About The Position

We are hiring a hands‑on AI Engineering leader to design and scale TRANZACT’s next‑generation Conversational & Composable AI stack across three pillars: Voice AI, Agentic AI, and AI‑driven Analytics. You will own systems‑level architecture and delivery—from low‑latency speech and telephony to agentic orchestration and governed analytics—turning unique data assets into durable business outcomes. This role combines strategic ownership with sleeves‑rolled‑up execution.

Requirements

• 7+ years in applied ML/AI or realtime distributed systems; 3+ years leading production LLM/voice solutions.
• Proven experience building realtime voice agents (WebRTC‑class streaming or equivalent) with measurable business impact.
• Hands‑on fine‑tuning experience (parameter‑efficient and, when needed, full‑parameter): data curation, SFT, preference/reward optimization, safety tuning, and evals.
• Production RAG for conversational use cases (hybrid retrieval, reranking, caching, grounding/citation) with strong observability.
• Strong engineering in Python and PyTorch; exposure to TypeScript or similar is a plus.
• Bachelor’s degree in Computer Science required; Master’s in CS (AI focus) preferred.
• Experience with governed data/ML platforms (catalog, registry, lineage) and secure deployment patterns.
• Track record of mentoring and uplifting teams; effective communicator with stakeholders across technical and non‑technical domains.

Nice To Haves

• Vector/search platforms and rerankers; hybrid lexical + dense retrieval; multilingual/domain adapters.
• LLM traces/observability tooling; model registries; dataset versioning and approval gates.
• Safety tooling (policy classifiers, redaction/PII handling) and progressive rollout (shadow/canary/feature flags).
• Streaming RAG for Voice AI (incremental retrieval, early‑token generation/TTFB optimization, barge‑in‑friendly generation).
• Telephony/contact‑center systems and marketing analytics experience.

Responsibilities

• Define and evolve the end‑to‑end Conversational AI platform: realtime ASR → agentic reasoning → TTS with sub‑second turn‑taking and production‑grade reliability.
• Establish scalable multi‑agent patterns (task routing, tool use, memory, human‑in‑the‑loop) and standard SDKs/templates to accelerate team adoption.
• Stand up enterprise‑grade Conversational RAG: hybrid retrieval, grounding/citation, freshness, and streaming context for voice/chat.
• Implement Responsible AI controls, observability, and governance (catalogs, lineage, model registry, policy enforcement) across the stack.
• Uplift the broader Engineering org by sharing reusable components, golden paths, and best practices; reduce vendor dependency via self‑service capabilities.
• Serve as Lead Engineer/Producer for at least one critical initiative per quarter, driving requirements → architecture → implementation → launch → post‑launch learning.
• Architect low‑latency streaming pipelines and telephony/queue integrations (SIP/IVR/contact center) to support overflow, warm transfer, and compliant prompts.
• Design reference architectures and SDKs for Voice AI, Agent Assist, QA & Monitoring, and Conversational Analytics; drive adoption via docs and enablement.
• Build fine‑tuning pipelines (data curation, SFT, preference/reward optimization, safety tuning) and automated eval gates prior to promotion.
• Define eval suites (faithfulness, answer relevance, context recall, ASR WER, latency budgets) and instrument tracing/attribution/redaction across the retrieval/generation chain.
• Partner with Data/Platform for governed deployment: role‑based access, audit trails, change capture, freshness SLAs, and model/asset lifecycle management.
• Lead vendor benchmarking and make build/buy/insource recommendations aligned to unit economics, reliability, and IP strategy.
• Mentor engineers/data scientists; review designs, prompts, datasets, and PRs; host tech talks and share reusable components across teams.

Benefits

• Health and Welfare Benefits: Medical (including prescription coverage), Dental, Vision, Health Savings Account, Health Care and Dependent Care Flexible Spending Accounts, Group Accident, Group Critical Illness, Life Insurance, AD&D, Group Legal, Identify Theft Protection, Wellbeing Program and Work/Life Resources (including Employee Assistance Program)
• Leave Benefits: Paid Holidays, Annual Paid Time Off (includes state/local paid leave where required), Short-Term Disability, Long-Term Disability, Other Leaves (e.g., Bereavement, FMLA, ADA, Jury Duty, Military Leave, and Parental and Adoption Leave)
• Retirement Benefits: Savings Plan with annual nonelective company contribution.
