Note: The job is a remote job and is open to candidates in USA. Remote CoWorker is seeking a Senior Full-Stack Developer who can build fast and leverage AI tooling to deliver production-grade applications.

• Integrate open-source AI models into products—evaluating, deploying, and optimizing them for real use cases
• Solve ambiguous problems creatively and propose better approaches, not just execute tickets
• Own technical decisions, architecture, and code quality as a senior member of the team
