Job description

Altamira is a software development outsourcing company. We provide solutions that make a tangible impact on our client’s growth and productivity. With domain knowledge across product and technology development, we aim to provide cost-efficient solutions without compromising quality. We are driven to deliver the best, every single time.

Altamira service delivery teams currently span Slovakia, Ukraine, and the Middle East, and we have ambitions to expand our footprint to meet the growing demand across Europe and into our primary growth markets in the UK and the US. In terms of industry verticals, we are focused on EdTech, Fintech, eCommerce, and Pharma.

We are looking for a Full-Stack Developer (Node.js + React) to join our team and work on a long-term project for an international client. This is an outstaffing engagement, meaning you will be fully integrated into the client’s team and collaborate closely with their engineers, product managers, and stakeholders.

Requirements

Back-end (Node.js, with PHP/Laravel exposure)

• Deep, hands‑on experience with Node.js in production environments
• Experience designing and implementing RESTful APIs
• Understanding of backend architecture patterns (layered architecture, modular design, separation of concerns)
• Solid understanding of asynchronous programming, the event loop, and performance considerations in Node.js
• Experience working with SQL databases, including query optimization, transactions, and migrations
• Knowledge of authentication and authorization mechanisms (JWT, OAuth, role-based access)
• Experience with error handling, logging, and monitoring in back‑end services
• Ability to write maintainable and testable code (unit and integration tests)
• Practical experience working with PHP and Laravel in production environments
• Ability to maintain and extend existing Laravel‑based services
• Comfort working with and debugging legacy PHP/Laravel codebases

Front-end (React.js)

• Strong experience building complex applications with React
• Confident use of modern React patterns (hooks, context, controlled components)
• Experience with state management solutions (Redux, React Query, or similar)
• Ability to design and implement scalable component architectures
• Strong understanding of front‑end performance optimization (memoization, rendering control, code splitting)
• Experience working with forms, validation, and complex UI state
• Experience integrating front‑end applications with APIs and handling asynchronous data flows
• Ability to maintain consistent UI/UX in large codebases

Responsibilities

• Develop and maintain back‑end services using Node.js and TypeScript
• Design, implement, and evolve RESTful APIs
• Maintain and extend existing PHP and Laravel services
• Build and maintain complex front‑end applications using React
• Collaborate closely with the client’s team on feature development and technical decisions
• Ensure code quality through testing, code reviews, and best engineering practices
• Work with existing and legacy systems, improving stability and maintainability
• Take ownership of features end‑to‑end, from implementation to delivery
• Contribute to performance, reliability, and scalability improvements across the full stack
