AI-Native SaaS Platform | Backed & Scaling | Global Team
Stax is partnering with a well-funded, AI-native SaaS company redefining how modern organisations collaborate across product, engineering, support, and customer teams. This company is building an intelligent platform designed to unify structured and unstructured data into a single AI-ready foundation. Rather than adding more tools to the stack, their mission is to create a system where human‑AI collaboration becomes seamless, contextual, and genuinely useful. The result? Teams spend less time navigating software and more time solving meaningful problems.
Backed by top‑tier venture capital and operating globally, the company has scaled to hundreds of employees across multiple international hubs and continues to expand its engineering organisation.
The Opportunity
As a Senior Frontend Engineer, you will shape the architecture, craftsmanship, and developer experience of a modern AI‑native platform used by global enterprises. This is not a feature factory role. You will influence platform‑level decisions, design systems, and front‑end architecture that power high‑velocity product teams.
What You’ll Work On
- Architecting the Frontend Platform
- Define patterns, conventions, and tooling across a React + TypeScript ecosystem
- Ensure modularity, scalability, and long‑term maintainability
- Drive micro‑frontend strategy for independent feature velocity
- Design System & Component Architecture
- Evolve a scalable, themeable component library
- Define and maintain design tokens and accessibility standards
- Improve Storybook workflows and UI consistency across products
- Build performant frameworks capable of rendering large datasets
- Develop real-time dashboards and advanced visualisations
- Embed AI‑assisted insights directly into the UI layer
- Improve CI/CD pipelines and test strategies
- Enhance local development speed and reliability
- Raise standards across linting, documentation, and tooling
Technical Leadership
- Review architecture and critical PRs
- Facilitate design and architecture workshops
Tech Environment
- React
- TypeScript
- Vite
- Next.js
- WebAssembly (including edge‑based analytics engines)
- Storybook
- Tailwind CSS
- Jest
- Cypress
- Playwright
What We’re Looking For
- 8+ years building large‑scale web applications
- Strong experience in modular front‑end architecture and micro‑frontends
- Proven delivery of data‑intensive, real‑time interfaces
- Deep TypeScript expertise and modern CSS methodologies
- Passion for developer experience and technical craftsmanship
Nice to Have
- WebSockets / real‑time collaboration expertise
- PWA experience with offline resilience
- Design token pipelines or themeable UI frameworks
- High velocity with strong code review standards
- Performance as a product metric (TTI, bundle size, UX responsiveness)
- Distributed, globally collaborative team
- Ownership from architecture through iteration
If you care deeply about front‑end architecture, modular systems, and building AI‑native interfaces that feel intelligent and fast — this is a rare opportunity to influence a platform at meaningful scale. Apply directly or reach out to Stax for a confidential conversation.
