Software Engineer, Monetization Platform

Where multiple locations are listed for this role, the position may be based in any of those locations, with priority determined according to the order of listing.

At Simular, we are building AI agents that operate computers to help people and businesses get work done. As our product reaches more customers, we need the commercial systems that make product access, pricing, and revenue reliable. You will build the backend foundation that turns customer accounts and product usage into clear plans, accurate bills, successful payments, and correctly provisioned access.

This is a SaaS monetization role focused on accounts, subscriptions, billing, payments, and entitlements. It is not an ads monetization role, and it is not primarily a cloud infrastructure or agent-runtime role.

What you'll do

• Own the domain models and APIs for customer accounts, organizations, workspaces, plans, pricing, trials, seats, and entitlements

• Build subscription and usage-based billing systems, including metering, aggregation, invoicing, credits, proration, upgrades, downgrades, cancellations, and recovery flows
