Why your role matters

You’ll own how business and customer data flows across the organization, with a focus on billing, product, and sales data. Working at the intersection of engineering, finance, and product, you’ll build the foundation that makes data reliable and auditable, removing manual reconciliation, stabilizing migrations, and ensuring billing flows and pricing models behave predictably at scale.

This is a backend engineering role, not a traditional data or ETL setup. Using Go, you’ll build services and APIs that expose billing logic and connect systems like HubSpot and NetSuite, shaping how data moves across the organization in production.

You’ll work on greenfield architecture and database design, defining customer data models, system relationships, and asset structures that determine what customers can buy and how it is invoiced, using SQL where needed for validation and reconciliation. You’ll be part of a team of five developers, working closely with a Business Analyst and owning these flows end to end.

What you’ll be doing

Own data migrations and pipelines: Design and implement ETL flows to move billing, contract, and asset data into target systems with full validation and rollback capability

Model and transform complex data structures: Analyze legacy databases, define transformation logic, and ensure consistent, idempotent data handling

Build scalable backend services in Go: Develop services and abstraction layers that expose billing logic and enforce business rules, while leveraging the right tools (e.g. SQL, Python) for data transformations and migrations

Standardize product and pricing models: Define reusable product and offer structures that work consistently across systems and integrations

Integrate external systems into billing flows: Connect ERP, CRM, payment, and inventory platforms with secure, reliable data exchange and reconciliation

Develop robust APIs and integrations: Build REST and gRPC APIs with strong validation, logging, retry logic, and monitoring

Automate migrations and operational processes: Create tooling, scripts, and runbooks that support repeatable migrations and controlled cutovers

Improve observability and incident response: Implement monitoring, dashboards, and alerting to quickly detect and resolve data or integration issues

Collaborate across teams: Work closely with Finance, Product, and Business Analysts to refine business rules and validate outputs

Mentor and contribute to architecture decisions: Share knowledge, review code, and help shape the long-term billing architecture
