  • Apply secure SDLC and privacy‑by‑design practices (threat modeling, least privilege)
  • Collaborate with product, UX and domain experts to deliver customer‑focused solutions with measurable outcomes
  • Apply current LLM patterns (e.g., RAG, retrieval, routing, tool-use, evaluation) to deliver measurable customer value—faster, more reliable AI systems; reduced time-to-decision; improved trust/safety metrics; and lower cost per query
  • Lead by example through high-quality, maintainable code

Requirements

  • 5+ years of professional software engineering experience

  • Proven track record of secure, reliable and scalable cloud-native systems
  • Experience with AI solutions at scale, using advanced integration patterns (e.g., RAG, Agents) and frameworks such as LangChain
  • Experience with vector databases (e.g., Qdrant, FAISS, Chroma)
  • Strong problem-solving, ownership and cross-functional communication skills

Nice to have

  • Experience with experiments, A/B tests and model iteration based on user feedback
  • Understanding of retrieval systems (keyword search, vector search, embeddings) and ranking algorithms
  • Familiarity with emerging AI protocols (e.g., MCP, A2A, ACP)
  • Experience with cloud AI platforms (Azure OpenAI, Amazon Bedrock, GCP Vertex AI) or on-premise solutions (e.g., vLLM)
  • Experience with enterprise AI platforms (AWS AgentCore, Databricks AgentBricks, Google Agents Space, Azure AI Foundry)
