This role will focus on backend systems, database design, and API orchestration, with a strong emphasis on data synchronization and workflow automation.
You will be working with technologies like Notion, Supabase, Node.js, and various third-party APIs to automate and improve how data is structured, accessed, and maintained across platforms.
You’ll also contribute to the development of a custom knowledge management tool that goes beyond the limitations of Notion, enabling complex data queries and improved interoperability with AI assistants and future systems.

Collaborate with cross-functional teams to define system architecture and ensure technical alignment.
Research and contribute to building a custom knowledge management platform (e.g., using Model C Protocol Servers).
Advocate for and implement AI-assisted tooling within the workflow.
5+ years of experience building production-level backend services.
Strong proficiency in JavaScript / TypeScript.
Experience with Python, Go, Rust, or Java is a plus.
Solid knowledge of SQL databases, with ability to design and query relational and graph-based schemas.
Experience working with Notion APIs (Node.js) and orchestrating third-party APIs.
Familiarity with pagination, rate limits, and structured data formats.
Ability to design and implement efficient algorithms.
Experience with Supabase or equivalent modern DB platforms.
