Senior Al Engineer
cornerstone
Job Description
- Build and own backend features — design, implementation, testing, code review, and production monitoring.
- Work on our LLM integration layer: streaming AI responses, prompt engineering, structured output parsing, and response validation.
- Contribute to our RAG and semantic search architecture — hybrid vector search, caching strategies, and data ingestion pipelines.
- Build rich, interactive frontend experiences in React/TypeScript that render AI-generated content in real time.
- Improve our NL-to-SQL pipeline that translates natural-language questions into validated analytics queries.
- Participate in architecture discussions, technical design reviews, and cross-team collaborations.
You've got what it takes if you have...
- 3–5 years of experience building production backend services in any major language (Java, Python, Go, etc.).
- Working experience with TypeScript and React, or a strong willingness to work full-stack.
- Solid understanding of REST API design, distributed systems, and service-oriented architecture.
- Experience integrating LLMs into production systems — prompt design, streaming responses, or structured output handling.
- Experience with AWS services and containerized deployments (Docker, Kubernetes).
- Strong engineering fundamentals: you care about test coverage, code review quality, and observable, maintainable systems.
