Fastboy Marketing

Overview of job

We’re not just building products — we’re building a place where people grow. At our core, personal development is a priority. We want every team member to level up alongside the company through hands-on projects, cutting-edge tools, and industry best practices.

Our clients expect nothing less than excellence, and that high standard fuels everything we do.

We’re looking for a Mid/Senior Frontend Engineer ready to take ownership, solve tough problems, and build products people actually love using.

What you'll be doing:

• Develop high-performance web applications that are reliable and scalable.
• Analyze requirements and maintain clear, up-to-date technical documentation.
• Contribute ideas and solutions to enhance our products.
• Write clean, maintainable, and well-documented code.
• Participate in all phases of the product development lifecycle — from analyzing user requirements and designing system architecture to coding, testing, and deployment.
• Build front-end interfaces that deliver an advanced and intuitive user experience.
• Create reusable components/modules for responsive websites.
• Integrate with API endpoints or Mercure for real-time content updates.
• Ensure developed pages and software have pixel-perfect UI/UX.
• Optimize front-end performance to ensure consistent rendering across all major browsers.
• Collaborate closely with the backend team to ensure seamless integration between front-end and back-end systems.

• Competitive pay — Above-industry-standard salaries with a 13th-month bonus.
• Great benefits — Full insurance coverage and regular team-building activities.
• Flexibility — Friendly working environment and flexible working hours.
• Growth-focused — We invest in you as much as in our products. Whether it’s improving your English, mastering a new design tool, developing your design thinking, or exploring a new skill, we’ll support your growth every step of the way.
• Meaningful work — We work hand-in-hand with clients, fully investing in their product development to create solutions with true market potential.
• Balanced culture — We respect both products and technology equally, ensuring every team member understands, believes in, and contributes to what they’re building.
• Work-life respect — We stick to a sustainable pace with standard 8-hour days, Monday to Friday — no burnout culture here.
• Agile and adaptive — We work in sprints with realistic goals, improving processes continuously to match our true velocity.
• Ownership & autonomy — You’ll have the freedom to experiment, innovate, and shape your role, with a team that’s always open to better ways of working.
