NetSuite Developer (SuiteScript & Celigo Integrations)

About Hairball Hairball is a Certified NetSuite and Celigo Partner focused on automating and integrating business processes for NetSuite-driven eCommerce and product companies. We build connected operations using integration platforms and applied AI, designing how data, systems, and workflows work together so our clients can scale without losing control. As we grow, we’re looking for a NetSuite Developer who can design and build solutions that stand up to real operational complexity. What You’ll Do The NetSuite Developer builds the backbone of our client solutions. You are responsible for designing, developing, and delivering scalable NetSuite customizations and integrations that power real-world operations. You work closely with consultants, integration engineers, and client stakeholders to translate business requirements into clean, maintainable technical solutions. This is not a ticket-taking role — you are expected to think in systems, challenge weak designs, and build solutions that hold up under growth. Key Responsibilities Design and develop NetSuite customizations using SuiteScript (2.x), Suitelets, RESTlets, and SuiteTalk. Build and maintain integrations between NetSuite and eCommerce platforms, 3PLs, WMS, POS systems, and other external applications. Develop and optimize Celigo integrator.io flows and custom integration components. Translate functional requirements into scalable technical architecture. Support core ERP processes including Order-to-Cash, Procure-to-Pay, Inventory, and Financials. Design and implement REST/SOAP-based integrations using JSON, XML, and related protocols. Perform technical testing, troubleshooting, and performance optimization. Document technical designs, integration mappings, and deployment procedures clearly and thoroughly. Collaborate cross-functionally to ensure solutions align with business objectives and delivery standards. Ensure code quality, maintainability, and adherence to Hairball development best practices.
