• Collaborate with engineering business teams to identify and deliver high-value AI use cases.
• Evaluate and integrate commercial, open-weight, and proprietary AI models based on business and technical requirements.
• Build and maintain AI workflows involving embeddings, retrieval, model orchestration, tool calling, and structured outputs where appropriate.
• Deploy and operate AI solutions using DevOps and MLOps practices, including CI/CD, versioning, monitoring, and rollback.
• Evaluate and monitor AI solutions for quality, reliability, performance, latency, cost, and business outcomes.

Essential Qualifications

• Bachelor's degree in Computer Science, Software Engineering, Data Science, Engineering, or a related discipline, or equivalent practical experience.
• 3-7 years of software engineering, machine learning engineering, or AI engineering experience, or a related role.
• Strong software engineering experience with proficiency in Python or an equivalent programming language and experience developing APIs or backend services.

• Strong troubleshooting and problem‑solving skills across application, infrastructure, AI model, and integration layers.

Preferred Qualifications

• Experience with AI‑assisted development or agentic coding tools in private or enterprise environments.
• Experience with large language models such as Llama, Mistral, Qwen, DeepSeek, or equivalent open‑weight models.
• Experience with model inference platforms such as vLLM, Ollama, llama.cpp, Hugging Face Transformers, or equivalent technologies.
• Experience with agent and workflow orchestration frameworks such as LangGraph, Semantic Kernel, AutoGen, or equivalent technologies.
• Experience with model evaluation, benchmarking, prompt evaluation, groundedness and response‑quality assessment, and regression testing for AI applications.
• Familiarity with model quantization and efficient inference techniques, such as GPTQ, AWQ, GGUF-based deployments, or similar approaches.
