What this role is all about
 

Infobip’s Corporate Security team is looking for a new member to work in the Anti-Fraud team, keeping us and our clients on the safe side! 

As a Cyber Security Engineer, you will play a key role in identifying and preventing fraudulent activity across customer platforms. Your primary responsibility will be to monitor customer traffic and transactional records to detect threats such as account takeovers, payments fraud, BEC/CEO fraud, and other risks. Upon identifying fraudulent traffic, you will take immediate action to cancel it and prevent further processing. 

You will resolve queued traffic and continuously observe patterns to uncover unauthorized connections and fraudulent accounts. Maintaining and refining fraud analysis models will be essential to improving the efficiency and accuracy of our detection systems, while ensuring the confidentiality of all information gathered during investigations. 

By analyzing account behavior and traffic trends, you will identify emerging fraud patterns and recommend platform or system improvements to mitigate future risks. You’ll also evaluate and suggest new software tools to enhance fraud detection, prevention, and reporting capabilities. Additionally, you will be responsible for generating suspicious activity reports and incident documentation for clients. 

What You'Ll Do

• Monitor near-real-time job queues to identify and triage high-risk events (e.g. large campaigns). 
• Track relevant mail groups for cases involving high volumes of spam messages. 
• Respond to security alerts and tag the spam team on the fraud channel when spam is detected. 
• Analyze data from multiple sources (e.g. logs) as part of cyber investigations. 
• Observe customer events to detect and flag fraudulent activity such as account takeovers, payments fraud, unauthorized access, and fraudulent accounts. 
• Investigate confirmed cases of forgery, account takeover, and system misuse within customer accounts. 
• Escalate verified fraud incidents to appropriate stakeholders (e.g. Account Managers, Site Reliability Engineers). 
• Monitor regular user activity and traffic to establish behavioral baselines and identify anomalies. 
• Support education efforts for sales teams and clients to help prevent victimization. 
• Propose changes to system architecture or recommend security measures to prevent unauthorized access or misuse. 
• Contribute to the automation of internal processes to improve team efficiency. 

What makes you a strong fit

• Preferably an educational background in Computer Science, IT Engineering, IT security, or a related field. 
• Minimum 3 and preferably 5+ years of relevant experience, preferably in a fast-paced international environment. 
• General IT/computer competency – cybersecurity engineers use technology to conduct research, correspond with clients and colleagues, leverage data, and monitor activity. 
• Advanced English level, speaking and writing. 
• Available to work following a hybrid work model per Company policy.
