Job Description

$180000 - $190000
This is a full-time, U.S.-based senior engineering role focused on modernizing an enterprise-grade SaaS platform that powers the financial and operational backbone of large, multi-location field service organizations. The system supports complex billing, accounting, compliance, and data integrations for organizations operating across dozens or hundreds of locations, and runs continuously in production.

What makes this role compelling is the scale and depth of impact. You’ll be responsible for evolving a mission-critical platform without interrupting live enterprise operations, consolidating a diverse technology stack, and enabling faster customer onboarding and deployment. This is a highly technical role for an experienced engineer who enjoys untangling legacy systems, defining modernization strategy, and leading by example in a small, high-leverage team.
