Role Overview
We are seeking an AI Engineer to design and build intelligent agent systems based on cognitive architecture principles and neuro-symbolic reasoning. You will work on next-generation AI that combines LLMs, reasoning engines, memory systems, and planning modules — moving beyond pure deep learning toward explainable and controllable intelligence.


Key Responsibilities
Cognitive & Agent Architecture

• Design AI agent frameworks incorporating perception, memory, reasoning, planning, and action loops
• Implement structured memory (episodic, semantic, working memory) for long-running AI agents
• Build tool-using agents with multi-step decision making and task decomposition
• Develop evaluation frameworks for reasoning correctness and controllability

Neuro-Symbolic AI Development

• Combine neural models (LLMs/transformers) with symbolic reasoning (rules, graphs, constraints)
• Implement knowledge graphs, ontologies, and rule engines
• Build reasoning pipelines integrating logic solvers and neural inference
• Improve explainability, traceability, and reliability of AI outputs

LLM & ML Engineering

• Build retrieval-augmented systems (RAG), planning chains, and memory-aware prompting
• Implement fine-tuning, alignment, and evaluation workflows
• Optimize latency, cost, and reliability of inference pipelines
• Deploy AI services in scalable production environments

Platform & Collaboration

• Work closely with product and research teams to convert prototypes into production systems
• Participate in architecture reviews and experimentation cycles
• Write clean, testable, and well-documented code

Required Qualifications

• Strong programming skills in Python
• Experience building AI/ML or LLM-based applications in production
• Understanding of reason...
