Senior Enterprise Applications Developer (NetSuite)

Overview:

We are looking for a Senior NetSuite Developer to join the Enterprise Applications team within IT Information Systems. You will design, build and support custom solutions on the Oracle NetSuite platform using SuiteScript 2.x, SuiteFlow and the SuiteCloud Development Framework, and own the integrations that connect NetSuite to the wider application landscape. Working closely with Finance, Accounting and operational teams, you will turn complex business requirements into scalable, well-governed solutions. As a senior member of the team, you will also act as a technical lead and mentor, setting development standards and helping shape the long-term roadmap for our ERP platform.

What you will do:

Design, develop, test and deploy NetSuite customisations using SuiteScript 2.x (User Event, Client, Scheduled, Map/Reduce, Suitelet and RESTlet scripts), SuiteFlow workflows, custom records, fields and forms.

Partner with Finance, Accounting, Sales Operations and other business stakeholders to gather requirements and translate them into scalable technical designs and solution documentation.

Build and maintain integrations between NetSuite and third-party systems (e.g. CRM, billing, banking, payroll and data platforms) using SuiteTalk REST/SOAP web services, RESTlets and integration middleware, with robust error handling and monitoring.

Build saved searches, SuiteQL queries, SuiteAnalytics workbooks, dashboards and Advanced PDF/HTML templates to meet business reporting and document needs.

Own the development lifecycle for NetSuite changes using the SuiteCloud Development Framework (SDF), Git source control, peer code reviews and sandbox-to-production release management.

Ensure every change follows change-management and SOX/audit controls, including segregation of duties, role and permission design, and complete technical documentation.

Provide Tier 3 support for production issues, carrying out root-cause analysis and resolving defects quickly, especially during month-end and quarter-end close.

Monitor and optimise script performance and governance usage, and assess the impact of NetSuite’s twice-yearly releases on existing customisations.

Support data migrations, CSV imports and data-quality remediation as part of system enhancements and new implementations.

Mentor other developers, define coding standards and best practices, and keep up to date with NetSuite and SuiteCloud platform capabilities to recommend improvements.
