• Experience designing observability, monitoring, logging, and alerting solutions for distributed systems.
• Strong software engineering ability beyond basic scripting.
• Ideally someone who has contributed to larger software projects or built maintainable platform/backend tooling in a language such as Python, Go, Java, TypeScript, or similar.
• Comfortable using modern AI-assisted engineering workflows, including agentic coding tools and LLM-based automation.
• Familiarity with concepts such as MCP servers, tool-calling, RAG/vector search, embeddings, and AI-assisted platform operations.
• Working knowledge of databases and data platforms, including SQL databases such as PostgreSQL/MySQL and exposure to NoSQL or distributed data stores.
• Track record of independently scoping and delivering complex infrastructure projects end-to-end.
• Experience mentoring engineers and sharing technical expertise across a team.
• Excellent communication and stakeholder management skills.
