Voodoo ищет ML-инженера для отдела Engineering & Data в Финляндии. Ваша роль — взять полную ответственность за проекты от идеи до релиза, строить и поддерживать ML-конвейеры, работать с данными и моделями на стыке Data Science и Backend.

Требуется 5+ лет опыта, глубокие знания Python, PyTorch и AWS, умение оптимизировать обучение и работать в кросс-функциональной команде. В должность входит участие в разработке производственных ML-систем и поддержке инфраструктуры.

Qualificações

  • Опыт от 5 лет в ML-инженерии или аналогичной роли.
  • Опыт владения end-to-end ML: постановка задачи, базовые линии, эксперименты, развёртывание.
  • Глубокие знания Python для ML конвейеров (предобработка, тренировка, валидация, конфиги).
  • Умение реализовывать training mechanics, кастомные шаги и метрики, эффективную загрузку данных.
  • Практический опыт обучения и оценки моделей с scikit-learn, LightGBM и PyTorch.
  • Опыт оптимизации памяти на этапах препроцессинга и обучения моделей.
  • Опыт гиперпараметрического поиска, трекинга экспериментов и воспроизводимых тренингов.
  • Опыт работы с AWS, понимание масштабирования, надёжности и безопасности.

Responsabilidades

  • Полная ответственность за проекты от идеи до продакшн-релиза, включая объем feature-ов, тайм-менеджмент и архитектуру.
