Senior / Mid Level .NET Engineer (Game Integrations)

We are looking for a skilled Mid-Level or Senior .NET Engineer to join our specialized Game Integrations team. In this role, you will be a key player in expanding our gaming ecosystem. The majority of your time will be spent driving innovation within our modern, dedicated .NET 10 games microservice. You will have genuine ownership over this codebase, shaping its architecture and scalability. Additionally, you will help manage and migrate crucial integrations from our .NET 9 monolithic system. This is a fantastic opportunity for an engineer who thrives on taking ownership, loves the challenge of high-throughput systems, and takes pride in writing clean, highly testable code.

Responsibilities

• Own the Codebase: Take architectural and operational ownership of our core .NET 10 games microservice, driving best practices, performance optimizations, and feature delivery.
• Deliver Integrations: Build, maintain, and optimize robust APIs and services that seamlessly integrate third-party games with our internal platform.
• Manage Legacy & Modern Systems: Balance cutting-edge microservices development with the maintenance and gradual decomposition of our existing .NET 10 monolith.
• Champion Quality: Implement rigorous testing strategies (Unit, Integration, and End-to-End) to ensure our systems remain resilient and deterministic.
• Navigate Regulated Environments: Work closely with compliance and security frameworks to ensure our software meets the strict standards required by iGaming regulatory bodies.

What We Are Looking For

• Strong .NET Expertise: Proven commercial experience with C# and modern .NET versions (experience with .NET 8/9/10 is highly desirable).
• Architecture & Patterns: Solid understanding of both microservices architectures and monolithic codebases, including event-driven design and RESTful API development.
• A Testing Mindset: You don't view testing as an afterthought. You are comfortable with TDD/BDD concepts and testing frameworks (e.g., xUnit, NUnit, Moq, FluentAssertions).
• Regulated Industry Experience: Experience working within compliance-heavy, highly regulated sectors (iGaming, FinTech, HealthTech, etc.) is a massive plus.
• Autonomy & Ownership: A self-starter who is comfortable mentoring peers, making architectural decisions, and taking responsibility for production systems.
• Clear & Contextual Communication: You can articulate complex technical concepts, architectural decisions, and integration risks clearly to both technical peers and non-technical stakeholders (such as Compliance, Product Owners, and external game vendors). You write clean documentation and believe that code isn't finished until it's understandable.
