Hybrid 3-5 years of professional experience
Short Description

We are seeking a highly skilled Prompt Engineer / System Engineer to join our multidisciplinary team working at the intersection of artificial intelligence, systems architecture, and infrastructure reliability. This role is ideal for someone with a deep understanding of large language models (LLMs), prompt design, and system engineering principles to help build, optimize, and maintain scalable, AI-driven solutions.

Description

Key Responsibilities: Prompt Engineering:

  •  Design, test, and refine prompts to optimize performance of large language models (e.g., GPT-4, Claude, LLaMA).
  • Develop prompt templates and reusable patterns for various use cases, including classification, summarization, generation, and dialogue.
  • Collaborate with product and data teams to understand use case requirements and translate them into effective prompt strategies.
  • Evaluate LLM responses and fine-tune prompts to reduce hallucinations, bias, or inappropriate content.
System Engineering:
  • Design and maintain scalable infrastructure for AI services, APIs, and model inference pipelines (on-prem or cloud).
  • Automate deployment and monitoring of AI components using CI/CD tools (e.g., Azure DevOps, GitHub Actions, Jenkins).
  • Implement robust logging, observability, and performance monitoring for AI applications.
  • Ensure system security, data privacy, and compliance with internal and external standards. 

Requirements

Required Qualifications: 

  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field. 
  • 3+ years of experience in system engineering, DevOps, or backend development. 
  • Experience with AI/LLM platforms like OpenAI, Anthropic, Cohere, or open-source models (e.g., Hugging Face). 
  • Strong skills in scripting and automation (e.g., Python, Bash). - Familiarity with containerization (Docker, Kubernetes) and cloud services (Azure, AWS, or GCP). 
  • Understanding of prompt engineering techniques, LLM limitations, and evaluation metrics. 
 Preferred Qualifications: 
  •  Experience fine-tuning or deploying custom LLMs. 
  • Knowledge of NLP concepts and transformer architectures. 
  • Familiarity with RAG (Retrieval-Augmented Generation), vector databases, and embeddings (e.g., FAISS, Qdrant, Pinecone). 
  • Experience with MLOps pipelines and model lifecycle management.
  • Security awareness in AI deployments (e.g., token protection, output filtering).
