About the job
Duna is looking for a Senior Infrastructure & Security Engineer to own and harden their cloud and security systems. This remote role combines deep infrastructure work with security engineering, from AWS and Kubernetes to SOC 2 automation and AI safety.
What you will do
- Own and harden AWS, Kubernetes, Postgres, infrastructure as code, CI/CD, observability, and incident response
- Make security the default with least privilege, secrets management, and tenant isolation
- Automate SOC 2 and ISO 27001 controls and evidence
- Turn operational toil into self-service systems like preview environments and internal access
- Help run AI agents safely with sandboxes, guardrails, and human checkpoints
- Take calm ownership of incidents and improve the system afterwards
What you bring
- Deep hands-on experience with AWS, Kubernetes, infrastructure as code, CI/CD, and observability
- Real security engineering skills to turn least privilege and auditability into working systems
- Comfort with enterprise IT side of a startup including certifications, customer security reviews, identity, and device management
- High agency in ambiguity, turning vague problems into shipped plans
- Pragmatic judgement about when to harden, simplify, or leave something alone
- Curiosity about what AI changes in building and running software
