Position Overview
RecargaPay is looking for a Cyber Security Specialist to be a hands-on technical practitioner within our CSIRT (Computer Security Incident Response Team). This person will own the detection, response, and containment of security incidents across our payments platform — executing the full incident lifecycle, building detection logic, and driving automation to shrink response time in a cloud-native, high-volume transactional environment.

Key Responsibilities

• Own the full incident response lifecycle end-to-end: detection, triage, containment, eradication, recovery, and post-mortem.
• Develop and maintain playbooks, runbooks, and response procedures that keep response sharp and repeatable.
• Build and maintain detection and response automations (SOAR) to orchestrate workflows across tools and reduce manual toil.
• Operate and continuously tune the detection stack on Elastic (Elasticsearch/Kibana): queries, dashboards, alerts, and event correlation.
• Maintain the Elastic infrastructure on Linux.
• Manage endpoint detection and response via CrowdStrike (EDR), including proactive threat hunting and containment actions.
• Investigate and respond to incidents in AWS (CloudTrail, GuardDuty, IAM, VPC, and related services).
• Produce incident reports and MTTD/MTTR metrics that give leadership clear visibility into the security posture.
• Collaborate with engineering, infrastructure, and compliance teams to remediate vulnerabilities and reduce the attack surface.

Requirements

Technical Skills

• Solid hands-on experience in security incident response in complex, high-volume environments.
• Strong command of Elasticsearch/Elastic Stack for detection, threat hunting, and alert creation. Experience with AWS security — native security services and cloud log investigation.
