Advanced Coding Expert - Remote Contract
Listing checked September 11, 2026 · pay as published by AfterQuery
Overview
AfterQuery hires experienced engineers to create long-horizon coding tasks that test and train advanced coding agents. You will draw real bugs, features, regressions and migrations from a substantial codebase you own, then shape them into prompts that demand genuine investigation from an agent. Each task needs a Docker setup that builds and runs the same way every time. You also design test suites and review rules that separate correct work from shortcut solutions. The contract runs 30 hours per week, remote, with pay from $70.00 to $100.00 per hour.
What You'll Do6
- 1Turn real engineering problems from large codebases into long-horizon tasks that a coding agent must solve.
- 2Write prompts that force an agent to inspect multiple files, trace dependencies and handle complicated execution steps.
- 3Create deterministic test suites that confirm correct behavior, catch regressions and block reward-hacking answers.
- 4Define review criteria that grade a solution the way a careful human reviewer would.
- 5Package every task with Docker so builds, tests and runs stay reproducible across environments.
- 6Use your own private codebase as the source for tasks, keeping the material substantial and complex.
Requirements9
- 1Proficiency in at least one modern language such as JavaScript, TypeScript, Java, Go, Rust, C, C++ or Python.
- 2Experience architecting or maintaining large, complex software projects.
- 3Hands-on work with Docker or similar containerization tools.
- 4Strong technical writing, documentation and testing skills.
- 5Access to a large, private codebase you own and can use to author tasks.
- 6Experience using coding agents on long tasks.
- 7Background in code review, test authoring or maintaining production systems.
- 8Background in open-source maintenance.
- 9Exposure to AI evaluation, rubric grading or prompt writing.
Who Should Apply
Ideal candidates bring senior engineering depth, a large private codebase they control, and comfort with Docker-based workflows. They have used coding agents on lengthy tasks and can write prompts, tests and review standards that hold up under scrutiny. The role fits engineers who enjoy code review, test authoring and documenting complex systems, plus those with exposure to AI evaluation or rubric grading. Engineers who lack a substantial private codebase of their own, or who have only worked on small, single-file projects, will find the role a poor match. Candidates often lose fit points when their prompts are too simple, their container setup is missing, or they skip the required assessment.
Salary Insight
AfterQuery lists $70.00 to $100.00 per hour for this contract. That range sits at the senior end for AI task authoring work, and the 30-hour weekly commitment gives you steady project volume without a full-time schedule.
