Sr. Full-Stack Software Engineer
About The Position
Our client is seeking experienced Senior Full-Stack Software Engineers for a fully remote, global, project-based artificial intelligence training opportunity. Engineers will contribute software development, technical problem-solving, debugging, system architecture, and code evaluation to help improve advanced AI systems’ coding and problem-solving capabilities. Selected professionals will create, solve, review, and validate complex software engineering tasks across the full application stack. The work includes developing and evaluating production-quality front-end and back-end software, translating complete implementations between programming languages, reviewing AI-generated code, and providing clear technical feedback. The position requires meaningful production experience across both front-end and back-end systems and the ability to work independently to established quality standards. This is an independent contractor engagement with a flexible schedule and an approximate commitment of 15 hours per week. Compensation is advertised at USD $50–$100 per hour, with payment based on approved output that meets project specifications. Candidates may need to complete an approximately 30-minute AI-based interview and a technical assessment, and should be able to begin promptly after selection and onboarding.
Requirements
- Strong professional experience developing and maintaining production-level full-stack applications.
- Significant hands-on experience in both front-end and back-end software engineering.
- Production experience with multiple programming languages and technologies; examples include Python, React, JavaScript, Java, Node.js, Rust, Go (Golang), and TypeScript.
- Strong understanding of modern web application architecture, browser-based applications, APIs, and backend services.
- Experience designing, developing, and maintaining user-facing features and their supporting backend systems.
- Knowledge of application state management, databases, data persistence, and service integrations.
- Ability to navigate and contribute effectively to unfamiliar codebases and existing software architectures.
- Strong debugging and troubleshooting skills across the complete application stack.
- Experience diagnosing complex technical issues involving authentication, API contracts, networking, and deployment.
- Ability to evaluate implementations for correctness, completeness, performance, security, and maintainability.
- Strong analytical thinking, technical problem-solving, and software engineering judgment.
- Ability to work independently and deliver high-quality technical assignments in a remote environment.
- Availability to dedicate approximately 15 hours per week to project assignments.
- Willingness to complete an AI-based interview of approximately 30 minutes.
- Availability to complete a technical assessment if requested.
- Ability to begin assignments promptly following successful selection and onboarding.
