Hybrid/Remote

Ervaring

5+ years

Join us to build the future of construction technology

The construction industry shapes the skylines we admire and the infrastructure we rely on. Yet too many projects still fall behind schedule and over budget because critical information is trapped in outdated systems.

At Levvr, we believe there’s a better way. By moving from document-driven work to data-driven collaboration, we create a foundation where knowledge builds over time, turning every project into a stepping stone toward a smarter, more sustainable construction industry. This shift unlocks true collaboration for engineering teams, reduces waste, accelerates delivery, and ensures that billions in public and private funds are invested in future-proof infrastructure rather than lost to inefficiency.

When you join us, you’re not just writing code, you’re helping build the foundation for faster, smarter, and more sustainable construction worldwide.

We are looking for a software engineer with 5+ years of experience to join us on this exciting journey. This is a role within a fast growing SaaS scaleup, so if you like a dynamic working environment and learn new things then this is the challenge for you.

You will be responsible for:

• Lead the design and development of scalable web applications with React + TypeScript
• Take ownership of the frontend architecture, ensuring performance, maintainability, and reliability
• Collaborate with product, design, and backend teams to deliver features that solve real-world engineering problems
• Build and evolve our design system and component library for consistency and speed
• Write clean, tested, reusable code and champion frontend best practices
• Troubleshoot, debug, and proactively improve user experience
• Contribute to team growth by mentoring mid-level engineers and sharing knowledge

What we’re looking for:

• Bring 5+ years of professional experience in frontend development
• Are fluent in ReactJS (state management, hooks, patterns) and TypeScript
• Have solid experience with testing frameworks (e.g., Jest, React Testing Library, Cypress)
• Understand modern Git workflows and CI/CD practices
• Care deeply about code quality, performance, and accessibility
• Communicate clearly in English (B2+)
• Are curious, ask questions, and work independently while thriving in a fast-moving startup

Bonus if you have experience with:

• Data visualization libraries, GraphQL, or real-time collaboration features
• Building SaaS products in scale-up environments

Why levvr?

• Remote-first culture, with the option to join us at our Rotterdam HQ
• Two mid-year team trips with the whole crew to inspiring locations in Europe
• Personal development budget for training, coaching, or courses
• 25 paid holidays per year
• When based in NL: NS Business Card for public transport
• Top-notch equipment (laptop, monitor, setup of your choice)
