Senior Python Engineer – LLM Evaluation (US-based)

What You'll Do6

• Curate code examples and build solutions in Python, C/C++, Rust, Go, Java, and JavaScript (including ReactJS) to support AI model training.
• Evaluate and refine AI-generated code for 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 detect 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 check solutions to software engineering tasks.

Requirements6

• 3+ years of software engineering experience.
• Strong expertise in systems programming, infrastructure, or backend development using languages such as 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 assessment.
• Excellent oral and written communication skills for clear, structured evaluation rationales.
• Must be based in the United States.

Preferred Qualifications2

• Experience at high-scale engineering organizations like Google, Microsoft, Apple, Amazon, or Meta.
• Graduation from programs with strong CS foundations such as University of Washington, University of Illinois Urbana-Champaign, UT Austin, University of Michigan, or Purdue.

Who Should Apply

Candidates with at least 3 years of software engineering experience, particularly in systems programming, infrastructure, or backend development using Python, C/C++, Rust, or Go, and who are based in the US. The role suits engineers who have built production systems at scale and can evaluate code quality with precision.
