Job Summary
We are looking for a Prompt Engineer to design, test, and optimize prompts and workflows for large language models (LLMs). The role focuses on improving the accuracy, reliability, and usefulness of AI-generated outputs across business, technical, and customer-facing use cases. You will work closely with product, engineering, data, and business stakeholders to translate requirements into effective AI interactions.
Responsibilities and Duties
- Design, write, and iterate prompts for large language models to achieve consistent and high-quality outputs
- Develop prompt frameworks, templates, and reusable patterns for different use cases (classification, summarization, extraction, reasoning, generation)
- Test and evaluate model responses, identifying failure cases, bias, hallucinations, and performance gaps
- Optimize prompts using techniques such as few-shot learning, chain-of-thought, role prompting, and tool-based prompting
- Collaborate with software engineers to integrate prompts into applications, APIs, and workflows
- Work with product and business teams to understand requirements and translate them into AI behavior
- Document prompt strategies, best practices, and evaluation results
- Stay current with advancements in LLM capabilities, limitations, and prompt engineering techniques
- Support A/B testing and experimentation to continuously improve AI performance
Qualifications and Skills
- Strong written communication skills in English
- Experience working with large language models (e.g., GPT-style models, Claude, LLaMA, or similar)
- Understanding of natural language processing concepts and limitations of generative AI
- Ability to think analytically and systematically about language, instructions, and edge cases
- Experience testing and evaluating AI outputs against qualitative and quantitative criteria
Preferred qualifications
- Background in software engineering, data science, linguistics, cognitive science, or technical writing
- Experience with Python, JavaScript, or similar languages for prompt testing and automation
- Familiarity with AI evaluation methods, prompt versioning, and experimentation frameworks
- Experience working with APIs and AI platforms
- Knowledge of responsible AI practices, bias mitigation, and prompt safety
Nice to have
- Experience building internal AI tools or copilots
- Exposure to RAG (retrieval-augmented generation) or tool/function calling
- Experience supporting business domains such as customer support, recruiting, finance, or healthcare
