Role Description We are seeking a sophisticated Engineering Manager to lead the evolution of our Trader product suite. You will be the anchor for our Belfast site, inheriting a team of 9 and leading recruitment of engineers when needed. You will drive a high-stakes technical pivot: migrating our core systems from a legacy Windows/WPF foundation to a modern, cloud-native architecture running on Ubuntu (Linux) with a Blazor frontend.

* Global Integration: Act as a key bridge between Belfast and our teams in Sweden, France, and New York, ensuring consistent API contracts and architectural alignment across time zones.
* Real-Time Systems: Maintain and optimize mission-critical Headless components, ensuring robust data distribution via WebSockets and REST APIs for Tier-1 global Partners.
Required Qualifications
* Education: Bachelor or Master Degree in Computer Science or engineering field
* Experience: 2+ years as an Engineering Manager and 4+ years as a Tech Lead
* The .NET Stack: Expert-level C# and .NET (6/7/8). Must have experience deploying and managing workloads on Linux/Ubuntu.
* API & Real-Time Mastery: Strong proficiency in designing and scaling REST APIs and WebSockets for high-concurrency systems.
* UI Transition: Proven experience (or deep architectural oversight) in migrating from WPF to Blazor.
* AI Proficiency: Practical experience using AI tools to generate production-grade code, unit tests, and documentation.
