Base0 is solving the problem of fragmented context in modern AI workflows, where project knowledge is scattered across various tools and conversations, leading to inefficiencies and reduced productivity. The company aims to bring context, continuity, and observability to AI-powered work.

Requirements

  • Strong Python fundamentals and experience with modern web frameworks.
  • Deep understanding of data modeling and SQL with hands-on experience in relational databases.
  • Experience designing distributed and asynchronous systems for scale and reliability.
  • Understanding of vector or graph data models and their role in search, retrieval, or knowledge systems.
  • Solid foundation in cloud-native operations — containerization, orchestration, monitoring, and scaling.
  • Strong debugging, observability, and incident-management skills.
  • Awareness of security best practices, PII handling, and compliance principles.

Responsibilities

  • Design, Build, & Maintain APIs: Build reliable, versioned interfaces that power Base0’s product and external integrations.
  • Architect Data Systems: Design and optimize relational, vector, and graph-based data stores that represent interconnected project context.
  • Build Distributed Services: Develop and scale backend systems using modern Python frameworks and asynchronous processing patterns.
  • Integrate AI Workflows: Combine retrieval and generation pipelines to deliver context-rich, adaptive intelligence within the platform.
  • Ensure Reliability & Security: Design for fault tolerance, enforce access control, manage secrets securely, and maintain compliance with data protection standards.
  • Operate in Production: Deploy, monitor, and optimize services with meaningful metrics, alerts, and incident response practices.
  • Debug & Optimize: Trace issues end-to-end, fix root causes, and continuously improve system performance and resilience.

Other

  • 5+ years building and operating backend or full-stack systems in production environments.
  • Track record of owning systems end-to-end — from design to post-launch operation.
  • Clear, proactive communicator comfortable working with product and research partners.
  • Thrive on autonomy, clarity, and collaboration.
