Job description

We’re building a brand-new SaaS platform from scratch—no legacy code, full ownership, and the opportunity to shape the architecture from day one. The product is a marketing analytics and reporting system that helps users surface insights across their entire funnel.

A core aspect of this platform will be an AI agent that monitors all marketing data and generates clear, actionable insights. Your backend systems will power this intelligence layer.

• ETL/data pipelines for marketing funnel analytics
• Integrations with AI/LLM services and data-processing workflows
• APIs that support dashboards, reports, and automated insight generation
• Real-time or near–real-time data ingestion using event-driven tools

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

• Experience with AI/LLM tools or prompt engineering
• Background building analytics dashboards or marketing data systems
• Experience developing AI agents that operate on data streams

• Unlimited Paid Time Off (PTO): We believe in work-life balance and trust our team to manage their time responsibly

• Collaborative Team: Join a tight-knit team where your ideas and leadership will directly shape client outcomes
