Position Summary:

As a Senior Software Engineer II on our Core Billing team, youll be an essential force behind the evolution of Pax8’s billing platform, supporting critical financial functions such as orders, invoice generation, and regional tax requirements. In this role, you will not only contribute to complex software design and development but also lead initiatives that help refine and restructure our systems. You’ll be at the forefront of our journey to modernize and migrate our monolithic invoice architecture into microservices, making an impactful difference in how businesses manage their billing needs efficiently.

In this role, you’ll work at the intersection of backend development and cross-functional collaboration.
