About the role

Senior Software Engineer - Full Stack at Cinder, focusing on building scalable infrastructure for content review, AI agents, workflow orchestration, and integrations for Trust & Safety at scale.

Responsibilities

  • AI agents that review content against customer policies, callable from within our durable workflow engine.
  • A workflow engine built on Restate for durable execution. Engineers build new nodes that customers wire together to automate moderation pipelines, NCMEC reporting, enforcement actions, and more.
  • Review queue tooling: the core UI where moderators and investigators spend their day. Features like QA decision overrides, attribute-level labeling, forms, and skills-based routing.
  • Analytics and metrics dashboards for T&S leads, built with a React frontend backed by a Django/GraphQL API.
  • Two-way user communications: building integrations (Salesforce, Zendesk) so moderators can contact users and see conversation history without leaving Cinder.
  • Reliability at scale: define SLIs, improve pipeline throughput, and own oncall for systems where downtime affects moderation workflows.

Qualifications

  • 5+ years building production software, with experience across the stack: Django or similar backend frameworks, React or similar frontend, relational databases, and message/event systems.
  • Experience identifying customer problems and delivering end-to-end solutions; participation in customer demos and shaping product direction.
  • Experience with high-throughput, data-intensive systems ingesting large volumes of entity data, events, and media; ability to reason about throughput and latency at scale.
  • Strong stance on how AI tooling changes the way code is written; fluency and opinionated use of AI in development.
  • End-to-end ownership: understanding data model, API, and UI to deliver usable features from start to finish.
  • Clear written communication, with experience in PRs, Slack, and customer-facing documentation.
