Fullstack Laravel/Java/Typescript Engineer

On behalf of our Client from France, Mobilunity is looking for a Fullstack Engineer.

Our client is a table management software and CRM that enables restaurant owners to welcome their customers easily. The app is useful to manage booking requests and register new bookings. 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 the technical backbone of their Payment squad, building and evolving the systems that power payments across our restaurant platform in Europe. Your primary playground is PHP/Laravel on the backend, with a meaningful share of work in a Java/Spring Boot service that owns parts of their payment domain. You’re also comfortable navigating a TypeScript/React frontend codebase and contributing to it 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.

Responsibilities:

• Develop and maintain backend and frontend services for the Payment team using Laravel, Spring Boot, and TypeScript
• Design, document, and defend architectural decisions for new features and refactors, in collaboration with the other developers of the team
• Design and optimize backend systems and databases to serve B2B customers and their guests
• Investigate, diagnose, and resolve application-related issues in production, including payment-critical incidents
• Collaborate with the Product Manager, Designer, and the other developers of the team to scope and deliver new features on a regular basis
• Participate in code reviews and mentoring to maintain engineering excellence across the squad

Requirements:

• 5+ years of professional software development experience, with PHP/Laravel as your primary backend stack
• Working knowledge of Java and Spring Boot, or strong willingness and proven ability to ramp up quickly on a JVM service – you’ll regularly read, review, and contribute to it
• Solid TypeScript skills and hands-on experience – 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
• Prior exposure to payment systems (PSP integrations, 3DS, refunds, reconciliation) or other regulated/financial domains
• 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.)

You are the right fit if:

• You get genuinely curious about new tools, patterns, and frameworks – and you act on that curiosity
• You see AI-assisted development as a craft to develop, not just a shortcut to reach for
• You take ownership of problems rather than waiting to be told what to do next
• You bring care and rigor to a domain where mistakes are visible to users and have financial consequences
• You’re direct in technical discussions and comfortable with disagreement as part of good engineering

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
