- Background in mentoring or training other engineers/testers is highly advantageous.
- Exposure to analytics testing, data modelling, or working with analytical products.
Soft Skills
- Strong communication skills - confident in providing constructive feedback and driving improvement.
- Comfortable presenting solutions and testing strategy to stakeholders.
