Job Title: Senior Software Engineer

Why Pinnacle

Pinnacle has been one of the world's leading licensed online gaming companies since 1998. We're known for our "Winners Welcome" policy — we don't limit or ban winning players. Instead of flashy bonuses, we compete on what matters: the lowest margins in the industry, the highest betting limits, and consistently accurate odds. That's why sharp bettors and professional players treat Pinnacle as the benchmark for the rest of the market.

Our edge is precision — and the platform has to be just as sharp. That means engineering teams building low-latency, high-throughput systems where correctness and reliability aren't aspirational, they're table stakes.

About the role

This is a backend engineering role. You'll join a newly forming team building the systems behind real-time trading, risk management, and core platform services. The domain is established, but the team is being built from the ground up. This is a rare chance to shape how a team works, not just what it ships.

This is a domain-heavy role with significant ownership — you'll need to understand the business logic as deeply as the code, because the two are inseparable here. The work is a mix of greenfield development and evolving complex legacy systems. You'll make architectural decisions that directly affect how the platform performs under load, how quickly we can ship, and how reliably we operate in production.

What you'll do

• Design, develop, and maintain high-performance backend services using .NET in a low-latency, high-throughput environment.
• Build and maintain real-time data pipelines across message brokers, caching layers, and relational databases.
• Navigate and extend legacy systems while ensuring backward compatibility.
• Diagnose and resolve production issues using alerts, dashboards, and log analysis.
• Own the deployment lifecycle for your services — CI/CD pipelines and containerization.

Representative projects

• Building and maintaining integrations with multiple upstream data feeds, consolidating and normalizing data at high volume in real time.
• Designing low-latency integration pipelines to and from third-party providers where throughput and reliability are critical.
• Evolving core platform services to support new business requirements while keeping existing consumers stable.

You may be a good fit if you have

• 5+ years of professional software development experience in .NET.
• Strong experience building highly scalable, high-performance distributed systems and microservices.
• Comfort working in a domain-heavy environment where understanding complex business logic is as important as the code itself.
• Proven experience with message-oriented middleware (e.g., RabbitMQ, Kafka).
• Experience with REST APIs, gRPC, or WebSockets.
• Experience with Redis, Kubernetes, and cloud platforms (Azure preferred, AWS also valued).
• Experience with observability tools (e.g., Splunk, Grafana, OpenTelemetry).
• Experience with AI-assisted development tools (e.g., GitHub Copilot, Cursor, Claude Code).
• The ability to work autonomously with minimal direction — small team, high ownership, fast pace.
• Degree or Diploma in Computer Science or related field (or equivalent experience).

Strong candidates may also have

• Experience in domains with complex business rules (e.g., financial services, trading, or similar).
• Experience with simulation-based or complex integration test automation.
• Experience with GitOps and CD tools (e.g., Argo CD).
• Experience with actor model frameworks (e.g., Akka.NET).
