We are a high-growth, data-driven, and gamified tech startup committed to innovation and impact.

The Opportunity:

BeBetta is building the future of fan engagement. To do this, we need a backend that can handle millions of concurrent users making real-time predictions during live events. This requires a shift in our technology towards systems built for massive scale and low latency.

That’s where you come in. We are looking for a Senior Backend Engineer to lead our transition to a Go-based microservices architecture. You will be the driving force behind our most critical systems—the prediction engine, the rewards ledger, the real-time data pipelines. While our roots are in Node.js, our future is in Go, and you will be instrumental in building that future.

What You'll Achieve:

• Architect our core backend in Golang: You will design and build the services that are the backbone of the BeBetta experience, ensuring they are blazingly fast and incredibly reliable.
• Solve hard concurrency problems: You'll tackle challenges unique to real-time gaming and betting, ensuring fairness and accuracy for thousands of simultaneous user actions.
• Drive technical strategy: You will own the roadmap for evolving our architecture, including the thoughtful migration of essential services from Node.js to Go.
• Elevate the engineering bar: Through mentorship, exemplary code, and architectural leadership, you will help make our entire team better.
• Ship with impact: You will see your work go live quickly, directly enhancing the experience for our growing user base.

What You'll Bring:

• A track record of building and deploying high-performance backend systems in Golang.
• Senior-level experience (4+ years) in system design, microservices, and API development.
• Pragmatic experience with Node.js and an understanding of how to manage and migrate a monolithic or service-based system.
• Deep knowledge of database principles (PostgreSQL preferred) and high-performance data access patterns (using tools like Redis).
• Expertise in modern infrastructure: Docker, Kubernetes, and a major cloud provider (GCP/AWS).
• A strong belief that testing, observability, and clean architecture are not optional.
• An innate curiosity and a passion for solving complex problems, whether they're in code or on a whiteboard.

Why You'll Love Working Here:

This isn't just another backend role. This is a chance to put your fingerprint on the foundational technology of a fast-growing company in the exciting world of sports tech and gaming. You'll have the autonomy to make big decisions and the support of a team that's all-in on the mission.
