Role Description Websites are crucial for businesses—helping them get found and chosen online. Yet for many small businesses, websites become a burden. They launch with high hopes, spending countless hours on every little detail, aiming for perfection. But soon after launch... no more updates. The website sits untouched, slowly becoming outdated, broken, and buried by search engines, eventually joining the ranks of the "living dead" websites in the vast online cemetery. To address this issue, CentralApp (soon rebranding to stride-site.com ) is moving away from a template-first approach (such as Wordpress or Wix) and is developing an innovative method for website creation. This new approach integrates numerous pre-designed business modules, alongside a branding engine that offers millions of possibilities. This combination aims to deliver an optimal design and content with minimal effort. Our solution is currently used by thousands of businesses across Europe, mostly in France, Belgium, Italy & Spain. In addition to our website product, we offer a suite of tools designed to enhance your impact: - Integration Marketplace - Advanced Website Forms - Client inbox & clients list - Local SEO with Listing Management - Instagram Wall - Review Wall This is not a narrow frontend role. We are looking for a Product Engineer who can take a product problem, define the user experience, prototype quickly, implement the frontend, and collaborate with backend owners to ship the full solution. You should be strong enough on frontend to review React code yourself, pragmatic enough to make good product and design decisions, and technical enough to reason about backend architecture, API contracts, data flows, edge cases, and performance. You do not need to write production Haskell. However, you should be able to use AI effectively to explore backend logic, generate backend implementation proposals, define API contracts, and prepare work that can be reviewed by the engineers who own that layer. Qualifications - Strong frontend skills, particularly in React - Ability to prototype quickly - Experience with backend architecture and API contracts - Familiarity with AI tools for development Requirements - Own product features from problem definition to production delivery - Define user flows, product behavior, edge cases, and success criteria - Build and maintain scalable, modular, high-performance frontend code - Review frontend implementation independently, including UX, code quality, performance, accessibility, and maintainability - Prototype quickly to validate product ideas and technical directions - Define API contracts and backend expectations clearly - Use AI tools to accelerate prototyping, implementation, refactoring, testing, debugging, and technical exploration - Prompt AI to generate backend implementation proposals that backend owners can review, refine, and ship - Collaborate with backend engineers on architecture, data models, permissions, error handling, observability, and performance - Contribute to resilient systems, including monitoring, automated recovery, and self-healing workflows where relevant - Keep the end user, business impact, SEO, accessibility, and product quality in mind Benefits - Remote-first role with flexibility in how and where you work - High ownership with real influence over product direction and technical decisions - Flexible working setup focused on output, autonomy, and impact - Opportunity to work across product, design, frontend, backend architecture, and AI-assisted engineering workflows - Small, experienced team where strong contributors can move fast and have visible impact
