What You Will Be Doing

As a Cyber Security Officer, your primary focus will be on Application and Cloud Security, while also supporting the broader cybersecurity posture of the organization. You will work closely with Developers and the Platform Teams (DevOps) to embed security into all stages of software delivery and infrastructure operations. Ensuring Flo maintains a secure, compliant, and resilient environment as it grows.

Secure Development & Cloud Practices

• Collaborate with developers to embed secure coding practices and conduct code reviews for high-risk features.
• Conduct threat modeling and security architecture reviews for cloud-native apps and microservices.
• Integrate security scanning tools (SAST, DAST, SCA) into CI/CD pipelines.
• Collaborate with the Platform Team (DevOps) to secure containerized workloads (e.g., Docker, Kubernetes), infrastructure-as-code, and serverless applications.
• Work with the Platform Team to secure configuration across AWS accounts, including IAM, encryption, and network controls.
• Implement and manage Web Application Firewalls (WAFs) to protect applications from OWASP Top 10 vulnerabilities and other common attacks.

Security Standards, Compliance & Governance

• Support the IT Security Manager in maintaining and aligning with ISO 27001, SOC 2, and PDPA requirements.
• Assist with external audits and maintain documentation of security controls, asset inventory, and risk assessments.
• Work with the IT Security Manager to implement Zero Trust principles, including strong identity access management and least-privilege enforcement.
• Help define and maintain internal security policies, procedures, and training programs.

Threat Detection & Incident Response

• Monitor and investigate alerts using SIEM platforms, IDS/IPS, and cloud-native security tools (e.g., AWS GuardDuty, Security Hub).
• Support response to security incidents, including containment, recovery, and post-incident analysis.
• Maintain incident response plans, develop playbooks, and contribute to tabletop exercises.
• Coordinate or assist with penetration testing and vulnerability assessments, both internally and with third-party vendors.

Device, Identity & Endpoint Security

• Support Mobile Device Management (MDM) tools and endpoint protection to ensure device compliance.
• Enforce secure configurations on employee laptops and mobile devices through policy-based controls.
• Manage access controls across cloud services and SaaS tools using SSO, MFA, and RBAC.
• Support security awareness efforts and employee training to reduce human risk.

Security Innovation & Continuous Improvement

• Stay current with emerging threats, vulnerabilities, and cybersecurity technologies.
• Proactively identify areas for risk reduction and security automation.
• Collaborate across teams to build a culture of security-first thinking in everything we build and deploy.

You Will Be a Good Candidate If You Have

• Bachelor’s degree in Cybersecurity, Computer Science, Information Security, or a related field.
• 3 to 5 years of experience in cybersecurity roles with a focus on application or cloud environments.
• Strong understanding of secure coding, web security standards (e.g., OWASP Top 10), and CI/CD security practices.
• Hands-on experience with CI/CD security.
• Programming or scripting experience in Python or a general-purpose language such as Java, Kotlin, Go, or Ruby is preferred.
• Familiarity with AWS security services, IAM policies, and network security configurations.
• Strong understanding of IAM, SSO/SAML, and API security.
• Experience with vulnerability scanners, container security, and code analysis tools (e.g., Snyk, Trivy, Semgrep).
• Exposure to infrastructure-as-code (e.g., Terraform, CloudFormation) and cloud-native security tools like AWS Config, GuardDuty, and Security Hub.
• Experience with WAFs, penetration testing, and vulnerability management tools.
• Hands-on exposure to SIEM, IDS/IPS, incident response, and cloud-native threat detection.
• Experience with MDM, SSO/SAML, and endpoint protection tools.
• Awareness of compliance frameworks such as ISO 27001, SOC 2, and PDPA.
• Relevant certifications such as CompTIA Security+, AWS Certified Security, or equivalent.
• Ability to clearly communicate security risks and remediation paths to engineering and platform teams.

Culture And Benefits

• Get involved in product development from the ground up to chart the future of Flo.
• Work in an open-minded and dynamic environment with a talented team.
