What You'll Work On

Your projects may include:
Integrating data from operational and business systems.
Building centralized data pipelines and reporting infrastructure.
Automating manual reporting processes.
Creating reliable datasets for business intelligence.
Improving data quality and accessibility.
Supporting operational dashboards and analytics.

We're looking for a practical, curious, and hands-on Data Engineer who enjoys solving real business problems with technology.

You don't need to have experience in the demolition industry. What matters most is your ability to understand complex data problems, build reliable systems, communicate effectively, and take ownership of your work.
