AI Benchmark Engineer | Native Language Specialist - Dutch - Remote

About The Opportunity

We are building a rigorous, verifiable evaluation suite of Terminal-Bench tasks designed to test the limits of large language models on multilingual software challenges. Our goal is to measure multilingual robustness across prompt language effects, non-English data processing, and complex locale/encoding edge cases in terminal workflows.

We are seeking experienced native-speaking software engineers to design, build, and validate these benchmarks. You will create high-signal, high-quality tasks that genuinely test a model's ability to handle multilingual environments without relying on English translation crutches.

Note this is a remote, freelance opportunity

What You’ll Deliver

• Task Engineering: Evaluating Coding Agents.

• Asset Creation: Build realistic task environments using datasets and files in your native language. Crucially, these assets must remain in the target language to genuinely measure multilingual handling.

• Prompting & Translation: finding failure points where AI does not work, in your native language

• Implementation & Verification: Support the development of robust solutions (reference implementations) and write highly reliable, deterministic verifier scripts (using rubric-based judging only when strictly necessary).

• Calibration & Execution: Analyze execution logs and calibrate task difficulty (Easy to Very Hard) using standard Terminal-Bench run configurations against various model tiers (Haiku, Sonnet, Opus).

• Quality Assurance: Participate in a rigorous, 4-layer human quality control process (creation, human review, calibration review, and audit) alongside automated LLM-based checks to ensure fairness, grammatical accuracy, and benchmark integrity.

Qualifications

• Experience: 5+ years of industry experience in software engineering.

• Background: Proven track record at leading technology companies and/or graduation from top-tier engineering universities.

• Language: Native or near-native fluency, with a deep understanding of its grammar, register, and phrasing rules. High English proficiency.

• Technical Stack: Strong proficiency in Python, standard shell scripting, and data processing.

• Workflow: Extensive experience with Terminal/CLI-based development workflows and a working familiarity with coding agents.

• Domain Expertise: Deep technical understanding of multilingual text processing pitfalls, including:

  • Encoding/decoding robustness and Unicode normalization.

  • Locale-dependent conventions (collation, casing, non-Gregorian dates).

  • Text I/O, toolchain interoperability, and safe string operations.

  • (For specific languages) Bidirectional/RTL handling, font fallbacks, and rendering/typography in UI or artifacts.

What to Consider Before Applying

• Not ideal as a full time job or primary income source. Work availability fluctuates with project demand, making this better suited as a supplemental income stream. As a 1099 contractor, you won't receive benefits such as health insurance, paid time off, or retirement contributions, and hours are not guaranteed.

• Requires reliable availability and commitment. Once you accept a task, we expect quality work and on-time delivery. Most tasks require a minimum of 2 hours per day or 15-20 hours per week. If your schedule is unpredictable, this may not be the right fit.

• Geographic restrictions may apply. We cannot engage contractors in regions subject to international embargo or sanctions. As a 1099 contractor, you are solely responsible for your own tax obligations. We recommend consulting a tax professional before engaging.
