About You We're looking for a senior engineer who's experienced with Python and Airflow, has a sharp eye for data and financial accuracy, and is happy to get stuck into a fast-paced environment to work within our Pricing, Costs & Routing (PCR) squad. You'll champion and lead the build of the automation and data pipelines that power pricing, billing, and financial reporting across Telnyx's product portfolio.

The Opportunity Our PCR squad owns the backend systems and pipelines behind pricing, margin reporting, and cost analysis across voice, messaging, wireless, and the rest of Telnyx's product portfolio. You'll work with complex Airflow DAGs, rate deck management, pricing APIs, and CDR/MDR data at scale.

You'll own and develop services and pipelines that finance, sales, and product teams rely on every day to make pricing decisions, reconcile vendor costs, and report on the health of the business. You'll have the opportunity to make a huge impact by automating workflows that are currently manual, building self-healing pipelines, and bringing more rigor to how we manage pricing across a growing product set. You'll be part of a small, focused team where the work you ship is visible and consequential.

• Own and maintain complex Airflow DAGs for pricing automation, margin reporting, and cost analysis.
• Build and manage rate deck pipelines across multiple product lines.
• Develop and maintain pricing APIs and services in Python (async).
• Analyse CDR/MDR data to identify vendor discrepancies and drive refund and reconciliatio
