Senior Software Engineer

Join our dynamic ZoneBilling team and help shape the future of Zone and Co's award-winning ZoneBilling product on NetSuite! As a Senior Software Engineer, you'll play a key role in building and enhancing SuiteApps that serve thousands of businesses. You'll not only write clean, scalable code—but also help shape internal tools and processes that improve the way our global engineering teams work.

You'll be part of a small, focused team, which means your contributions will have a huge impact—not just on the product, but on the team and company as a whole. We are technologists and love technology but we love our customers even more, so putting our customers front and center in what we build and how we build is in our DNA. This is a hands-on development role with real influence and visibility.

Responsibilities:

• Build, enhance, and scale the ZoneBilling application using SuiteScript, SQL, and modern JavaScript.
• Write clean, maintainable, and well-tested code.
• Leverage our proprietary SDK—built on top of NetSuite and enhanced with TypeScript, linting, automated testing, and documentation generation.
• Design and execute test cases to ensure feature reliability and performance.
• Write and maintain unit tests to validate functionality and prevent regressions.
• Troubleshoot, debug, and resolve bugs in existing functionality.
• Partner with our principal architect, other engineers, product managers, and QA to define and refine features.
• Participate in code reviews and contribute to a culture of learning and improvement.
• Share development best practices and tools across teams.
• Document systems, architecture, and features clearly.
• Stay current with new tools and techniques, and suggest improvements to development processes.

Job Qualifications:

• 5-10 years of professional full-stack software development experience
• Deep business domain knowledge of billing and revenue or a strong interest in learning the domain or experience in Fintech
• Strong proficiency in JavaScript, and/or SuiteScript, along with experience using modern frontend frameworks (we use React), SQL, and REST and SOAP APIs
• Comfortable working in remote, distributed teams using modern development tools—including Git, automated testing, CI/CD pipelines, and a passion for leveraging GenAI tooling to work smarter and more efficiently
• Demonstrable experience with NetSuite SuiteCloud development and related technologies
• Solid understanding of web services (REST, SOAP), data formats (JSON, XML), Object-Oriented Programming, SOLID Principles, and Design Patterns
• Familiarity with HTML/CSS and general web development fundamentals
• Experience with Node.js or Java is a bonus
• Background working with ERP, HRIS, Payroll, Finance, or CRM systems is highly desirable
• Entrepreneurial mindset—proactive, curious, and ready to learn
