About the Product:

An interactive online entertainment platform delivers a portfolio of browser-based games and real-time features to a rapidly expanding user base. The system addresses challenges of high traffic, low-latency updates, and secure micro-transactions within a social gaming context. It operates a hybrid technology stack that includes a mature codebase built on a widely used DOM-manipulation library alongside modern React and Next.js frameworks. Key technical hurdles include migrating legacy components to a modular architecture, implementing WebSocket-based real-time interactions, ensuring mobile and cross-browser consistency, and integrating payment flows and promotion management interfaces. Strong engineering leadership is essential to maintain stability, drive performance optimizations, and accelerate feature delivery at scale.

About the Role:

As a Senior Frontend Developer, you will own the end-to-end delivery of user-facing features on a complex platform. You will clarify requirements, propose architectural solutions, and implement robust interfaces that meet both legacy and future needs. Reporting to a front-end lead and collaborating with a front-end architect, backend engineers, designers, QA, and DevOps, you will spearhead the migration from a jQuery-based codebase to a component-driven React/Next.js ecosystem. This role demands autonomy, strong communication, and deep technical expertise to modernize build processes, optimize performance metrics, and uphold security best practices. Your contributions will shape the frontend architecture, tooling, and workflows that enable rapid, scalable growth.

Key Responsibilities:

• Enhance and optimize existing jQuery interfaces for performance, stability, and maintainability
• Develop responsive, scalable applications using jQuery, React, and Next.js
• Refactor and modularize large CSS/SCSS architectures to support maintainability and scalable theming
• Ensure high-quality mobile user experience and cross-browser compatibility
• Maintain and extend WebSocket integrations for real-time updates
• Implement front-end security measures, including input validation and secure coding patterns
• Design and define React component architecture to guide progressive migration efforts
• Integrate RESTful APIs and Next.js API routes, coordinating closely with backend services
• Establish performance benchmarking, automated testing, and build pipelines with tools like Vite, Webpack, or Gulp
• Architect centralized state management solutions using Redux, MobX, or similar libraries
• Collaborate with designers to translate UI/UX prototypes into production-ready code
• Develop business-critical features such as payment flows, authentication systems, and promotion management interfaces

Required Competence and Skills:

• 6+ years of frontend development on high-load, production-grade projects
• Deep expertise in jQuery and maintaining legacy codebases
• Strong React.js skills (Hooks, functional components, context, custom hooks)
• Proficiency with Next.js (SSR, SSG, App Router, API routes)
• Mastery of CSS/SCSS, responsive design, CSS Grid, and Flexbox
• Fluency in modern JavaScript (ES6+) and TypeScript
• Experience with asynchronous programming patterns and WebSocket integration
• Proven performance optimization techniques, including bundle analysis and Core Web Vitals
• Familiarity with build tools such as Webpack, Vite, and Gulp
• Expertise in RESTful API integration and front-end security best practices
• Experience resolving cross-browser compatibility and debugging issues
• Knowledge of state management libraries (Redux, MobX, or equivalents)
• Proficient with Git and collaborative development workflows
• Excellent communication skills and proven ability to work autonomously in cross-functional teams

Nice to Have:

• Experience with gradual TypeScript adoption in large codebases
• Basic familiarity with PHP for backend integration
• Experience with testing frameworks (Jest, React Testing Library, Cypress)
• GSAP for advanced animations and interactive UI elements
• Proficiency with design tools (Figma, Zeplin, Photoshop, Sketch)
• Understanding of CI/CD pipelines and DevOps fundamentals

CANDIDATE JOURNEY

Interview with a Recruiter — Interview with CTO — Interview with DevOps — Job Offer

In our team, creativity isn’t about waiting for inspiration—it’s about analytics, behavioral psychology, and data. We are looking for a structured, system-driven Creative Team Lead who can manage creative chaos and translate it into clear business metrics.

Your goal is to build a steady pipeline of high-converting hypotheses, scripts, and pre-landers that hit the bullseye. If you’re ready to be both an inspiring visionary and a tough critic for your team—relying on CPL and CR while fostering growth and talent—we’re excited to see your case studies!

Key Responsibilities

• Team & Process Management: Coordinate the daily workflow of Creative Marketing Specialists and Copywriters, allocate tasks, manage workloads, and ensure deadlines are met.
• Creative Quality Control: Review and approve marketing hypotheses, scripts, pre-landers, and other promotional materials before they go live.
• Data-Driven Decision Making: Regularly track and analyze performance metrics. Guide the team’s direction based on hard data rather than subjective opinions like "looks nice / doesn't look nice."
• Identifying Growth Opportunities: Spot bottlenecks in the current creative production pipeline and implement improvements to boost the team's speed and quality.
• Cross-Functional Collaboration: Work closely with Media Buying, Design, Analytics, and Tech teams to ensure seamless task synchronization.

• Team Development: Conduct regular 1-on-1 meetings, provide constructive feedback, mentor team members, and build a comprehensive knowledge base (standards, guidelines, winning cases).

   

What We Are Looking For

• Background in Creative Marketing: 3+ years of experience building high-performing ad funnels, campaigns, or creative angles.
• Leadership Experience: 1+ years of successfully managing a team (creatives, copywriters, marketers) with a proven track record in delegation and motivation.
• Full-Cycle Production Knowledge: A deep understanding of the entire process—from market analysis and consumer insights to scriptwriting, pre-lander development, and post-test performance analysis.
• Data-Driven Approach: Ability to track, calculate, and interpret key metrics (CPL, Lead CR, FTD CR, etc.).
• Industry Experience: Direct experience in Affiliate Marketing, Media Buying, Performance Marketing, or E-commerce.
• Soft Skills: Highly organized, autonomous, and proactive, with the ability to maintain a healthy, supportive team culture while firmly defending product quality.

Nice to Have

• Experience scaling creative teams or a successful transition from a Senior Creative Marketing Specialist / Creative Lead role in large-scale digital projects.
• Your own proven frameworks for rapid testing of marketing hypotheses.

• Experience building processes from scratch and creating structured knowledge bases that streamline the onboarding of new hires.

   

What We Offer

• 100% Remote: Work from anywhere in the world, as long as you're comfortable and have a stable internet connection.
• High Level of Autonomy: We are strictly goal-oriented, meaning you’ll have the freedom to make decisions and implement your own ideas.
• Stability & Growth: Competitive salary (base rate, discussed individually), a transparent 2–3 month trial period, and a powerful team of experts around you.
• Professional Ecosystem: An established infrastructure (designers, tech support, analytics) that allows the creative team to focus on generating and executing great ideas without drowning in routine.
