Company Description
BeBetta is a gamified platform designed for gamers who crave excitement, engagement, and real-world rewards. By playing games and making live predictions, users earn BetCoins, which can be redeemed for tangible prizes. Our unique approach blends gaming, predictions, and rewards, driving an immersive experience that revolutionizes user engagement. 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.
