Descrição da oferta de emprego

You will architect and build a high-performance Data Service Layer and API-first adapters that seamlessly unify heavy enterprise IT systems and legacy calculation engines into a centralized platform. You will have a direct impact on defining a Canonical Product Data Model and designing a resilient and modern backend.

Your Role and Responsibilities:

• Architect, develop, and maintain decoupled, high-performance microservices and orchestration layers using C# and the .NET / ASP.NET Core ecosystem.
• Implement a robust, high-performance Data Service Layer designed to process intensive mathematical calculations using asynchronous, concurrent, and parallel processing patterns without blocking application flow.
• Build clean data mapping adapters to translate fragmented, legacy enterprise data structures into a unified Canonical Product Data Model.
• Manage asynchronous enterprise data streaming across the platform and downstream data warehouses using message hubs such as Azure Event Hubs or Kafka
• Coordinate native connectivity and enterprise-grade data exchange with heavy background systems, including SAP ERP (ECC, S/4HANA) and Microsoft Dynamics CRM
• Apply strict backend engineering best practices in static typing, clean code, design patterns, automated unit and integration testing, and Domain-Driven Design (DDD)
• Support containerization and cloud-native deployment workflows using Docker and Kubernetes

Your Skills and Experiences:

• Solid, production-proven experience in backend software development using C# and the .NET ecosystem, particularly ASP.NET Core and .NET Web APIs.
• Advanced expertise designing secure, enterprise-grade APIs using RESTful patterns and/or GraphQL.
• Deep understanding of asynchronous programming, concurrency, parallel processing, and multi-threading, with experience optimizing CPU-intensive algorithms and complex calculation workloads.
• Hands-on experience building system-to-system integration adapters, data transformation pipelines, and event-driven architectures.
• Strong practical knowledge of relational databases and document-oriented systems such as MongoDB.
• Familiarity with enterprise IT landscape
• Exposure to SAP ecosystems or heavy-industry calculation pipelines is a major advantage.
• Fluent in English, both spoken and written, with an autonomous and problem-solving mindset.

What you can expect from us:

• Remote-friendly environment;
• Highly attractive salary and benefits;
• Great work-life balance and flexibility;
• You will be part of a company where commitment, quality, and continuous improvement are core principles of our culture;
• Highly engaged tech community;
• International career opportunities;
• Focus on individual development.
