Research Engineer, Benchmarks

About the Role Join a small, technical team working on AI evaluation and reinforcement learning infrastructure. You will design and build rigorous benchmarks for assessing AI agents on realistic, domain-specific workflows, helping research and engineering teams understand how well agents perform in practice. What You'll Do Design, implement, and maintain benchmarks for evaluating AI agents on domain-specific tasks. Work with subject-matter experts to translate real workflows into practical tasks and evaluation criteria. Build reliable infrastructure to run models and agents against benchmark tasks at scale. Develop metrics and analyses to assess benchmark difficulty, reliability, and failure modes. Validate benchmark results against real-world evaluations and user needs. Write clear technical documentation and reports that explain methods and results. What We're Looking For Two to four years of experience in software engineering, machine learning engineering, or research, including at least two years building AI benchmarks, evaluation infrastructure, or agent environments. Hands-on experience designing and running evaluations or benchmark environments for AI agents or large language models. Strong proficiency with Python, Docker, and Linux, including building and operating reliable infrastructure. Experience developing metrics, statistical analyses, or validation studies for evaluation systems. Experience collaborating with subject-matter experts and understanding workflows across technical or business domains. Strong technical writing, careful attention to detail, and the ability to work independently in an early-stage, fast-moving environment. Research publications or technical writing on benchmarking, model evaluation, or failure modes are beneficial. Experience with reinforcement learning pipelines or public benchmark projects is also useful. Compensation & Benefits Base salary: $100,000 to $170,000 USD annually. Visa sponsorship is available. Location On-site in Singapore, Singapore.
