About The Position

The Application Developer (Enterprise Systems) is an early‑senior, hands‑on software development role focused on building, enhancing, and sustaining OPC's internally developed billing applications. This position is best suited for a developer who enjoys deep ownership of business‑critical systems, close partnership with business users, and working on applications that directly power core operations, not shorter project work. This role sits between senior engineering execution and business systems partnership, offering long-term stability, meaningful ownership, and exposure to complex enterprise systems.
