React Engineer – AI-Powered Interfaces

2 weeks ago

London, Greater London, United Kingdom Fiskl | Autonomous Accounting Full time £60,000 - £120,000 per year

Build Interfaces That Make AI Feel Like Magic

We're at 80% automation today, building toward 95% autonomous accounting. Now we need someone to make that complexity feel simple. If you believe the best interface is no interface, and that AI should anticipate needs not wait for clicks, this is your role.

The Mission

Create React interfaces where AI does the heavy lifting and humans just approve. Build experiences so intuitive that accountants who still use Excel become power users in minutes.

What You'll Build

  • Real-time dashboards that update as AI processes millions of transactions.
  • Conversational interfaces where SME owners ask "what can I afford?" and get instant answers.
  • Intelligent forms that complete themselves using AI predictions.
  • Mobile-first experiences that work flawlessly on any device.
  • Data visualizations that make complex financial data instantly understandable.
  • Collaborative interfaces where accountants and clients work simultaneously.

Non-Negotiable: You Must Code with AI

We only hire engineers who are highly proficient with AI tools. You should be using Claude/GPT-4/Copilot daily to ship 3-5x faster than traditional development. If you don't actively code with AI, this role isn't for you.

Technical Requirements

  • Production React experience (we care more about what you've built than years)
  • Strong TypeScript skills and modern React patterns (hooks, context, suspense)
  • Production experience with React frameworks , Vite, Remix, etc.)
  • Proven proficiency with shadcn/ui and component composition
  • Experience integrating with backend APIs and real-time data
  • Strong understanding of performance optimization
  • Eye for design and UX without needing hand-holding

Our Stack

  • React + TypeScript for everything frontend
  • shadcn/ui for components, open-source libraries where they excel
  • Vercel for deployment and edge functions
  • AWS Bedrock for AI integrations
  • Real-time updates via WebSockets

What Makes You Different

  • You ship production code with AI assistance daily.
  • You compose existing libraries rather than reinventing wheels.
  • You can turn complex requirements into simple interfaces.
  • You think in user journeys, not just features.
  • You understand Vercel's deployment model and optimize for it.
  • You balance perfectionism with shipping.

The Opportunity

The accounting industry is a $88B market where the "modern" interface is still a digitized paper ledger. QuickBooks looks like Windows 95. Xero thinks tabs are revolutionary.

This is your chance to build the interface that makes AI-powered accounting feel inevitable, not intimidating. To create experiences so good that switching back to traditional software feels like going back to dial-up internet.

Interview Process

  • Portfolio review focusing on production React applications.
  • Live coding with AI tools to build a financial dashboard component.
  • Discussion of your AI-assisted development workflow.
  • Technical deep-dive on performance and architecture decisions.

What We Offer

  • Competitive salary based on experience.
  • Build the future of AI-powered accounting interfaces.
  • Work with cutting-edge AI models and infrastructure.
  • Remote-first with quarterly team meetups (not quarterly sprints).
  • Direct impact on millions of global users.

To Apply

Show Us

  • Production React applications you've built.
  • How you use AI tools to accelerate development.
  • A shadcn/ui based component or project.
  • Your approach to making complex data simple.

If you want to build another CRUD app with forms and tables, this isn't for you. If you want to create interfaces that make people rethink what software can do, let's talk
