Job description

We're looking for a Staff Software Engineer to help build the next generation of our monetization platform as we evolve toward a consumption-based business model.

This is a highly strategic, founding-style opportunity within a newly formed team focused on usage metering, billing infrastructure, entitlements, and revenue systems. You will help define the architecture and technical direction for how product usage is measured, billed, and integrated across finance and operational systems.

You'll partner closely with Engineering, Product, Finance, and Pricing leadership to design reliable systems that directly impact company growth and revenue.

If you're excited about solving complex billing and monetization challenges at scale, we'd love to talk.

What You'll Do

• Design and build scalable usage-based billing and metering infrastructure.
• Define and implement event-driven architectures that power revenue-critical systems.
• Ensure accurate, reliable collection and processing of billable usage events.
• Build and evolve integration layers between product systems, billing platforms, and finance systems.
• Develop entitlement and access management capabilities tied to plans, subscriptions, and consumption.
• Create self-service customer experiences for usage visibility, credits, upgrades, and purchases.
• Partner with Finance and Pricing teams to translate business requirements into scalable technical solutions.
• Evaluate and integrate third-party billing, metering, and monetization platforms.
• Drive architecture decisions and establish best practices for reliability, observability, and scalability.
• Mentor engineers and provide technical leadership across multiple teams.

What We're Looking For

Required Qualifications

• 8+ years of professional software engineering experience.
• Expertise with Node.js and TypeScript.
• Strong relational database experience, including query optimization and performance tuning.
• Experience designing and operating event-driven architectures.
• Experience building highly reliable systems where data accuracy and consistency are critical.
• Ability to lead technical initiatives across multiple teams and stakeholders.

Preferred Qualifications

• Experience building usage-based, consumption-based, or transaction-based billing systems.
• Experience with metering, rating, invoicing, or revenue-related platforms.
• Experience building customer-facing self-service billing or subscription management capabilities.
• Experience integrating with finance, ERP, CRM, or payment systems.
• Familiarity with entitlement management and product access controls.
• Experience working in SaaS, developer platforms, FinTech, cloud infrastructure, data platforms, or AI products.
• Experience supporting AI-driven or agent-based consumption models.

Ideal Background

We are particularly interested in candidates who have experience with:

• Consumption-based pricing models
• Usage metering systems
• Subscription management
• Payments platforms
• Financial system integrations
• Credit or token-based billing models
• Entitlement and provisioning platforms

Success in This Role

In your first 6-12 months, you will:

• Help establish the foundation of our modern monetization platform.
• Improve the accuracy and reliability of usage tracking and billing systems.
• Build scalable integrations that connect product usage to billing and finance operations.
• Partner with stakeholders across engineering, product, pricing, and finance to support new monetization strategies.
• Influence the long-term architecture and direction of a critical company initiative.

Why Join

• Opportunity to tackle challenging, business-critical engineering problems.
• High degree of ownership and autonomy.
• Foundational role within a newly formed team.
• Significant influence on product and platform strategy.
• Exposure to engineering, product, pricing, finance, and executive leadership.
• Opportunity to shape how a rapidly growing platform monetizes future products and AI capabilities.

If you enjoy building systems where reliability, scale, and business impact matter, we'd love to hear from you.
