• Experience working across different parts of the stack, with the ability to build internal tools or frontend interfaces when needed.
• Strong problem-solving skills and an ability to navigate ambiguous requirements and make pragmatic engineering decisions.
• Ability to collaborate effectively with engineers and non-technical stakeholders across different functions.

Bonus skills:

• Experience building Trust & Safety, content moderation, fraud detection, or abuse prevention systems.
• Experience building guardrails or safety infrastructure for AI agents and LLM-based applications.
• Experience deploying and integrating ML models into production applications.
• Familiarity with Kubernetes, Docker, CI/CD pipelines, and cloud infrastructure (AWS/GCP).
• Experience with monitoring and observability tools such as Prometheus and Grafana.
• Experience with React or other modern frontend frameworks.
• Experience with real-time data processing, event-driven architectures, or technologies such as Kafka and Redis.
