AI Engineer ||

Role Summary The AI Engineer is responsible for designing and delivering AI-powered solutions that improve engineering productivity and business workflows. This role requires a strong foundation in AI/ML concepts, with hands-on expertise in LLM systems, data preparation, and context design (including chunking) to build scalable, high-quality AI solutions.

Design Data, Context & Chunking Strategies (Critical)

Structure and prepare data for LLM consumption, including effective chunking and context window optimization Design retrieval strategies that improve relevance, accuracy, and response quality Balance context size, latency, and cost while maintaining solution effectiveness

Apply Strong AI/ML Foundations

Understand and reason about model behavior, evaluation, bias, and limitations Tune and adapt prompts, context, and workflows instead of relying on model retraining Ensure responsible and effective use of AI through sound engineering practices

Drive Engineering Productivity with AI

Hands-on experience with:

Prompt engineering and LLM orchestration frameworks Context design, chunking strategies, and retrieval techniques Working with structured and unstructured data for AI use cases

Solid software engineering and system design experience Ability to build end-to-end AI solutions (data → context → LLM → application) Pragmatic mindset focused on quality, usability, and business impact
