Full Stack Engineer

AfterQuery is hiring software engineers to author original coding tasks based on real codebases, used to evaluate and train advanced AI coding agents. You'll connect one of your own private codebases and turn a real engineering problem from it into a task: a clear, maintainer-style issue, a hidden test suite, and a reference solution. Every submission is validated automatically before it's approved, so the ideal candidate is someone who can write a problem a strong engineer would recognize as real work, and a test suite that verifies a solution the way a careful reviewer would.Why ApplyExceptional Pay: $150/hour, fully remote, on your own scheduleReal Engineering: Work from your own codebases on problems a strong engineer would recognize as real workStartup Exposure: Contribute directly to frontier AI evaluation with a YC-backed research labResponsibilitiesConnect a substantial private codebase of your own to author tasks againstAuthor maintainer-style issues, hidden test suites, and reference solutionsEnsure every task passes automated validation before approvalRequired QualificationsProfessional software engineering experience with substantial private codebasesStrong testing instincts: able to write suites that verify solutions the way a careful reviewer wouldClear technical writingCompany DescriptionAfterQuery is a research lab investigating the boundaries of artificial intelligence through novel datasets and experimentation.
