Impact of a Billing Systems Architect

As an Enterprise Billing Systems Architect at Upsun, you are the technical anchor of our billing infrastructure, playing a vital role in ensuring our revenue operations, pricing structures, and financial integrations run seamlessly as our business scales. Picking up primary ownership from our implementation partner, you serve as the dedicated technical lead bridging Finance, Product, and Engineering.

You’re deeply analytical, systems-minded, and collaborative—someone who thrives on translating complex business, pricing, and accounting rules into reliable system logic. Working downstream from our core engineering and data mediation teams, you ensure the integrity of our Quote-to-Cash (Q2C) platform while continuously optimizing platform performance and automation.

Beyond day-to-day platform administration, you contribute to the long-term evolution of our billing architecture—supporting new pricing model launches, complex usage rating schemes, and financial system integrations. Your attention to detail, technical versatility, and cross-functional mindset ensure our revenue pipeline remains scalable, compliant, and friction-free.

What to expect

• Billing Infrastructure & Administration: Serve as the hands-on technical owner of our BillingPlatform environment, configuring catalogs, price cards, usage rating rules, and automated invoice schedules.

• System Operations & Maintenance: Own ongoing platform health, including system updates, pricing launches, recurring bill-run troubleshooting, sync exception handling, and root-cause issue resolution.

• Data Ingestion & Analysis: Utilize SQL to perform data validation, rating engine auditing, and operational reporting while collaborating with Engineering to receive mediated usage data (e.g., via DigitalRoute or Kafka).

• Integrations & API Management: Maintain and optimize clean, API-driven integrations connecting BillingPlatform to upstream CRMs (e.g. Salesforce), downstream ERP/GL tools (e.g., NetSuite), and payment gateways (e.g., Stripe).

• Revenue Recognition Alignment: Partner closely with Accounting to ensure system rating rules, revenue schedules, and general ledger mappings satisfy ASC 606 and IFRS 15 compliance standards.

• Cross-Functional Collaboration: Gather technical and operational requirements directly from Accounting, Finance, Sales Ops, and Product teams, translating their vision into sustainable platform configuration.

• Data Integrity & Migration: Maintain billing data continuity and manage subscription data updates or migrations without disrupting ongoing financial operations or revenue recognition flows.

What you bring

• Q2C Platform Experience: Proven hands-on experience configuring and administering enterprise Quote-to-Cash or billing platforms (e.g., Zuora, Salesforce Revenue Cloud/CPQ, NetSuite Billing, Aria Systems, or BillingPlatform).

• Data & Technical Skills: Strong proficiency with SQL for querying and auditing billing data, alongside a solid grasp of REST APIs, webhooks, and ETL workflows.

• Modern Pricing Expertise: Experience supporting complex SaaS or infrastructure pricing models—such as PLG, hybrid commitment-plus-usage, tiered rates, and consumption-based/metered billing.

• Revenue Recognition Knowledge: Practical understanding of rev rec fundamentals (ASC 606 / IFRS 15) and how accounting rules dictate billing engine design.

• Cross-Functional Communication: Ability to bridge technical language and financial business logic, effectively collaborating with engineering teams and accounting stakeholders alike.

• Problem Solving & Troubleshooting: A methodical approach to diagnosing system sync errors, rating anomalies, and integration edge cases to ensure operational continuity.

Bonus points

• Experience with DigitalRoute mediation software or Kafka event-stream data intake

• Previous exposure to cloud infrastructure, PaaS, or developer-platform usage metrics

• Background supporting system migrations from implementation partners into internal teams
