Senior .Net Developer

Las Vegas, NV

Fusion HCR is Hiring!

Position: Senior .NET Developer (Backend / Distributed Systems)
Location: Onsite – Las Vegas, NV
Type: Full-Time, Direct Hire
Industry: Casino, Gaming & Sportsbook Technology

Position Overview

Fusion HCR is seeking a Senior .NET Developer with deep backend expertise to design and build scalable, high-performance systems supporting enterprise sportsbook and gaming platforms.

This is a senior-level engineering role requiring strong hands-on experience with modern .NET, distributed systems, containerized environments, API development, event-driven architectures, and SQL Server. The ideal candidate has experience building resilient, transaction-heavy systems in regulated environments and understands how to design services that scale.

This is not a junior or mid-level role — we are seeking engineers who can architect, build, and own critical backend components.

Key Responsibilities

  • Architect, design, and develop scalable backend systems using C# and modern .NET (.NET 6/7/8)

  • Build robust RESTful APIs and service-based architectures

  • Design and implement event-driven systems using message brokers (Kafka, RabbitMQ, Azure Service Bus, etc.)

  • Develop and maintain microservices running in containerized environments (Docker, Kubernetes)

  • Write clean, maintainable, testable code following SOLID principles and domain-driven design concepts

  • Optimize and tune SQL Server databases, stored procedures, indexing strategies, and performance

  • Build systems that support high-volume, real-time transaction processing

  • Collaborate with DevOps on CI/CD pipelines, deployments, and production support

  • Participate in architectural discussions and mentor other developers

  • Support secure coding practices in a highly regulated gaming environment

Required Qualifications

  • 7+ years of professional software development experience

  • Deep hands-on expertise in C# and .NET

  • Strong experience designing and building APIs and distributed systems

  • Experience with containerization (Docker) and orchestration (Kubernetes preferred)

  • Experience implementing message brokers and event-driven architectures

  • Strong SQL Server experience including performance tuning and query optimization

  • Experience working in high-availability, transaction-heavy systems

  • Strong understanding of microservices architecture patterns

  • Experience with Git and modern development workflows

  • Ability to work onsite in Las Vegas

Highly Preferred

  • Sportsbook or real-time wagering platform experience

  • Experience with Blazor (Server or WebAssembly)

  • Experience with MAUI (cross-platform UI development)

  • Azure cloud or hybrid-cloud experience

  • Experience in regulated industries (gaming, finance, healthcare)

  • Automated testing (unit/integration) and CI/CD pipeline experience
