About the Role

We are looking for a Principal Backend Engineer to strengthen our calculation engine – a core part of our product responsible for handling complex data imports and modular computations. Your mission will be to optimize the performance of a graph traversal system that enables fast computation of dependencies across hundreds of millions of cells. This role focuses on executing CPU‑bound operations efficiently and scaling the system to support high volumes of concurrent user requests. You’ll work on optimizing large‑scale performance for both sparse and dense data structures, automating processes, and leading initiatives to improve efficiency and manage complexity.

In this role, you’ll have the opportunity to reshape how people approach numerical thinking and analysis. Our innovative tool empowers users to perform calculations, visualize data, and share insights with ease. By combining the flexibility of spreadsheets with the power of programming, we’re making data analysis fast, collaborative, and accessible. You’ll work with modern technologies like the latest versions of Go, TypeScript, PostgreSQL, Redis, and more to collaboratively design and evolve the backend of our award‑winning product.

• Strong understanding of algorithms: Solid grasp of algorithms and data structures, particularly graph algorithms.
• Versatile coding skills: Write clean, maintainable, and performant code while moving quickly and creatively when the situation calls for it.
