Job Description

We are looking for a Sr. Staff Engineer to join our team.

Key Responsibilities

• Design and architect enterprise-wide Generative AI solutions, including reference architectures, integration patterns, and technical standards.
• Design, build, and maintain an enterprise AI gateway to centralize access, governance, and monitoring of AI model consumption across the organization.
• Develop and implement intelligent routing techniques to direct requests across multiple large language models (LLMs) and AI providers based on cost, latency, accuracy, and availability requirements.
• Evaluate and integrate local/on-premises models as alternatives to third-party hosted models, with a focus on reducing operational costs.
• Establish frameworks for measuring and demonstrating cost savings achieved through model selection, routing optimization, and infrastructure decisions.
• Collaborate with engineering, security, and compliance stakeholders to ensure AI architecture adheres to organizational governance and regulatory requirements.
• Define best practices for prompt orchestration, caching strategies, and fallback mechanisms within the AI gateway.
• Provide technical leadership and mentorship to engineering teams adopting Generative AI capabilities.
• Provide mentorship and lead a team of AI/ML engineers.

Required Qualifications

• Demonstrated experience architecting Generative AI solutions at an enterprise scale.
• Research and integrate cutting-edge LLMs and autonomous AI agent architecture into development processes.
• Develop RAG pipelines that enhance AI‘s ability to retrieve relevant knowledge and generate context‑aware responses.
• Build and optimize agentic AI systems that can interact with APIs, databases, and development environments (such as LangChain, OpenAI APIs, etc.).
• Fine‑tune LLMs (GPT, Llama, Mistral, Claude, Gemini etc.) for domain‑specific applications.
• Optimize models for local inference through quantization, pruning, and distillation.
• Deploy models on‑prem or at the edge using frameworks such as PyTorch, TensorRT, ONNX, vLLM, or llama.cpp.
• Build and maintain training and inference pipelines for reproducibility and scalability.
• Integrate locally deployed models into production systems via APIs and internal services.
• Monitor model performance, drift, latency, and resource utilization in production.
• Optimize retrieval mechanisms to enhance response accuracy, grounding AI outputs in real‑world data.
• Hands‑on experience designing and implementing AI gateway solutions and model routing techniques.
• Proven track record of achieving measurable cost savings through the use of local/open‑source models or alternative optimization techniques.
• Strong understanding of LLM provider ecosystems, API integration patterns, and multi‑model orchestration.
• Experience with cloud infrastructure and enterprise architecture frameworks.
• Solid grasp of AI governance, security, and compliance considerations in enterprise environments.
• Excellent communication skills, with the ability to present technical concepts to both technical and non‑technical stakeholders.
• Architect and deploy scalable AI models and retrieval pipelines using cloud‑based MLOps pipelines (AWS/GCP/Azure, Docker, Kubernetes).
• Optimize LLMs for real‑time AI inferencing, ensuring low latency and high‑performance AI solutions.

Education

Master’s or Ph.D. in Computer Science, AI, Machine Learning, or a related field.

Experience

5+ years of experience in AI and machine learning, with at least 2 years of experience working on LLMs, code generation, RAG, or AI‑powered automation.
