## Description

We are seeking a skilled Software Engineer to join our Engineering team in San Francisco. The successful candidate will help design and build the next generation of usage-based billing systems that integrate tightly with Stripe and Orb, power real-time usage tracking, and deliver accurate, flexible billing experiences for customers.

* Partner with Finance to automate reporting, reconciliation, and revenue analytics.

Requirements:

* Experience with usage-based billing systems or event-driven architectures.
* Strong Python skills for backend microservices.
* Familiarity with Stripe (payments, invoicing) and Orb (usage metering) APIs.
* Experience with Postgres for transactional data and BigQuery for analytics.
* Experience with Kubernetes and containerized deployments.
* Ability to build admin interfaces or customer dashboards using Next.js.
* Comfort working with event-driven data pipelines (e.g., Kafka, Pub/Sub, or similar).
* Strong cross-functional collaboration skills with Finance, Product, and Data teams.

Nice to Have:

* Experience with FinTech, SaaS, or cloud usage billing at scale.
* Familiarity with cloud providers (AWS, GCP) and their billing models.
* Knowledge of pricing experimentation or monetization platforms.

Compensation:

* $160,000 - $200,000 + equity + comprehensive benefits package
