Senior Software Engineer, NetSuite Integrations

Senior Software Engineer, NetSuite Integrations Location: Remote / Hybrid, Canada / US Level: Senior (L5-L6) Reports to: Senior Director of Engineering, Platform & Infrastructure Team: Data & Integrations Why you'll love this Nue.io opportunity! We're looking for a highly motivated Senior Software Engineer to own and evolve the Nue-NetSuite integration, one of the most strategically important integrations in our platform. This is not a configuration-only role. You'll be building, scaling, and evolving a production integration that keeps our billing/CPQ layer in sync with our customers' ERP and accounting systems, serving enterprise customers with complex financial workflows. Nue's NetSuite integration orchestrates customer & product syncs, orders, invoices, credit memos, payments and more between Nue and NetSuite. The integration is live with enterprise customers and growing fast. You'll have a mandate to increase reliability, throughput, and self-service capability while extending the integration’s feature set for complex & diverse use cases. If you're passionate about building bulletproof integrations in the financial domain and want to have an outsized impact on a small, high-ownership team, this is the role for you. Responsibilities Own the Nue-NetSuite integration end-to-end. You are the engineering point of contact for NetSuite architecture decisions, integration evolution, troubleshooting & customer escalations alongside the Data & Integrations tech lead. Evolve the integration architecture. Drive improvements to how integration logic is built, tested, and deployed. Ensure proper CI/CD, automated test coverage, and version control across the integration stack. Ensure data traceability and integrity across sync operations, maintaining accurate ID mapping between Nue and NetSuite objects and ensuring auditability of all synced records. Improve customer onboarding and self-service. Build structured configuration models and tooling so that implementation partners and CS teams can set up and manage NetSuite integrations with minimal engineering involvement. Extend integration capabilities based on customer demand, including areas such as bidirectional field sync, multi-subsidiary support, advanced invoice mapping, and revenue recognition. Manage the NetSuite authentication lifecycle , including OAuth 2.0 M2M setup, certificate generation, and token management. Own reliability and error handling. Build and maintain robust retry logic, alerting, and monitoring so that sync failures are surfaced, diagnosable, and recoverable without engineering escalation. Collaborate with implementation partners and customer success teams to resolve integration issues, contribute to runbooks, and ensure documentation is accurate and complete. Leverage AI-powered tooling to accelerate development, testing, debugging, and operational workflows across the integration stack. What We're Looking For 5+ years building and scaling backend systems in production SaaS environments. Strong proficiency in Java/Spring Boot , with experience building RESTful services, data pipelines, and integration middleware. Deep understanding of NetSuite as a platform: REST/SOAP APIs, SuiteQL, SuiteScript, record types (Customers, Items, Sales Orders, Invoices, Credit Memos, Customer Payments), custom fields, subsidiaries, and authentication (OAuth 2.0 M2M, Token-Based Auth). Experience building or maintaining ERP integrations (NetSuite, Intacct, QuickBooks, Dynamics, or similar), including field mapping, data coercion, error handling, and retry logic. Solid SQL expertise, with experience in query optimization, schema design, and transactional integrity. Experience with API design and integration patterns : REST, GraphQL, webhooks, event-driven architectures, and iPaaS platforms (Tray.io, Workato, MuleSoft, or similar). Excellent collaboration and communication skills. Able to partner with product, customer success, implementation partners, and external customers. Comfort working in a fast-paced startup environment with a small, high-ownership team where you are expected to own problems end-to-end. Demonstrated ability to leverage AI-assisted development tools (e.g., Claude Code, GitHub Copilot, Cursor) to accelerate engineering workflows. Bachelor's degree in Computer Science, Engineering, or equivalent practical experience. Preferred Skills Direct experience with NetSuite SuiteCloud Platform : SuiteScript 2.x, SuiteBundler, RESTlets, Saved Searches, and custom record types. Experience with complex NetSuite configurations including multi-subsidiary and multi-currency. Domain knowledge in revenue operations, billing, order-to-cash (O2C), or financial systems . Salesforce platform development and integration experience. Familiarity with data warehousing tools (Snowflake, Sigma) and how ERP data feeds downstream analytics. AWS services (RDS, Lambda, SQS). Experience with SOC 2, GDPR , or other compliance frameworks as they relate to financial data integration. GitLab CI/CD pipeline experience. What Success Looks Like You are a trusted owner of the integration. You can independently own production escalations, debug sync issues, and ship features end-to-end. The integration architecture is improving. Integration logic is progressively moving toward better testability, CI/CD coverage, and version control. Each component you touch gets more robust. Enterprise-scale throughput is supported. High-volume customers can rely on our integrations for thousands of daily transactions without hitting reliability or performance limits. Customer onboarding is repeatable and partner-led. Implementation partners can configure and activate a NetSuite integration using documented runbooks and self-service tooling, with minimal engineering involvement. Integration reliability is proactively managed. Monitoring, alerting, and retry infrastructure catches and surfaces issues before customers report them. Failed syncs are diagnosable and recoverable without engineering escalation. Product gaps are closing. High-demand capabilities are shipped steadily, reducing customer escalations and unblocking new deals. AI is embedded in your workflow. AI-powered tooling is actively used for development, testing, debugging, and operational tasks, not as an afterthought, but as a force multiplier. What We Offer Competitive salary and benefits package. Opportunity to join a high-growth company with significant upside potential. High ownership, high impact. You'll be a critical hire addressing one of the top engineering priorities. A collaborative and supportive team environment that encourages personal and professional growth. Flexible remote/hybrid work arrangement within Canada. The chance to work on challenging integration problems at a company scaling rapidly in the revenue lifecycle space.
