AI Engineer

Our client is looking for an AI Engineer who can move fluidly between research and production: someone who can prototype a new model or prompting approach quickly, then harden it into a reliable, observable, cost-efficient service that runs at scale. You'll work closely with product and full-stack engineering to turn ambiguous problems into shipped AI features.

Responsibilities:

• Design, build, and deploy machine learning and LLM-based systems, including retrieval-augmented generation (RAG) pipelines, fine-tuned models, and agentic workflows.
• Own the full lifecycle of AI features: data collection and evaluation, model/prompt selection, experimentation, deployment, and monitoring in production.
• Build and maintain data pipelines, embeddings stores, and vector databases that support search, retrieval, and personalization.
• Evaluate and integrate third-party model APIs (OpenAI, Anthropic, etc.) alongside open-source and self-hosted models, balancing quality, latency, and cost.
• Fine-tune, train, and deploy open-source models on our own infrastructure — including data prep, training/fine-tuning runs, quantization, and self-hosted inference serving at scale.
• Stay current with the fast-moving AI/ML landscape and bring back practical recommendations on tools, models, and techniques.

Qualifications and experience:

• 4+ years of experience building and shipping machine learning or AI-powered systems in production.
• Strong Python skills, with hands-on experience using frameworks such as PyTorch, TensorFlow, or similar.
• Practical experience with large language models — prompting, fine-tuning, RAG, or agent frameworks (e.g., LangChain, LlamaIndex, or custom implementations).
• Hands-on experience training and fine-tuning open-source models (e.g., Llama, Mistral, Qwen) — full fine-tuning or parameter-efficient methods (LoRA/QLoRA) — and deploying them on your own infrastructure rather than relying solely on hosted APIs.
• Experience with vector databases and embedding-based retrieval (e.g., Pinecone, Weaviate, pgvector, FAISS).
• Comfort working with cloud infrastructure (AWS, GCP, or Azure) and containerized deployments (Docker, Kubernetes), including GPU-backed compute.
• Proficiency working with AI coding assistants (e.g., Claude Code, GitHub Copilot, Cursor) to accelerate development, while critically reviewing and validating AI-generated code.
• Experience with AI coding assistants such as Cursor, Claude, or similar Experience with AI coding assistants such as Cursor, Claude, or similar
