Python Game Math Developer – Slot Engine in Olabin Diamonds

We’re looking for a strong back-end engineer with a passion for probability, discrete-event

systems and casino math. You’ll own the server-side logic for brand-new video-slot titles

featuring custom mechanics and switchable volatility profiles (medium / high). Working

alongside game designers and front-end teams, you’ll transform design docs into fully

simulated, production-ready slot engines, complete with optimisation pipelines and S3

deployment.

What you’ll do

• Design and implement novel slot mechanics (e.g., 8×8/dynamic boards, unique win conditions, dual reel sets for volatility switching, split/ways/transition mechanics, etc ).
• Extend a Python-based math framework: build config files, reel-strip loaders, payout tables, win evaluators, cascading/tumbling logic, free-spin rounds and wallet managers.
• Emit well-structured JSON events for the client SDK (spins, wins, multipliers, feature triggers, volatility toggles, etc.).
• Create simulation runs (millions of rounds) to verify RTP, hit-rates, max-win distribution and other KPIs.
• Tune win distributions with a companion optimisation tool (Rust binary) and produce balanced lookup tables.
• Package output assets (books, lookup tables, configs) and automate uploads to AWS S3.
• Collaborate with front-end and QA to validate event schemas and gameplay flow.
• Write clear docs and contribute sample games to our internal knowledge base.

Must-have experience

• 3 + years professional Python (async/multithreading, typing, testing).
• Strong applied probability / statistics; comfortable deriving RTP, volatility, hit-rate, max-exposure.
• Previous work on slot, RNG or other real-money game logic.
• Deep understanding of state machines, event-driven architecture, and JSON serialization.
• Competence with Pandas / NumPy for simulation analysis and Matplotlib (or similar) for visual checks.
• Experience generating and processing large simulation datasets (GB-scale).
• Version control (Git) and CI basics; able to ship production code that passes review.
• Fluent English; able to translate game-design language into deterministic algorithms.

Nice to have

• Exposure to high-performance algorithms.
• AWS SDK (boto3) and S3 workflows; knowledge of object hashing / SHA verification.
• Familiarity with lookup-table–based game balancing.
• Experience with Zstandard or similar fast compression formats.
• Knowledge of front-end signalling for slots (PixiJS, WebSockets, TypeScript event models).
• Interest in statistical optimiser design (Gaussian sampling, volatility scoring).

Why us

• Green-field projects where you influence mechanics and math from day one.
• Fully remote, flexible hours (core overlap with CET/Lisbon time).
• Small, senior team — quick decisions, no corporate overhead.
• Chance to craft highly visible real-money titles played by millions worldwide.
