Staff Software Engineer, Alloy Integrations

In this role, you'd be joining the Alloy Integrations team. We own how Metronome's customers collect payments and recognize revenue. We build and run the integrations that connect Metronome's usage-based billing platform to the systems businesses depend on to get paid: Stripe invoicing and payments, cloud marketplac...

Our team helps Stripe increase the GDP of the internet by making sure every invoice reaches the right system and every payment is collected and accounted for correctly, at scale. We focus on two areas:

Invoicing: collection, dunning, and invoice delivery

You'll build and operate distributed systems that move billing data between Metronome and the platforms our customers use to run their finances. The work combines product engineering and reliability. You'll ship features that customers ask for directly, and you'll strengthen the event-driven pipelines that handle large invoicing spikes every month-end.
You'll work closely with our product manager, with partner engineering teams that own contracts, usage rating, and invoice finalization, with solutions architects who build ERP integrations with customers, and with technical support engineers who work with customers every day. In your first few months, you'll ship a customer-facing improvement to one of our integrations, join the on-call rotation, and take ownership of one of our core systems.
Design, build, and maintain integrations between Metronome and external billing, payments, marketplace, ERP, and CRM platforms
Build reliable, event-driven systems for invoice delivery, payment workflows, and status sync, with safe retries, rollbacks, and reconciliation
Ship features that help customers control how they invoice, collect, and account for revenue, from design through launch
Improve observability and automated repair across our systems so problems are caught and fixed before customers notice them
Participate in an on-call rotation and lead incident response, root-cause analysis, and follow-up work for the systems the team owns
Plan and carry out migrations and changes to existing integrations without disrupting customer billing
Partner with product, support, solutions architecture, and other engineering teams to scope work and represent customer needs

We're looking for someone who meets the minimum requirements to be considered for the role. If you meet these requirements, you are encouraged to apply. The preferred qualifications are a bonus, not a requirement.

Experience with billing, invoicing, payments, tax, or other financial systems where correctness matters

Familiarity with ERP or CRM platforms such as NetSuite, QuickBooks, or Salesforce, or with cloud marketplace billing
