Overview

AfterQuery hires experienced engineers to create long-horizon coding tasks that mirror real engineering work in sizable codebases. You will turn bugs, features, regressions and migrations into prompts that force an AI coding agent to investigate before it edits. Each task needs Docker packaging and a deterministic test suite that grades solutions the way a careful reviewer would. The role also calls for a private codebase you own, since every task starts from real code rather than a toy example.

What You'll Do6

  • Turn real bugs, feature requests, regressions and migrations from large codebases into long-horizon tasks.
  • Write prompts that require a coding agent to trace dependencies, inspect multiple files and carry out a complex fix.
  • Create deterministic tests and review rules that confirm correctness and catch regressions.
  • Design grading criteria that block shortcut solutions and reward hacking.
  • Package each task in Docker so builds and runs stay consistent across environments.
  • Document task setup, expected behavior and test commands for reviewers.

Requirements8

  • Proficiency in at least one modern language such as JavaScript, TypeScript, Java, Go, Rust, C/C++ or Python.
  • History of architecting or maintaining large, complex software projects.
  • Hands-on use of Docker or another container tool.
  • Strong technical writing, documentation and testing skills.
  • A large private codebase you own and can use as source material for tasks.
  • Experience running coding agents through long tasks.
  • Code review, test authoring or production/open-source maintenance background.
  • Familiarity with AI evaluation, rubric-based grading, data grading or prompt writing.

Who Should Apply

The role suits an engineer who has shipped or maintained a substantial private codebase and can turn real defects into testable tasks. You should pair strong Docker habits with clear technical writing and enough review experience to judge solutions the way a senior reviewer would.

Salary Insight

The posted rate is $85.00/hr. Weekly hours and contract length stay open in the listing, so clarify both before you commit. That rate lines up with senior contract work that expects independent task design and review.
