Job Description Summary:

As a Staff AI Engineer, you define and drive the architecture of AI and agentic systems across multiple teams and product domains. This is a senior individual-contributor leadership role: you influence high-impact architectural decisions, evolve the practices and standards for building agentic AI, and turn experimental AI capabilities into reliable production systems. You set direction for multi-agent orchestration, production RAG (hybrid search, re-ranking, and query routing), tool and MCP integration, and the evaluation and observability stack that keeps them dependable. You mentor senior engineers and represent AI engineering in cross-functional and strategic initiatives. A background in classical ML is an asset; the primary requirement is a proven track record of shipping production agentic AI.

KEY RESPONSIBILITIES

Define and drive technical direction for AI and agentic systems, and contribute to the AI platform roadmap across teams

Influence architecture decisions for compute, cloud, and AI infrastructure across teams

Lead the design of large-scale AI/LLM systems: inference platforms, APIs, and distributed architectures

Architect production multi-agent systems end-to-end: orchestration, state management, tool integration, and failure handling

Define and drive best practices and standards for AI/LLM systems across teams (agent design, evaluation, observability, reliability)

Lead complex production debugging and incident response across teams, and harden the resulting fixes into platform guardrails

Mentor senior engineers and emerging technical leaders, raising the engineering bar

Lead technical design reviews and architecture decision records (ADRs) for critical AI infrastructure

Contribute to capacity planning and cost optimization strategies for AI/LLM infrastructure

GENAI / AGENTIC AI CAPABILITIES

Define and drive vector database and RAG architecture decisions across systems and teams: structured RAG, hybrid search (dense + sparse + keyword), re-ranking, and query routing

Lead multi-agent platform architecture decisions: runtime selection, orchestration patterns, and enterprise integration strategy

Set the technical direction for MCP (Model Context Protocol) adoption and agent runtime infrastructure

Shape agent infrastructure adoption: evaluate and standardize frameworks, tooling, and deployment patterns for agentic AI

Architect evaluation infrastructure for non-deterministic LLM systems: synthetic golden-set generation, hierarchical weighted scoring (component, composite, and system-level F1), bootstrap confidence intervals, and paired A/B comparison, treating a change as real only when it is both statistically significant and clears a minimum effect size

Gate deployments on eval results: tiered regression thresholds (hard-gate vs monitor components) wired into CI so a measurable quality regression blocks the release, with observability via tracing across multi-step chains and tool calls and drift detection on LLM inputs and outputs

Drive LLM cost optimization at scale: model routing, caching, batching, token budget management, and provider cost analysis

REQUIRED SKILLS & QUALIFICATIONS

Master’s or Ph.D. degree in Computer Science, Software Engineering, or a related field.

10+ years of professional experience in ML/AI or software engineering, including 4+ years in senior or staff-level roles with production system ownership

Demonstrated engineering leadership, including driving technical strategy and influencing cross-team decisions

Expertise in platform and distributed-systems architecture at scale: model serving, APIs, data platforms, and AI/LLM infrastructure

Hands-on experience architecting and operating production agentic AI or LLM systems (multi-agent workflows, production RAG, tool and MCP integration)

Deep understanding of embedding models, retrieval algorithms, and vector database internals

Strong production debugging, reliability, and incident-response skills

Experience building rigorous evaluation for non-deterministic AI systems, including statistical methods (such as bootstrap confidence intervals and minimum effect-size thresholds) to separate genuine quality changes from run-to-run model variance

Cost-awareness for cloud AI/LLM workloads: capacity planning and cost optimization

Proven mentorship of mid-level and senior engineers

Strong communication skills for executive and cross-functional audiences

PREFERRED QUALIFICATIONS (NICE TO HAVE)

Experience in Healthcare, FinTech, or other regulated industries

Experience building AI/LLM systems or platform components from the ground up

Defined best practices for AI-assisted development (Claude Code): code quality standards, review, and responsible usage across teams

Track record of conference talks, published papers, or significant open-source contributions

Experience with GPU-accelerated inference and model serving optimization

Familiarity with workflow orchestration and streaming architectures for real-time AI
