• Design, build, and orchestrate Agentic AI systems, including multi-agent workflows, tool integrations, state management, observability, and real-time agent serving
• Partner cross-functionally with data architects, product management, and engineering to automate complex analytics, anomaly detection, and threat triage
• Lead the technical implementation, debugging, and end-to-end monitoring rollout plans for resilient, production-grade agentic frameworks

Who You Are (Success Profile)

• You thrive in ambiguity and view uncharted challenges as opportunities to build meaningful, scalable platform architecture.
• You operate with true ownership, balancing high-level strategic planning with deep, hands-on technical execution.
• You run toward complex problems with a bias for action, delivering measurable impact across data and AI systems.
• You are a high-trust partner who practices transparent communication, constructive candor, and shared accountability to elevate team performance.
• You embody a continuous learning mindset, proactively incorporating emerging AI frameworks, architectures, and engineering best practices.

What We’re Looking for (Minimum Qualifications)

• Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
• 3+ years of hands-on software engineering experience in Java and Spring Boot within large-scale, data-intensive environments
• Hands-on experience with Redis caching, partition-aware query patterns, and high-performance querying on platforms such as Azure Data Explorer (ADX/Kusto) or Google BigQuery
• Proven experience building and operating LLM- or agent-based architectures, including multi-agent orchestration, agent-to-agent communication, and autonomous decision-making workflows
• Deep expertise in distributed systems architecture and major public cloud platforms including Azure, GCP, or AWS

What Will Make You Stand Out (Preferred Qualifications)

• Experience designing and optimizing autonomous AI agents with advanced reasoning, planning, and tool-use capabilities to automate complex network analytics and threat triage
• Proven track record of designing, building, and shipping production applications processing billions of events across big data, AI, and distributed systems
