Intermediate Backend Engineer - Platform Integrations (Monetization)

Backend Engineer, Platform Integrations (Monetization)

An overview of this role

As a Backend Engineer on the Monetization Platform Integrations team, you'll design, build, and maintain integrations between CustomersDot and Monetization services and GitLab's enterprise applications, including Salesforce, Workato, and Zuora. You'll own robust application programming interface (API) contracts, protect data integrity across systems, and build resilient cross-platform workflows that support how customers buy, provision, and renew GitLab.

Because these integrations move financial and subscription data between systems, you'll maintain a high bar for reliability, observability, and careful rollout. You'll work closely with the monitoring and anomaly detection side of the team so every integration is observable and the team can catch failures early. We're hiring for this role at the Software Engineer and Senior Software Engineer levels.

What you’ll do

• Design, build, and maintain integrations between CustomersDot, Monetization services, and enterprise applications such as Salesforce, Workato, and Zuora.


• Define and evolve representational state transfer (REST) and GraphQL API contracts, including versioning and backward compatibility.


• Build and monitor observable, fault-tolerant integration workflows, tracking failure rates, retry success, and data-integrity incidents.


• Ensure data integrity and consistency across integrated financial and subscription systems.


• Review merge requests from other Monetization engineers and offer clear, constructive feedback.


• Work with Product, Finance, IT, Sales, and Support to translate cross-system needs into reliable integrations.


• Own projects from proposal and discussion through delivery, rollout, and production monitoring.

What you’ll bring

• Professional experience working with Ruby on Rails.


• Experience integrating with third-party or enterprise APIs, including billing, customer relationship management, or automation platforms.


• Strong API design skills, including REST, GraphQL, contracts, versioning, and backward compatibility.


• Familiarity with event-driven patterns such as webhooks and message-based streaming.


• Familiarity with PostgreSQL or similar relational databases and data integrity and governance concepts in production environments.


• Systems thinking and experience owning projects from concept through production, including proposal, execution, and monitoring.


• Ability to communicate clearly about complex technical, architectural, and organizational problems in a remote, largely asynchronous environment.


• Alignment with GitLab's values; familiarity with NATS JetStream or subscription management or billing systems, such as Zuora or Salesforce, is a plus.

About the team

GitLab's Monetization section is a cross-functional group that partners with Sales, Finance, IT, and Support to deliver secure and reliable purchasing, billing, provisioning, and utilization workflows. The Monetization section includes the Purchase, Subscription Lifecycle, Billing Engine, Platform and Infrastructure, Observability, Monitoring, and Integrations, and Compliance teams. This role is on the Monetization Platform Integrations team and reports to the Engineering Manager, Observability, Monitoring, and Integrations. We work asynchronously, with regular planning and retrospectives and a high bar for operational ownership across deployments, incident management, testing, and rollout safety.
