Senior Full-Stack & Cloud Engineer (Contract - 6 months)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Full-Stack & Cloud Engineer (Contract - 6 months) based in United States. This role offers the opportunity to take end-to-end technical ownership of an internally developed web application and transform it into a secure, reliable, and maintainable production solution. You will assess an existing AI-assisted codebase, identify technical debt and security risks, and strengthen the architecture without unnecessarily rebuilding effective components.

You will establish sustainable engineering standards and practices while continuing to develop features as business needs evolve. The role also provides significant autonomy, with responsibility for reliability, performance, cost, and long-term maintainability. It is well suited to an experienced engineer who enjoys solving complex problems and applying sound engineering judgment to AI-assisted development.
