You can view all your bookings, day after day, wherever you are and optimize your restaurant’s occupation rate. Our client offers a commission-free booking solution that guarantees freedom above all. New technologies thus become the restaurateurs best allies for saving time and gaining customers while ensuring a direct relationship with them.

Their goal is to become the #1 growth platform for Restaurants. They believe that restaurants have become lifestyle brands, and with forward-thinking digital products, restauranteurs will create the same perfect experience online as they already do offline, resulting in a more valuable, loyalty-led business.

You’ll be building and evolving the systems that power multi-location restaurant groups across Europe. Your primary playground is PHP/Laravel on the backend, and you’re comfortable navigating a TypeScript/React frontend codebase, contributing to frontend services when needed.

Beyond the code, they are looking for someone who genuinely enjoys thinking about architecture – someone who forms opinions, defends them with data, and changes their mind when shown a better path. They want a builder who is naturally drawn to new technologies and sees AI-assisted development not as a gimmick, but as a real productivity multiplier.

• Solid TypeScript skills and hands-on experience with TypeScript – you can read, write, and review frontend code confidently
• Strong SQL knowledge – you write queries, understand indexes, and can reason about query performance
• Proven ability to articulate and justify architectural decisions: weighing trade-offs around scalability, maintainability, and explaining the reasoning clearly to peers and stakeholders
• Fluency with REST API design and experience consuming or building JSON integrations
• Comfortable working in Git-based workflows with pull requests, branches, and CI gates
• Active user of AI development tools (Claude Code, Cursor, Copilot, or similar) – you’ve integrated these into your daily workflow and are curious about pushing them further
• A track record of working in Agile environments with cross-functional teams
• Upper-intermediate to advanced English proficiency

Nice to have:

• Experience with React and/or Next.js
• Knowledge of cloud infrastructure (AWS) and containerization (Docker)
• Familiarity with Keycloak (OIDC/OAuth2, B2B/B2C realm configuration, identity providers)
• Exposure to Domain-Driven Design (DDD) or hexagonal/clean architecture patterns
• Experience with state management libraries (MobX, Redux, Zustand, etc.)

In return we offer:

• The friendliest community of like-minded IT-people
• Open knowledge-sharing environment – exclusive access to a rich pool of colleagues willing to share their endless insights into the broadest variety of modern technologies
• Mobilunity Medical Insurance program designed to attend our teams’ needs
• Paid vacations and sick leaves, including 5 paid days per year that don’t require a sick note
• Perfect office location in the city-center (900m from Lukyanivska metro station with a green and spacious neighborhood) or remote mode engagement: you can choose a convenient one for you, with a possibility to fit together both
• No open-spaces setup – separate rooms for every team’s comfort and multiple lounge and gaming zones
• English classes in 1-to-1 & group modes with elements of gamification
• Neverending fun: sports events, tournaments, music band, multiple affinity groups
