• Develop AI-powered pipelines for code quality checks, ticket auto-classification, documentation updates, release notes, and meeting summaries.

• Work on prompt engineering, model selection and routing (Haiku / Sonnet / Opus), and workflow optimization.

• Build evaluation and regression frameworks for AI workflows to prevent model-upgrade regressions.

• Create lightweight dashboards for engineering leads to surface delivery patterns and bottlenecks.

• Own initiatives end-to-end: scope → design → ship → measure → iterate.

• Strong understanding of RAG systems: chunking, embeddings, hybrid search, re-ranking, grounding/citations.

• Prompt engineering + structured outputs + tool/function calling.

• Experience with eval/regression frameworks: Promptfoo, Ragas, LangSmith, or custom evaluation harnesses.

• Agentic patterns: ReAct, function-calling loops, fallbacks.

• Vector databases: pgvector, Pinecone.

• Workflow orchestration: n8n, Airflow, or custom orchestration systems.

• Observability: token-spend tracing, latency monitoring, model routing.

• Solid AWS fundamentals: IAM, Lambda, S3, CloudTrail — comfortable deploying inside VPC environments independently.

• CI/CD + pipeline hooks (GitLab/GitHub), webhooks, event-driven architectures.

• Basic SQL skills for analytical queries and metrics dashboards.

• Driver mindset: proactively identifies the highest-leverage opportunity and drives it to production

• B2 English level

 


Would be a plus

• Real REST integrations with 2–3+ APIs

• Experience with workflow orchestration tools.

• Prompt evaluation tooling such as LangSmith is nice to have

• Experience with Docker

• RAG experience: embeddings and vector stores (pgvector, Pinecone, or similar) for knowledge base use cases
