Title and Summary

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.

What You Will Do

Lead AI-Driven Solution Development

Identify and drive high-impact AI use cases across engineering and business workflows

Design end-to-end AI solutions leveraging LLMs, orchestration, and automation

Move rapidly from exploration to production-grade implementations

Build LLM Solutions & Intelligent Agents

Develop LLM-based applications including prompt frameworks, orchestration layers, and integrations

Create and evolve AI-powered agents (e.g., Copilot-based or similar) for workflow automation and decision support

Apply techniques such as retrieval-augmented approaches, context management, and prompt optimization

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

Apply AI tools (e.g., Copilot and similar) to improve developer velocity and quality

Build reusable patterns for AI-assisted coding, testing, and documentation

Measure and scale productivity impact across teams

Data & Application Engineering

Build data pipelines and integrations to support AI workflows

Develop APIs, services, and applications embedding AI capabilities

Ensure solutions are scalable, maintainable, and integrated into real workflows

What You Bring

Strong foundation in AI/ML concepts, especially LLMs and modern AI systems

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
