Java Developer jobs in Canada

About Compactica Compactica is a software company based in St. John’s, Newfoundland and Labrador, dedicated to pioneering efficient and reliable solutions within the geotechnical and construction space. We have developed and launched a groundbreaking SaaS solution aimed at transforming compaction testing practices at large construction sites. Our technology promises not only to save significant time, money, and risk for our clients but also to enhance the reliability and validity of test results. We are redefining the compaction space.

Our system comprises:

• Field Gear Subsystems: Run on custom single-board computers with cellular connectivity, GPS, and accelerometers. These operate autonomously, unaffected by intermittent internet, to collect and process sensor data. New initiatives include integrating camera sensors for image processing.
• Cloud-Based Systems: Multi-tenant SaaS user interfaces and data services, hosted on bare-metal servers via a cloud provider, delivering near real-time insights.
• Operational Support Systems: Tools to manage clients, hardware, and system performance, with a strong emphasis on data quality and system monitoring.

We’re on the lookout for a talented Senior Software Developer to join our dynamic team. This is a unique opportunity to be at the forefront of developing and enhancing innovative projects that position Compactica as a leader in the industry. If you’re passionate about making a tangible impact and independently leading and innovating within our modular, high-performance platform, including new machine learning and AI-driven features, we’d love to hear from you.
