RoleAs a Senior AI Engineer focused on CreditAI, our flagship GenAI product, you will own complex technical problems across the full AI stack designing distributed systems, orchestrating multi-agent workflows, and ensuring production reliability at scale. Responsibilities Design and implement multi-agent and agentic orchestration frameworks using agent SDKs such as the Claude Agent SDK, Google ADK, or AWS AgentCore, incorporating tools, external data sources, memory, and state management Build and maintain MCP servers and integrations to extend AI system capabilities with structured tool use and external context Build and optimize RAG pipelines including embedding strategies, vector database, retrieval quality tuning, and cost-aware ingestion design Integrate with managed LLM services across cloud providers to support diverse deployment and cost optimization strategies. Fine-tune, optimize, and deploy open-source deep learning models for production use cases, leveraging GPU infrastructure for training and inference Apply systems thinking to design and optimize AI and LLM systems, balancing quality, scalability, latency, cost, and operational complexity, while implementing efficiency improvements using model selection, prompt design, batching, caching, and retrieval strategies. Design and implement automated evaluation frameworks to assess LLM system quality, accuracy, and performance across production workloads Apply reinforcement learning techniques (e.g., RLHF, RLAIF) to improve model alignment and task-specific performance Architect and manage high-throughput, real-time data pipelines using Kafka Design, deploy, and scale production AI services on AWS (Batch, Lambda, ECS, S3, etc), applying modern containerization, CI/CD, and infrastructure-as-code practices Implement comprehensive observability frameworks using Datadog tracking token usage, pipeline latency, error rates, consumer lag, and model performance with actionable alerting Identify and resolve production bottlenecks across distributed systems, including database query optimization, consumer scaling, and LLM throughput tuning Apply strong problem-solving and critical thinking skills to break down complex, ambiguous requirements into clear, implementable technical components and system designs. Conduct code reviews; contribute to team standards around reliability, testing, and operational excellence Communicate progress, trade-offs, and outcomes to relevant stakeholders. Continuously learn and adapt to advancements in NLP and Generative AI to ensure solutions remain innovative and effective. Requirements Bachelor's or Master's degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience). 5+ years of experience as an AI Engineer, Machine Learning Engineer, or applied AI practitioner, with a strong foundation in computer science and algorithms. Deep Python expertise with a track record of shipping production systems at scale; strong software engineering practices including clea
