Tokenization Jobs in Florida (NOW HIRING)

Job Summary:
PayCargo is the world's leading online payment solution that is revolutionizing the shipping and cargo world. The Senior Engineer, Cloud Security is responsible for strengthening and operating security controls across a modernizing platform, focusing on implementing and operating security controls while partnering with various teams to ensure the security and availability of PayCargo's global payments platform.
Responsibilities:
• Monitor the perimeter, cloud, and endpoint environments for threats, misconfigurations, and anomalous activity across AWS and Microsoft Entra ID
• Operate and tune security tooling, including CrowdStrike, Microsoft Defender, and CloudWatch and SNS logging and alerting
• Triage security alerts, drive incident response, and lead root cause analysis with clear, durable follow-up
• Maintain and improve on-call and escalation workflows (e.g., PagerDuty) so security events are handled consistently
• Run periodic access reviews and enforce least privilege across AWS IAM and IAM Identity Center, Microsoft Entra ID, and SaaS platforms
• Strengthen RBAC/ABAC, MFA, and SSO, SAML2, and OAuth2/OIDC patterns across internal and customer-facing systems
• Reduce standing access and broad repository or local admin privileges in favor of bounded, auditable access
• Operate the federated access model, including SAML-based assumed access to AWS (via CommonFate Granted) and GitHub OIDC for pipelines, so people and CI receive least-privilege, time-bound access without static credentials
• Operate the PKI, including AWS Private CA and ACM, certificate issuance and rotation, CRLs, and mTLS trust stores on load balancers
• Administer Entra ID groups and the Tailscale ACLs that gate network access
• Govern dependency and supply-chain risk using Dependabot and approved-package practices, and keep secrets in AWS Secrets Manager and SSM Parameter Store
• Support SOC 1 Type 2, SOC 2, and PCI DSS obligations by owning the implementation of controls and the evidence behind them
• Coordinate penetration testing, remediation tracking, and verification of fixes
• Produce clean, repeatable audit evidence and reduce last-minute audit scrambles
• Translate compliance requirements into operational controls engineers can follow without constant guidance
• Help enforce containment for AI and model usage, including stateless model access, whitelisted egress, and approved destinations
• Support tokenization and PII-protection patterns so sensitive data is not exposed to model providers
• Review AI-assisted workflows and applications for security boundaries, logging, and blast-radius reduction
• Partner with DevOps and Engineering to embed security into the Terraform and GitHub Actions pipelines, environments, and deployment paths
• Work with Compliance on audits and frameworks (SOC, PCI, ISO 27001) and on auditor-facing reporting
• Advise Product and Architecture on secure-by-design patterns and practical trade-offs
• Implement and operate the security controls, boundaries, and egress rules defined in the platform architecture owned by the Director of Cloud & AI Platform Architecture
• Provide clear status, escalate risks early, and document controls, runbooks, and decisions
Qualifications:
Required:
• 5+ years of hands-on security engineering, cloud security, or security operations experience preferred
• Strong working knowledge of AWS security and identity services, plus an enterprise identity provider such as Microsoft Entra ID or Okta
• Hands-on experience with endpoint and threat tooling such as CrowdStrike and Microsoft Defender
• Practical experience with SOC and/or PCI DSS controls, audits, and evidence
• Strong understanding of IAM, RBAC/ABAC, MFA, SSO, SAML2, OAuth2/OIDC, JWT, including common failure modes, and least-privilege design
• Hands-on experience with PKI and certificates, including a certificate authority such as AWS Private CA, TLS and mTLS, and certificate issuance, rotation, and revocation
• Experience with incident response, logging and alerting, and root cause analysis
• Ability to convert security and compliance requirements into repeatable operational controls
• Strong communication and documentation skills, and the ability to influence without direct authority
• Bachelor's degree in Computer Science, Information Technology, Cybersecurity, Engineering, or a related field, or equivalent practical experience
• 5+ years of hands-on security engineering, cloud security, or security operations experience preferred
• Demonstrated experience operating production security controls in cloud environments
• Experience supporting SOC, PCI, or comparable audits and frameworks
• Payments, fintech, SaaS, or logistics experience is a plus
Preferred:
• Security certifications such as CISSP, CISM, CCSP, or equivalent
• Experience coordinating penetration testing and managing remediation
• Familiarity with secure AI/LLM patterns, data tokenization, and egress control
• Experience securing CI/CD pipelines (GitHub Actions), GitHub/ZenHub, and Terraform-based infrastructure-as-code
• Experience with zero-trust network access such as Tailscale or Zscaler, and SSO brokers such as CommonFate Granted
• Experience in payments, fintech, SaaS, or other regulated, high-volume environments
• Familiarity with ISO 27001 and SaaS security posture management
