Job Overview

• We're looking for highly experienced Fullstack Engineers to work on frontier AI projects, especially around improving Large Language Models (LLMs) for software engineering tasks. You'll support the development of LLM training and evaluation datasets by assessing code generated by models, building agent-based tools, and analyzing complex real-world software.
• You’ll work with teams pushing the boundary of AI-assisted development to identify weaknesses in model behavior and provide detailed code assessments. The goal is to build smarter, more context-aware AI coding tools that function in realistic development environments.

Key Responsibilities

• Work across multiple LLM-related projects aimed at improving AI model performance on code.
• Lead end-to-end engineering efforts for agent use cases like home automation, coding copilots, and creative assistants.
• Review and rank model-generated code snippets using a structured evaluation system.
• Evaluate code diffs for correctness, style, maintainability, and performance.
• Build scalable fullstack applications to support dataset pipelines and tooling.
• Collaborate with researchers to uncover edge cases and complex code behaviors.
• Write clear, structured rationales to explain code assessment outcomes.

Must-Have Skills

• 10+ years of experience in software engineering with strong fullstack capabilities.
• At least 2–3 years as a full-time employee (not contractor) at a top-tier tech company (e.g., Google, Meta, Microsoft, Amazon, Stripe, etc.).
• Deep expertise in software architecture, debugging, and code review.
• Proven ability to assess large, realistic codebases and evaluate code quality.
• Strong written and oral communication for clear and logical evaluations.
• Hands-on experience with Git, code versioning, modern frameworks, and cloud platforms.
