Frontend Design Engineer | Figma + React/TypeScript
Full-time · Remote · 0.5–3 years of experience
₹4–8 lakh per year + ESOPs
Who we are
We’re Alpha, building an AI-native workspace for go-to-market teams. We care about thoughtful product design and the engineering that makes it work: clear information, useful interactions and interfaces that remain reliable as workflows become more complex.
What we’re building
Alpha brings contacts, a unified inbox, campaigns, knowledge and AI-assisted creation into one workspace. These connected workflows present real design challenges: helping users navigate information, manage conversations, move between views and understand what’s happening at every step.
We’re looking for someone who enjoys turning that complexity into an interface people can understand and use confidently.
The role
You’ll work across product design and frontend engineering, taking a feature from user flows and Figma designs through to a working React implementation.
Both sides matter. You should be comfortable making visual and interaction decisions, then translating them into reusable components, responsive layouts and well-managed application state. Your work should feel considered in the details and hold up beyond the happy path.
Key responsibilities
- Design user flows and interfaces in Figma with clear hierarchy, thoughtful interactions and consistent visual details
- Build those experiences in React and TypeScript, carrying the design intent through to the finished interface
- Create and maintain reusable Figma and frontend components
- Implement API integrations, asynchronous interactions and shared state across screens and views
- Handle loading, empty, error and recovery states, keyboard access and different screen sizes
- Work with the team to clarify requirements, discuss trade-offs and iterate on features
- Test your work, investigate bugs and improve usability and reliability
What we’re looking for
- Hands-on ability in both Figma product design and frontend development
- Strong fundamentals in React, TypeScript, HTML and CSS
- A good eye for typography, spacing, hierarchy and interaction design
- Familiarity with component-based development, state management and API integration
- Portfolio or reference work showing what you personally designed and built
- The ability to explain your decisions, code and contribution clearly, including where teammates or AI tools helped
Good-to-have skills
- Experience with SaaS, CRM, AI or workflow-heavy products
- Familiarity with Vite, Tailwind CSS and design systems
- Experience with data-rich interfaces such as tables, boards, filters and detail panels
- Experience with frontend testing and accessibility
What we offer
- Full-time remote work
- Competitive compensation within a ₹4–8 lakh annual salary band
- Equity through ESOPs
- Ownership across design and implementation, with a direct contribution to how Alpha’s product works and feels
How to apply
Share your portfolio or relevant reference work, along with a working demo and code or a code walkthrough where available. Briefly explain what you owned, one important design or engineering decision, and what you would improve next.
