- Build and improve shared systems such as:
- Tool abstractions
- Retrieval pipelines / RAG systems
- Conversation persistence
- Evaluation frameworks
- Permissioning and observability
- Collaborate closely with Product, Design, and Engineering leadership to define technical direction and product strategy
- Make thoughtful engineering tradeoffs balancing latency, reliability, scalability, and cost efficiency
- Improve AI system quality through experimentation, evaluation frameworks, and continuous iteration
- Lead or contribute to large-scale technical initiatives across multiple teams
- Mentor engineers and promote engineering best practices across the organization
Required Qualifications
- 5+ years of professional software engineering experience
