What Are We Looking For

We’re looking for a Platform Security Engineer to join our team and help strengthen the security of Supabase’s infrastructure, cloud platform, Kubernetes environments, and containerized workloads as we continue to scale. You’ll work closely with infrastructure, platform, SRE, product engineering, and technical leadership, helping us proactively reduce risk across the systems that run Supabase.

This role is ideal for someone who has deep hands-on experience with AWS, Kubernetes, containers, Linux, and large cloud environments and is excited about securing developer infrastructure without slowing teams down. Success in this role means improving the security posture of the platform through pragmatic engineering, clear technical judgment, and scalable guardrails.

What You’ll Be Responsible for

In this role, you’ll:

• Identify and reduce security risk across AWS, Kubernetes, containerized workloads, and platform infrastructure.
• Conduct threat modeling, architecture reviews, and technical risk assessments for platform and infrastructure systems.
• Partner closely with infrastructure, platform, and SRE teams to design practical controls and secure-by-default patterns.
• Improve Kubernetes and container security across areas like workload isolation, RBAC, admission control, secrets, network policy, and runtime hardening.
• Assess container runtime and Linux isolation risks, including capabilities, seccomp/AppArmor, namespaces, cgroups, and container escape scenarios.
• Strengthen AWS security posture across IAM, account boundaries, network controls, logging, detection, encryption, and service configuration.
• Build scalable mechanisms such as automation, guardrails, paved paths, detection, secure defaults, and review frameworks.
• Distinguish between theoretical risk and material platform risk to prioritize security efforts effectively.

You Might Be a Good Fit If

• You have senior-level experience in platform security, cloud security, infrastructure security, container security, or security engineering.
• You have deep practical experience with AWS, Kubernetes, containers, and Linux security fundamentals.
• You have worked in large cloud environments, multi-cluster Kubernetes setups, developer platforms, SaaS platforms, or high-scale infrastructure teams.
• You can reason clearly about identity, networking,
