Javascript Developer

Frontend Design Engineer

About Alpha

Alpha is an AI-native outreach and relationship intelligence platform. We bring contact management, multi-channel communication, knowledge, and campaign orchestration into one connected workspace.

We’re looking for a product-minded frontend engineer who can turn complex workflows into polished, intuitive experiences. This is an engineering-first role: strong design judgment is a valuable differentiator, but formal design experience is not required.

What you’ll do

• Build and ship production features across data-rich workflows, including contacts, inbox, knowledge, onboarding, settings, and AI-powered creative tools
• Turn product requirements and designs into responsive, accessible, high-quality interfaces
• Work across the full frontend lifecycle—from shaping interactions and component APIs to implementation, testing, and refinement
• Create reusable components and evolve our shared design system
• Make thoughtful decisions about hierarchy, spacing, states, motion, and interaction details
• Build performant tables, forms, side panels, editors, drag-and-drop experiences, and other complex product surfaces
• Manage server state, mutations, caching, loading states, errors, and optimistic interactions cleanly
• Collaborate closely with product, design, and backend engineers
• Improve frontend architecture, developer experience, accessibility, and performance
• Review frontend work and help maintain a consistent quality bar across the product

Our frontend stack

- React 19 and TypeScript

- React Router 7 and Vite

- Tailwind CSS 4

- shadcn/ui, Radix UI, and a shared component library

- TanStack Query, Table, and Virtual

- Zustand

- React Hook Form and Zod

- pnpm and Turborepo

You do not need experience with every tool on this list, but you should be comfortable learning within a modern, strongly typed React stack.

What we’re looking for

- Strong experience building and shipping production React applications

- Excellent TypeScript, JavaScript, HTML, and CSS fundamentals

- A solid understanding of component architecture, state management, data fetching, and frontend performance

- Experience building reusable components without over-engineering them

- Care for responsive behaviour, accessibility, edge cases, and interaction states

- The ability to work effectively in a component-driven design system

- Good product judgment and the ability to simplify complex workflows

- Comfort working independently, making sensible trade-offs, and taking features from idea to production

- Clear communication and a collaborative approach to product development

Bonus points

- Strong visual design instincts or experience working in Figma

- Experience owning both the design and implementation of product features

- A portfolio demonstrating polished, interaction-heavy product work

- Experience building design systems or shared component libraries

- Experience with data-dense B2B or SaaS applications

- Experience with animations, drag-and-drop interfaces, rich editors, diagrams, or generative AI products

- Familiarity with frontend observability and performance profiling

What success looks like

- You ship interfaces that feel clear, fast, and considered

- Your components are reusable, maintainable, and aligned with the wider product

- You can take an ambiguous workflow and turn it into a coherent user experience

- You raise the quality of the frontend through both your code and your product judgment

- You balance speed, polish, and technical quality without losing sight of the user

We value demonstrated ability over specific credentials. If you are a strong frontend engineer with an eye for good product experiences—even if you do not consider yourself a designer—we would like to hear from you.
