Senior .NET Developer @ Seafar

The ultimate strategic goal from Seafar is ambitious: to scale operations to 1000 vessels by 2030, a significant increase from the current 50. The Senior .NET Developer will join the team at a pivotal time, moving the company from a stable, smaller operation toward this massive scalability and growth. The core purpose of this role is to be the senior technical profile in the team, bringing essential experience and best practices to the table. You will be responsible for shaping the cutting-edge WPF desktop application and the Remote Operation Center, which is one of the most critical, user-facing systems. Your expertise will directly enable the implementation of new features, focusing on key pillars like increasing safety, optimising crew, and scaling operations. 

This is an opportunity to work on high-impact systems where precision, real-time data, and innovation intersect with the physical world, helping to power the next generation of vessel systems and simulations. You are not just writing code, you are directly influencing the future of remote vessel technology by ensuring the highest quality and performance of the solution.

Tasks and responsibilities
Architecture and feature implementation:

• Technical leadership and strategy: Serve as the senior technical profile, introducing architectural experience and best practices to the team. The role requires driving the technical analysis and implementation of critical ROC features.
• Platform development: Architect and develop a modern WPF desktop platform built for superior performance and scale, utilizing the latest in .NET 8.
• Advanced design patterns: Apply Domain-Driven Design (DDD) and adhere to the Reactive Manifesto (using Rx.NET) to ensure the business logic is clean, scalable, and testable.
• Real-time hardware integration: Integrate real-world input hardware (such as joysticks, pedals, and buttons) and telemetry using reactive programming for high-performance interaction.
• Simulations: Contribute to the development of vehicle and joystick simulations that accurately replicate real-world scenarios with millisecond precision, which is vital for safe and scalable operations.

Quality assurance and system infrastructure:

• Core systems project: A significant project involves replacing the existing data communication pipeline in Azure, which is highly critical—a failure would lead to a loss of contact with the vessels. This includes evaluating, testing, and ensuring the development of a redundant, fail-safe alternative.
• Quality standards: Maintain the standard of high quality, requiring a focus on security, performance, and scalability across the entire stack.
• Testing and validation: Write robust unit and integration tests (using MSTest and Moq) to ensure system quality and stability.
• DevOps collaboration: Collaborate closely with DevOps to build reliable CI/CD pipelines and infrastructure automation. System performance must be monitored and fine-tuned using Application Insights.

Mentorship and autonomy:

• Team coaching: Provide daily, informal coaching and mentorship to the three junior developers on the team. This involves leading by example and setting the technical bar for the team.
• Roadmap execution: Execute the roadmap items and drive them technically in close collaboration with the Product Manager.
• Decision-making: The role operates with a high degree of autonomy within the small team. While the Software Engineering Team Leader (Aleksander Chernyavskiy) carries the end responsibility, the Senior Developer is expected to drive technical decisions and take ownership of critical systems.

Projects
Individual login feature:
Currently, all captains log in under one generic username and password, allowing anyone to sail under the same name. A new project, starting at the end of 2025, is the implementation of an individual login system. This feature touches all domains of the system and is a key step in enhancing security and accountability.
Data communication pipeline replacement:
The team is dissatisfied with the current data communication model in Azure and intends to change or replace it. This project is highly important because if this pipeline breaks, they lose all contact with the vessels. The developer will be tasked with finding a robust alternative, testing it, and ensuring there is a proper fail-safe protocol in place.
Scaling and safety features:
The company's roadmap is driven by the strategic pillar of scaling operations towards 1000 vessels by 2030, and increasing safety and complying with complex regulations. The ROC application requires innovation and new features, such as those that enhance safety, to move beyond its current state of supporting 50 vessels and to meet regulatory feedback.
