Senior Software Engineer

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 Yet too many projects still fall behind schedule and over budget because critical information is trapped in outdated systems.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.
