Senior NetSuite Developer

We’re looking for a skilled and proactive Senior NetSuite Developer to join our Global Financial Systems team. You'll work alongside another senior developer to deliver scalable, secure, and well-maintained NetSuite solutions — supporting a global finance organization. The role involves a mix of scripting, integration work, and collaboration with stakeholders across the business.

WHAT YOU’LL DO

• Design, build, and maintain custom NetSuite scripts (SuiteScript 2.x), workflows, and configurations.
• Co-own the NetSuite scripting landscape together with another senior developer — including code quality, peer reviews, and documentation.
• Develop and manage integrations between NetSuite and other systems such as Coupa, Workday, and Concur.
• Partner directly with finance teams to translate business requirements into reliable technical solutions.
• Align with architectural and security principles to ensure long-term system stability and scalability.
• Contribute to system documentation and support readiness for newly developed solutions.

WHAT YOU’LL GET

You’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers. Motivated by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, working collectively to tackle the toughest problems in the financial markets.

In addition, you’ll receive:

• A performance-based bonus structure unmatched anywhere in the industry. We combine our profits across desks, teams and offices into a global profit pool
• The opportunity to work alongside best-in-class professionals from over 50 different countries
• 25 paid vacation days and fully paid first-class commuting expenses
• Training opportunities and discounts on health insurance
• Extensive office perks, including breakfast and lunch, world-class barista coffee, sports and leisure activities, Friday afternoon drinks, and weekly in-house chair massages
• Competitive relocation packages and visa sponsorship where necessary for expats

WHO YOU ARE

• 5+ years of development experience within NetSuite, including strong command of SuiteScript 2.x and SuiteFlow.
• Proven experience developing and maintaining integrations (RESTlets, custom APIs, middleware platforms, etc.).
• Solid understanding of financial processes within ERP systems (e.g. GL, AP, AR, intercompany, tax, procurement).
• Comfortable working in a fast-paced, global environment with multiple systems and stakeholders.
• Able to translate CFO-level problem statements into technical solutions (and vice versa), and explain complex concepts in simple terms to non-technical stakeholders.
• Experience working with Coupa, NSPB/PBCS, Concur, or other EPM platforms is a pre.
• Basic knowledge of Python is a plus, especially for data transformations or automation tasks.
• Understanding of financial system controls and audit considerations.
