Job Description

Experience

  • Total IT 15 + Years
  • 4 7 years of software engineering with at least 2 years focused on LLM application development in production not research, not demos, not internal tools with 10 users
  • Has shipped an LLM-powered feature or product to production where real users depend on the accuracy and the engineer owns the quality metrics
  • Has owned an AI safety or guardrails implementation for a customer-facing product not just added an off-the-shelf filter; designed and tested the safety layer
  • Has built RAG evaluation pipelines and used them to make go/no-go release decisions accuracy gating is part of the workflow.
  • Has profiled and optimized a multi-step LLM call chain for latency

LLM Application Development

  • Multi-step LLM chain orchestration LangChain, LlamaIndex, or custom orchestration Expert Must have
  • Multi-turn conversation design context window management, conversation summarization, session memory Advanced Must-have
  • Streaming LLM response handling token-by-token streaming, partial response rendering Advanced Must-have
  • Model selection and benchmarking matching model size to task; balancing latency, cost, and accuracy Advanced Must-have

RAG Pipeline Design & Quality

  • RAG pipeline design chunking strategy, embedding model selection, retrieval configuration Expert Must-have
  • Vector similarity search tuning index parameters, similarity thresholds, retrieval depth Advanced Must-have
  • Reranking cross-encoder rerankers, relevance scoring Advanced Must-have
  • RAG evaluation frameworks RAGAS, TruLens, or equivalent; automated eval pipelines Advanced Must-have
  • Hybrid search combining dense vector retrieval with BM25 or keyword search Proficient Nice to have

AI Safety & Guardrails

  • Prompt injection detection and mitigation Advanced Must-have
  • Jailbreak testing and red-teaming LLM systems Advanced Must-have
  • Content safety classifier integration Advanced Must-have
  • Hallucination detection and mitigation strategies Advanced Must-have
  • Topical control enforcing scope boundaries on LLM responses Advanced Must-have

Evaluation & Production Quality

  • Automated evaluation pipeline design test set curation, metric selection, regression detection Advanced Must-have
  • A/B evaluation methodology for prompt and model changes Proficient Must-have
  • Latency profiling for LLM call chains identifying bottlenecks across multi-step pipelines Proficient Must-have
  • Feedback loop design user signal collection, signal-to-retrieval-weight integration Proficient Must-have
  • Production model monitoring accuracy drift detection, quality degradation alerting Proficient Must-have

Development

  • Python ML/AI application development, async programming Expert Must-have
  • API design for AI services streaming endpoints, error handling, timeout management Advanced Must-have
  • Embedding model operations model selection, batch embedding, index updates Advanced Must-have

Nice to Have

  • Adaptive learning systems or personalization engine experience
  • Knowledge graph integration with RAG
  • Multi-agent orchestration patterns
  • ServiceNow API integration
