This contract role is for senior engineers who build the backend systems behind AI model development. The work covers high-performance pipelines, annotation tooling, and evaluation infrastructure that support model training and benchmarking. It is aimed at engineers with several years of production experience in Go, Rust, Python, or C++ who are fully remote and available 20 to 40 hours per week.
This contract role asks you to review code produced by AI models and to write backend solutions yourself, covering server-side logic and API design at several difficulty levels. It suits backend engineers who can judge code on correctness, efficiency and clarity and explain their reasoning in clear English. The work is fully remote and asynchronous, with a minimum of 15 hours per week.
This is a remote contract role building internal C tooling that supports data pipelines, annotation systems, and evaluation workflows for AI training. It is aimed at senior engineers with several years of production C experience who can also work across full-stack and interoperability tasks.
This contract role centers on building, reviewing, and improving production-grade Python code and data workflows that support AI development. It is aimed at senior engineers with at least four years of professional experience who can work independently, remotely, on task-based engineering problems.
This remote contract role asks Ruby engineers to review, evaluate and improve backend coding scenarios that are used to train AI systems. It suits experienced developers who can judge code quality, explain their reasoning clearly and work independently on task-based assignments.
This remote, task-based contract involves designing realistic engineering challenges that evaluate advanced AI agents on enterprise work such as diagnosing failing integrations, tracing bugs, and writing fixes. It is aimed at working software engineers who debug real systems, write infrastructure and configuration code, and can verify their fixes in live or simulated environments.
This is a remote hourly contract for a senior Rust engineer who will design and maintain high-performance data pipelines, annotation tooling, and evaluation systems used to train AI models. The work is production-focused, involves backend and tooling services, and suits engineers who can work independently with research and data teams.
This is a remote hourly contract for senior systems engineers who will build and tune the C++ infrastructure behind AI data pipelines, annotation tools and model evaluation. The work centers on performance, reliability and production fixes, carried out alongside research and engineering teams. It suits experienced C++ developers with a systems background who want to work on the infrastructure used to train and ship AI models.
This remote contract role asks senior TypeScript developers to review AI-generated code for type safety, scalability and modern practices. The work centers on writing structured feedback that helps AI models understand architectural choices and type logic. It is aimed at experienced developers who can work independently on flexible hourly commitments.
This contract role asks TypeScript developers to review and improve AI-generated code so it is type-safe, idiomatic, scalable and ready for production. It is aimed at senior developers with deep TypeScript knowledge who can clearly explain why a piece of code is well designed. No prior AI background is required.
Backend engineers will evaluate how AI models reason about system design, data modeling, and API contracts, identifying failures like race conditions and N+1 queries that only surface under real load. The role involves stress-testing model-generated backend code and writing correct solutions when models fall short, with explicit attention to scaling and consistency trade-offs.
A Full Stack Engineer working with frontier AI models to evaluate their ability to build complete applications across frontend, API, and database layers. You will trace features through the entire stack to identify where models fail, write corrected versions when needed, and provide detailed explanations that serve as training data for improving future model outputs.
You will evaluate AI-generated code by running models on real engineering tasks, analyzing their output against production standards, and stress-testing them to find failures. This role is ideal for experienced software engineers who want to contribute to AI model improvement through rigorous code review and red-teaming.
This contract role asks an experienced mobile engineer to design realistic coding challenges that test how well AI models handle mobile software problems such as bug fixing, feature building, refactoring and performance work. For each challenge the expert builds a reproducible environment, writes verifiers that accept varied correct solutions and reject shortcuts, and provides a reference solution. It suits developers with deep hands-on experience in React Native, Flutter, SwiftUI, UIKit, Jetpack Compose or Android Views.
