The Billing team is the steward of Core Weave's revenue trust. We build services that make billing auditable, accurate, and clear, so Core Weave can close deals, turn usage into cash, and help customers manage their spend with confidence. This role is on the Billing Product sub-team, which owns customer-facing surfaces, including console dashboards, exports, and APIs, as well as the backend that makes them trustworthy: supply and demand matching, revenue recognition verification, and the metering-to-invoicing pipeline.

About the Role:

As a Senior Engineer, you own backend Go services end-to-end. You'll enable Core Weave to capture every dollar, then make that revenue’s lineage complete, drillable, and SOX-compliant. You'll also be a technical leader, raising the bar for a team of engineers and owning money-critical services: SLAs, production hardening, observability, and on-call. Expect hands-on Go, API, and data-model design, and close work with Rev Ops, Accounting, Finance, and  this role, you will:

Own backend Go services end-to-end: demand and capacity matching, fulfillment and delivery verification, the metering-to-invoicing pipeline, and APIs where customers see their usage, costs, and invoices

Ensure audit-grade lineage so every billed dollar traces back to verified usage

Own the design and build of internal services that enable Capacity, Product, and other stakeholder teams to drive efficiency

Raise the reliability bar: set SLAs, harden services, add observability, and mature on-call Drive technical initiatives and mentor engineers as the team grows its Go and production skills

Who You Are :

You've shipped and scaled business critical, financially compliant services

You have drafted and owned SLAs/SLOs, observability tooling, and sustainable on-call

You have a sharp sense for correctness and prioritize accuracy, completeness, and penny-precision.

You design and evolve APIs and data models–versioning, backwards compatibility, dependent team coordination, etc.

Preferred:

Production engineering: infra, metrics, tracing, and running money-critical services

Data engineering: telemetry ingestion, metering pipelines, warehouse/SQL Billing, metering, rating/invoicing, and / or Fin Ops (e.g., FOCUS exports)

You build trustworthy systems, where correctness and clarity come before new features

You've helped a team level up–better reliability, cleaner operations–and you like to mentor

You care about the person spending the money: clear errors, sensible defaults, answers they can find themselves
