Job Description
AI Engineer — Agentic AI, RAG & Low-Latency Voice Systems
nMobiloitte Technologies (I) Pvt. Ltd. | New Delhi (on-site / hybrid) | Full time | 5+ years
nCompensation: No ceiling for the right candidate.
n

nTwo things decide this role: how well you handle latency, and how far past basic RAG you can build.
n

nMobiloitte builds production AI for enterprise clients across India, the US, UK, UAE, Singapore and South Africa. We're hiring a senior AI Engineer to own our agentic AI, retrieval and voice stack — systems that go live, carry real call volume, and stay up.
n

n1. LATENCY IS THE JOB, NOT A DETAIL
n

nOur voice bots handle inbound and outbound calls where a 400ms difference decides whether the conversation feels human. We need someone who treats latency as an engineering discipline:
n

n- Owns end-to-end voice latency from user speech to first token of bot audio — and can quote the numbers they achieved
n- Profiles and attacks each hop: STT, retrieval, inference, TTS, network
n- Streaming responses, speculative/partial generation,



response chunking to shorten time-to-first-audio
n- Barge-in and interruption handling that actually works mid-sentence
n- Model caching, warm pools, batching, concurrency control under real call load
n- Knows when the fix is architectural, not a bigger GPU
n

nIf you can't tell us what your p95 latency was and what you did to bring it down, this isn't the role.
n

n2. AGENTIC AI — BEYOND BASIC RAG
n

nSingle-shot retrieve-and-answer is table stakes. We're building systems that plan, act and self-correct:
n

n- Agent orchestration — LangGraph, CrewAI, AutoGen, OpenAI Agents SDK, or your own framework (we care that you've built it, not which one)
n- Tool and function calling, API/DB actions, structured outputs
n- Multi-step reasoning, task decomposition, planning loops with retry and fallback
n- Multi-agent patterns — routing, supervisor/worker, handoffs
n- Conversation and long-term memory ma
