## Job description

Resend is growing fast, and there are now over 4 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. [Read more about how we work, how we hire, and what we value here](https://resend.com/handbook).

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
- Comp: $140,000 - $160,000 USD, commensurate with experience

- **Entity Type**: Private (Series A)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2023
- **Founders**: Zeno Rocha (CEO), Bu Kinoshita (CTO), Jonni Lundy

## Core Business
- Primary industry: Developer tools / Email infrastructure (Communication API)
- Target customers: B2B, primarily developers and engineering teams at startups, SMBs, and enterprises
- Mission statement: Reimagine email for the modern web — building the best communication platform for developers

## Products & Services
- **Email API**: A RESTful API for sending transactional and marketing emails at scale, with SDKs for Node.js, Python, PHP, Ruby, Go, Java, Laravel, Rust, and .NET.
- **React Email (open source)**: A library (5.1k+ GitHub stars) that lets developers code email templates using React components instead of outdated HTML layouts.
- **Resend CLI**: Command-line tool for sending emails directly from the terminal.
- **Deliverability Engine**: Infrastructure focused on inbox placement and avoiding spam folders, backed by SOC 2 compliance and GDPR adherence.

## Market Standing
- **Valuation/Total Funding**: $18M Series A (announced December 4, 2024)
- **Key Metric**: Total funding raised — $18M Series A
- **Notable Investors/Partners**: Y Combinator (Winter 2023 batch), with backing from "incredible investors" including Diana Hu (YC primary partner)
- **Growth Signals**: Launched in 2023, grew to 45 team members as of mid-2025; Y Combinator backing; open source community traction (React Email); challenger brand in a market dominated by SendGrid, AWS SES, and Postmark

## Competitive Advantages
- **Developer-first experience**: React-based email components, modern API design, and extensive SDK support set them apart from legacy providers.
- **Open source community**: React Email has strong adoption (5.1k+ stars) and creates a natural pipeline to the paid API.
- **Deliverability focus**: Deep investment in inbox placement technology, a known pain point for developers.
- **Challenger mindset**: Actively rethinking email infrastructure from scratch, not just copying incumbents.

## Strategic Focus
- **Default to action**: Company culture emphasizes shipping fast, iterating quickly, and taking initiative without permission.
- **Remote-first**: Fully remote company with async communication, two annual offsites, and timezone overlap within the Americas.
- **Quality obsession**: Focus on craft, attention to detail, and delighting developers — challenging the "good enough" status quo in email.
- **Growth stage**: Post-Series A, actively hiring across engineering (Backend, Security, Product, Deliverability) to scale the platform.

## Why Work Here
- **Remote-first culture**: Fully remote with async communication, no plans for mandatory offices. Two annual in-person retreats.
- **Engineering philosophy**: "Default to action" — makers ship PRs, not wait for permission. Emphasis on speed, iteration, and quality.
- **Benefits (Global)**: 20 PTO days/year, 12-week family leave, unlimited sick days, 10 holidays/year (choose US or local), $2,000 home office allowance, annual retreat.
- **Benefits (US-only)**: 100% employee / 90% family health/dental/vision coverage, 401K account (no matching), life insurance.
- **Team size**: ~45 people (as of mid-2025) — early-stage energy with significant traction.
- **Culture values**: No ego, confident curiosity, challenge the status quo, use resources available — documented in a public handbook.
