What Is The Role :

Billing powers Elastic's Cloud business. It runs across AWS, GCP, and Azure in over 50 regions. We oversee usage-based metering, consumption billing, and marketplace integrations at global scale.
The Billing Core team owns the data layer that makes billing correct, auditable, and automated. We work across two areas:
  • Usage — Collect and process usage and cost data. This data is the foundation of our billing and financial reporting.
  • Engine — Turn hourly usage data into customer invoices and revenue records.
We are looking for a Principal Software Engineer to drive technical direction within the Billing Core domain. This is a hands-on role. You will design systems, improve how we operate, and work across teams. You will help our billing services grow in scale, reliability, and developer productivity. You will work closely with Product, SRE, and Cloud Infrastructure teams.

What You Will Be Doing :

  • Own complex billing and account management systems that span multiple services and cloud providers.
  • Build large-scale data pipelines for billing data ingestion, transformation, and reconciliation.
  • Improve observability, incident response, and reliability of core billing systems using modern DevOps practices.
  • Shape system architecture for scale and modularity. Guide service design, API structure, and data modelling.
  • Work with SRE and Cloud teams to improve deployment, monitoring, and CI/CD pipelines.
  • Own PostgreSQL data architecture and performance. Focus on query speed, schema quality, and high availability.
  • Be the go-to technical reviewer for the billing core stack. Maintain technical consistency and quality standards.
