Company Description
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.
Job Description
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
Qualifications
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
