Security Engineer (Pentest)
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.
This is not a traditional pentesting role. At CloudWalk, you’ll go beyond running scans or writing reports. You’ll break into systems, exploit real weaknesses, and then engineer automations and agents to make sure those classes of vulnerabilities never come back. Your work will directly shape how CloudWalk defends itself at scale, turning offensive security knowledge into defensive engineering.
You’ll be part of a team that blends red teaming, mobile/web pentesting, and security automation. If you enjoy moving fast, exploiting hard problems, and coding the solutions, this role is for you.
What You'll Do
Become a Vulnerability Slayer: Support our efforts in making repetitive vulnerability scanning and remediation a thing of the past. You will help manage and improve automated workflows to identify and address vulnerabilities. You will also manually pentest our applications and systems to identify and mitigate potential issues.
Automate the Grind: Build and improve security automations and agents that reduce repetitive scanning and streamline remediation across our environment.
Champion Security by Design: Collaborate with our security and engineering teams to understand their needs and help translate them into effective security automations.
Code with Security in Mind: Participate in code reviews to learn how to identify potential security vulnerabilities and recommend secure coding practices to developers.
Innovate with LLMs: Experiment with LLMs and agent-driven frameworks to create new ways of detecting, classifying, and mitigating vulnerabilities in real time.
What We're Looking For
Strong knowledge of common vulnerabilities, exploitation techniques, and secure coding best practices.
Experience with mobile pentesting (Android/iOS), including relevant tooling and methodology.
Hands-on experience with security automation (Python, Go, or similar).
Bonus: Experience leveraging LLMs/agents for security tasks.
Proficiency in at least one scripting language (Python, Go, or similar).
Familiarity with cloud security principles (AWS, GCP, or Azure).
Understanding of CI/CD pipelines and how to embed security checks into them.
Excellent communication and collaboration skills to work effectively with engineering teams.
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.
