    • Devise complete mathematical models for video slots: pay-tables, feature probabilities, RTP, volatility profiles, jackpots, and max exposure limits.
    • Build large-scale simulations (100 M+ spins) in Python to validate models, stress-test edge cases, and generate compliance reports for labs (GLI, iTech Labs, etc.).
    • Collaborate with the team to align maths with theme, core loop, and business goals; adjust parameters to hit target GGR, hit frequency, and retention curves.
    • Perform competitive teardown of market-leading titles, extract insights on why they succeed, and translate findings into new concepts or balance tweaks.
    • Analyse live performance data, compare against forecasted curves, and recommend tunings that optimise both player experience and operator revenue.

       

      Requirements:

    • 2+ years in slot mathematics or equivalent quantitative role within released real-money or F2P slots.
    • Hands-on participation in at least two commercially successful slot projects (e.g., top-ranked on SlotCatalog or GGR > $1 M in the first 90 days).
    • Strong command of probability theory, combinatorics, and statistical inference; ability to explain complex math to non-technical stakeholders.
    • Proficiency with Python (NumPy, pandas, SciPy or similar) for simulations and data analysis.

    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., 8Γ—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.
