About the role

Key responsibilities & impact

eCommerce Development. As a member of our development team, you will execute on development requirements outlined in statements of work and technical design documents. Typical work includes building and customizing SuiteCommerce themes and extensions, developing SuiteScript 2.x customizations (User Event, Suitelet, RESTlet, Map/Reduce, Scheduled scripts), and implementing custom checkout, MyAccount, and order management features. On the Shopify side, building stores, custom Apps and integrations.
Integrations. Design and build integrations between NetSuite and third-party systems (payment gateways, tax engines, shipping/freight providers, SSO/identity providers, PunchOut/B2B procurement platforms) using REST APIs, RESTlets, GraphQL and webhooks.
Team Collaboration. Maintaining a high level of communication with clients as well as other team members is critical. Strong professional communication skills, both verbal and written, are necessary. You will participate in code reviews, daily coordination, and knowledge-sharing sessions.
Consulting & Client Awareness. This is a consulting role, successful people in it have the ability to understand and recognize client needs, both short-term and long-term, and to propose solutions rather than just implement tickets.
