- Evaluate and select models for different use cases (accuracy, speed, cost).
- Write clean, testable, and maintainable code following solid principles.
- Participate in system design, architecture decisions, and technical reviews.
- Mentor junior engineers and contribute to a strong engineering culture.
Your skill and experience:
- Bachelor's degree in Computer Science or equivalent practical experience.
