Key Responsibilities:

• Lead the end-to-end architecture, design, development, and delivery of scalable, secure, and highly available AI-powered solutions.
• Define and evolve technical architecture for LLM applications, RAG pipelines, agentic AI workflows, and AI/ML platforms.
• Design and implement distributed, cloud-native solutions using AWS, Azure, and/or GCP.
• Drive best practices around scalability, availability, fault tolerance, observability, security, and cost optimization.
• Champion AI-assisted software development using tools such as GitHub Copilot, Cursor, Claude Code, and other agentic coding tools.
• Evaluate and integrate open-source frameworks, libraries, and platforms to develop sustainable and vendor-agnostic solutions.
• Provide hands-on technical leadership through coding, proof-of-concepts, prototypes, code reviews, and critical architectural decisions.
• Establish engineering standards covering security, performance, scalability, observability, accessibility, privacy, and responsible AI.
• Lead architecture reviews and provide guidance on technical trade-offs, build-vs-buy decisions, and platform standardization.
• Define and guide DevOps, SRE, and MLOps practices including CI/CD, Infrastructure as Code, model deployment, monitoring, and continuous evaluation.
• Mentor and coach senior engineers, technical leads, and architects.
• Collaborate with engineering, product, and solutions teams to align technical strategy with business objectives and product roadmaps.
• Stay current with emerging technologies in Generative AI, LLMs, agentic systems, cloud computing, and applied ML.

Required Qualifications:

• Bachelor's or Master's degree in Computer Science, Engineering, or a related field, or equivalent professional experience.
• 12+ years of professional software engineering experience.
• Minimum 3+ years of experience in a Principal Engineer, Staff Engineer, or Enterprise Architect role.
• Proven experience architecting and delivering large-scale, production-grade AI/ML or data-intensive solutions.
• Strong experience designing and operating highly available, distributed enterprise systems.
• Hands-on experience with LLM applications, RAG systems, vector databases, prompt engineering, fine-tuning, or agentic workflows.
