This role requires both deep technical expertise and the ability to guide teams in building reliable, secure, and high-performing AI systems.

Key Responsibilities

Agentic AI & GenAI Architecture

• Lead the design and implementation of advanced agentic architectures, including multi-agent orchestration, tool usage, planning, memory management, and self-reflection patterns using platforms such as Google ADK.
• Define and standardize RAG architectures, including retrieval strategies, context engineering, hybrid search, re-ranking, and optimization of latency, accuracy, and cost.
• Establish prompt engineering standards and governance, ensuring consistency, reliability, and scalability across use cases.
• Design and implement evaluation frameworks to measure model performance (hallucination rates, precision/recall, response quality).
• Define observability strategies for multi-agent systems, including tracing, debugging, and performance monitoring.

Backend & Systems Engineering Leadership

• Architect and oversee development of scalable, asynchronous backend systems and APIs using FastAPI or similar frameworks.
• Define best practices for system integration, enabling AI agents to interact securely with enterprise systems, APIs, and external tools.
• Ensure high standards in software design, modularity, performance, and reliability across services.

Cloud Architecture & MLOps

• Lead the design and deployment of cloud-native AI solutions on GCP, ensuring scalability, resilience, and cost optimization.
• Define containerization and orchestration strategies using Docker and Kubernetes (GKE).
• Establish and improve CI/CD pipelines, testing frameworks, and release processes for AI systems.
• Oversee database architecture, including vector search (pgvector) and relational data management.

Technical Leadership & Collaboration

• Provide technical leadership and mentorship to engineers, promoting best practices in AI/ML and software engineering.
• Collaborate with product, data, and engineering teams to translate business needs into scalable AI solutions.
• Drive architecture decisions, code reviews, and technical standards across projects.
• Ensure alignment with security, privacy, and governance standards, especially for GenAI applications.

Required Qualifications

• 5+ years of software engineering experience, with 2–3+ years building and deploying production-grade AI/LLM systems.
• Expert-level proficiency in Python, including asynchronous programming (AsyncIO).
• Strong experience designing and implementing RAG pipelines, vector search, and GenAI systems.
• Proven experience architecting multi-agent systems or complex AI workflows.
• Deep experience with FastAPI (or similar frameworks) for building scalable backend services.
• Strong knowledge of PostgreSQL and vector databases (pgvector or equivalent).
• Hands-on experience with GCP, including deploying and managing applications in cloud-native environments.
• Strong experience with Docker, Kubernetes (GKE), and CI/CD pipelines.
• Solid understanding of distributed systems, API design, and software architecture principles.
• Experience implementing evaluation, monitoring, and observability for AI systems.
• Strong communication skills and ability to work in cross-functional teams.
• English proficiency – B2+/C1 preferred.

Preferred Qualifications (Nice-to-Haves)

• Hands-on experience with Google ADK (Agent Development Kit) or similar agent orchestration frameworks.
• Experience with real-time systems, including streaming responses (WebSockets, SSE).
• Familiarity with additional GenAI frameworks (e.g., LangChain, LlamaIndex) for broader architectural perspectives.
• Experience implementing security, guardrails, and PII protection in AI systems.
• Background in scaling AI systems in enterprise environments.
• Experience leading or contributing to architecture design reviews and technical roadmaps.
