Responsibilities
Own the end-to-end agent architecture: agentic planning and execution loops, long-term memory, persona/voice, knowledge routing, and policy enforcement for compliant, on-brand conversations
Ship production systems that handle millions of conversations with rigorous SLOs, fallbacks, and canaries; design graceful degradation (e.g., human handoff) and safety guardrails (prompt-injection, jailbreak, PII redaction)
Lead voice agent initiatives: Drive the development of Uber's voice support agent-covering real-time speech recognition (ASR), text-to-speech, natural turn-taking (barge-in and endpointing), and reliable telephony/WebRTC integration. Ensure low-latency, high-quality interactions that remain robust even in noisy environments
Advance retrieval & reasoning: Build next-generation retrieval and reasoning pipelines, where the agent can search across different knowledge sources, apply policy-driven tools, and call structured workflows and ensure that responses are consistently grounded
Establish evals that matter: offline rubrics, simulated scenarios, safety tests, cost/latency tradeoff suites, and LLM-as-judge (with calibrated human review) wired into CI/CD and experiment platforms
Drive automation at scale: partner with Product/Design/Operations on coverage, policy alignment, localization, and rollout strategy to better customer experience and reduce cost per contact
Mentor/principal-lead multiple pods; set technical strategy and quality bars; coach senior engineers on agentic patterns, reliability, and experiment velocity
Qualification
Required
10+ years building production ML/AI systems; 4+ years leading complex ML initiatives end-to-end
Deep expertise in LLM-driven systems (inference optimization, prompt/program design, fine-tuning, distillation/LoRA, safety/guardrails, evals)
Strong software engineering in Python plus one of Go/Java/C++; hands-on with microservices, gRPC/HTTP, cloud infra, containers, CI/CD, and real-time telemetry/observability
Demonstrated ownership of high-availability services (SLO/SLA design, incident response, on-call leadership, postmortems)
Track record of shipping customer-facing intelligent experiences with measurable impact (A/B testing, metrics literacy)
Preferred
Voice agent background (ASR/TTS streaming, barge-in, endpointing, telephony, WebRTC) and conversational quality/NLP evaluation. Patterns seen in peer roles emphasize speech + dialog quality as core skills
Agentic architectures in production (planner/executor, memory, multi-step reasoning) and RAG over complex, policy-heavy knowledge bases
Experience building support automation for large consumer platforms (routing, policy codification, internal tooling, co-pilot/auto-resolve)
Multilingual NLU/NLG (code-switching, low-resource languages), hallucination mitigation, safety red-teaming, and privacy-by-design
Practical expertise balancing speed and reliability at scale: experiment frameworks, feature flags, canary/guarded rollouts, and clear kill-switches
