Position Overview

Software Engineer II joining our US engineering team to help design and build large-scale data pipelines and the platforms and services built on top of them. You'll own features end-to-end—from design through production support—on systems that process hundreds of millions to billions of records against fixed delivery schedules. The work spans new services and long-lived systems, combining cloud-native infrastructure with third-party and on-premises integrations.

Key Responsibilities

• Design, develop, test, and deploy features across our data pipelines and platform services, owning them through to production.
• Implement distributed data processing jobs, along with the orchestration and configuration that drive them.
• Build services and APIs that expose pipeline data and platform capabilities to internal teams and clients.
• Integrate external systems—including data vendors, client delivery endpoints, cloud warehouses, and third-party software—and make those integrations observable and recoverable when they fail.
• Add instrumentation, alerting, and automated tests so problems surface before reaching a client.
• Contribute to infrastructure-as-code and CI/CD pipelines.
• Participate in code reviews, incident response, and knowledge sharing across the team.
