Senior Backend Engineer (Python/FastAPI) – AI Evaluation (US-based)

What You'll Do6

• Curate code examples and write solutions in Python and JavaScript (React, Node.js), with additional work in C/C++, Java, Rust, and Go.
• Review AI-generated code across backend and frontend, correcting errors and improving efficiency, scalability, and reliability.
• Team with cross-functional groups to improve AI coding solutions against industry performance benchmarks.
• Build agents that verify code quality and spot error patterns in full-stack applications.
• Form hypotheses about steps in the software engineering cycle (prototyping, architecture design, API design, production implementation, launch, experiments, monitoring, maintenance) and assess model capabilities on them.
• Design automated verification mechanisms for software engineering tasks.

Requirements6

• 3+ years of software engineering experience.
• Strong expertise building full-stack applications with Python and JavaScript (React, Node.js).
• Experience deploying scalable, production-grade software with modern languages and tools.
• Deep understanding of software architecture, design, development, debugging, and code quality/review assessment.
• Excellent oral and written communication skills for clear, structured evaluation rationales.
• Must be based in the United States.

Preferred Qualifications2

• Experience at frontier AI companies such as OpenAI, NVIDIA, Databricks, Palantir, or Snowflake.
• Graduation from top computer science programs like Stanford, MIT, Carnegie Mellon, UC Berkeley, or Georgia Tech.

Who Should Apply

Candidates with 3+ years of full-stack engineering experience in Python and JavaScript, who have worked on production systems and can evaluate code quality, will thrive here. The role suits engineers from frontier AI labs or top CS programs who want to shape how LLMs learn to code.
