Sr. Full-Stack Software Engineer
Position: Sr. Full-Stack Software Engineer
Type: Contractor
Compensation: $50–$100/hour
Location: Remote — Global
About the Opportunity
micro1 is engaging highly skilled Full-Stack Software Engineers to contribute to an AI training project focused on software development, technical problem-solving, debugging, system architecture, and code evaluation.
The work involves creating, solving, reviewing, and validating challenging software-engineering tasks across both front-end and back-end systems. Experts may also work on translating complete software builds from one programming language into another while maintaining functionality, correctness, and overall system behavior.
This role requires meaningful hands-on experience across the full application stack. Candidates should be comfortable working across front-end and back-end systems rather than specializing exclusively in one layer.
Responsibilities
- Develop, modify, and debug front-end and back-end application components.
- Implement user-facing features along with 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 effectively within unfamiliar repositories and understand existing application architecture.
- Diagnose failures involving application state, API contracts, authentication, persistence, networking, and deployment.
- Develop and evaluate software solutions across multiple programming languages.
- Translate complete coding implementations from one programming language into another while preserving intended functionality.
- Review AI-generated software solutions for correctness, completeness, performance, security, and maintainability.
- Identify technical issues and recommend appropriate improvements to application code and architecture.
- Validate solutions against functional and technical requirements.
- Apply strong engineering judgment when analyzing complex software-development problems.
