Full-Stack Software Engineer Location: Global, fully remote Job Type: Contractor (~15 hours per week) Schedule: Flexible—you choose the hours and days you work, including weekends if desired as long as there is activity. We are looking for highly skilled Full-Stack Software Engineers to contribute to an AI training project involving software development, technical problem-solving, debugging, system architecture, and code evaluation. The work involves creating, solving, reviewing, and validating challenging software-engineering tasks across front-end and back-end systems and helping with translating full coding builds from one particular language into another. This role requires meaningful hands-on experience across both front-end and back-end engineering. Candidates should be comfortable working throughout the application stack rather than specializing exclusively in one layer. What You’ll Work On - Develop, modify, and debug front-end and back-end application components. - Implement user-facing features and the services, APIs, and data models that support them. - Trace requests and data across browsers, front-end applications, APIs, services, databases, and external integrations. - Work inside unfamiliar repositories and understand existing application architecture. - Diagnose failures involving application state, API contracts, authentication, persistence, networking, and deployment. - Evaluate and improve code written in multiple programming languages. - Review AI-generated solutions for correctness, completeness, performance, security, and maintainability. Required Qualifications - Strong professional experience developing production full-stack applications. - Meaningful hands-on experience with both front-end and back-end engineering. - Production experience with multiple programming languages. - Strong knowledge of browser applications, APIs, application state, databases, and service integration. - Experience understanding and contributing to the architecture of complete software systems. - Ability to work effectively in unfamiliar codebases. - Strong debugging and technical problem-solving skills. Process - Apply to the role and complete the screening questions. - Complete an AI interview of approximately 30 minutes. - Complete a technical assessment, if required. - Complete the hiring manager review. Compensation Structure Compensation is output-based. Experts are paid per task that meets the project specifications.
