If you're ready to do your best work, at scale, with purpose — this is your place. 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. Hands-on experience with CrowdStrike or an equivalent EDR. Workflow automation and orchestration using a SOAR or automation platform. Strong Linux proficiency (administration and hardening). Knowledge of BTT (Boitatá), Apura's threat intelligence tool. Experience with mTLS certificate lifecycle management and AWS ACM (Certificate Manager). Fluency with frameworks such as MITRE ATT&CK, NIST IR, and standard incident taxonomies. Soft Skills Technical depth: owns a complex domain (CSIRT tooling and detection engineering) and drives improvements without needing direction. Independent judgment under pressure: makes sound containment decisions in fast-moving incidents with incomplete information. Cross-functional influence: translates security findings into clear, actionable guidance for engineering and infrastructure partners. Documentation discipline: keeps playbooks, runbooks, and post-mortems current so the team can operate without heroics. Continuous improvement mindset: proactively identifies detection gaps and proposes measurable improvements to MTTD/MTTR. Nice to Have Background in financial services, fintech, or other high-volume transactional environments. Scripting (Python / Bash) for automation and tool integration. Certifications such as GCIH, GCIA, GCFA, OSCP, or equivalent. Experience with compliance requirements (PCI-DSS, LGPD). Benefits Competitive and market-aligned salary. Remote work — wherever you are, you’re part of the team! Home office allowance through a monthly deposit in the RecargaPay app. Health and dental plans with no co-pay. Life insurance. Flexible meal allowance (via Flash). TotalPass membership to take care of your health.
