Software Mind is a software engineering partner that builds and scales digital products for companies in the US and Europe. Our LATAM teams work directly with client engineering teams on complex, high-impact projects.
We’re partnering with a leading US promotional products and e-commerce company to build a new shipping and delivery service for its white-label B2B commerce platform. The platform runs on Shopify Plus with a .NET microservices backend on AWS. The new service connects major shipping carriers, the storefront, and the existing order management systems. It’s a short, focused engagement: a discovery phase, then two-week sprints through production release.
What you’ll do:
· Build and own the Shopify storefront integration (Admin API, webhooks, checkout integration points)
· Develop React interfaces, including admin and configuration tools
· Design and implement .NET 8 Web API endpoints and services
· Integrate third-party APIs behind clean adapter layers
· Work with event-driven messaging (SNS/SQS), including idempotent handling and retries
· Keep customer-facing flows fast and resilient
· Align API contracts with the client’s storefront partner
· Write unit, integration, and component tests
· Document APIs (OpenAPI) and integration flows in Confluence
· Take part in code reviews, sprint ceremonies, and technical sessions with the client
Must have:
· 5+ years of full-stack development with strong C# / .NET (ASP.NET Core, .NET 6+) and React (TypeScript)
· Hands-on Shopify integration: Admin API (GraphQL/REST), webhooks, checkout integration
· Solid REST API design with OpenAPI / Swagger
· Third-party API integration: authentication, rate limits, retries, error handling
· Working knowledge of AWS: Lambda, SQS/SNS, ECS
· Clean architecture: dependency injection, DDD/CQRS concepts
· Testing discipline across backend and frontend
· Docker and CI/CD
· Excellent written and spoken English for daily client interaction
Nice to have:
· Shipping or carrier API experience
· Shopify Plus, Hydrogen, or headless commerce storefronts
· Admin UIs built with component libraries (Polaris, MUI, or similar)
· Retail, e-commerce, or promotional products domain knowledge
