• Knowledge of Vulnerability Assessment and Penetration Testing (VAPT) for infrastructure, network, web applications, and web services/API.
• Strong ability to multi‑task and perform under extreme pressure with tight deadlines.
• Meticulous planning skills and attention to detail.
• Ability to work independently as well as collaboratively within a team.
• Resilience in managing a reasonably high level of stress while maintaining effectiveness.
• Demonstrated drive, level‑headedness, and adaptability in dynamic environments.
• Excellent interpersonal and communication skills for engaging with internal and external stakeholders.
• All new hires are appointed on a two‑year contract in the first instance and will be assessed and considered for permanent tenure over time, based on performance.
