Résumé du poste

RedStone is seeking an senior cybersecurity leader to protect its AWS and cloud infrastructure, detect threats, perform pentests, and roll out practical OpSec standards across all teams. You will work hands-on with the CTO and collaborate with QA, Infrastructure, and Operations leadership.

The role targets production-critical systems in a fast-growing blockchain environment, emphasizing resilience, secure software delivery, and cutting-edge threat detection.

Qualifications

• 5+ years in cybersecurity, including 3+ years leading security for production-critical systems.
• Strong, hands-on knowledge of AWS security and cloud-service protection: IAM, Organizations and SCPs, VPC design, KMS, CloudTrail, WAF; securing containers (EKS/ECS) and serverless workloads
• Experience securing and operating critical financial infrastructure — a bank, exchange, payments, trading, custody or market-data system — where availability and integrity carry a direct financial cost
• Deep understanding of threat detection: building detections, running a SIEM or XDR platform, threat hunting and leading incident response
• Hands-on penetration-testing experience and fluency with standard pentest and cloud-security tooling; you can show what you would break and how
• A track record of designing and rolling out OpSec standards across a whole company — and getting non-engineers to follow them
• Comfortable writing Terraform, TypeScript scripts and GitHub Actions workflows to build controls yourself; you ship fixes, not tickets

Responsabilités

• AWS and cloud security — account structure and guardrails across the SaaS estate
• Threat detection and response — SIEM, detections, alerting, on-call escalation
• Penetration testing and offensive security — internal pentests and external audits
• Critical-infrastructure resilience — change control, dual control, break-glass, availability/SLOs
• Company-wide OpSec standards — governance across all teams
• Blockchain infrastructure security — keys, signing, multisig, on-chain monitoring
• AI in security operations — AI tooling for detection and triage
• Secure software delivery — branch protection, code-review gates, signed artifacts
