Senior Software Engineer, AI Infrastructure - Developer Tooling

About the Team

We're building the AI-powered backbone of our developer tools. You'll work on three core systems: a retrieval infrastructure powering our AI products, a coding agent that assists users in writing code, and the evaluation frameworks that measure their effectiveness.

Responsibilities

Retrieval Systems (RAG Infrastructure) - Design and scale retrieval pipelines including vector search, BM25, and hybrid retrieval strategies - Build and optimize embedding pipelines, chunking strategies, and re-ranking systems - Develop query understanding and rewriting components to improve retrieval relevance - Manage vector database infrastructure at production scale

Coding Agent Development

• Build agent architectures that support multi-step code generation, refactoring, debugging, and diagnostics
• Implement tool-use patterns (function calling, code execution sandboxing, file system interaction)
• Develop context management strategies for long-form code understanding

Evaluation & Benchmarking

• Design and maintain evaluation frameworks for retrieval quality and agent task completion
• Build custom benchmark suites for real-world coding task assessment
• Create reproducible testing infrastructure with automated regression detection
