The Role

• We're looking for a mid level and senior .NET Software Engineer on a rolling contract to join our engineering team in Lagos on a hybrid basis. You'll design, build, and scale the core backend services powering our betting platform. This is a hands-on role for an engineer who thrives in fast-paced, high-throughput environments with strong iGaming or adjacent real-time systems experience.

What You'll Do

• Design and maintain high-performance microservices using C#/.NET 8+ on AWS/EKS

• Integrate third-party sports data feeds and managed trading services (Genius Sports, BetConstruct, Oddin.gg)
• Implement Kafka-based event-driven architectures for data ingestion and bet lifecycle events
• Design PostgreSQL schemas (including JSONB hybrid patterns) and Redis caching strategies
• Collaborate with frontend engineers on BFF layer APIs serving web and mobile clients
• Contribute to platform reliability: observability, CI/CD (GitHub Actions), and incident response
• Ensure compliance with NLRC, AML/KYC, and responsible gambling frameworks
• Participate in architecture reviews, code reviews, and mentoring

What We're Looking For

• 4+ years of professional C#/.NET backend development
• Experience building real-time, high-throughput systems (betting engines, trading platforms, fintech, or similar)
• Strong microservices, Docker/Kubernetes, and cloud experience (AWS preferred)
• Solid experience with Kafka or similar message brokers
• Deep PostgreSQL knowledge (query optimisation, JSONB, partitioning) and Redis
• Experience with CI/CD pipelines and automated testing strategies
• Familiarity with sports data feeds, odds compilation, or managed trading integrations is a strong plus
• Understanding of Nigerian gaming regulations (NLRC) or willingness to learn the regulatory landscape
• Based in Lagos or willing to be present in Yaba office 3 days per week

Nice to Have

• Prior iGaming / online betting industry experience
• React/Next.js or React Native exposure
• BFF architectural pattern experience
• Background in blockchain or audit trail systems
• Experience integrating virtual sports or esports providers (Kiron Interactive, Golden Race, Spribe)
