LILT is seeking a AI Benchmark Engineer - Native Language Specialist with native fluency in Czech. In this role, you will design, build, and validate multilingual software benchmarks for large language models, creating high-signal tasks that test a model's ability to handle multilingual environments without relying on English translation.
What You'll Do
- Task Engineering: Evaluate the performance of Coding Agents.
- Asset Creation: Build realistic task environments using datasets and files in your native language.
- Prompting & Translation: Identify failure points where AI does not work correctly in your native language.
- Implementation & Verification: Support the development of robust solutions and write highly reliable, deterministic verifier scripts.
- Calibration & Execution: Analyze execution logs and calibrate task difficulty using standard Terminal-Bench run configurations against various model tiers.
- Quality Assurance: Participate in a rigorous, 4-layer human quality control process alongside automated LLM-based checks to ensure fairness, grammatical accuracy, and benchmark integrity.
What We're Looking For
- 5+ years of industry experience in software engineering.
- Proven track record at leading technology companies and/or graduation from top-tier engineering universities.
- Native or near-native fluency in Czech, with a deep understanding of its grammar, register, and phrasing rules. High English proficiency.
- Strong proficiency in Python, standard shell scripting, and data processing.
- Extensive experience with Terminal/CLI-based development workflows and a working familiarity with coding agents.
- Deep technical understanding of multilingual text processing pitfalls including encoding/decoding robustness, Unicode normalization, locale-dependent conventions, text I/O, toolchain interoperability, and safe string operations.
