An organization is seeking a software engineer to join a development group building AI-first applications. The role blends solid software engineering practice with hands-on experience creating systems that use large language models, retrieval-augmented generation, conversational assistants, and agent-driven workflows.

  • Establish safe, practical patterns for tooling, human approval gates, and controlled agent behavior; advise on model and framework choices with attention to accuracy, cost, latency, maintainability
  • Diagnose and resolve common AI system problems such as model hallucinations, poor retrieval relevance, excessive response times, ineffective cost profiles, and unstable outputs
  • Work closely with software engineers and product or business stakeholders to embed AI engineering best practices and help shape the technical roadmap

What they ask

  • Analytical decision-making for AI versus deterministic solutions
  • Cloud-native application development
  • AI application evaluation methods including test datasets, quality metrics, regression testing, and user feedback
