Summary

The Associate Principal, AI Engineer is a senior technical leader who partners with Principal Architects, business stakeholders, and engineering teams to translate enterprise strategy into scalable, AI-enabled technology solutions. This role blends deep hands-on technical depth across full-stack engineering, cloud platforms, and modern AI architectures with the leadership presence needed to influence cross-functional teams and shape long-range technology direction.

The successful candidate will architect production-grade systems that integrate Generative AI, agentic workflows, and RAG-based retrieval into core enterprise applications, while mentoring engineering teams and establishing the patterns, guardrails, and platforms that allow AI to scale responsibly across the organization.

Key Responsibilities

Architecture and Technical Strategy

• Define reference architectures, design patterns, and platform standards for AI-enabled enterprise applications spanning web, mobile, and backend services.
• Partner with the Principal Architect to develop multi-year technology roadmaps that align cloud, data, AI, and application strategy with business objectives.
• Evaluate emerging technologies (foundation models, agentic frameworks, vector databases, MLOps tooling) and translate them into actionable adoption plans.
• Lead architectural reviews, ensuring system designs meet requirements for scalability, security, performance, observability, and total cost of ownership.

AI and Generative AI Engineering

• Architect Generative AI solutions including RAG systems, multi-agent workflows, conversational interfaces, and domain-specific fine-tuned models.
• Design responsible AI frameworks covering prompt engineering standards, evaluation pipelines, model governance, and content safety controls.
• Establish MLOps and LLMOps practices for model deployment, monitoring, drift detection, and continuous improvement.
• Integrate LLM providers (OpenAI, Anthropic, Google) and orchestration frameworks (LangChain, LangGraph) into production systems with appropriate fallback and cost controls.

Cloud and Platform Engineering

• Design cloud-native solutions on Google Cloud Platform, Azure, or AWS, leveraging managed AI services (Vertex AI, AlloyDB, Cloud Functions, equivalent services).
• Architect CI/CD pipelines, infrastructure-as-code, and platform automation that accelerate engineering velocity without compromising reliability.
• Define and enforce standards for containerization, microservices, API design, and event-driven architectures.

Leadership and Delivery

• Provide technical leadership to engineering teams of 15 to 30 engineers, including UI developers, backend engineers, ML engineers, and platform specialists.
• Mentor senior engineers and tech leads, growing the next generation of architects within the organization.
• Partner with product, design, and business stakeholders to scope initiatives, manage trade-offs, and deliver measurable business outcomes.
• Represent the architecture function in executive forums, vendor evaluations, and strategic planning sessions.

Required Qualifications

• 15 or more years of progressive experience in software engineering, with at least 5 years in architecture or senior technical leadership roles.
