About the Role

The Integrations team is at the heart of this mission, powering seamless data exchange between Choco and wholesalers’ ERP systems. We’re looking for a Senior Backend Engineer who thrives on solving complex integration challenges, designing robust APIs, and architecting distributed systems at scale.

What You’ll Do

• Design, build, and scale backend systems and Public API endpoints that enable seamless data exchange between Choco and external ERP systems.

• Develop and maintain integration adapters to ensure reliable data conversion and synchronization of catalogs, orders, pricing, and inventory.

• Architect and optimize scalable solutions and automation to improve integration performance, reliability, and time-to-go-live.

• Collaborate cross-functionally with Solution Engineers and Product teams to troubleshoot integration challenges and deliver smooth customer go-lives.

• Monitor, test, and continuously improve system performance, observability, and developer experience through high-quality documentation and agile delivery.

• Deep understanding of microservices architecture, event-driven systems, and API design principles.

• Proven track record building and maintaining RESTful or GraphQL APIs with a focus on scalability and backward compatibility.

• Hands-on experience with integration patterns, data synchronization, and operating software at scale.

Nice to Have

• Background working with ERP systems, integration platforms, or iPaaS solutions.

• Familiarity with n8n or other workflow automation tools.

• Understanding of e-commerce data models (catalogs, orders, inventory) and public API design.

• Hands-on experience with observability tools (e.g., Datadog, New Relic) and awareness of SOC2 compliance best practices.

• Contributions to open-source projects or developer communities.
