[Hiring] Fractional Senior Game Designer @Exient

Role Description

We are looking for an experienced Senior Game Designer to join us on a contract basis to strengthen our design capacity across multiple live and upcoming projects. This is a hands-on role for someone who can hit the ground running: contributing complex design work from day one, raising the quality and velocity of the team, and helping to advance our AI-assisted design workflows.

This is a distinct, self-directed contractor engagement. You will operate as an independent supplier of design services under a contract for services, using your own judgement and working methods to deliver agreed outcomes across our project roadmap.

You will work closely with our existing design, art, engineering, and production disciplines to design, balance, and polish key features, and to flex onto proposals, pitches, and new opportunities as they arise.

What You'll Work On

• Own feature and systems design for live free-to-play games.
• Design against data and player behaviour, working closely with Product, Analytics and Production.
• Deliver a steady stream of seasonal and event content.
• Work across a varied portfolio, including Lemmings and other live and partner titles.
• Contribute to new concepts and pitches, helping shape GDDs, proposals and concept pitches.
• Design within real-world constraints, meeting evolving compliance and regulatory requirements.
• Help push our craft and ways of working forward, including AI-assisted design workflows.
• Partner across disciplines to take designs from documentation to polished features.
• Prototype and pressure-test ideas quickly using rapid iteration and playtesting.
• Be a senior, autonomous member of a small, collaborative team.

AI-Assisted Design Workflow

You'll help elevate the AI-assisted ways of working already part of our design process. Our focus is workflow AI, using AI tools to work faster and smarter.

• Ideation: generating and stress-testing divergent ideas at speed.
• Structured specification: turning rough mechanics into explicit rule sets and documentation.
• Economy and balance: accelerating the arithmetic-heavy work of curves, progression, and tuning tables.
• Rapid prototyping: reaching a playable, testable prototype faster.
• Documentation and iteration: drafting and maintaining design documentation.

Qualifications

• A minimum of five years' game design experience, the majority within a mobile games company.
• A demonstrable track record of shipping and operating live mobile titles.
• A degree in Games Design, Interactive Media, or a related field, or equivalent professional experience.
• Experience working on complex design projects in a fast-paced, multi-project environment.
• A portfolio or case studies that show senior-level design thinking across mechanics, economy, and player experience.

Requirements

• Strong command of core-loop, meta-game, game balance, economy, and monetisation models.
• Excellent understanding of UI / UX and a strong sense of game flow, pacing, and player experience.
• Ability to conceptualise, prototype, and implement game concepts using a range of tools.
• Practical, hands-on experience integrating AI tools into a design workflow.
• Proficiency with design tooling such as Figma, Unity, Git, Jira, Confluence and Claude.
• Confident with data: reading analytics, forming hypotheses, and using KPIs to guide balancing decisions.
• Broad knowledge of games, with genuine passion for casual, mobile, and classic arcade genres.

Ways of Working

• Self-motivated, organised, and able to deliver reliably while working largely autonomously.
• Clear written and verbal communication in English.
• Collaborative and dependable when working across disciplines and time zones.
• Strong sense of accountability and ownership, with openness to self-critique and constructive feedback.
• Comfortable moving between projects and adapting quickly to shifting priorities.
