We are looking for a Senior AI Engineer to design, build, and deploy production-grade AI applications. The role requires strong software engineering fundamentals combined with hands-on experience in LLM applications, RAG, agentic systems, AI evaluation, and production AI systems.
The ideal candidate can take AI solutions from prototype to reliable production systems, make sound technical trade-offs, and contribute to the technical direction of the AI engineering team.
I. What You’ll Do
- Design and develop production-grade LLM-powered applications and AI services.
- Build and optimize RAG and data-grounding solutions, including vector search, hybrid retrieval, reranking, knowledge graphs, and structured data retrieval.
- Design and implement agentic systems and workflows, including tool calling, multi-step reasoning, memory, context management, and agent orchestration.
- Develop evaluation frameworks and regression testing for AI systems, using deterministic evaluations, LLM-as-a-judge, and human-in-the-loop approaches where appropriate.
- Analyze model outputs, traces, and failure cases to drive evaluation-driven development and continuous improvement.
- Design AI systems for production reliability, scalability, security, observability, cost, and latency.
- Implement monitoring and observability for AI applications, including model performance, latency, cost, failures, and potential security risks.
- Select and evaluate appropriate LLM/model architectures and AI techniques based on business and technical requirements.
- Apply machine learning and deep learning fundamentals when developing or integrating AI/ML solutions.
- Collaborate with Product, Data, Software Engineering, and other stakeholders to translate business requirements into scalable AI solutions.
