Provide technical leadership and mentorship to engineering teams while collaborating with architects, product managers, and UX designers to create innovative AI solutions that address complex customer challenges.

▪ Lead the design, development, and deployment of AI-driven features. Drive end-to-end ownership— from feasibility analysis and design specifications to execution and release—while ensuring quick iterations based on customer feedback in a fast-paced Agile environment.

▪ Spearhead technical design meetings and produce detailed design documents that outline scalable, secure, and robust AI architectures.

▪ Ensure that the solutions are aligned with long-term product strategy and technical roadmaps.

▪ Implement and optimize LLMs for specific use cases, including fine-tuning models, deploying pre trained models, and evaluating their performance.

▪ Develop AI agents powered by RAG systems, integrating external knowledge sources to improve the accuracy and relevance of generated content.

▪ Design, implement, and optimize vector databases (e.g., FAISS, Pinecone, Weaviate) for efficient and scalable vector search, and work on various vector indexing algorithms.

▪ Create sophisticated prompts and fine-tune them to improve the performance of LLMs in generating precise and contextually relevant responses.

▪ Utilize evaluation frameworks and metrics (e.g., Evals) to assess and improve the performance of generative models and AI systems.

▪ Work with data scientists, engineers, and product teams to integrate AI-driven capabilities into customer-facing products and internal tools.

▪ Stay up to date with the latest research and trends in LLMs, RAG, and generative AI technologies to drive innovation in the company’s offerings.

▪ Continuously monitor and optimize models to improve their performance, scalability, and cost efficiency.

We'd Love for You to Have: ▪ 1 to 2 years of experience and strong understanding of LLMs and their underlying principles — transformer architecture, attention mechanisms, and hyperparameter tuning.

▪ Proven experience designing and building AI agents, including multi-agent orchestration, tool-use patterns, multi-step planning, and agent memory architectures (short-term and long-term).

▪ Hands-on experience with agentic frameworks such as LangGraph, CrewAI, or AutoGen, and familiarity with RAG pipelines that integrate external knowledge sources (documents, databases, APIs).

▪ In-depth knowledge of vector databases and indexing algorithms; practical experience with FAISS, Pinecone, Weaviate, or Milvus.

▪ Experience with agent observability, tracing, and guardrails — tools like Langfuse or equivalent — to ensure reliability, safety, and debuggability of agentic systems.

▪ Proficiency in prompt engineering — crafting, iterating, and optimizing complex prompts for context sensitive, domain-specific LLM outputs.

▪ Familiarity with Evals and other performance evaluation tools for measuring model quality, relevance, and efficiency.

▪ Proficiency in Python and experience with machine learning libraries such as TensorFlow, PyTorch, and Hugging Face Transformers.

▪ Experience with data preprocessing, vectorization, and handling large-scale datasets.

▪ Ability to present complex technical ideas and results to both technical and non-technical stakeholders.

Experience in building AI agents using graph-based architectures, including knowledge graph embeddings and graph neural networks (GNNs).

▪ Experience with training small base models using custom data, including data collection, pre processing, and fine-tuning models to specific domains or tasks.

▪ Familiarity with deploying AI models on cloud platforms (AWS, GCP, Azure) and containerization technologies (Docker, Kubernetes).

▪ Familiarity with programmatic advertising, RTB, or ad auction mechanics.

▪ Knowledge of MCP (Model Context Protocol) or similar tool-integration standards

▪ Publication or contributions to research in AI, LLMs, or related fields.
