About The Role

We are looking for a Senior .NET Developer to take full ownership of building a robust ERP platform that connects and integrates multiple retail systems for our client. You will be the primary engineer on the ground - working directly with the client's stakeholders and collaborating remotely with a broader cross-functional team. From architecture to deployment, you will drive the technical direction independently. This is a high-impact, high-autonomy role where strong engineering fundamentals, Web API expertise, and the ability to navigate complex integration challenges are essential.

What You Will Do

  • Design, build, and maintain scalable .NET Core applications with a focus on clean architecture and high-quality code standards.
  • Develop and integrate Web APIs to connect multiple business systems and third-party service providers.
  • Contribute actively to system architecture and design decisions - proposing solutions, evaluating trade-offs, and driving technical direction.
  • Lead and conduct code reviews and code refactoring to uphold engineering standards across the team.
  • Plan, write, and document unit and integration tests to ensure software reliability.
  • Own the full development lifecycle: from planning and estimation through design, implementation, testing, deployment, and maintenance.
  • Take ownership of technical decisions and drive engineering best practices independently, without reliance on a local team structure.
  • Stay current with new technologies and actively bring relevant improvements into the team's workflow, including AI-assisted development practices.

    • What You Will Bring

  • 5+ years of experience building cloud-based or distributed applications with .NET Core and Microsoft technologies.
    Strong grasp of OOP, SOLID principles, clean/onion/hexagonal architecture, and design patterns; deep understanding of DDD, CQRS, and TDD.
  • Solid experience with Web API development and integration of multiple business systems and third-party APIs.
  • Hands-on experience with .NET Core, ASP.NET Core, MongoDB, and Message Queue systems; proven ability to optimize high-traffic web applications.
  • Sound understanding of .NET service lifetimes/scopes and database performance, including indexing strategies.
  • Experience developing and maintaining microservice architectures.
  • Comfortable working through system design and architecture questions - able to clarify assumptions, analyze trade-offs, and propose concrete solutions.
  • Proficiency with Git and experience in code review and refactoring practices
  • Able to work independently and take full ownership of delivery; comfortable collaborating remotely with client stakeholders and cross-functional teams across different time zones.
  • Practical experience with AI-assisted development tools and workflows (e.g., using AI for code generation, debugging, documentation, or structured development practices).
  • Good English communication skills - able to read technical documentation and collaborate with international stakeholders.
    • Nice-to-Have
  • Experience with Azure cloud services: Azure Functions, Service Bus, Azure SQL, Cosmos DB, Table Storage.
  • Familiarity with Docker and DevOps practices.
  • Knowledge of Kafka or RabbitMQ for event-driven messaging.
  • Basic knowledge of HTML, CSS, and JavaScript.
