You may be asked to prepare, clean, and maintain lab equipment and log readings and results. Your responsibilities may also include performing basic analyses of samples and recording results accurately.

Attention to detail, strong organizational skills, and effective teamwork are essential soft skills for this role. These skills ensure accurate results, maintain lab safety standards, and support smooth laboratory operations.
