Job Description

Fliff unpacks sports gaming into social, free-to-play games for all types of sports fans. We've built a social sports gaming experience that allows users to compete for leaderboard positioning, to achieve badges and build their status within the game.

We are pioneering play-for-fun sports gaming, with our flagship social sportsbook experience that includes sweepstakes promotions and loyalty rewards. We provide sports fans with fun, engaging, and free-to-play alternatives to real money gaming.

  • Build scalable solutions that can handle large volumes of traffic
  • Write clean, maintainable, and efficient code
  • Contribute to testing strategies (unit, integration, end-to-end) to ensure quality and reliability
  • Participate in code reviews, learning from feedback and providing constructive input to peers
  • Troubleshoot and resolve production issues with support from senior engineers
  • Continuously learn and grow your skills while contributing to team knowledge-sharing

  • Required Skills & Experience
  • 2+ years of overall software development experience
  • Proficiency in Go (or another backend language with interest in learning Go)
  • Understanding of distributed systems or microservices
  • Solid grasp of data structures, algorithms, and backend development best practices
  • Experience with relational and/or NoSQL databases
  • Exposure to cloud providers (AWS, GCP, or Azure)
  • Familiarity with CI/CD and containerization (e.g., Docker, Kubernetes)
  • Knowledge of observability tools (Datadog, Prometheus, Grafana, OpenTelemetry)
  • Excellent communication and problem-solving skills, with the ability to work effectively in a collaborative team environment

  • We are a multinational company with our headquarters based in Philadelphia, and offices in New York, Austin, and Sofia, Bulgaria. Wherever we are in the world, we pride ourselves on being a close-knit, focused team that is welcoming and friendly, and the work that we do is always interesting and rewarding.
