Member of Technical Staff (North Modelling, Evals)

• This role is about being the voice of North inside modelling. You will build the evaluation systems, feedback loops, and applied modelling workflows that make sure model progress translates into better product outcomes for North users
• You will work closely with North product teams, customer-facing teams, and modelling teams to define what “good” means across the product surface, turn real usage and product direction into high-quality evals, and use those evals to guide model selection, patches, and regular model updates
• This is neither a pure research role nor a conventional product engineering role
• Own the eval strategy for North: define what we need to measure across agent workflows, tool use, enterprise knowledge work such as deep research, document creation or editing, and other human-AI interactions
• Build high-quality evals from the realities of the product: user feedback, production failures, privacy-preserving usage logs, internal dogfooding, customer needs, and forward-looking product goals
• Create systems that continuously turn what North is learning from users, customers, and feature teams into evals, so measurement keeps pace with the product rather than becoming a static benchmark
• Be the voice of North inside modelling: extract clear insight from eval results, customer-derived data and product context, then turn model failures, capability gaps, and North-specific needs into actionable recommendations for the central modelling teams

• It is a rigorous applied MLE role for someone who cares deeply about measurement, model behavior, and real-world product quality
• You should be excited by the craft of building careful evals: evals that capture messy agentic workflows, reflect actual customer needs, resist superficial benchmark hacking, and provide useful signal for where the product and models need to go next
• You care about making AI systems genuinely useful in real enterprise settings, not just better on abstract benchmarks
• You are comfortable working close to users and product teams, while translating messy qualitative signals into measurement that other modelling teams can act on
• You have improved LLM-powered, agent-powered, or AI-product systems through evals, feedback loops, data curation, prompting, model adaptation, or model selection
• You care deeply about evaluation as a craft: representative tasks, precise rubrics, clean data, failure analysis, regression tracking, and knowing when a metric is giving false confidence
• If some of the above does not line up perfectly with your experience, we still encourage you to apply
• You are self-directed, practical, and motivated by open-ended problems where the right answer requires both technical depth and product understanding
• You have strong applied MLE judgment and can reason clearly about model behavior, eval validity, product outcomes, and production tradeoffs
