Senior .NET Developer

Shape the future of a fast-growing tech pioneer – Senior .NET Developer at Seafar

Join Seafar, a highly innovative and fast-growing company at the forefront of remote vessel operations. We're breaking new ground in maritime technology — and we want you on board.

We're looking for a passionate Senior .NET Developer to help shape our cutting-edge WPF desktop application, interfacing with vehicle gateway services and real-time hardware controls. This is your chance to work on meaningful, real-world tech with impact that reaches beyond the screen.

What you’ll be building

You’ll play a key role in developing a reactive, high-performance desktop platform, using the latest in .NET 8 and distributed cloud services. You’ll also contribute to vehicle and joystick simulations that replicate real-world scenarios with millisecond precision — critical for safe and scalable vessel operations.

What will you do

• Architect and develop a modern WPF desktop platform built for performance and scale

• Integrate real-world input hardware and telemetry using reactive programming

• Apply Domain-Driven Design (DDD) to keep business logic clean, scalable, and testable

• Simulate and validate control systems in a virtual environment that mirrors real-world interactions

• Collaborate closely with DevOps to build reliable CI/CD pipelines and infrastructure automation

• Monitor and fine-tune system performance using Application Insights

• Write robust unit and integration tests (MSTest, Moq) to ensure system quality

Why you will love Seafar

• Cutting-edge tech: We're using the latest tools and frameworks to solve real-time, high-performance challenges

• Meaningful impact: Your code will help power the next generation of vehicle systems and simulations

• Collaborative culture: Work alongside a team of engineers who value clean architecture, continuous learning, and high standards

• Real-world connection: See your software interact with physical hardware in real time

Tech stack you’ll master:

• .NET 8 (C#), WPF, MVVM, and DevExpress for modern desktop UI

• Rx.NET, DDD, and the Reactive Manifesto for responsive, event-driven architecture

• EF Core with Cosmos DB and SQLite for cloud and local persistence

• Azure Service Bus, Redis, Hangfire, and CQRS for scalable messaging

• TCP-based gateway services and hardware integration (joysticks, pedals, buttons)

• Vehicle & joystick simulations for testing in realistic environments

• Digital Twins, Azure Storage, and PowerShell for system modeling and automation

• Application Insights, CI/CD pipelines, and MSTest/Moq for monitoring, deployment, and testing

• Focus on security, performance, and scalability across the stack

At Seafar, you're not just writing code — you're helping shape the future of remote vessel technology. You'll work on high-impact systems where precision, real-time data, and innovation intersect with the physical world. If you're ready to push the boundaries of what's possible with .NET, cloud tech, and real-world hardware, we'd love to meet you.
