Senior Software Developer

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.

Tech Stack

• Languages: C# (ASP.NET, Entity Framework), TypeScript (Angular), C (microcontroller code), Python (for ML/AI development).
• Tools: Visual Studio (IDE), GitHub (source control), ML frameworks (e.g., TensorFlow, PyTorch).

Techniques:

• Custom code generation for consistent, reliable logic from database to UI.
• Asynchronous, multi-threaded, and parallel processing for high-performance data handling.
• Queueing patterns and HTTP/WebSocket APIs for reliable, high-frequency data transmission.
• Machine learning models for image processing and integration with sensor data (GPS, accelerometers).
• Design patterns inspired by large-scale enterprise systems (healthcare, manufacturing, finance, CRM).

Infrastructure: .NET and Angular for cross-platform compatibility, bare-metal cloud hosting.
