B2 B Saa S Experience

We are specifically looking for someone who understands how modern B2 B Saa S 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 Saa S 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 / Tan Stack Query or similar data-fetching libraries

Experience with modern state management solutions

Experience with Storybook

Understanding of SEO and server-side rendering

Experience working in an early-stage or rapidly growing Saa S 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 recent feature from scratch and improving an existing codebase.
