Role Snapshot

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.

What You'll Do

Design, build, and maintain custom web-based Java enterprise applications, with primary responsibility for backend logic and core business algorithms

Develop and optimize Microsoft SQL stored procedures that support complex billing calculations and high-volume data processing

Translate business rules, billing contracts, and operational needs into clean, reliable system logic

Own enhancements, maintenance, and controlled changes to internally developed and vendor-supported applications

Collaborate with Accounting, Billing, and IT partners to ensure applications align with business and regulatory requirements

Participate in application architecture discussions and contribute to long-term system improvement efforts

Perform hands-on coding, testing, debugging, and production support

Support User Acceptance Testing (UAT) and quality assurance efforts to ensure reliable releases

Troubleshoot production issues, investigate root causes, and implement durable solutions

Maintain code and documentation using GitHub and established development standards

Use AI-assisted development tools (e.g., Copilot, ChatGPT, Claude) thoughtfully to support development, testing, and analysis

What You Bring

A solid software development foundation with growing senior-level judgment

Interest in long-term system ownership rather than short-term consulting or product churn

Comfort working closely with business partners and explaining technical concepts clearly

A steady, detail-oriented approach to building reliable enterprise systems

Ability to manage multiple priorities while contributing consistently to team goals

Education & Experience

Bachelor's degree in Computer Science, Business, Information Technology, or a related field

Typically 5-8 years of experience in software development, systems analysis, or enterprise application support

Experience working in transactional, data-driven, or regulated system environments

Exposure to leading small initiatives, system enhancements, or functional areas preferred

Equivalent education and experience combinations will be considered

Skills & Knowledge

Working proficiency in Java or another object-oriented programming language (Java preferred)

Strong experience developing and maintaining MS SQL stored procedures and working with relational databases

Familiarity with web technologies such as JavaScript, HTML, CSS, and related frameworks

Understanding of basic application architecture, system design, and data modeling concepts

Experience following structured development, testing, and QA practices

Familiarity with GitHub and collaborative development workflows

Ability to work effectively in a stable enterprise environment where systems evolve thoughtfully

Exposure to billing systems, accounting concepts, or the electric utility industry is a plus, but not required
