Senior AI/ML Engineer (GenAI & LLM Systems)

About the Role

TEKHQS is seeking a Senior AI/ML Engineer to design, fine-tune, and deploy production-grade Generative AI and LLM-powered systems. This role is ideal for engineers who have shipped real-world ML systems, understand modern transformer architectures, and can operate across the full ML lifecycle—from data and training to inference and optimization.

You will work on scalable AI platforms, enterprise-grade GenAI solutions, and intelligent systems integrated into Web, ERP, and enterprise workflows. This is a hands-on role with strong ownership and architectural influence.

Key Responsibilities

• Design, fine-tune, and optimize transformer-based models (GPT, LLaMA, Mistral, T5) for production use cases.
• Build and maintain end-to-end GenAI pipelines: data processing, training, evaluation, deployment, and monitoring.
• Implement Retrieval-Augmented Generation (RAG) systems using vector databases and hybrid search.
• Optimize inference for latency, throughput, and cost efficiency.
• Work with multi-modal AI (text, embeddings, images, audio where applicable).
• Integrate AI services into enterprise applications, ERP systems, and SaaS platforms.
• Collaborate with product, backend, and cloud teams to deliver scalable AI solutions.
• Apply best practices in ML governance, security, and responsible AI.

Required Skills & Experience

Core AI / ML

• Strong experience with PyTorch and transformer architectures.
• Hands-on experience with LLMs, embeddings, fine-tuning (LoRA/QLoRA), and prompt engineering.
• Solid understanding of training vs inference tradeoffs, evaluation metrics, and model behavior.

GenAI & Systems

• Experience with RAG pipelines, vector databases (Pinecone, Weaviate, FAISS, Chroma).
• Familiarity with RLHF concepts (DPO, PPO, reward modeling) is a plus.
• Tokenization concepts (BPE, SentencePiece, Tiktoken).

Model Optimization & Deployment

• Quantization and optimization techniques (GPTQ, AWQ, int8, fp16).
• Model serving using vLLM, Triton, HuggingFace TGI, or similar.
• Experience deploying models on AWS, Azure, or GCP.

Data & Infrastructure

• Distributed training or inference using DeepSpeed, FSDP, Accelerate.
• Data pipelines using Parquet, WebDataset, or cloud storage.
• CI/CD for ML workflows.

Software Engineering

• Strong Python engineering practices.
• Docker and Kubernetes for ML workloads.
• Experience with monitoring, logging, and profiling ML systems.

Nice to Have

• Experience with ERP-integrated AI solutions (NetSuite, SAP, Dynamics).
• Exposure to multi-agent systems, orchestration frameworks, or AutoGen/LangGraph.
• Open-source contributions or published technical work.

Qualifications

• Bachelors or Masters degree in Computer Science, AI, Data Science, or related field.
• 4+ years of professional ML experience, with 3+ years in GenAI/LLMs.
• Proven experience deploying AI systems to production.
