Senior AI Engineer

Sandgarden is a small, early-stage company where the distance between an idea and production is measured in days, not quarters. Our product is called Doc Holiday, an AI-native platform to keep organizations in sync as code ships, starting with release notes and documentation. We've raised $9M.

This is a software engineering role first. You'll design agent architectures, ship production systems, and iterate fast where your decisions shape the product. You won't be fine-tuning models or writing research papers.

Key Responsibilities:

• Design and ship AI agents that write and evaluate software documentation
• Own the full agent lifecycle from early prototype through production deployment
• Build agent primitives like agentic loops, retrieval and grounding strategies, multi-step orchestration, and memory
• Build RAG pipelines and evaluation frameworks to measure writing quality
• Establish best practices as products mature and shape the product roadmap

Required Skills:

• Hands-on LLM development experience (production or substantial projects)
• Ability to drive outcomes with incomplete direction
• Capacity to evaluate written output quality objectively

Tech areas: LLMs and agent architecture, RAG pipelines, multi-agent orchestration, evaluation frameworks, API and systems design.

Fully remote. We're a US-based company.
