This will become one of the most powerful growth drivers for the entire company and especially for the marketing team. That’s why we’re looking for an experienced Creative Producer to strengthen our current team.

What you will do:

• Work closely with the Head of Marketing to execute the creative strategy and achieve UA KPIs.
• Write detailed creative briefs and provide feedback — owning tasks from idea to final delivery, ensuring quality control.
• Give daily feedback to designers on concepts and iterations.
• Track trends in mobile advertising, research and analyze competitors’ ads.
• Work with UA data to form hypotheses and determine future creative directions.
• Generate ideas and participate in creative brainstorms, understanding each hypothesis and the problem it solves.
• Collaborate with the product and UA teams to achieve the best results.
• Manage a small production team, improve processes, and contribute to developing the creative department.
• Implement innovative formats and ideas, testing unconventional approaches to find hit concepts.

Key requirements:

• At least 3 years of experience as a Creative Producer in the casual mobile games industry.
• Ability to write clear briefs for the creative team; strong communication and argumentation skills.
• Ability to work with analytics, key metrics of ad campaigns and product performance; make data-driven conclusions and decisions.
• Experience producing Playable Ads, understanding tools and technologies (or a strong desire to learn quickly).
• Understanding of the target gaming audience, its preferences and behaviors.
• Knowledge of current mobile advertising trends and ability to apply them in practice.
• Ability to provide timely, constructive feedback to improve concept quality.
• Creativity, strong visual taste, broad creative exposure, understanding of modern styles and design trends.
• A relevant portfolio with examples of successful creatives.
• Experience with AI tools for creative production or workflow optimization is a plus.

What we offer:

• The opportunity to influence products and processes, with a high degree of ownership.
• A team where everyone genuinely loves what they do.
• Maximum transparency and minimal bureaucracy.
• Flexible start to the day — you can begin work from 11:00.
• Official salary and a solid benefits package.
• Conferences, courses, and knowledge sharing — everything you need for professional growth.
• Free optional sessions with a psychologist — we care about mental well-being too.
• High-end hardware and licensed software only.

Kosmos Games is a gaming company leading the publishing of web games and focusing on social casual mobile games. Our titles — Solitaire Social, Mahjong Social, Yatzy Social and others — consistently rank in the Top Grossing Facebook Instant Games (positions 10–20). The company is now entering an active phase of mobile expansion.

We are looking for a UA Lead / Performance Marketing Lead who will own the strategy and execution of user acquisition for our key products (web for retention, mobile for growth), build a scalable and experimental UA system, and become one of the key drivers of revenue growth.

What you will do

• Grow the revenue and profitability of the portfolio through efficient web & mobile UA: identify, validate, and scale profitable “product × channel × creative” combinations.
• Build a systematic and scalable UA engine that does not require constant hands-on involvement from the CMO: processes, reporting, automation, control points instead of micromanagement.
• Act as a partner and leader for Product, Creative, and Analytics teams: jointly search for growth opportunities instead of “spending on autopilot.”

Required experience and skills

• Deep hands-on experience with Facebook Ads and Google Ads (web and/or mobile) in performance format, with monthly budgets from tens of thousands of dollars.
• Experience scaling games or similar products to profitable UA (ideally — casual, social, casino, or board games).
• Strong analytical skills: unit economics, cohorts, LTV/CAC, ROI, understanding how creatives and channels impact project P&L.
• Ability to set and validate hypotheses without emotional attachment: evaluate value vs. risks & complexity, kill non-working ideas quickly.
• Experience managing people (minimum 2–3 team members) or a strong track record of mentorship and managing contractors/agencies.

What we offer

• Real product impact: you will work with games that already generate stable revenue and lead their niche, as well as mobile products we aim to accelerate into new growth.
• Autonomy and trust: we expect mature decisions and alternative points of view — micromanagement is not part of our culture.
• A strong senior team: UA, creatives, analytics, producers, and a CMO with deep experience in scaling games and building processes.
• Lean, productive processes: OKRs, focus on growth levers and experimentation, regular retros and check-ins instead of endless meetings.
• Remote work with flexible hours, a distributed team, and a high performance-based compensation level.
