Full-Time Senior C++ Engineer

At Tracify GmbH, we redefine the landscape of analytics and tracking solutions. With innovation at our core, we empower businesses to leverage data, uncover insights, and unlock unparalleled growth.

As our Senior C++ Engineer, you will take ownership of critical backend systems, pushing the boundaries of performance, scalability, and functionality.

You will work on high-performance data pipelines, advanced bot frameworks, and ML-based tools, collaborating with cross-functional teams to deliver features that drive real business value.

• Extend and optimize our core data pipelines (AnalyticsCore) with advanced functionality and improved performance.
• Implement machine learning-based attribution models and custom user matching methods (e.g., clustering, graph-based approaches).
• Integrate new identifiers (e.g., device/browser fingerprinting) and additional data sources for comprehensive tracking.
• Build and maintain unit tests for robust, high-quality code coverage, including edge-case scenarios.
• Identify and resolve architectural bottlenecks, performance issues, and security vulnerabilities.
• Run performance evaluations using tools like Google Orbit to monitor and optimize system efficiency.
• Collaborate with backend, product, and data science teams to enable advanced functionality and data integrations.
• Develop inspection tools and documentation to support customer success and technical troubleshooting.
• Enhance and expand our bot framework (TracyBots) with advanced algorithms (e.g., dynamic bidding, predictive performance models).
• Develop new and advanced bots leveraging machine learning (e.g., reinforcement learning-based bots).
• Support the transition from legacy systems to the new AnalyticsCore infrastructure.
