WHAT WE ARE LOOKING FOR IN YOU?
Professional Experience:
Minimum of 3 years in application security, bot defence, or eCommerce fraud prevention, with demonstrated ability to protect public-facing digital platforms against automated abuse, credential stuffing, and scraping campaigns.
Tool Proficiency:
Hands-on experience with at least one enterprise-grade bot mitigation solution (e.g., Cloudflare, Akamai, PerimeterX, DataDome), including configuration, monitoring, and rule tuning capabilities.
Technical Knowledge:
Strong grasp of core web protocols and defence mechanisms, including HTTP/S behaviour, user-agent spoofing, CAPTCHA challenges, JavaScript fingerprinting, and behavioural detection techniques. Ability to differentiate legitimate traffic from evasive bot patterns.
Architectural Awareness:
Understanding of web application stacks, client-server interactions, and integration points between bot defence tools and underlying infrastructure such as CDNs, WAFs, and load balancers.

HOW WILL YOUR DAILY JOB BE?
Bot Traffic Monitoring and Analysis:
Continuously oversee bot defence platforms to identify malicious automated traffic, account abuse attempts, scraping activity, and evolving bypass techniques, ensuring round-the-clock visibility and awareness.
Dynamic Rule Tuning and Threat Adaptation:
Regularly update detection logic, challenge mechanisms, and mitigation rules based on threat intelligence, anomaly patterns, and observed bot behaviours—minimizing false negatives while reducing false positives and business disruption.
Cross-Functional Collaboration:
Partner with fraud prevention, DevOps, and digital experience teams to align mitigation strategies with platform requirements, customer experience expectations, and evolving eCommerce business goals.
Impact and Effectiveness Evaluation:
Track bot trends, success rates of attacks, and defence efficacy. Conduct root cause analyses of bypasses or misclassifications and deliver actionable recommendations to enhance protective posture.
Business-Friendly Implementation:
Ensure that bot mitigation techniques (e.g., CAPTCHAs, rate-limiting, fingerprinting) are SEO-compliant, accessible to all users, and optimized to avoid interfering with legitimate customer journeys and conversion flows.
