Scientific Coding Expert — Python Problem Authoring (rustLabs Experts)

rustLabs Experts lists scientific coding as one of its open roles, covering physics, chemistry, biology, mathematics and materials. The work is writing problems, not solving them. You produce one main scientific coding problem and at least three connected sub-problems from your own field, then supply a verified Python solution with unit tests and test cases that separate correct answers from wrong ones. That last part is the point. A problem with no objective pass-or-fail check is useless as training data, so the tests carry as much weight as the question. rustLabs calls this shape Build. A second expert reproduces each task before it ships, work runs a few hours per task, and payment is per accepted task. There is no starter exam for this role. After a one-minute application, one short form asks for your subject, degree, publications link and available hours. Existing account holders apply from a role page that sits behind a login. The public pages give no rate, no country restriction, no close date and no headcount.

rustLabs advertises $20–100+/hr across all six of its fields and says each role states its pay before you apply, but this role's public card shows no figure. Payments go through Dots within 30 days of acceptance. No prior annotation experience is needed.
