Senior Software Code Reviewer

About Vetto

Vetto is a tech company focused on building and scaling high-quality datasets for artificial intelligence systems. We work at the intersection of human expertise and AI, ensuring that models are trained on technically accurate, well-defined, and realistic data.

Our projects support the training and evaluation of Large Language Models (LLMs), where technical rigor and correctness are non-negotiable.

About the Project

This project focuses on the technical review and validation of coding tasks used to train AI models. Coding challenges are generated automatically by AI, and your role is to evaluate quality of the challenge.

The core questions you will be answering on every task:

Are the requirements well defined?

Are the associated tests correctly validating the requirements?

Tests are treated as the mechanism of truth in this context. Mistakes here propagate at scale into AI systems — error criticality is high.

Languages

Tasks in this project involve code written across multiple languages. You will be expected to review and evaluate tasks in any of the following:

Python

JavaScript / TypeScript

Go

Rust

Java

Responsibilities

Evaluate whether the coding task itself is clearly and correctly defined

Validate whether tests accurately reflect whether the problem has been solved

Determine whether a solution that passes the tests genuinely solves the underlying problem

Apply strict technical criteria and quality standards consistently across tasks

Required Profile

This role is designed for mid/senior-level software engineers with real professional experience.

Technical requirements

Proven professional experience in software development (production environments)

Experience reviewing and evaluating code written by other engineers

Solid understanding of automated testing — how tests validate (or fail to validate) behavior

Experience contributing to or working with open source projects

High attention to detail and strong technical judgment

Comfortable working fully in English (reading and writing)

Nice to have

Experience with test-driven development (TDD) or test design

Familiarity with large or complex codebases
