Company

hirify.global AI is building the next generation of frontier models that power Copilot and other large-scale AI experiences.

What you will do

• Design evaluations of advanced model capabilities and use them to drive rapid, high-signal iteration loops.
• Work with vendors to produce high quality evaluation and training data.
• Build data pipelines to produce high quality evaluation and training data.
• Build data flywheels to hill-climb on model weaknesses, using data from various surfaces where our models are deployed.
• Ensure optimal quality, quantity and coverage of data across our post-training stages.
• Run post-training experiments and ablations to produce models that climb our evals.

Requirements

• Bachelor’s Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.
• Have deep experience with LLMs, either training them or applying them in production.
• Have developed production-scale data pipelines for synthesizing, curating, or processing large quantities of data.
• Can design, run, and interpret large-scale ML experiments with careful statistical and empirical reasoning.
• Possess strong generalist engineering and mathematical skills.
• Have clear written and verbal communication, and the ability to collaborate effectively with researchers, engineers and other disciplines.

Nice to have

• Demonstrated SOTA results in any area of large-scale training, inference, or evaluation.
