Middle Financial Systems Engineer

About This Role

What You'll Do

• Serve as the technical owner of Celigo, building and maintaining the integrations that connect NetSuite to Stripe, Salesforce, Bill.com, ADP, and Ramp.
• Own the Stripe to Celigo to NetSuite billing flow supporting our self-serve product, from build through production support.
• Write and maintain SuiteScript, including scheduled scripts, map and reduce scripts, workflows, custom records, custom fields, and saved searches.
• Build error handling, alerting, and automated reconciliation checks so integration failures surface before they reach close rather than during it.
• Automate manual processes currently performed by the Billing and AR teams, and be able to show the before and after.
• Configure NetSuite to support billing, invoicing, dispute resolution, and cash collection, including fields, forms, workflows, reports, and dashboards.
• Develop and maintain integrations to customer payment portals such as Coupa, Yardi RentCafe, and AvidXchange.
• Support sales tax automation tooling and keep tax logic consistent across billing systems.
• Support finance system configuration in partnership with Accounting across systems such as Bill.com, Ramp, Expensify, FloQast, Egencia and ADP, and alongside the Celigo integrations that connect them.
• Own the Jira intake queue for finance systems issues and automate recurring causes rather than absorbing them as workload. Manage vendor support cases through to resolution.
• Manage sandbox provisioning, environment configuration, credentials, and deployment discipline across environments.
• Support the Company’s external audit to drive timely and accurate delivery of requests to ensure overall success of the audit and ability to meet committed deadlines. 

What You Bring

• 3 to 5 years in finance or business systems, including at least 3 years hands-on with NetSuite beyond administration.
• Demonstrated experience building custom flows in Celigo integrator.io or a comparable iPaaS.
• SuiteScript and JavaScript proficiency, with the judgment to know when a problem belongs in script versus in the integration layer.
• Working experience with REST and SOAP APIs, JSON, and file-based data transfer.
• Accounting literacy sufficient to translate a request from Finance or Accounting into a system configuration: debits and credits, subledger to GL flow, quote-to-cash, revenue recognition mechanics, and the close cadence. You do not need to perform the accounting. You need to understand what is being asked and why.
• A track record of replacing a manual process with an automated one, and the ability to describe what changed and how you validated it.
• Strong written communication, particularly documenting how an integration works and why it was built that way.
• Comfort using AI tools to move faster on scripting and testing, while still owning the judgment for what is correct and production ready.
• Demonstrated experience using AI tools to build something, not just use them. For example a dashboard, internal tool, or process built with Claude or a similar tool.

Nice to Have

• Salesforce to NetSuite integration experience.
• Stripe or comparable payments platform experience.
• SaaS subscription and usage-based billing models, or outcome-based and other high-volume transactional billing models.
• Sales tax automation tooling such as Anrok or Avalara.
• Experience replacing or restructuring legacy integrations while keeping the business running.
• Bachelor's degree in Accounting, Finance, MIS, or equivalent practical experience. 

Why This Role

• Full technical ownership of the integration layer feeding Apartment List's finance systems.
• A clearly scoped remit. You own the systems, not the close, which means your work is building rather than reconciling.
• Space to use AI development tools such as Claude to build, test and document faster.
• Work alongside a small, high-performing Revenue and Billing Operations team with direct access to the people whose work you are automating.
