Full Stack Developer (Backend)

REVENUEBASE: - We're building the data infrastructure that makes AI agents trustworthy instead of error-prone. - We provide continuously refreshed, verified B2B data for autonomous AI agents and GTM workflows. - We've tripled growth while maintaining 100% gross dollar retention and staying cashflow positive. - We power AI agents for Clay, Orbital, Dun & Bradstreet, and the next generation of AI GTM tools. WHY WE'RE HIRING THIS ROLE: - Our product and platform are scaling rapidly, and we need experienced backend engineers who can ship reliably, own services end-to-end, and maintain high performance as our data infrastructure grows. - This role exists to strengthen our backend systems, APIs, and cloud infrastructure — ensuring our platform remains fast, scalable, and dependable under increasing data volume and customer demand. - You’ll work on systems that customers rely on in production — where backend performance, data integrity, and reliability directly impact retention and growth. WHAT YOU'LL DO - Design, build, and maintain scalable backend services using Python and FastAPI. - Develop and optimize high-performance RESTful APIs powering AI agents and GTM workflows. - Architect and maintain cloud-native infrastructure (compute, storage, networking). - Build reliable data pipelines and services that process, validate, and serve large B2B datasets. - Ensure system scalability, observability, and fault tolerance. - Own backend features end-to-end — from design and implementation to deployment and monitoring. - Collaborate closely with frontend and data engineers to ensure clean API contracts and reliable data flow. - Contribute to architectural decisions, code reviews, and engineering best practices. - Continuously improve performance, security, and maintainability across backend systems. WHO YOU ARE - 4+ years of professional backend development experience. - Strong proficiency in Python. - Hands-on experience with: - FastAPI - RESTful API design and implementation - Relational databases (PostgreSQL or similar) and NoSQL Databases (DynamoDB or similar) - Asynchronous programming - Cloud platforms (AWS, GCP, or Azure) - Experience with containerization and deployment (Docker). - Solid understanding of distributed systems concepts (caching, queues, background jobs). - Comfortable designing scalable systems and optimizing for performance. - Familiar with authentication, authorization, and API security best practices. - Experience working in a fast-moving, remote-first environment. - You take ownership, communicate clearly, and ship production-quality systems. - You care about performance, reliability, and long-term maintainability. WHY REVENUEBASE: - Product with real traction: Customers rely on our platform in production. - High ownership: Small team where your work directly shapes the product. - Engineering-driven culture: Quality and correctness matter. - Growth stage company: Clear product-market fit and momentum. - Impact over process: Less bureaucracy, more building. WHAT WE OFFER: - Competitive compensation based on experience. - Meaningful ownership and long-term growth opportunities. - Flexible working hours. - Fully remote-friendly team. - Direct collaboration with founders and core engineering leadership.
