About the Role

You’ll be part of a remote-first team developing the core features that power a modern sportsbook, including trading engines, odds services, and high-availability APIs.

• Develop and maintain scalable RESTful and gRPC APIs
• Work with Microsoft Orleans for distributed application development
• Integrate Apache Pulsar for real-time message streaming
• Design performant data solutions using SQL Server and PostgreSQL
• Optimize systems for low latency, fault tolerance, and high concurrency
• Participate in Agile ceremonies and collaborate with developers, DevOps, and product managers
• Review code, ensure testing coverage, and contribute to improving development practices
• Triage and resolve production issues in a fast-paced environment

What You Bring

• 5+ years of experience working with .NET (C#) in backend environments
• Strong understanding of distributed systems, messaging, and microservices
• Experience with Microsoft Orleans or similar actor-based frameworks
• Familiarity with Apache Pulsar, RabbitMQ, or Kafka
• Proven experience with SQL databases, ORMs, and performance tuning
• Solid grasp of CI/CD, containerization (Docker/Kubernetes), and cloud platforms (Azure or AWS)
• Excellent written and spoken English communication skills
• Strong troubleshooting skills and ability to work independently in a remote setup

Bonus Points For

• Direct experience in sportsbook, betting, or trading system development — strongly preferred
• Understanding of betting mechanics, odds calculations, and market types
• Familiarity with compliance and uptime standards for gaming environments
• Certifications (Microsoft, AWS, etc.) or contributions to open-source projects

What We Offer

• Long-term engagement with a rapidly growing tech organisation
• Fully remote setup within European time zones (flexible hours around CET)
• Competitive salary package depending on experience and location
• B2B Contract | Equipment budget | Health insurance (where applicable)
• Learning & development budget, professional certifications
• Fast-paced, collaborative team culture with clear ownership and autonomy
