Superhuman is building the AI-native future of work: a family of products people and companies rely on to think, write, and get things done faster. We ship AI features and agents at a pace that makes security one of the most interesting problems in the building, and we're looking for a Platform Security Engineer to help us solve it. Your job won't be to slow us down; it will be to make moving fast the safe default. You will be building the identity model, guardrails, and secure-by-default platform that lets our engineers and AI systems operate boldly. You'll work on bleeding-edge AI, data, and platform security problems: securing AI agents and the infrastructure behind them, taming identity sprawl across a multi-product cloud, and hardening the supply chain that ships it all.

As a Platform Security Engineer at Superhuman, you will:

• Design and implement secure-by-default infrastructure that makes the secure path the easiest path for developers across Superhuman's product ecosystem.

• Pioneer the use of AI and automation to scale security capabilities, from building tooling in collaboration with our SRE and Release Engineering teams to automating vulnerability remediation.

• Partner with Platform, Release Engineering, SRE, Data Engineering, and Product Engineering teams to define and drive secure-by-default environments supporting product needs.

• Build bridges between technical and non-technical teams by translating security requirements into actionable roadmaps aligned with business objectives.

• Balance security excellence with product innovation, making risk-informed decisions that safeguard customer data while enabling Superhuman to move fast.

• Stand with the Security Team at the forefront of AI security, where you'll help define the playbook for protecting AI-powered systems and tackle novel security challenges.

• Has 5+ years of experience securing cloud infrastructure at scale in AWS, GCP, or Azure.

• Hands-on cloud security depth, designing and building (not just auditing) secure cloud architecture.

• Infrastructure as code fluency, Terraform or equivalent, building reusable, secure-by-default modules and policy-as-code.

• Experience with software supply chain and CI/CD infrastructure security, containerization (Docker, K8s), and an understanding of the associated risks.

• Understanding of zero-trust and IAM principles for both human and non-human identities.

• An interest in using AI to solve Security challenges at scale.

• Familiarity with software engineering or scripting in languages like Python, Java, or Go.

• The ability to think like an adversary to identify risk, and then build like an engineer to mitigate those risks.

• Has a demonstrated ability to work independently with minimal guidance, proactively manages tasks and priorities across multiple projects, analyzes and executes work efficiently, collaborates effectively with cross-functional teams, and thrives in fast-paced, results-driven environments.
