Kuwait
Contract
$35 per hour

What this opportunity involves Design original computational physics problems that simulate real physics research workflows. Create problems requiring Python programming to solve (using Numpy, SciPy, Sympy). Ensure problems are computationally intensive and cannot be solved manually within reasonable timeframes (days/weeks). Develop problems requiring non-trivial reasoning chains in mechanics, electromagnetism, thermodynamics, and quantum mechanics. Base problems on real research challenges or practical applications from physics practice. Verify solutions using Python with standard physics simulation libraries. Document problem statements clearly and provide verified correct answers. What we look for Degree in Physics (Theoretical, Experimental, or Computational) or related fields. Python proficiency for numerical validation. MATLAB, R, C, SQL, Numpy, Pandas, SciPy, domain-specific libraries, Stata or knowledge of any programming language can be equivalent. 2+ years of professional experience: applied, research, or teaching experience is applicable. Experience with numerical simulation methods. Ability to design problems that mirror real physics research workflows. Creative thinking in problem design across diverse physics areas. Familiarity with physics modeling and approximation techniques. Strong written English (C1+). How it works Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid Project time expectations For this project, tasks are estimated to require around 10–20 hours per week during active phases, based on project requirements. This is an estimate, not a guaranteed workload, and applies only while the project is active. Compensation On this project, contributors can earn up to $35 per hour equivalent, depending on their level and pace of contribution. Compensation varies across projects depending on scope, complexity, and required expertise. Please note that other projects on the platform may offer different earning levels based on their requirements.
