Now We are looking for a Operational Security Engineer to run and continuously improve day-to-day security operations.
This role focuses on security alerts handling, phishing response, vulnerability coordination, and employee-facing security requests . You will focus on clarity, consistency, and visibility of security operations.

What You Will Be Doing:

• Design and implement security controls integrated into CI/CD pipelines

• Build and operate infrastructure security guardrails (Terraform, cloud, Kubernetes)

• Own security tooling as products (architecture, reliability, lifecycle)

• Implement audit logging, change tracking, and security evidence generation

• Design and evolve vulnerability management foundations (inventory, scoping, correlation)

• Define and enforce infrastructure security baselines

• Work with compliance teams to support audits (e.g., PCI DSS) through technical evidence

• Collaborate with SOC and operational teams to ensure controls are usable in practice

About You:

• Strong experience with CI/CD systems (GitHub Actions, GitLab CI, Jenkins, etc.)

• Infrastructure as Code (Terraform or similar)

• Cloud platforms (AWS, GCP, Azure)

• Container and Kubernetes security concepts (Falco, Trivy, etc.)

• Logging, auditability, and change tracking

• Understanding of vulnerability management fundamentals (CVEs, scanners, remediation, validation)

Nice to have:

• Runtime security and drift detection

• Secret scanning and prevention

• Experience building internal security tooling

• Exposure to compliance frameworks (PCI DSS, SOC 2, ISO 27001)

• Developing experience (Python, Go, etc.)

What We Offer:

• Remote-first, trust-based culture. Work from the place that works best for you. No mandatory office days, no attendance trackers. In some locations, we provide offices or coworking spaces, but the choice is yours.

• True flexibility. We do not fix you to a 9-to-5 schedule. You can adjust your working hours when needed, as long as your day stays productive and in sync with the team.

• Extra time off. Your birthday is a holiday here. Add to that 10 personal days each year, seven sick days without paperwork, and extra time to enjoy Christmas and New Year. Time to rest is part of the deal.

• Work that matters. Our mission is to build a digital world that is secure, accessible and inclusive for everyone. From fighting fraud to making online services easier and safer to use, your work will have a real impact on how people experience trust online.

• Compensation. We offer fair and transparent pay, benchmarked to the market.

• Truly global. We work across continents and time zones, with teammates and customers from all over the world. You will run campaigns that cross borders, cultures, and languages, and see your ideas land worldwide.

• Growth built in. Clear goals, open feedback and personal development plans. We support your progress with learning opportunities and by covering role-specific events, from design conferences to marketing forums.

• Team offsites. Sometimes just Slack is not enough. That is why we meet in person a few times a year. Trips are fully covered, so you can meet, collaborate, and recharge together.

• Getting you set up. We make sure you have access to the tools and hardware you need to do your work well.

• Friendly by design. Our logo is a dog for a reason. We keep things human, open and kind. We welcome individuality, quirks and different perspectives, because that is what makes our work smarter and more fun.
