of our platform.

You will have the opportunity to shape the backend architecture, help scale our platform as we grow, and play a crucial role in delivering a product that will be used by hundreds of mortgage brokers. We are looking for someone who is a problem-solver, self-motivated, and capable of taking ownership of their work from the ground up.

Proven track record of developing scalable backend services from the ground up.
