Responsibilities

• Design and implement backend services using Python or Node.js
• Work with PostgreSQL (or similar relational databases) to structure and query data
• Build and maintain data pipelines, including tools like Kafka (or similar message / event systems)
• Collaborate with AI engineers to support AI‑driven features and prompt‑engineering pipelines
• Ensure scalability, reliability, and performance across the backend
• Partner closely with frontend developers to deliver fast, efficient APIs

Required Skills

• Proficiency in Python or Node.js
• Strong experience with PostgreSQL or similar databases
• Hands‑on experience with Kafka or similar event streaming tools
• Comfort working with data‑heavy systems and structured / unstructured data
• Experience building production APIs and backend systems
• Ability to work in a greenfield environment with high autonomy

Nice to Have
