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

What You'll Do7

• Curate code examples and build solutions to train and benchmark large language models.
• Evaluate and refine AI-generated code with a focus on systems-level correctness, performance, and reliability.
• Collaborate with cross-functional teams to improve AI-driven coding solutions against industry benchmarks.
• Build agents that verify the quality of systems-level and infrastructure code and identify error patterns.
• Hypothesize on steps in the software engineering cycle (prototyping, architecture design, API design, production implementation, launch, experiments, monitoring, operational maintenance) and assess model capabilities.
• Design verification mechanisms that automatically validate solutions to software engineering tasks.
• Provide precise corrections and structured evaluation rationales for code in Python, C/C++, Rust, Go, Java, and JavaScript (including ReactJS).

Requirements5

• 3+ years of software engineering experience.
• Strong expertise in systems programming, infrastructure, or backend development using languages like Python, C/C++, Rust, and Go.
• Experience building and 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.

Who Should Apply

Candidates with at least 3 years of software engineering experience, particularly those who have built production systems at high-scale companies or hold strong CS degrees, should apply. The role suits engineers proficient in Python, C/C++, Rust, Go, Java, or JavaScript, with a deep understanding of systems-level code quality and a knack for structured evaluation.
