AI Engineer (Python, GenAI/LLMs + ML Fundamentals)

Position Summary

We are hiring an AI Engineer for our Labs team a fast-moving group that prototypes emerging AI capabilities and takes the most promising ones to production at scale. You will operate at the intersection of research and engineering: turning new papers and ideas into working demos within days, then hardening them into reliable, production-grade systems. The ideal candidate stays on the frontier of AI, is hands-on with the full ML lifecycle, and thrives in ambiguity with a strong bias for action.

Job Specific Duties and Responsibilities

• End-to-end ML ownership: Drive the complete lifecycle data curation, model building, evaluation, deployment, monitoring, and retraining for both predictive and generative AI systems.
• Production-grade MLOps: Build scalable pipelines for training, CI/CD, model registry, A/B testing, drift detection, and automated retraining. Optimize inference for latency, throughput, and cost.
• LLMs and SLMs: Fine-tune and deploy open and closed models using techniques such as LoRA/QLoRA, PEFT, instruction tuning, and preference tuning (RLHF/DPO). Apply quantization and distillation where needed.
• Agentic systems: Design and productionize agentic frameworks RAG pipelines, tool/function calling, memory, planning loops, and multi-agent orchestration with appropriate guardrails and observability.
• Quality and trust: Build evaluation frameworks (offline + online, including LLM-as-judge and red-teaming). Diagnose and mitigate hallucinations, bias, and drift.
• Rapid innovation: Track SOTA research, prototype quickly, and showcase work through demos and tech talks to internal stakeholders and leadership.

REQUIRED QUALIFICATIONS

• 3+ years of hands-on experience as an AI/ML Engineer or Applied Scientist, with proven production deployments including at least one LLM-based or agentic system taken to production.
• Strong Python skills and solid software engineering fundamentals (version control, testing, design patterns, code reviews).
• Deep Learning & NLP: Strong grasp of transformer architectures, attention, tokenization, embeddings, and modern NLP techniques. Hands-on with PyTorch and the Hugging Face ecosystem (Transformers, PEFT, TRL, Accelerate).
• Agentic & RAG stack: Working knowledge of frameworks such as LangChain / LangGraph / LlamaIndex / CrewAI / AutoGen, plus vector stores (Pinecone, Weaviate, Qdrant, pgvector, or FAISS) and reranking strategies.
• Serving & optimization: Experience with inference servers such as vLLM, TGI, or Triton, and familiarity with quantization (GPTQ, AWQ, GGUF).
• MLOps & infra: Hands-on with tools like MLflow, Weights & Biases, Airflow, or Kubeflow; comfortable with Docker, Kubernetes, GPU workloads, and at least one major cloud (AWS / Azure / GCP).
• Soft skills: High bias for action, strong communication, ownership mindset, and intellectual curiosity.
• Nice to have: Open-source contributions, multimodal model experience, on-device SLM deployment, or familiarity with LLM security (OWASP LLM Top 10).

PREFERRED / NICE TO HAVE

• Agentic architectures (tool use, multi-step workflows, orchestration patterns).

• MLOps experience: model/version management, deployment automation, monitoring, drift/quality tracking, and rollback strategies.

• Experience with vector databases / search systems (semantic + keyword/hybrid retrieval).

• Cloud experience (AWS/GCP/Azure) and infrastructure fundamentals (IAM, secrets management, networking basics).

• Exposure to fine-tuning / adaptation techniques for smaller models where applicable.

SOFT SKILLS

• Strong problem-solving and ownership mindset; comfortable operating in ambiguity.

• Clear communication of technical tradeoffs and experiment results to stakeholders.

• Collaborative approach with engineering, product, and data teams.
