Role Overview

We're looking for a Lead Game Designer to join the Tripledot Games team. You’ll lead design on a new hybrid-casual game in the idle RPG space. We’re exploring directions that blend idle progression with arcade action or roll-based economies, and you’ll help decide which one we take forward.

Key Responsibilities

• Hands-on: Own the core loop, meta and progression design for a new mobile game, from concept to launch. Build playable prototypes quickly, using AI tools, to test ideas before full production. Design economy and progression systems, including upgrade curves, rewards, gacha and spin or roll mechanics. Balance hybrid monetisation across ads and IAP. Write clear design documentation for art, engineering and product teams. Analyse KPIs, playtests and A/B tests, and turn the results into design changes.
• Leading game design: Set the design direction for the project, working with the product director and studio leadership. Research the market and competitors to find opportunities in new genres. Review design work and share feedback and best practices with more junior designers.

Required Skills, Knowledge and Expertise

• Hands-on: A proven record of senior or lead game design work on live free-to-play mobile games, ideally hybrid-casual. Experience on at least one successful title in idle RPG, coin looter, arcade idle, survivor-like or similar hybrid-casual genres. Experience designing the economy, progression and monetisation of a live game, and tuning them using player data and A/B tests. Experience building playable prototypes yourself with AI tools.
• Leading game design: Experience reviewing other designers’ work and helping them improve.

Strong advantage:

• Experience on two or more of the genres above.
• Experience taking a new game from concept to launch.
• Experience with base building, lighter 4X-style meta or creature collection.
