Job Description

Job Title: Senior Software Engineer

Job Type: Contractor

Location: Remote

Job Summary: In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.

Key Responsibilities:

Contribute expert-level knowledge to bug fixing, feature implementation, codebase refactoring, and performance optimization across a range of programming languages.

Analyze and enhance software codebases to ensure clarity, maintainability, and efficiency.

Collaborate with multidisciplinary teams to provide feedback and insights for AI model improvement.

Develop robust solutions and document best practices to support scalable AI training workflows.

Evaluate existing system architecture and recommend technical strategies for optimal results.

Deliver clear, concise written and verbal communication regarding technical findings and project progress.

Support the continuous improvement of AI systems by providing real-world coding expertise in challenging scenarios.

Required Skills and Qualifications:

Proficiency in Python3, Java, Rust, or TypeScript, with additional experience in C++ or Go considered a strong asset.

Deep understanding of algorithms, data structures, and performance tuning.

Demonstrated experience in debugging complex software issues and delivering maintainable solutions.

Strong background in feature development and codebase refactoring.

Proven ability to optimize software for performance and scalability.

Exceptional written and verbal communication skills, with a keen attention to detail.

Track record of success in collaborative, cross-functional teams, ideally in remote settings.

Preferred Qualifications:

Previous experience working on large-scale, distributed codebases.

Familiarity with modern AI or machine learning systems is a plus, though not required.

Background in participating in rigorous code reviews and contributing to the development of software best practices.

We are seeking strong Software Engineers to join our customer's team with expertise in Python3, Java, Rust, Go, C++, or TypeScript. This is a unique opportunity to directly impact the next generation of AI by leveraging your advanced engineering skills in a dynamic, remote setting.
