Job Description

At Ernesta, our mission is to bring gorgeous, design-focused custom rugs to homes and places of gathering through a frictionless, transparent, and affordable experience. At the same price as a store-bought, standard-sized rug, a custom-cut rug from Ernesta is not only a better fit, but it will be higher quality and a better buying experience.

We believe that high-quality, custom design shouldn’t be out of reach for consumers, and are working to expand a multi-billion dollar global industry in order to reach this goal.

Driven by our collective mission, our team is humble, smart, sincere, and scrappy. We’re a strong team of problem solvers, innovators, and executors, relentlessly focused on creating and delivering beautiful and delightfully simple and seamless solutions and experiences for our customers. Together, we are excited by the potential to change the global design landscape as we know it.

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.

As a Senior Backend Engineer, you will be a foundational member of the engineering team building Ernesta’s in-house order management system from the ground up. You will own the backend architecture for transactional systems that manage order lifecycles, fulfillment workflows, inventory, and integrations with Shopify, Salesforce, and third-party logistics providers. You will be designing and building the core systems that run the business.

What You’ll Do:

• 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 Include:

• 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
