Senior Lead Developer (React, React Native, Node.js)

Hi! We are looking for a Senior Lead Developer to guide a small development team and drive the successful delivery of our projects. In this role, you will be the key link between technical strategy and execution. You will work closely with our Software Architect to define the tech stack and direction, while taking full ownership of the implementation, code quality, and team management.

Since we work exclusively in English, strong communication skills are essential, as you will communicate daily with the Product Owner and the Architect.
 

🔧 The Tech Stack We work with a modern, high-performance stack. You will implement architectural patterns using:

• Frontend: React, Vite, React Hook Form, Tailwind, Zustand, TanStack React Query, Next.js
• Backend: Node.js (Koa.js, Express.js), Prisma, tRPC, Zod, Redis, Socket.IO, PostgreSQL
• Mobile: React Native (Expo/CLI)
   

🚀 What will you be working on? You will lead the development lifecycle, ensuring that the Architect’s vision becomes a high-quality reality.

• Technical Collaboration: Work closely with the Software Architect to discuss technology choices, define the direction of projects, and implement scalable architectures.
• Team Leadership: Lead a small team. You will break down features into technical tasks, assign them to developers, and manage the delivery timeline.
• Product Improvement: Communicate proactively with the Product Owner. You are expected to understand the product vision, suggest functional improvements, and find ways to make the user experience better.
• Quality Assurance: You own the code quality. You will perform in-depth code reviews to ensure the team follows the defined architecture and best practices.
• Hands-on Development: You will remain hands-on, writing code for critical features and solving complex technical challenges across web and mobile.
   

👨‍🏫 Collaboration & Support You are not working in a vacuum. You will have the high-level support of a Software Architect for complex decision-making, while you provide mentorship and guidance to the developers on your team.
 

📍 Where will you work from? This position is fully remote. You will be working for a company based in the Czech Republic.
 

✅ Who are we looking for?

• Senior-level experience (5+ years) in full-stack development (React+React Native/Node.js).
• Execution Focus: You know how to take a high-level architectural design and turn it into actionable tasks for a team.
• Leadership Skills: Experience doing code reviews, planning sprints, and unblocking other developers.
• Product Mindset: You are not just a programmer, you care about the end product and actively communicate with the Product Owner to improve it.
• Collaborative Spirit: You are comfortable discussing and debating technical approaches with a Software Architect.
• React Native experience is required.
   

🎯 What will you gain?

• Influence: A key role in shaping the product and the team culture.
• Growth: Close collaboration with a Software Architect, providing a great opportunity to deepen your architectural knowledge.
• Stability: Long-term collaboration on real, impactful projects.
