Job Description

Key Responsibilities

  • Design,
    develop, and maintain prompt frameworks, including system prompts,
    few-shot examples, role-based prompts, and reasoning workflows for
    production-grade LLM applications.
  • Build and
    manage automated evaluation frameworks to measure model performance,
    accuracy, latency, and regression across releases.
  • Conduct
    structured A/B testing across prompt variations, model versions, and
    configuration settings to optimize task-specific outcomes.
  • Convert
    product requirements and edge-case scenarios into effective prompt
    instructions, personas, constraints, and guardrails.
  • Partner
    with ML engineers and product teams to determine when prompt engineering
    is sufficient versus when fine-tuning, RAG, or other AI architectures are
    required.
  • Create and
    maintain a centralized prompt repository with version control, documentation,
    and performance benchmarks for organizational reuse.
  • Lead
    red-teaming and adversarial testing exercises to identify jailbreak risks,
    hallucinations, and model vulnerabilities.
  • Define
    evaluation criteria, annotation guidelines, and quality standards to
    ensure consistency, safety, and reliability of AI-generated outputs.
  • Mentor
    engineers and stakeholders on prompt engineering best practices,
    evaluation methodologies, and the capabilities and limitations of modern
    LLMs.
  • Present
    prompt strategies, benchmark results, and trade-off analyses to product,
    engineering, and leadership teams.
  • Apply
    advanced prompting techniques, including chain-of-thought, zero-shot,
    few-shot, and role-based prompting.
  • Drive
    prompt testing, evaluation, benchmarking, and continuous optimization
    efforts.
  • Improve AI
    response quality through systematic assessment, tuning, and refinement.
  • Manage
    context handling and prompt orchestration for complex AI workflows.

Technical Skills

  • Strong
    programming and scripting skills in one or more modern programming
    languages
    (C#, Python, Javascript).
  • Experience
    building automation, evaluation pipelines, APIs, or AI-powered
    applications using enterprise-grade development practices.
  • Hands-on
    experience with LLM platforms, prompt engineering, model evaluation, and
    AI application development.
  • Familiarity
    with prompt orchestration frameworks, vector databases, RAG architectures,
    and AI agent workflows.
  • Understanding
    of data analysis, experimentation, benchmarking, and performance
    optimization.
  • Experience
    with version control systems, CI/CD pipelines, and cloud platforms.
  • Strong
    knowledge of REST APIs, JSON, and system integration patterns.
  • Ability to
    collaborate effectively with software engineers, data scientists, and
    product teams to deliver production-ready AI solutions.

Experience Requirements

  • 4-7 years
    of combined experience in NLP, AI/ML products, software development,
    technical writing, or related fields.
  • At least 2
    years of direct, hands-on prompt engineering experience with production
    LLM applications.
  • Proven
    track record of owning and managing prompt systems end-to-end, from design
    and implementation through monitoring and optimization in production.
