Node.js Software Engineer - Remote

We are looking for experienced software engineers to help train and evaluate next-generation AI systems through real-world software engineering tasks. This role is best suited for developers who can reason through unfamiliar codebases, explain engineering decisions clearly, and solve practical backend, full-stack, systems, or infrastructure-related problems.

• Work on challenging software engineering tasks across backend, full-stack, infrastructure, and systems-related projects.
• Review, debug, improve, and explain code across different technical environments.
• Design or evaluate practical solutions involving APIs, databases, services, integrations, testing, and deployment workflows.
• Identify tradeoffs around scalability, maintainability, performance, reliability, security, and developer experience.
• Communicate technical reasoning clearly in writing, including why a solution works and what alternatives were considered.
• Collaborate with the customer’s team on technical reviews, implementation decisions, and problem-solving exercises.
• Adapt quickly to new codebases, frameworks, and technical requirements.

• 5+ years of hands-on software engineering experience.
• Strong experience in at least one backend or full-stack engineering environment, such as Python, JavaScript/TypeScript, Node.js, Java, C#, .NET, C++, Go, Ruby, PHP, or similar.
• Experience building, maintaining, or reviewing production-level applications, APIs, services, databases, or integrations.
• Strong understanding of software engineering fundamentals, including debugging, testing, code quality, architecture, and technical tradeoffs.
• Ability to explain complex engineering decisions clearly and objectively.
• Comfortable reading and reasoning through unfamiliar code or technical requirements.
