ORIL is seeking a highly skilled Senior AI/ML Engineer to architect and scale our mission-critical, AI-driven data platform. At the core of our engineering culture is a steadfast commitment to performance, reliability, and uncompromising data integrity. The ideal candidate is an autonomous problem-solver who thrives in an agile environment, takes end-to-end ownership of complex systems, and pairs a bias for action with a dedication to robust, stable deployments.
Project:
Our client is a US-based innovator providing a centralized data platform for multi-family real estate. The product uses BI and AI analytics to help operators optimize marketing spend and operational efficiency. A core AI feature of this platform is an intelligent chatbot designed to help users seamlessly manage workflows, query data, and surface actionable insights.
What are we looking for?
- 5+ years of experience building and owning production-grade backend and ML systems in Python;
- Proven experience designing and deploying complex, multi-step LLM workflows and conversational agents (chatbots) using frameworks like LangChain or LangGraph;
- Deep understanding of RAG (Retrieval-Augmented Generation) pipelines: from chunking and embedding strategies to retrieval optimization and prompt engineering;
- Experience with "Text-to-SQL" or translating natural language into complex data queries, as the chatbot will interact heavily with BI analytics;
- Experience with LLM observability, tracing, and evaluation frameworks (e.g., Langfuse, Braintrust, Arize Phoenix, Ragas, or DeepEval);
- Experience with systematic prompt lifecycle management, versioning, and algorithmic optimization (e.g., DSPy);
- Experience profiling and minimizing time-to-first-token (TTFT) and overall response latency for real-time conversational agents;
- Strong analytical skills with the ability to explore datasets, identify patterns, measure outcomes, and derive actionable insights;
- Familiar with data cleaning and normalization techniques to ensure accurate, consistent, and reliable data for analysis and AI-driven applications;
- Curious about how multi-family real estate works and motivated to understand the key metrics behind the business (marketing spend, operational efficiency etc.) to better tune AI outputs;
- English level: Upper-Intermediate (B2+).
What will you do?
- Design, develop, and own the core AI architecture powering the platform's intelligent chatbot and automated BI insights;
- Build and refine advanced RAG pipelines to ensure the chatbot surfaces accurate;
- Develop robust AI agents capable of managing platform processes and executing complex operational tasks on behalf of the user;
- Set up and maintain automated CI/CD gates that run LLM evals and integration tests;
- Maintain a high shipping tempo, continuously iterating on chatbot features based on user feedback and internal telemetry;
- Diagnose and fix complex issues in the AI pipeline using advanced tracing and observability tools;
- Work closely with data engineers and product managers to refine the technical roadmap and ensure the AI seamlessly integrates with the broader BI platform.
