Each squad has ownership of parts of our platform, and you'll collaborate closely with product managers, frontend engineers, and other backend specialists to deliver end-to-end solutions.

We're looking for someone who thrives on accountability, loves solving complex technical problems, and brings genuine craft to their engineering.

• Collaborate within your squad (Product, Frontend, Backend, Design) to deliver complete solutions with real customer impact
• Mentor and guide junior engineers, raising the bar for backend craftsmanship
• Explore and introduce new frameworks, tools, and approaches that bring value to the team
