Accountabilities: Own the overall architecture and technical vision for AI-powered, user-facing applications built with Python, React, and Generative AI.

Translate client business objectives, functional requirements, and technical constraints into elegant, scalable, and durable technical designs.

Design scalable, secure, and cost-efficient backend platforms supporting LLM inference, RAG pipelines, and agent-based orchestration.

Define frontend architecture and AI-native UX patterns for conversational interfaces, copilots, intelligent dashboards, and other AI-powered experiences.

Lead the architecture and implementation of complex GenAI workflows combining LLMs, tools, APIs, structured data, and user context.

Establish engineering standards and best practices covering prompt engineering, model integration, evaluation, observability, and AI-assisted development.

Drive GenAI platformization by creating reusable components, SDKs, frameworks, and architectural patterns that can be leveraged across multiple teams and products.

Partner with Product, Design, Data, Engineering, and business leaders to translate strategic objectives into scalable technical solutions.

Review critical architectures, technical designs, and codebases, providing guidance on extensibility, scalability, security, design patterns, UX, and non-functional requirements.

Define technical strategies and influence architecture decisions across teams, pods, and major initiatives.

Lead technical discovery, solutioning, proof-of-concept activities, and client or executive-facing technical workshops when required.

Ensure enterprise AI solutions meet security, privacy, compliance, governance, and responsible AI requirements.

Define guidelines, benchmarks, and standards for non-functional requirements throughout project implementation.

Produce and review architecture and high-level design documentation, clearly communicating technical decisions and implementation guidance to development teams.

Evaluate alternative technical solutions and select approaches that best balance business requirements, scalability, performance, security, and cost.

Resolve complex technical issues through systematic root-cause analysis and clearly communicate and justify architectural decisions.

Use AI-assisted development tools such as GitHub Copilot or Claude Code to accelerate delivery while maintaining production-grade engineering standards.

Requirements

11+ years of total professional experience, including 10+ years in software engineering.
