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.

Are you passionate about security and eager to build a career in automation and problem solving? Do you want to strengthen defenses by building reliable pipelines and tooling? If so, we invite you to start your journey with our team as a Security Engineer focused on security automation

In this role, you will be a key contributor to our security automation strategy. Under the guidance of senior engineers, you will help design, develop, and maintain automations that streamline vulnerability management, log ingestion, enrichment, and alerting, empowering the team to work faster and smarter.

What You'll Do

  • Automate Workflows: Build and maintain automated workflows for blue-team operations, from data ingestion and normalization to correlation, alerting, and reporting, using scripts, services, and containerized pipelines.
  • System Hardening: Codify and automate hardening guidelines and best practices across operating systems, applications, and cloud platforms, ensuring repeatable, auditable baselines.
  • Collaborate Across Teams: Partner with security, engineering, and IT to integrate data sources and APIs, automate evidence collection for investigations and control verification, and ensure secure-by-default configurations aligned with internal security standards.
  • WAF Management: Define, automate, and monitor WAF rules as code to protect applications against web attacks, including safe rollout, testing, and telemetry for performance and compliance.

What We're Looking For

  • Strong desire to learn and demonstrate skill in at least one scripting language (Python, TypeScript, or similar) to build production-ready automations and integrations.
  • Analytical problem-solving skills and attention to detail for debugging, tuning alerts, and measuring coverage.
  • Effective communication and ability to work as part of a collaborative team.
  • Familiarity with EDR platforms (e.g, CrowdStrike, Defender ATP)
  • Basic understanding of SIEM concepts (log ingestion, parsing, alerting, dashboards, correlation rules) with pipeline reliability.

Join us at CloudWalk, where we're not just engineering solutions; we're building a smarter, AI-driven future for payments—together.
