    About the Position

    Introduction

    Are you looking for a significant challenge at a startup with a clear vision in the Web3 space? Join a rapidly growing company building a platform for decentralized identification, allowing users to authenticate, share, and verify their identity securely using a crypto wallet, without sacrificing direct ownership. This company is a pioneer in the 'verified internet' and aims to launch a fully functional product by the end of the year.

    As a startup, they offer immense flexibility and freedom. They are looking for someone with a strong vision for optimal software architecture and the ability to bring those ideas to life. You'll be working with a tech stack that includes React (TypeScript) for the frontend, NodeJS for the backend, PostgreSQL as the database, and Google Cloud for hosting. They operate in a Linux environment with a robust CI/CD pipeline built with GitHub Actions. While they have an active Blockchain/Web3-Development team, direct experience with Solidity or other blockchain-specific technologies is a plus but not a strict requirement for this role.

    Responsibilities

    • Design and implement scalable software architectures.
    • Develop and maintain the frontend using React (TypeScript).
    • Build and manage the backend using NodeJS.
    • Work with relational databases, specifically PostgreSQL.
    • Utilize Google Cloud for deploying and managing applications.
    • Contribute to the CI/CD pipeline using GitHub Actions.
    • Collaborate with the Blockchain/Web3-Development team.
    • Play a significant role in expanding the development team, both locally and internationally.

    Requirements

    • 5+ years of Fullstack Development experience.
    • Strong experience with React (TypeScript) and NodeJS.
    • Experience with relational databases like PostgreSQL.
    • Experience with cloud solutions like Google Cloud.
    • Proven ability to build scalable software architectures.
    • Affinity with blockchain / Web3 (experience is a plus).
    • Dutch language skills preferred (working knowledge required for this role based in the Netherlands).

    Benefits

    • Competitive salary: €4,000 - €6,000 per month.
    • 25 holiday days.
    • Company laptop (MacBook/Windows).
    • Hybrid work model (2-3 days in the office).
    • Modern office located in Utrecht City Center.
    • Significant room for professional growth and exploring new technologies.
    • Opportunity to work in an innovative startup within an exciting field.
    • Active promotion of attending conferences, organizing hackathons, and courses.
    • Frequent team events (dinners, board game nights, other fun activities).
