The Lead Game Designer will own the vision, systems, and delivery of experiences that blend delight-first design with rigorous experimentation to improve learning completion, skill verification, and long-term engagement. The role brings together hands-on prototyping in Unity, tooling and simulation work in Python, systems design, and team leadership to create polished, measurable experiences for learners worldwide.

What You'll Do

• Define and own the design roadmap for gamified learning experiences, balancing player delight with measurable learning outcomes and product metrics such as completion and retention.
• Prototype gameplay loops, micro-interactions, and UX flows in Unity to validate mechanics and iterate quickly with design and engineering partners.
• Design progression, reward, badge, and economy systems that support skill verification and career outcomes, using qualitative and quantitative feedback to refine the experience.
• Build reproducible simulations and tooling in Python to support balancing, test design hypotheses, and scale experimentation.
• Run A/B tests and live-ops experiments, analyze results with cross-functional partners, and turn insights into prioritized design improvements.
• Lead and mentor a small team of designers, establish effective processes, review work, and foster a collaborative, user-first design culture.
• Work closely with product, engineering, data, and learning stakeholders to ship well-instrumented features with clear goals and measurable impact.

What You Bring

• 6+ years of professional game design experience, including meaningful work on mobile or casual products and a track record of shipped systems or prototypes.
• Strong hands-on Unity experience for rapid prototyping and iteration across gameplay, UI, and UX flows.
• Practical Python skills for building simulations, tooling, and supporting analysis and balancing work.
• Strong data literacy, including defining KPIs, designing and interpreting A/B tests, and using analytics to inform design decisions.
• Experience designing progression, reward, and economy systems with a focus on engagement, retention, and sustainable outcomes.
• Leadership and mentorship experience, with the ability to support other designers and lead cross-functional initiatives.
• Excellent communication and collaboration skills, with a clear interest in designing experiences that help people learn and grow in their careers.

Nice to Have

• Experience with gamification or learning experience design focused on measurable learning outcomes.
• Background in HR technology, learning and development, or products related to upskilling, credentialing, or career transitions.
• Familiarity with analytics and experimentation platforms such as Amplitude, Firebase, or GameAnalytics, as well as SQL.
• Experience designing onboarding flows, micro-interactions, or accessibility-minded UI polish.
• Based in Spain or elsewhere in the EU to support overlap with core team hours.
