Slot Game Creator (Game Design & Math)

RAISE ENGINE; Manila; Remote; PHP 240,000 - 480,000; Full time

Job summary

Raise Studio in the Philippines is seeking a versatile slot game designer to turn themes into shippable, math-driven titles. You will define reels, features, progression, and win presentation, then tune and prove RTP via simulations.

The role requires producing engine-ready math configs using Python/TypeScript/C#, and collaborating with art, QA, and backend teams for a smooth release. As an independent contractor or FTE, you will deliver robust specs and math packs, support certification needs,

Qualifications

• Demonstrated ability to design slot games with clear mechanics and feature sets.
• Strong applied probability and expected-value reasoning with ability to defend RTP numbers.

Responsibilities

• Design game concepts from theme to spec including reels, features, progression, and win presentation.
• Tune math models: payouts, paylines/ways, free spins, multipliers, cascades, buy features, and max-win caps; simulate RTP and volatility.
• Create engine-ready math config JSON matching platform specs and translate emulations to backend-ready configs.
• Prepare certification packs with RTP, volatility, hit-frequency analyses, and simulation evidence for QA/licensing.
• Coordinate with art and frontend to assemble playable, correct games (including mobile portrait).
• Iterate RTP bands against hosting tiers and optimize live performance after release.

Job description

Engagement: Independent contractor, full-time equivalent or per-title, remote

Reports to: Raise Studio lead, under CTO for engine matters

Works alongside: 3D/2D art, Games Integration, QA, media

WHY THIS ROLE EXISTS

Raise Studio is the proof case for Raise Engine. Every first-party title we ship demonstrates to the creator cohort what the engine can do and gives operators a reason to put us on the top row of the lobby.

This role turns a theme into a shippable, mathematically sound, commercially tuned slot game.

WHAT YOU'LL OWN

• Game design. Concept to spec: theme, mechanic, reel structure, feature set, progression, win presentation, and the emotional shape of the session.
• Game mathematics. Reel strips, weighted reels, paytables, paylines or cluster/ways evaluation, feature triggers, free spins, multipliers, cascades, buy features, and max-win caps. Tune to a target RTP band and volatility profile and prove it by simulation.
• Math configuration. Produce engine-ready math config JSON to the platform specification — correct field names, award modes, and emission format. Translate any TypeScript emulation into a backend-ready config that matches spin-for-spin.
• Certification pack. RTP report, volatility and hit-frequency analysis, max-win exposure, and simulation evidence sufficient for QA sign-off and any licensing or certification requirement.
• Build coordination. Work with art and frontend to get the game assembled, playable, and correct — including mobile portrait.
• Commercial tuning. RTP band selection against our hosting tiers, and iteration on live performance data once a title is in market.

WHAT WE NEED

• Demonstrable slot titles shipped — you can point to games in market and explain the maths behind them.
• Strong applied probability and expected-value reasoning. You can build a simulation and defend an RTP number to a third party.
• Fluent in at least one of Python, TypeScript, or C# for math simulation and config generation.
• Deep familiarity with slot mechanics as a player and as a designer: what makes a session feel good and what makes it feel cheap.
• Ability to write a game specification that art, frontend, and QA can all execute from without ambiguity.

STRONG ADVANTAGE

• Experience with a remote game server / RGS math SDK and producing configs consumed by a backend.
• Cluster-pays, Megaways-style, hold-and-win, and cascade experience.
• Prior work through a certification body (GLI, BMM, iTech Labs).
• Can also produce or direct the art direction for a title.

SUCCESS CRITERIA

• 30 days — One full game specification and validated math config delivered, passing QA math verification on first submission.
• 60 days — First title live on an operator lobby. Second title in build.
• 90 days — Repeatable title production process documented — spec template, math config template, simulation harness — so the studio can run multiple titles concurrently.
