Develop and maintain anti-abuse systems to ensure secure email delivery and prevent abuse.
О компании
- We are building the modern email sending platform for developers. We care deeply about quality, craft, and the developer experience.
- Our fully remote team of 50 spans 15 countries and counting. We're backed by a16z, Y Combinator, and others. Meet the humans →
Обязанности
- 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
Требования
- 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)

- 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 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.
- 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
- Our philosophy for anti-abuse
- $3M to make email safer
- Revoking leaked API keys with GitHub secret scanning
