[Join ZOZO Group] Full-Stack Engineer Wanted for Product Delivering Fragrance OnlineTranslated from Japanese

▼Job Details Kararia is a product that delivers "fragrance" online, and we are tackling the inherently difficult challenge of how to help users choose scents they cannot experience through a browser, using data x UX x operations. The market for "fragrance" that we are currently developing is growing year by year, and as of 2026, we have surpassed 900,000 cumulative members and continue to grow. As a pioneer in the "perfume decanting subscription" model, we have built a strong market position by accumulating high entry barriers such as logistics construction and brand relationships. ■Reason for Hiring We operate "Kararia," a comprehensive fragrance platform. We are now joining the ZOZO Group to aim for further business growth! From now on, we will fully leverage ZOZO's overwhelming customer base, EC/logistics know-how, and data to deliver "Kararia" to more people. We are looking for colleagues to build the future of High Link together as core members of an organization that will achieve rapid growth from here, without being bound by existing frameworks! ■Future Outlook & Product Appeal There are abundant technical challenges, such as developing recommendation engines that combine ZOZOTOWN's overwhelming customer and purchase data with Kararia's fragrance data, dramatically updating the UX, and launching new businesses. This is an environment that can only be experienced now, where you can challenge 0 to 1 development with the speed and discretion of a startup while utilizing the powerful assets of a mega-venture! ■Job Responsibilities - Development of new features - Design and development of new products - Resolution of technical debt - Solving performance issues - Improvement of development environment, DevOps - Minor experience improvements within the service ▼Required Skills/Experience - Practical experience as a web engineer - Practical experience in service development using Ruby on Rails - Practical experience in development using Next.js (React) - Ability to quickly input and enjoy the knowledge necessary for product improvement, regardless of front-end or back-end domains ▼Welcome Skills/Experience - Experience in growth development for services with over 10,000 users - Infrastructure construction experience using AWS - Experience in designing EC services ▼Ideal Candidate Profile - Those who propose and act on their own initiative when they think, "Wouldn't this be better if we did it this way?" - Those who enjoy discussing "why this feature is necessary" with PdMs and designers, not just writing code. - Those who have intellectual curiosity in seemingly mundane but profound domains such as logistics and inventory management. - Those who find fulfillment in achieving results as a team. - Those who routinely enjoy learning new technologies and knowledge. - Those who can make realistic judgments according to the situation, rather than pursuing perfect design. ▼Job Appeal ■ Develop for a growing B2C service We have 900,000 users, but there is still much potential in the fragrance market. You can gain experience solving technical challenges that arise with the increase in user numbers. ■ Develop across domains with discretion Due to the small team structure and a culture that emphasizes cross-domain development, each member can work with discretion. The distance to PdMs and designers is close, creating an environment where you can have ownership of the entire product. ■ Product-Oriented Team We are a team of engineers who value technology while also being interested in improving the product from a user's perspective. This is an ideal environment for those who want to dedicate themselves to product development towards the same goal, transcending job roles. ▼Development Environment - Backend: Ruby, Ruby on Rails - Frontend: TypeScript, React, Next.js, Tailwind CSS - Infrastructure: AWS, ECS (Fargate), Docker, Terraform - Database: MySQL (RDS), Redis - Other: GitHub, GitHub Actions, Sentry, Datadog - AI Development Tools ▼Employment Type Full-time employee (No fixed term) ▼Probationary Period 6 months ▼Salary Annual salary ¥5,500,000 - ¥9,000,000 ▼Annual Salary Lower Limit (¥10,000s) 600 ▼Annual Salary Upper Limit (¥10,000s) 900 ▼Work Location 1-18-9 Nishi-Gotanda, Shinagawa-ku, Tokyo 141-0031 Gotanda NT Building 4F Work location: Head office or location designated by the company Scope of change: Location determined by the company ▼Working Hours Flextime system (Core time: 11:00 - 15:00) Standard working hours: 8 hours per day *Monthly prescribed working hours: Approximately 160 hours ▼Break Time 1 hour during working hours ▼Overtime Work Yes ▼Holidays, Paid Leave, Special Leave - Saturdays, Sundays, and national holidays - Year-end and New Year holidays - Anniversary Leave - Sick Leave - Refresh Leave - Paid Leave - Congratulatory and Condolence Leave - Over 120 days off per year ▼Benefits - Full coverage for "ChatGPT Plus" and "Claude Pro" fees (Claude Max provided for engineers) - "Github Copilot" implementation - Transportation allowance (up to ¥30,000) - Social insurance complete - Labor insurance complete - Health checkups - Qualification acquisition support/allowance available - "Kararia Fragrance Subscription" employee discount program - Office surrounded by fragrance items - Display provided (all positions) - Book purchase subsidy system - Darts and table tennis tables We highly value members' opinions regarding benefits and create a fun and comfortable working environment through bottom-up initiatives. ▼Allowances - Transportation allowance (up to ¥30,000) ▼Insurance Enrollment - Social insurance complete - Labor insurance complete ▼Measures to Prevent Passive Smoking at the Workplace No smoking on premises Smoking area available within the office (cigarettes only outside the premises) ▼Education, Skill Improvement, Career Advancement - Qualification acquisition support/allowance - Book purchase subsidy system ▼Health Health checkups available ▼Interview/Selection Process Casual meeting => 1st Interview => 2nd Interview => Reference Check => Final Interview => Trial Employment => Offer *The duration and content of the trial employment will be discussed considering the candidate's situation. ▼Other Team Introduction Document https://recruit.high-link.co.jp/engineer Tech Blog https://tech.high-link.co.jp/ Scope of change: Duties determined by the company
