• Be a foundational architect and builder in the quest for a resilient, decentralized and unbiased world currency. • Tackle fundamental challenges in how software mediates thought, how AI augments human capability, and how complex information can be made intuitively navigable and creatively extensible. • Focus on building automated workflows and data systems that serve as critical infrastructure and early explorations into these deeper challenges of structure, change, and representation. • Lead the design and implementation of the “Atlas Workflow Automation v2” system, focusing on robust data synchronization between Notion and our backend, precise change-tracking for hierarchical content, and automated governance proposal generation. • Develop and own the reliability of data pipelines, including implementing automated testing, comprehensive monitoring, and robust rollback/repair tooling. • Architect and build core backend services and data models with an emphasis on event-driven architecture.
Job Requirements
- 5+ yrs building production back-end / server-side systems, with strong proficiency in JavaScript/TypeScript (Node.js) AND demonstrated experience with at least one of Python, Go, or Rust/Java.
- Expert-level SQL proficiency and deep experience designing and working with relational databases to manage complex, hierarchical data structures.
- Proven ability to model parent-child relationships, ensure data integrity, and write sophisticated queries for data retrieval, transformation, and change tracking.
- Significant hands-on experience with PostgreSQL is a must.
- Extensive experience with complex third-party REST APIs, including demonstrable, in-depth experience with at least one major content or productivity platform API (e.g., Notion, Google Workspace, Airtable).
- Proficiency with, or ability to quickly ramp up on, Notion API production.
- Proficiency with, or ability to quick ramp up on, design and implementation of diffing algorithms or robust change-tracking logic for structured/hierarchical data.
- Solid grasp of API design principles (REST/GraphQL), secure authentication patterns, and secret management.
- Experience with event-driven architecture, containerization (Docker), modern CI/CD practices, and pipeline observability (automated tests, monitoring).
- Deep into AI-assisted coding and eager to test/taste all the new models and tools
- Experience with Model Context Protocol (MCP) servers.
- Experience with PostgreSQL-based Backend-as-a-Service (BaaS) platforms (like Supabase) or building custom backend services on PostgreSQL that expose data via APIs is a strong plus, particularly if you’ve leveraged platform-specific features (e.g., advanced functions, RLS) for automation, security, or data synchronization in such an environment.
- Experience or strong interest in designing extensible platforms, frameworks, or systems with rich plugin architectures or APIs for customization.
- Excellent technical communication and a collaborative, first-principles thinking approach.
- Resourceful, self-directed, and comfortable navigating the ambiguity inherent in exploring new frontiers.
