Note: Participation is on a project basis, not permanent employment.What You Will DoEach project presents unique challenges, and contributors may:Design innovative computational physics problems that replicate actual research workflows;Create programming challenges that necessitate Python solutions (utilizing libraries such as Numpy, SciPy, and Sympy);Ensure tasks are computationally demanding and cannot be resolved manually within a reasonable timeframe;Develop problems that require sophisticated reasoning in mechanics, electromagnetism, thermodynamics, and quantum mechanics;Base problem sets on genuine research obstacles or real-world applications from the field of physics;Verify solutions using Python and standard physics simulation libraries;Clearly document problem statements and provide validated answers.What We Are Looking ForThis role is ideal for physicists with Python experience who are interested in part-time, non-permanent engagements. Ideal candidates will possess:A degree in Physics (Theoretical, Experimental, or Computational) or a related discipline;Proficiency in Python for numerical validation, with familiarity in MATLAB, R, C, SQL, Numpy, Pandas, SciPy, or Stata being advantageous;A minimum of 2 years of professional experience in applied research or teaching;Experience with numerical simulation techniques;The capability to create problems that reflect real-world physics research workflows;Creative approaches to problem design across various physics domains;A solid understanding of physics modeling and approximation methods;Strong written English skills (C1+).Process OverviewApplication → Qualification Assessment → Project Assignment → Task Completion → PaymentProject Time CommitmentFor this project, expect to dedicate approximately 10–20 hours per week during active phases, based on specific project needs. This is an estimate and not a guaranteed workload for the duration of the project.Compensation DetailsContributors can earn up to $45 per hour, contingent upon their proficiency and contribution pace. Compensation may vary by project based on scope, complexity, and expertise required. Note that other projects may offer differing compensation levels based on their specific needs.
