Staff Software Engineer, Alloy Integrations

Who we are

About the team

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 marketplaces (AWS, Azure, and Google Cloud), ERP systems like NetSuite and QuickBooks, and CRM systems like Salesforce. We also bring Stripe products such as Checkout into Metronome, so customers can move from contract to cash in one place.

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
• Quote-to-cash automation: connecting the full journey from a signed deal to recognized revenue

What you'll do

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.

Responsibilities

• 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

Who you are

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.

Minimum requirements

• This is a Staff level role, so we typically target 10+ years of professional experience building and operating backend systems in production
• Experience designing and integrating with third-party APIs, including handling failures, retries, and data consistency across systems
• Experience with distributed or event-driven systems, such as message queues, streams, or workflow engines
• Experience owning services in production, including monitoring, on-call, and incident response
• Ability to communicate technical tradeoffs clearly to engineers and to people outside engineering

Preferred qualifications

• Experience with billing, invoicing, payments, tax, or other financial systems where correctness matters
• Experience with AWS serverless and data services such as Lambda, Kinesis, SQS, or Step Functions
• Familiarity with ERP or CRM platforms such as NetSuite, QuickBooks, or Salesforce, or with cloud marketplace billing
• Experience with GraphQL APIs and relational databases such as Postgres
• Experience leading cross-team projects or large migrations
