About the Role

We’re looking for a highly capable PHP Software Engineer to help design, build, and evolve our telecom OSS/BSS platform, which provides billing, provisioning, and customer lifecycle management for broadband providers across the U.S.

This is not a basic web dev role—you’ll work on large-scale, high-availability systems, complex data models, and performance-critical workflows that directly impact our clients’ revenue, operations, and customer experience.

If you enjoy solving real-world problems at scale and working with deeply integrated systems, this role will give you meaningful ownership and impact.
