Responsibilities:

Specifically, this role will be doing:

• Design and own the end-to-end architecture of a scalable, multi-country, multi-currency billing platform, from capturing billable business events through rating, invoicing and posting to the accounting system
• Define the billing data model – clients, contracts, rate cards, billable events, charges, invoices, credit notes and adjustments – with full traceability from every invoice line back to its source events
• Architect the pipelines that extract billable business events from our supply chain, fulfillment, delivery and SaaS applications into the data platform, guaranteeing completeness and integrity
• Build a flexible rating and pricing engine that supports our commercial models: per-order and per-unit fees, storage, tiered and volume pricing, minimum commitments, subscriptions and pass-through costs
• Ensure the billing platform meets accounting requirements in terms of completeness and timeliness, including revenue recognition, accruals, month-end close, tax across Southeast Asian markets and integration with our ERP
• Design reconciliation and controls: automated checks between operational events, billed charges and financial records, complete audit trails, and processes for disputes, adjustments and re-billing

• Establish and enforce engineering practices: version control and branching strategy, CI/CD, automated testing (unit, integration and data-quality tests), infrastructure-as-code, documentation and observability
• Define data-quality standards and monitoring for billing data, and lead incident response and root-cause analysis when billing issues occur
• Make and document architecture decisions that balance scalability, performance, cost and maintainability on our AWS-based data platform (Amazon Redshift, PostgreSQL)
• Work with revenue operation team to define event contracts and schemas, so that upstream changes do not break billing
• Ensure that settlements from all sources are ingested, monitored, and maintained for maximum reliability
• Translate client contracts and commercial requirements from Finance and the commercial teams into technical specifications, and advise them on the feasibility and billing impact of new pricing models
• Plan and prioritize the billing roadmap with Billing Product Manager; do work break down, effort estimation, and deliver predictably
• Lead, coach and develop the billing engineering team – hiring, setting goals and giving regular feedback – to build a high-performing team
• Protect financial and client data through appropriate access controls, and support internal and external audits
• Identify possible risks and take measures to prevent these and escalate if needed

In order to succeed in this role, we are looking for an individual with the following skill sets and experiences:
