Fullstack Node.js Developer

Hi there!

We are Tooploox, an AI software development company offering custom AI solutions and services. We help innovative companies and startups design and build digital products with generative AI, mobile, and web technologies.

Our team, consisting of nearly 170 experts including our R&D team of over 40 engineers, many with PhDs, has pioneered AI solutions across industries like healthcare, fashion, and ecommerce. We’ve published over 15 research papers in top conferences like NeurIPS and ICML.

In this role, you’ll be part of a crossfunctional team working on diverse projects – from earlystage MVPs to longterm scalable systems. We value autonomy, clear communication, and a pragmatic approach to problem solving.

Feel invited!

What you will do:

• Work with a variety of clients — from dynamic startups to established corporations.
  
• Take full ownership of your work — from initial discovery and planning to delivering tested, highquality features.
  
• Collaborate across teams, sharing knowledge and pushing for continuous improvement.
  
• Write clean, maintainable code and actively participate in code reviews.
  
• Communicate clearly and transparently with both your team and clients.
  
• Stay flexible and ready to adapt as projects and technologies evolve.
  

• Experience and skills you need to join us:

  • Excellent communication skills – you’re comfortable speaking with both technical and nontechnical stakeholders, giving and receiving feedback, and working transparently within a team.
    
  • Flexibility in project allocation – you’re open to working on different types of projects, from PoCs and MVPs to longer product builds, and can adapt to various life cycles and scopes.
    
  • Strong sense of ownership and accountability – you take full responsibility for your work, from understanding requirements to delivering clean, tested, and maintainable solutions.
    
  • Fluent in English and Polish – effective collaboration with both international clients and local team members is key.
    
  • Solid experience with TypeScript – you value type safety and write code that’s reliable, testable, and easy to maintain.
    
  • Proven experience building fullstack applications using our core stack:
  • • Backend: Node.js (TypeScript), GraphQL (Apollo or similar), PostgreSQL, Drizzle ORM (or willingness to learn)
    • Frontend: React with TypeScript, Next.js (App Router), TanStack libraries (React Query, Table, etc.)
    • • Ability to break down complex application logic into manageable components across backend and frontend layers.
      • Testing mindset – you write tests for your code and have experience with tools like Vitest and Playwright.
      • Familiarity with modern development workflows and tooling, including
        • Git & version control best practices
        • CICD pipelines
        • Docker
        • Working with REST and GraphQL APIs
        • • Agile, teamoriented mindset – you collaborate well, iterate quickly, and value continuous improvement.

          • It would be great if you also have:

            • Experience with rapid prototyping and building MVPs.
            • Skills in performance optimization – both backend and frontend.
            • Familiarity with monorepos (e.g. Turborepo, Nx).
            • Experience integrating AI APIs (e.g. chats, agents, RAG pipelines).
            • Use of AIpowered dev tools (e.g. Cursor, GitHub Copilot) in your workflow.

            • How we work:

              At Tooploox, you have the flexibility to choose your working hours and location. While we value remote work, we also believe in building relationships and invite you to join us in our Warsaw and Wrocław offices. Enjoy a relaxed atmosphere and try some “homemade” pizza from our office pizza oven. We love having pets in the office, so feel free to bring yours along.

              Join us and shape the future of AI while working the way you like!
