  • Investigate production issues using logs, metrics, distributed tracing, and monitoring dashboards.
  • Write and maintain regression tests using Jest, Supertest, or PyTest, including tests for non-deterministic LLM behavior.
  • Use agentic coding tools in daily development work and verify AI-generated output when needed.
  • Work with observability and evaluation tools for LLM systems, including prompt/trace platforms and eval frameworks.
  • Collaborate in Agile workflows using Jira and Confluence and communicate root causes and fixes to stakeholders.
  • Own issues from triage through production verification and post-mortem analysis.

  • Experience with Redis, S3/MinIO, Docker/Kubernetes, and the AWS ecosystem.
  • Familiarity with LLM observability and evaluation tools such as Langfuse or similar platforms.
  • Strong analytical skills, a product-driven mindset, and the ability to architect fault-tolerant, maintainable systems.
