Software Engineer, Trust & Safety

5+ years of software engineering experience Fluent in writing and speaking English Deep experience with Node.js, TypeScript, 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 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

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
