Experienced .NET Engineer

As part of a well-established proprietary trading firm, their internal tech department has long supported professional traders with custom-built software. This project builds on that foundation to deliver a high-performance, commercial trading solution from the ground up.

Their goal is to create something unique: a trading platform that combines real-time execution capabilities with AI-powered feedback and coaching, built on top of our proven mentorship experience in live trading environments. At its core is a robust back-end architecture and an intelligence layer that actively monitors trading activity, delivering actionable insights and real-time guidance to traders as they operate.

Role Overview:

We’re looking for a mid-level .NET engineer to join their team on a full-time basis. While the core need is backend-focused, they’re also open to full-stack developers who are comfortable working across both backend and frontend layers.

Engagement: 

Full-time (40 hours/week)

Responsibilities:

• Design, develop, and maintain back-end microservices using C# and .NET 9.
• Work with event-driven systems to process and respond to real-time trading data.
• Build and improve microservices that support execution logic, data processing, and trader guidance.
• Collaborate with other engineers, including infrastructure, design, and data teams, to deliver well-integrated features.
• Write clean, testable, and efficient code with attention to performance and reliability.

Requirements:

• 3-5 years of experience with C# and .NET.
• Familiar with event-driven design and high-performance stream data processing.
• Experience with building microservices.
• Experience working with message brokers like Apache Pulsar (ideally), Kafka or RabbitMQ.
• Good working knowledge of SQL databases, ideally PostgreSQL.
• Comfortable working with Docker and containerized applications.
• Experience writing clean, testable, and production-ready code.
• Familiarity with gRPC or REST API design is a plus.
• Familiarity with frontend development (Avalonia UI) is a plus.
• Background in financial systems or real-time trading platforms is a plus.

What they offer:

• Remote-first work environment with a flexible, collaborative team.
• Opportunity to work on an innovative product with modern architecture and real-time performance challenges.
• Full-time, long-term engagement.
• A chance to help shape a commercial product backed by a successful proprietary trading firm.
• Competitive compensation based on experience.
