Mid Level Full-Stack Engineer

On a per-contract schedule, typically net-15 to net-30 from invoice submission rather than the weekly payouts some platforms offer. Confirm the exact terms in your contract, and ask your project contact directly if payment timing affects your cash flow.

Only for specialist roles: ML research, atmospheric modeling, bioinformatics, COBOL, and audit accounting positions require verifiable credentials, usually a PhD, master's degree, or 5+ years of professional experience. AfterQuery's domain screeners check credentials before confirming an assignment, so listing a degree without the matching experience won't get you through. Generalist reviewer roles have a lower bar but come up less often.

No, it's closer to academic research. Expect to write or verify complex proofs, solve advanced equations, or check the logic behind a model's step-by-step reasoning. The goal is teaching AI systems to reason deeply within your specific field.

For the top pay tiers, a PhD or current enrollment is usually expected. But the domain assessment is what decides it: if you can solve the problems, the degree becomes secondary.

Tasks here are scoped to STEM, not generic labeling. As a Mid Level Full-Stack Engineer, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to STEM) rather than following a one-size-fits-all rubric. If you don't have hands-on STEM background, this is likely not the right listing to start with.

Coding, JavaScript, and SQL are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.

This listing is posted at $80/hr, an hourly rate. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

You'll be taken to Afterquery's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

This specific role is open only to people based in the United States. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply.
