Prompt Engineer

Siemens Healthineers

About Us

The Center for Competence (CoC) team on Generative AI within Siemens Healthineers Development center is responsible for providing productivity gains for the Product development lifecycle for the R&D organizations with a services, solutions and tool development to be used in the development of internal and external applications.

Job description:

The primary role is to harness the power of prompt-based AI models, such as GPT (Generative Pre-trained Transformer) models, to generate human-like text or responses to specific queries or tasks. These models have a wide range of applications, including natural language understanding, chatbots, content generation, and more. A Prompt Engineer is responsible for configuring and fine-tuning these models to produce desired outputs efficiently and effectively.

Roles and Responsibilities:

  • Model Configuration: Configure the AI model with appropriate prompts and parameters to achieve desired text generation outcomes. This involves understanding the specific use case and tailoring the model accordingly.
  • Fine-tuning: Fine-tune pre-trained models on specific datasets to adapt them to the intended task or domain. This process requires expertise in transfer learning and data preprocessing.
  • Prompt Engineering: Craft effective prompts that elicit the desired responses from the AI model. This may involve designing templates, specifying context, and optimizing prompt input.
  • Performance Optimization: Continuously optimize the model’s performance in terms of output quality, coherence, and relevance. Implement techniques like temperature scaling, top-k sampling, and nucleus sampling to control the output.
  • Data Management: Handle data related to prompts and model inputs effectively. Ensure data integrity, cleanliness, and appropriate encoding for input into the AI model.
  • Monitoring and Debugging: Monitor model behavior and performance, identify issues, and debug problems as they arise. This includes addressing issues related to biased or inappropriate outputs.
  • Scaling and Deployment: Deploy prompt-based AI models in production environments, ensuring they can handle a high volume of requests efficiently and reliably. Implement model versioning and monitoring.
  • Ethical Considerations: Be aware of ethical considerations, such as bias, fairness, and privacy, and take steps to mitigate potential issues in the generated text.
  • Documentation: Maintain documentation of prompt configurations, model versions, and best practices for prompt engineering. Share knowledge within the team.
  • Collaboration: Collaborate with cross-functional teams, including data scientists, machine learning engineers, and domain experts, to align the model’s behavior with project objectives.

Key Skills Required:

  • Natural Language Processing (NLP): Proficiency in NLP concepts and techniques, including tokenization, text generation, and language modeling.
  • Deep Learning: Understanding of deep learning fundamentals, especially transformer-based models like GPT.
  • Programming Languages: Strong programming skills, particularly in Python, for scripting and model implementation.
  • Model Fine-tuning: Experience with fine-tuning pre-trained language models and transfer learning techniques.
  • Prompt Design: Ability to design effective prompts that produce desired AI model responses.
  • Data Handling: Skills in data preprocessing, data management, and data encoding for AI model inputs.
  • Performance Optimization: Knowledge of techniques to optimize the quality and diversity of generated text.
  • Deployment: Experience in deploying AI models in production environments using cloud services or containerization.
  • Ethical AI: Awareness of ethical considerations in AI, especially in text generation, and strategies to address biases and fairness issues.
  • Collaboration and Communication: Strong teamwork and communication skills to work effectively with multidisciplinary teams and stakeholders.
  • Monitoring and Debugging: Proficiency in monitoring model behavior and debugging issues in real-time.
  • Documentation: Ability to maintain clear and organized documentation for prompt configurations and model performance.

A skilled Prompt Engineer plays a crucial role in harnessing the capabilities of prompt-based AI models to deliver contextually relevant and high-quality text generation solutions across various domains and applications.
