Blue Team Specialist – Threat Hunting & Anomaly Detection
About CloudWalk:
We are not just another fintech unicorn. We are a pack of dreamers, makers, and tech enthusiasts building the future of payments. With millions of happy customers and a hunger for innovation, we're now expanding our neural network - literally and metaphorically.
We are not your traditional security team drowning in endless policies and red tape. At CloudWalk, security is fast, smart, and hacker-minded—we outthink threats before they even become threats.
Our mission? Protect our high-speed, high-impact infrastructure without slowing it down. We don’t just monitor logs and send alerts into the void; we hunt threats, automate responses, and fortify systems at scale.
If you enjoy breaking things just to understand how they work (and then fixing them better than before), keep reading.
The Role:
We are looking for a technical powerhouse to defend our Linux-heavy infrastructure, detect anomalies before they cause trouble, and turn attackers' tactics against them.
You’ll be hunting threats, writing detection rules, tweaking security tools, and breaking bad (but legally, of course).
What You Will Be Doing:
Threat Detection & Incident Response
Hunt for anomalies, backdoors, and sneaky persistence mechanisms—because prevention alone is a fairy tale.
Optimize and operate XDR (Extended Detection & Response) to track down real threats.
Use YARA to create custom rules that actually detect useful stuff, not just random noise.
Linux Security & Hardening
Fortify Linux systems against attacks while keeping performance slick.
Work with OSSEC (Host-based Intrusion Detection) and similar tools to spot and stop threats in real time.
Conduct forensics on compromised machines—because knowing 'how' is just as important as stopping 'who.'
Vulnerability & Compliance Monitoring
Use Nessus (or other vulnerability scanners) to hunt and eliminate weak points.
Monitor logs, detect weird patterns, and respond before things get ugly.
Leverage AI and Automation: Explore and deploy cutting-edge AI tools and frameworks to enhance productivity, automate processes, and innovate at scale.
What We Are Looking For:
Deep expertise in IAM, security governance, and compliance enforcement.
Strong knowledge of threat detection, incident response, and risk mitigation.
Ability to automate security operations and drive efficiency.A problem-solving mindset, balancing security and agility.
AI Enthusiast: Advanced proficiency in using AI tools to accelerate development and enhance solutions.
Global Communicator: Fluent English skills to collaborate effectively with a multinational team.
What We Offer:
Deep experience with Linux security—you know how attackers think and how to stop them.
Threat detection mindset—you love investigating logs, processes, and binaries like a cyber Sherlock Holmes.
Experience with XDR, OSSEC, YARA, Nessus, or similar tools—if it detects threats, you probably love it.
Some Windows security knowledge is a plus—but let’s be real, your heart belongs to Linux.
Ability to automate your own work—because manually parsing logs is for people who like suffering.
The Future We See
CloudWalk is pushing the boundaries of security:
AI-driven threat hunting to stay ahead of attackers.
Automated response playbooks that kick in before humans even wake up.
Security that scales without friction—because we’re here to protect, not slow down.
So, are you ready to join the hunt? Come break, fix, and fortify with us. 🚀
Join us at CloudWalk, where we’re not just engineering solutions; we’re building a smarter, AI-driven future for payments—together.
By applying for this position, your data will be processed as per Cloudwalk's Privacy Policy that you can read here in Portuguese and here in English.
