AI Prompt Engineer / Applied AI Specialist

We are looking for an Applied AI Specialist with strong expertise in Prompt Engineering to join a leading defense organization in Tel Aviv.

This is a highly hands-on role focused on designing, building, testing, and improving interactions between users, software systems, and advanced language models.
The role can suit professionals coming from software engineering, AI Product, or Computational Linguistics, provided they have a strong understanding of how natural language translates into accurate, consistent, and reliable AI behavior.

Responsibilities
Design, write, test, and optimize prompts for LLM-based systems
Build complex prompt flows and interaction logic with language models
Improve response quality, consistency, and accuracy through experimentation, evaluation, and iterative prompt engineering
Work with structured outputs, tool/function calling, and agentic workflows
Adapt language, context, and instructions to different operational and professional use cases
Analyze model failures, identify recurring patterns, and develop improvement mechanisms
Collaborate closely with software engineers, product teams, data professionals, and domain experts
Evaluate and implement new Generative AI capabilities in existing and new systems
Develop software components and integrations when required as part of broader AI solutions
