Transparency is key for us. Luno stores all crypto on a 1:1 basis and we have rigorous processes in place so you can be confident your investment is secure. We’re available in more than 40 countries around the world and we work closely with respective regulators in all of these markets to be fully compliant, as we believe this is the best way to help everyone, everywhere, invest safely.
About the team:
The Cloud Security team at Luno is responsible for identifying security threats and improvement areas within our cloud hosted resources, and ensuring that we both strive to implement best practices everywhere and detect any deviations. This team works closely with engineering and IT operations to ensure the best security practices are followed in both areas of the business.
About the role:
We're looking for a Senior AWS Cloud Security Specialist to be a force multiplier across the organisation, someone who brings deep cloud security expertise, strong architectural thinking, and the confidence to challenge assumptions when needed.
You’ll work hands-on across our AWS, Kubernetes, CI/CD and developer environments, surfacing risks early, designing secure patterns, automating controls, and strengthening the foundational security posture that underpins a global crypto exchange.
This is a role for someone who wants to build, influence, advise, and elevate — not just run scanners.
Your mission will be:
- Continuously assess and uplift the security posture of our AWS and Kubernetes environments through automation and secure-by-design principles.
- Partner closely with Engineering, SRE, and IT Ops to deliver practical, business-enabling security solutions — not blockers.
- Analyse existing infrastructure and microservice architectures, highlight systemic risks, and define secure patterns that scale.
- Lead security input across new projects from design → delivery, ensuring resilient architectures and guardrails are in place early.
- Develop proof-of-concepts, hardening strategies, and safe rollout plans for improvements.
- Strengthen detection and response capabilities by improving security telemetry, triage, anomaly detection, and automation
A little about you:
- Advanced AWS expertise — ideally with Professional or Specialty certifications.
- Strong experience in Kubernetes, cluster security, and containerised workloads.
- Background in Cloud Engineering / SRE / DevOps / Systems with strong security instincts.
- Proficiency in automation and scripting (Python preferred).
- Hands-on experience with Terraform and secure IaC patterns.
- A solid understanding of CI/CD pipelines and the SDLC.
- A mindset that balances pragmatic engineering with strong security judgement.
- Curiosity, ownership, and a genuine passion for learning and improving systems
