• Knowledge of optimization methods (automated tuning of reels and tables to target parameters: genetic algorithms, simulated annealing, linear programming).
• Experience with crash games, instant games and other non-standard formats.
• Understanding of how math integrates with the game client and server.
• Publications, conference participation (ICE, SiGMA, G2E) and involvement in industry communities.

• Test ad placements, formats, and messaging without harming reader trust
• Analyze performance and continuously improve monetization strategy

Scaling & Team Leadership

• Collaborate closely with writers, AI tools, designers, and growth teams
• Build repeatable processes, guidelines, and quality standards
• Provide weekly performance insights and improvement recommendations
   

Requirements

• Strong experience in email marketing
• Deep understanding of email performance metrics: open rate, CTR, conversions, revenue per send
• Hands-on experience managing multiple email campaings at scale
• Comfortable using AI tools
• Strong editorial and layout instincts (formatting, hierarchy, readability)
• Excellent organization — able to manage 15–20+ newsletters simultaneously
• Strong QA mindset: zero tolerance for broken links, typos, or formatting errors
• High level of English: C1
   

Nice to Have
