Responsibilities
You’ll join the Billing Engineering team, responsible for building and evolving the systems that power how our customers are billed for their usage across AI workloads
This isn’t a space with established playbooks — we’re designing billing systems that fit a new generation of AI products, where no one has fully figured out what 'right' looks like yet
As a Full Stack Engineer on the Billing team, you’ll help create the systems that determine how our customers understand, control, and pay for their usage — a space where thoughtful engineering directly shapes user trust and business value
You’ll design and build end-to-end features across Go and React, collaborating closely with teammates to refine what success looks like as we learn

Comfortable building and connecting systems through APIs, and curious about how those connections shape the product experience
Experience thinking about performance and stability in real-world systems — for example, optimizing queries, caching data, or handling edge cases gracefully
Bonus: you've built something end-to-end that people actually use — even if it's just for fun or for yourself
Preferred
Interested in how user incentives and perceptions of value are driven by pricing and product design
Passionate about understanding how thoughtful software design can drive flexibility, empower better user experiences, and enable the business to adapt to evolving needs
Energized by exploring open problems and helping shape what success looks like alongside your team
