The Opportunity
We are seeking a technical Engineering Manager, Applied ML (Search & Recommendations) to lead our Search Retrieval, Ranking and Recommendations. You will be the architect of our "Discovery Engine," moving beyond keyword matching to deep semantic understanding of construction data. You will lead a team of Applied ML engineers to design and deploy state-of-the-art models leveraging LLMs, vector databases, and sophisticated re-ranking algorithms to transform how the industry procures materials.
What You Will Achieve and Key Responsibilities
AI Strategy & System Development
- Semantic Search & Ranking: Own the architecture for our hybrid search engine, blending keyword-based retrieval with dense vector embeddings to improve precision and recall.
- Recommendation Systems: Design and scale personalization algorithms that suggest products based on project specs, historical data, and cross-catalog compatibility.
- Model Fine-Tuning: Lead the fine-tuning of open-source and proprietary LLMs/encoders for specialized construction domain tasks, including NER and relationship extraction from complex documents.
- Vector Infrastructure: Architect and optimize our vector database strategy for high-concurrency retrieval and low-latency ranking.
Team Leadership & Product Lifecycle
- Mentorship: Lead, mentor, and grow a high-performing team of Machine Learning Engineers.
- Cross-functional Collaboration: Work closely with product managers, UX designers, and business leadership to integrate AI components into fully functional systems.
- Lifecycle Management: Participate in the complete product lifecycle from concept design to development, testing, and deployment.
Scalable Solutions
- Performance at Scale: Build products that handle large data volumes efficiently while remaining highly scalable for new clients.
- MLOps: Design end-to-end data and ML pipelines for seamless production integration and monitoring.
Research & Excellence
- R&D Leadership: Work with the leadership team on research efforts to explore cutting-edge technologies.
- Engineering Standards: Uphold a culture of excellence by maintaining high standards in code quality, innovation, and rigorous experimentation.
