• Collaborate with and guide frontend engineers on full-stack development using React and modern web frameworks.
• Integrate with core platform services for identity, metadata, and analytics to ensure seamless interoperability.
• Design and manage multi-cloud infrastructure (primarily AWS, with GCP integrations for ML/data workflows).
• Implement robust CI/CD, testing, and deployment pipelines.
• Implement observability using Datadog, Sentry, and other monitoring tools.
• Use modern AI development tools (e.g., GitHub Copilot, Codex, Claude) to accelerate delivery and improve code quality.
• Partner with product managers and data scientists to evolve contextual AI and embedding models for privacy-safe, high-performance targeting.

• Hands‑on experience cloud-based development, primarily AWS (S3, RDS, SNS/SQS, Lambda); exposure to GCP (Pub/Sub, BigQuery).
• Familiarity with Docker, Kubernetes, and modern CI/CD workflows.
• Comfortable using AI-assisted development tools for productivity, testing, and documentation.
• Excellent communication and cross‑functional collaboration skills across technical and non-technical partners.
• Hybrid role based in NYC, with 4 days a week in‑office.

Nice to Have

• Experience in building and maintaining taxonomy management systems.
• Knowledge of contextual or audience targeting, ad‑tech systems, or recommendation platforms.
• Understanding of privacy-safe advertising, first‑party data frameworks, and data‑compliance standards (GDPR, CCPA).
• Exposure to machine‑learning workflows or AI‑based personalization systems.
• Experience with GraphQL, Elasticsearch.
• Experience with observability stacks (Datadog, Sentry).
