Cyble is a cyber intelligence company that empowers organizations with darkweb & cybercrime monitoring and mitigation services.

We are a fast-growing technology company leveraging large language models and AI to power next-generation applications. Our teams deliver high-impact solutions across diverse domains while maintaining a culture of curiosity, collaboration, and continuous learning.

We’re seeking a skilled Prompt / AI Engineer to design, implement, and optimize natural-language prompts, chains, and retrieval-augmented workflows. You’ll partner with engineering, product, and data science teams to ensure seamless integration of LLM capabilities into our services.

What You'll Do At CYBLE:

• Prompt Design & Optimization

1. Craft and iterate prompt templates for a variety of use cases (summarization, classification, Q&A)
2. Implement few-shot examples, chain-of-thought techniques, and dynamic parameterization
3. Benchmark, profile, and refine prompts to balance accuracy, latency, and cost

• Workflow & Chain Development

1. Build multi-step LLM pipelines using frameworks like LangChain, LlamaIndex, or equivalent
2. Integrate retrieval-augmented generation (RAG) with vector stores and document loaders
3. Develop agentic workflows that orchestrate API calls, data enrichment, and user interactions

• Model Integration & Testing

1. Integrate with public and private LLM services (e.g., OpenAI, Anthropic, self-hosted models)
2. Automate performance tests, error-handling routines, and hallucination checks
3. Monitor usage metrics, implement rate-limits, and optimize token budgets

• Collaboration & Documentation

1. Work closely with backend/frontend engineers to expose LLM endpoints
2. Create and maintain a prompt library, testing suite, and best-practice guidelines
3. Conduct reviews, knowledge transfers, and training sessions on prompt engineering

What You’ll Need:

• 3+ years of experience in AI/ML, NLP, or software engineering with a focus on prompt or LLM integration

• Strong proficiency in Python and familiarity with LLM client libraries

• Hands-on with at least one orchestration framework (LangChain, LlamaIndex, Dify, etc.)

• Experience working with vector databases (Pinecone, Weaviate, Qdrant) or embedding services

• Solid understanding of prompt-engineering techniques, chain-of-thought, and RAG concepts

• Ability to benchmark, profile, and optimize model calls for performance and cost

• Excellent written communication for clear documentation and prompt examples

Preferred (Nice-to-Have)

• Experience fine-tuning or prompt-tuning domain-specific models

• Familiarity with self-hosted LLM deployments (Hugging Face, OpenAI local runtimes)

• Background in automated evaluation metrics (ROUGE, BLEU, custom tests)

• Contributions to open-source prompt libraries or agent frameworks

• Exposure to CI/CD for AI services and observability tools

What We Offer

• Impactful Projects: Shape core LLM-driven capabilities across diverse applications

• Innovative Environment: Work with cutting-edge models, RAG pipelines, and agent frameworks

• Growth & Learning: Access to mentorship, training budgets, and conference support
