Senior Frontend Engineer

About Benji
Benji is building the infrastructure layer for loyalty and brand connectivity. We enable companies to integrate, launch, and scale loyalty experiences across partners through a single platform—turning fragmented ecosystems into programmable networks. We work with leading enterprise brands and move fast to bring new partnerships and integrations to life.

The role
We’re looking for a Senior Frontend Engineer to own and evolve the developer-facing experience of Benji.

• SDK design
• AI-powered tooling

You will:

Build and maintain our frontend SDKs and developer interfaces
Shape how developers integrate with Benji visually and programmatically

This is not a traditional frontend role—you’ll be building products for developers, not just end users.

What You’ll Do

1. Build Developer-Facing SDKs & UI Components
2. Design and maintain JavaScript/TypeScript SDKs used by partners integrating Benji
3. Build reusable UI components and integration patterns for loyalty experiences
4. Ensure SDKs are intuitive, well-documented, and easy to adopt

5. Own versioning, backward compatibility, and developer ergonomics

6. Build Developer-Facing SDKs & UI Components

7. Build and scale applications using Vue 3 + TypeScript

8. Define frontend architecture, state management, and performance patterns

9. Collaborate closely with backend and product teams on API design and integration flows

10. Optimize for reliability, performance, and maintainability

11. Shape the Developer Experience

12. Build and improve developer portal interfaces, integration flows + onboarding UX, and interactive documentation + examples

13. Create tools that make it easier for developers to understand, test, and implement integrations

14. Build Developer-Facing SDKs & UI Components

15. Integrate AI deeply into the frontend development lifecycle:

16. AI-assisted SDK usage and integration flows

17. Developer copilots embedded in the UI

18. Smart debugging and error resolution experiences

19. Build and leverage LLM-powered tools, agents, and MCPs to enhance developer productivity

20. Use AI to generate UI scaffolding, integration examples, and dynamic documentation

Experience building or integrating:

What makes this role unique
You’ll define how developers interact with Benji on the frontend
