Sure our solutions sound complex but our mission is simple: make receipts easy for everyone.

The Role

You are the Technical Architect and Force Multiplier for our Backend chapter. While you will still write code (especially on the critical path) your primary focus is Architecture and Leverage. You will look across multiple squads to identify patterns remove bottlenecks and design the distributed systems that underpin our entire platform.

You will also be a pioneer in our AI-Enabled strategy. You wont just use Copilot; you will define the patterns and workflows for how our 50 engineers leverage AI to build better software faster.
