Member of Technical Staff, Frontier AI

Job Title: Member of Technical Staff, Frontier AI Job Type: Full time Location: Remote The Role We’re hiring a Member of Technical Staff (MTS) to act as a technical owner operating at the intersection of research, data, and real-world AI systems. This is a hands-on role focused on improving model and system performance through rigorous evaluation, failure analysis, and iterative development. You’ll work closely with researchers, domain experts, and operators to ensure that experimental work produces clean, defensible research signal—and that this signal translates into meaningful improvements in deployed systems. What You’ll Do Own research and evaluation initiatives end-to-end: problem framing, data design, quality calibration, and signal validation. Design ML-oriented data systems, including task definitions, annotation schemas, rubrics, incentives, and pipelines optimized for downstream model performance. Analyze model and system failures to identify root causes, edge cases, and opportunities for improvement. Translate ambiguous, real-world behavior into structured evaluation frameworks and new data categories. Work closely with researchers and domain experts to calibrate quality early and continuously raise the signal bar. Iterate rapidly on evaluations, datasets, and feedback loops to improve system performance. Act as a quality gate: block claims, pause work, or force scope changes when signal strength or data integrity is insufficient. Partner with cross-functional and client-facing teams to translate research progress into clear, credible narratives grounded in evidence. Identify gaps in data or evaluation coverage and recommend where to invest, iterate, or stop based on learnings and impact. What We’re Looking For Strong judgment around research signal quality and when work is (or is not) ready to be externalized. Experience designing ML-oriented datasets, evaluation frameworks, and QA processes. Ability to translate messy, real-world system behavior into s
