Design and implement mathematical models for online slot games, from balancing game mechanics through simulation and testing to publication preparation. This is a remote, full-time project collaboration.

Responsibilities

  • Design slot-game mathematical models, including reel strips or symbol distributions, paytables, trigger frequencies, and mechanic parameters
  • Allocate RTP between base games and bonus modes and tune target volatility for each mode
  • Calculate the cost of bonus buys and feature spins
  • Implement models in Stake Engine Math SDK using Python
  • Run simulations, analyze results, and use an optimizer to tune weights toward target metrics
  • Coordinate game-event structures with the front-end team
  • Document mathematical models, mechanics, and simulation results
  • Support QA testing and assist with uploading games to the platform

Requirements

  • Experience designing mathematical models for slot games
  • Understanding of RTP, hit frequency, volatility, win distributions, and reel-strip design
  • Python skills for implementing game logic and running simulations
  • Knowledge of probability and statistics, including working confidently with large datasets
  • Experience modeling rare large wins and long-tailed distributions for games with maximum wins of at least 30,000 times the stake
  • Intermediate or higher English

Nice to have

  • Experience with Stake Engine Math SDK or an RGS using pre-calculated game outcomes
  • Familiarity with cluster pays and cascading mechanics
