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.

This role sits at the intersection of:

• Frontend engineering
• Developer experience
• 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
• Drive AI-native development workflows across our frontend and developer tooling

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

• Design and maintain JavaScript/TypeScript SDKs used by partners integrating Benji
• Build reusable UI components and integration patterns for loyalty experiences
• Ensure SDKs are intuitive, well-documented, and easy to adopt
• Own versioning, backward compatibility, and developer ergonomics

2. Own Frontend Architecture (Vue3 + TypeScript)

• Build and scale applications using Vue 3 + TypeScript
• Define frontend architecture, state management, and performance patterns
• Collaborate closely with backend and product teams on API design and integration flows
• Optimize for reliability, performance, and maintainability

3. Shape the Developer Experience

• Build and improve:
  • Developer portal interfaces
  • Integration flows and onboarding UX
  • Interactive documentation and examples
• Create tools that make it easier for developers to understand, test, and implement integrations

4. Build AI-Native Frontend Workflows

• Integrate AI deeply into the frontend development lifecycle:
  • AI-assisted SDK usage and integration flows
  • Developer copilots embedded in the UI
  • Smart debugging and error resolution experiences
• Build and leverage LLM-powered tools, agents, and MCPs to enhance developer productivity
• Use AI to generate UI scaffolding, integration examples, and dynamic documentation

Who You Are

• 5+ years of experience as a frontend or full-stack engineer
• Strong expertise in Vue 3 and TypeScript
• Experience building developer-facing products, SDKs, or frontend platforms
• Deep understanding of API integration patterns (REST, auth, webhooks)
• Strong product instincts—you care about usability and developer experience

Required

• Hands-on experience working with LLMs and AI developer tooling
• Experience building or integrating:
  • AI-powered developer workflows or copilots
  • Agents, MCPs, or similar tooling layers
• Familiarity with prompt design, tool usage, and embedding AI into real product experiences
• Strong interest in using AI to improve frontend development and developer velocity

Nice to Have

• Experience building cross-platform or mobile-friendly experiences
• Backend experience (Python preferred)
• Experience designing or maintaining SDKs used by external developers
• Familiarity with API platforms (Stripe, Plaid, Twilio, etc.)
• Experience with design systems or component libraries

What Makes This Role Unique

• You’ll define how developers interact with Benji on the frontend
• You’ll build SDKs and tools used by real enterprise partners
• You’ll operate at the intersection of frontend, developer experience, and AI
• You’ll help pioneer AI-native frontend development workflows

Compensation & Benefits

• Competitive salary + equity
• Health, dental, vision
• Flexible work environment

Why Benji

We’re building something ambitious: the infrastructure layer for loyalty ecosystems. If you enjoy building elegant frontend systems, crafting exceptional developer experiences, and pushing the boundaries of AI-driven development—this role is for you.
