Software Engineer, Trust & Safety

Email is unlike any other medium in the world. With just an address,
anyone can talk to anyone
, no matter their location, status, or class. Its democratized access, its a sacred privilege, and its worth protecting at all costs.

Resend is building the most accessible email platform for developers. As weve grown to over 15K customers and continue to onboard thousands of new users every day, the pressure of maintaining a safe place for good senders continues to build up.

Youll build the interfaces, services, tooling, and enforcement pipelines for Trust & Safety. From consoles to enforcement automations.

In this role, you will

• Build and maintain internal services for enforcement, throttling, and policy rules

• Design automation pipelines that move from detection ? decision ? action

• Connect with core infrastructure: databases, queues, caching layers, and observability stacks

• Implement safeguards: fail-safes, fallback paths, and guardrails to prevent over-blocking

• Collaborate with teams to turn raw signals into actionable workflows

• Ensure all enforcement actions are traceable with logs, metrics, and audit trails

Youll be a great fit if you

• Bring 5+ years of software engineering experience

• Are fluent in writing and speaking English

• Have deep experience with Node.js, Type Script, React (Express, Hono, Next.js)

• Proven experience with databases and performance tuning (Postgres, Clickhouse)

• Infrastructure and reliability skills (Datadog, AWS, CDK)

• Understand how to design systems with safety and fail-safe operations in mind

• Are comfortable with APIs, event-driven architectures, and stateful services

• Care deeply about observability: metrics, logs, tracing, error handling

• Take ownership across the stack from frontend surfaces down to databases and queues

• Have worked in trust, safety, fraud, or security domains

• Have exposure to real-time enforcement systems, such as rate-limiting
