About Cloud and Security team:

Our security team protects user data and keeps the airSlate platform stable.

• Help teams build secure products from the start by joining architecture reviews, threat modeling sessions, and risk assessments
• Explain security findings clearly and work with engineers until the issues are fixed
• Handle security incidents of different kinds (application, infrastructure, user-related): investigate, triage, contain, and write post-mortems
• Prepare for SOC 2 and CASA audits and external assessments together with product and compliance teams
• Configure and monitor our CDN
• Work alongside a small, experienced, and proactive team that solves complex problems together

What we expect from you:

• 4+ years of professional experience in information security, application security, or a related field
• Hands-on experience securing AWS and/or GCP
• Practical experience with SAST, DAST, and SCA tools, including choosing, setting up, and integrating them into CI/CD
• Experience in security testing of web, mobile, or network applications
• Experience in incident response, from investigation to post-mortem
• Good knowledge of secure development practices across the SDLC, including threat modeling
• Working knowledge of Bash, Python, Go, or Terraform
• Clear communication skills and the ability to explain risks so that teams act on them
• English at B2 level or higher, written and spoken

What helps you rock:

• Experience preparing for compliance audits such as SOC 2, CASA, PCI DSS, or NIST CSF
• Previous experience as a DevOps engineer or developer
