Resend is growing fast, and there are now over 4 million developers using it. We’re building tools that make email better for developers. We care about dependable infrastructure, thoughtful design, and the experience of everyone building with our products.
In this role you'll build the anti-abuse systems that keep Resend open for good senders and closed to bad actors: real-time enforcement on every email, detection pipelines that scale with the platform, and automations that go from detection to action without waiting on a human.
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.
Build and run the real-time enforcement layer within a latency budget of milliseconds
Design pipelines that move from signal to decision to action, across sending, receiving and account activity
Build the detection rules and policies that decide when we act, and make them safe to change
Detect and contain account takeover and leaked API keys: notice when a trusted account stops acting like itself, and stop the damage without locking out the real owner
Close the feedback loop: every block and every reversal carries a reason, so we can measure each detection's precision and retire the ones that hurt good senders
Automate manual work such as investigations, appeals and bulk actions, so the team keeps up as volume grows
Build and evaluate ML classifiers for spam and phishing, and prove their precision before they enforce anything
Implement safeguards and make every action traceable through logs, metrics and audit trails
Ensure all enforcement actions are traceable with logs, metrics, and audit trails
Bring 5+ years of software engineering experience
Are fluent in writing and speaking English
Have deep experience with Node.js, TypeScript, React (Hono, Next.js)
Write Go, or want to, for latency-sensitive services
Have infrastructure and reliability skills (AWS, CDK, Datadog)
Are comfortable with APIs, event-driven architectures, queues and stateful services
Design systems that fail safe, and treat a false positive as a bug
Care deeply about observability: metrics, logs, tracing, error handling
Take ownership across the stack, from frontend surfaces down to databases and queues
Have proven experience with databases (Postgres, Redis)
Have worked in trust and safety, fraud or security
Have built real-time enforcement such as rate limiting, or a rules engine on a policy language like CEL
Have shipped ML or LLM-based detection in production, and know how to measure its precision and recall
Know email: SPF, DKIM, DMARC, bounces, complaints, and how phishing campaigns work
Have knowledge of database performance tuning (Postgres, Redis)
Room to shape technical decisions and take projects from discovery through production
Work remotely with teammates around the world
Close collaboration with the developers who use what you build
Teammates who value thoughtful feedback, shared learning, and care for each other
A high bar for product quality, reliability, and the details that make software enjoyable to use
Comp: $150,000 - $175,000 USD, commensurate with location and experience
