Since 2011, we have accomplished more than 150 projects, helping SMBs and enterprises overcome business challenges with the right technology solutions.
We are currently looking for a Senior.NET Developer to join a project focused on industrial digitalization. The initiative aims to help organizations structure tender documents, manage requirements, and improve collaboration across enterprise systems. The goal is to develop a reliable and scalable connector enhancement by improving bidirectional synchronization, eliminating message loss, and introducing robust queuing and idempotency mechanisms.
Responsibilities
- Implement a reusable synchronization platform with a modular connector approach.
- Develop an independent DAP middleware service with an isolated Polarion connector module.
- Introduce robust queuing mechanisms using PostgreSQL to prevent message loss and support asynchronous processing.
- Implement idempotent message processing and retry strategies to guarantee consistency under failure conditions.
- Improve system resilience using fault-handling patterns (e.g., Polly) and ensure graceful degradation.
- Maintain and extend synchronization logic across ~40 mapped fields.
- Align solution architecture with evolving DAP (Data/Application Platform) middleware strategy.
- Ensure compatibility with Polarion X and cloud-oriented deployment models.
- Optimize performance and scalability of.NET Worker Services handling high-throughput integration workloads.
- Implement structured logging (Serilog) and distributed tracing/monitoring (OpenTelemetry).
- Contribute to secure integration design using JWT/OAuth2 authentication mechanisms.
- Collaborate with AI, backend, and platform teams for seamless integration.
- Develop automated tests (unit + integration).
- Support packaging and deployment processes (MSI installer, Windows Server environments).
- Participate in architecture discussions, code reviews, and continuous improvement initiatives.
Requirements
- 5+ years in.NET/C# development.
- Experience with.NET Worker Services or background services architecture.
- Expertise in building reliable distributed systems (messaging, retries, idempotency).
- Experience with PostgreSQL, including designing queue-based processing patterns.
- Experience with Entity Framework Core and performance tuning.
- Experience implementing resilience patterns (e.g., Polly or equivalent frameworks).
- Familiarity with observability tools (OpenTelemetry) and structured logging frameworks (Serilog).
- Strong understanding of RESTful integrations using HttpClientFactory and hosting services with Kestrel.
- Experience with authentication/authorization standards (OAuth2, JWT).
- Knowledge of dependency injection patterns (Microsoft.Extensions.DependencyInjection).
- Experience working with Windows Server environments and deployment packaging (MSI or similar).
- Testing practices using xUnit, Moq, or similar frameworks.
- Problem-solving skills with a focus on reliability, scalability, and maintainability.
We Offer
- Equipment for work
- Paid vacation (18 business days) and Statutory Holidays
- Paid sick leave (10 business days)
