Resend is growing fast, and there are now over 2 million developers using it. As the Platform Squad, we are responsible for the internal platform and reliability foundations that let Resend teams build, deploy, observe, and operate services safely.

This role is fully remote based in Americas or European timezones, with some expected travel for team offsites, conferences, meetups, and more.

Build and improve the security foundations of Resend’s platform, including API keys, service permissions, secrets management, tenant isolation, audit logs, and internal access controls
Help design secure defaults for new services, workers, queues, databases, internal tools, and deployment pipelines
Improve detection and response for suspicious access, leaked credentials, abnormal sending behavior, privilege changes, and sensitive system events
Review and update our processes/pipelines so that security is “built-in”, not “bolt-on”
Raise the security bar

You will be a great fit if you...

Have experience securing production infrastructure, cloud environments, APIs, developer platforms, or multi-tenant SaaS products
Can write code and are comfortable reading application, infrastructure, and deployment code
Understand authentication, authorization, secrets, IAM, logging, audit trails, incident response, and secure deployment pipelines.
Independently prioritize and drive your day-to-day as the first dedicated security hire
Prefer practical improvements over heavy processes
Are low-ego, direct, curious, and willing to learn from others
Care about developer experience and believe security should be easy to adopt

You will be an exceptional fit if you also...

Have experience with email infrastructure, transactional email, sender reputation, domain verification, SPF, DKIM, DMARC, webhooks, or abuse prevention
Have secured cloud infrastructure using tools like AWS, Terraform, Kubernetes, Cloudflare, or similar systems
Have experience with open source security, GitHub organization hardening, package publishing, dependency review, or supply-chain security
Have helped a company prepare for SOC 2, ISO 27001, GDPR, enterprise security reviews, or customer trust processes without turning engineering into a compliance machine
