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.
