AI Tech Lead - Staff Machine Learning Engineer

Sumo Logic, Inc. empowers modern digital businesses by offering a cloud-native applications analytics platform. They are seeking an AI Tech Lead to design and deliver advanced AI systems for their Security Operations Center, focusing on the development of scalable multi-agent architectures for real-time data processing and security operations.

Responsibilities:

• Lead and partner with fellow leadership members and teams on technical evaluation and adoption of cutting-edge agentic AI platforms, including Anthropic (Claude), LangChain/LangGraph, AWS Bedrock, and other emerging agent frameworks
• Architect, prototype, and productionize multi-agent AI systems for Agentic SOC use cases, including detection, triage, investigation, and response workflows
• Own the design of core agent architecture components, including planning, execution, tool orchestration, memory, context engineering, and long-running agent workflows
• Lead AI agent evaluation systems, including offline and online evaluation pipelines, golden datasets, synthetic data generation, human- and LLM-based judging, and continuous quality monitoring
• Drive LLM fine-tuning and alignment efforts to improve domain-specific reasoning, accuracy, and reliability for security and observability use cases
• Design scalable LLMOps and AI agent infrastructure, including inference routing, latency optimization, cost control, and production observability for agent systems
• Partner with product, security, and data platform leadership and teams to deliver end-to-end AI agent capabilities from prototype to customer-facing production systems
• Lead and partner on technical direction and mentorship for AI engineers working on agentic AI and LLM systems
• Define and implement best practices for AI safety, reliability, evaluation, and monitoring in production agentic systems
• Operate as a senior technical owner in ambiguous problem spaces—setting technical direction, breaking down complex problems, and driving delivery across teams

Requirements:

• B.Tech, M.Tech, or Ph.D. in Computer Science, Machine Learning, Data Science, or a related technical field
• 5+ years of hands-on industry experience building, operating, and leading production ML/AI systems, with demonstrated technical leadership and ownership
• Strong foundation in machine learning, distributed systems, data pipelines, and large-scale system design
• Deep industry understanding of LLMs, prompt engineering, context engineering, agentic AI design patterns, and reasoning workflows
• Strong proficiency in Python and modern ML/AI ecosystems
• Experience designing and operating evaluation frameworks for ML/LLM systems (offline + online)
• Proven ability to lead complex technical initiatives across teams and influence architecture decisions
• Excellent communication skills and ability to translate complex AI systems into business impact
• Hands-on experience building and scaling agentic AI systems or multi-agent architectures in production
• Experience with modern agent frameworks such as LangGraph, LangChain, CrewAI, or similar
• Experience with major foundation model platforms such as Anthropic, OpenAI, AWS Bedrock, or Vertex AI
• Experience with LLM fine-tuning pipelines (SFT, RLHF/RLAIF, preference learning, domain adaptation)
• Strong background in LLMOps, including inference optimization, latency/cost management, observability, and production monitoring
• Experience with ML infrastructure and tooling such as PyTorch, MLflow, Airflow, Docker, Kubernetes, and cloud platforms (AWS/GCP/Azure)
• Experience applying AI/ML to security, observability, or large-scale log/telemetry data is a strong plus
