About the role

The Ernesta business technology team builds the technology solutions that power the end-to-end business operation of an industry-leading custom rug purchasing experience. This includes a custom-built order management system, manufacturing workflow tools, and delivery management systems. These systems work together to power a self-service-first purchasing experience that exceeds customer expectations before and after their rug purchase.

Responsibilities

• Design, build, and maintain backend services for Ernesta’s custom order management system using Node.js and PostgreSQL
• Own the data model and transactional logic for core business entities: orders, line items, fulfillments, inventory, customers, and product SKUs
• Build and maintain integrations with external systems including Shopify, Salesforce, and third-party logistics and fulfillment providers
• Implement order lifecycle workflows: creation, confirmation, production, fulfillment, shipping, delivery, and returns
• Design RESTful APIs that serve internal tools and connect to the broader e-commerce ecosystem
• Collaborate closely with the Business Systems Product Manager to translate domain model specifications and business rules into reliable, performant backend systems
• Translate product specifications — including entity definitions, state machines, and business rules — into physical database schemas, migration strategies, and API contracts
• Ensure data integrity across systems, defining source-of-truth sync logic and integration contracts between the ERP and external platforms
• Write automated tests and contribute to CI/CD pipelines to maintain code quality and deployment reliability

Qualifications

• 5+ years of backend software engineering experience with strong proficiency in Node.js and relational database such as PostgreSQL
• Experience designing and building transactional data models for systems that manage orders, inventory, fulfillment, or similar operational workflows
• Hands-on experience building and maintaining integrations with external platforms (e.g., external APIs, payment processors)
• Strong understanding of relational database design: normalization, indexing, constraints, and migration strategies
• Experience with event-driven architecture patterns (message queues, webhooks, pub/sub) for system-to-system communication
• Experience building and documenting RESTful APIs
• Familiarity with cloud infrastructure (AWS or GCP), containerization (Docker), and CI/CD tooling
• Ability to work autonomously in a small team environment where you own significant portions of the system end to end
• Domain experience in order management, e-commerce fulfillment, supply chain, or manufacturing systems is strongly preferred
• Strong communication skills to collaborate with product, operations, and business stakeholders
