Job Summary Unico Connect is seeking a Senior AI Engineer to architect and deliver production AI systems for enterprise clients across the United States, European Union, and Asia-Pacific markets. This role leads multi-agent orchestration, large-scale Retrieval-Augmented Generation (RAG), evaluation infrastructure, and the engineering practices that take artificial intelligence from proof of concept to compliance-ready production. The position suits engineers with a demonstrated track record of shipping production LLM systems and the technical maturity to debug them when they fail.

Responsibilities

- Architect production AI systems including multi-agent orchestration, retrieval pipelines, evaluation infrastructure, and observability, with documented design rationale prior to implementation
- Lead RAG implementations at enterprise scale: chunking strategy, hybrid search, reranking, caching layers, and multi-tenant index architecture
- Design model-routing and tiering logic that balances cost, latency, and quality, including build-versus-buy decisions for self-hosted versus frontier model APIs
- Build evaluation harnesses combining golden test sets, LLM-as-judge pipelines, behavioural metrics, and regression detection that gate production deployments




- Mentor 2-3 AI Engineers; conduct AI-specific code reviews where evaluation scores, not unit test pass rates, define the quality bar
- Drive infrastructure decisions across Google Cloud Vertex AI, AWS Bedrock, Modal, and self-hosted serving platforms based on workload, compliance, and cost constraints
- Partner with the Tech Lead, Product Managers, and Senior Backend Engineers on the AI roadmap; negotiate scope when engineering reality requires it
- Deliver voice AI, computer vision, and multimodal features as project requirements demand; the role is not limited to text-based LLMs
- Lead production incident response when agents misroute tool calls or retrieval pipelines surface poisoned context
- Drive AI engineering standards across the firm: prompt versioning, evaluation coverage thresholds, observability baselines, incident post-mortems
- Contribute 1 open-source patch, technical write-up, or internal evaluation framework improvement each quarter
- Represent Unico Connects AI engineering capabilities in technical conversations with clients, prospects, and architecture review sessions

Qualifications

- 5+ years of professional software engineering experience, with at least 2 years dedicated to production AI / ML systems




- Multiple production LLM products shipped with measurable business outcomes; able to articulate the metrics moved and architecture trade-offs accepted
- Deep proficiency in Python including FastAPI, async patterns, streaming responses, and typed code with Pydantic at production scale
- Strong fundamentals in vector retrieval, embedding models, hybrid search architectures, and reranking strategies
- Hands-on experience with at least 2 of LangChain, LangGraph, LlamaIndex, Haystack, or comparable custom orchestration frameworks
- Demonstrated track record with evaluation tooling such as LangSmith, Ragas, or Phoenix, with the discipline to catch regressions before users report them
- Practical experience with fine-tuning techniques (LoRA, QLoRA, DPO) and self-hosted model deployment using vLLM, TGI, or comparable serving platforms
- Strong fundamentals in distributed systems and asynchronous backend design
- Excellent written communication; architecture decision records, design documents, and incident post-mortems as a default working medium
- Comfort delivering under regulated industry constraints such as SOC 2, HIPAA, GDPR, and FERPA when project scopes require it
- Bachelors degree in Computer Science, Artificial Intelligence, or a related engineering field, or equivalent demonstrated experience
