Opttab is an AI visibility and GEO platform helping brands understand, measure, and improve how they appear across ChatGPT, Gemini, Google AI Mode, Claude, Perplexity, and other AI platforms.

We are building a sophisticated B2B SaaS platform that brings together AI visibility analytics, competitive intelligence, content optimization, website and crawler analytics, integrations, and automation.

- Integrate frontend applications with REST APIs and backend services
- Handle complex application states, asynchronous data, loading states, errors, permissions, and edge cases
- Optimize frontend performance, rendering, bundle size, page load speed, and overall application responsiveness
- Ensure the platform works consistently across modern browsers and screen sizes
- Implement robust form validation, authentication flows, authorization, and role-based user experiences
- Create clear and intuitive experiences for complex B2B SaaS workflows
- Write clean, reusable, well-tested, and maintainable code
- Review code and help establish strong frontend engineering practices across the team
- Identify technical debt and proactively improve existing frontend architecture
- Debug and resolve production issues across frontend applications
- Work with analytics and product data to continuously improve user experience

B2B SaaS Experience We are specifically looking for someone who understands how modern B2B SaaS applications work.

You should have experience building products involving areas such as:

- Dashboards and analytics
- Complex tables and data visualization
- Workspaces and organizations
- User roles and permissions
- Subscription plans and feature access
- Onboarding flows
- Integrations




- Settings and account management
- Search, filtering, sorting, and segmentation
- Multi-step workflows
- Notifications and activity states
- Large datasets and asynchronous processing
- Enterprise-level user experiences

Experience developing only corporate websites, landing pages, or agency projects without significant SaaS product experience will not be sufficient for this role.

Nice To Have

- Experience developing analytics, AI, martech, SEO, e-commerce, or data intelligence products
- Experience with Tailwind CSS or modern component-based styling approaches
- Experience with component libraries such as Radix UI, shadcn/ui, Untitled UI, or similar
- Experience with charting and data visualization libraries
- Experience with React Query / TanStack Query or similar data-fetching libraries
- Experience with modern state management solutions
- Experience with Playwright, Cypress, Jest, Vitest, or similar testing frameworks
- Experience with Storybook
- Experience with Sentry or frontend monitoring tools
- Experience with WebSockets or real-time application functionality
- Understanding of SEO and server-side rendering
- Experience working in an early-stage or rapidly growing SaaS company
- Experience contributing to frontend architectural decisions
- Experience mentoring other frontend developers
- Familiarity with AI-assisted software development workflows

What We Are Looking For We are looking for more than someone who can convert Figma screens into React components.

We want an engineer who thinks about the product as a whole.

You should question whether a workflow makes sense, identify edge cases before users discover them, care about loading and error states, understand how components will scale across the application, and actively contribute ideas for making the product better.

You should be equally comfortable building a new feature from scratch and improving an existing codebase.
