Security Engineer, Platform

In this role, you will…

• 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
• Have built security observability, alerting, detection pipelines, or incident response workflows
• Have worked closely with Trust & Safety, anti-abuse, fraud, or platform integrity teams
• Have experience designing security systems for high-scale developer products

What it means to join the team:

• Autonomy to "just ship it"
• 100% remote team with flexible working schedules
• Modern tech stack (Next.js, Raycast, Notion, etc.)
• Honest and low-ego team
• Ownership of problems and solutions
