    What you will do

    • Build and iterate on modern web apps using Next.js, React, and TypeScript.
    • Own UI quality end to end: performance, accessibility, SEO, reliability, and maintainability.
    • Ship quickly without breaking things: use automated checks plus visual testing to catch UI regressions.
    • Experiment fast, validate outcomes, then harden into solid production code.
    • Collaborate in a senior, low process team: clear specs, tight feedback loops, high standards.
       

    Must have

    • 5+ years building products in team settings (we will deep dive into what you built and the impact).
    • Strong Next.js and React experience, plus TypeScript fluency.
    • Strong engineering hygiene: clean architecture, code reviews, pragmatic testing, and performance thinking.
    • Proven ability to deliver fast and safely under real world constraints.
    • AI native workflow: you actively use AI coding agents for implementation speed, but you can also enforce correctness via tests, types, and review discipline.
    • Extreme ownership is part of our culture.

       

      Quality and tooling expectations

    • Automated testing mindset (unit, integration, and E2E where it makes sense).
    • Visual regression testing workflow.
    • Solid CI discipline, ideally with preview environments per branch or PR.
    • Nice to have
    • Fullstack experience, or strong interest in moving there (Node.js or Python API work, data flows, auth, payments).
    • Experience operating apps with meaningful traffic and uptime requirements (observability, incident hygiene, rollbacks).
    • Deployment and infra exposure: Vercel, AWS, GCloud, Kubernetes, CI/CD.
    • Orchestration experience (workflows, background jobs, event driven systems)

       

      Bonus points

    • You have led small teams, mentored developers, or run your own product or company.
    • You can balance speed with taste: you know when to prototype and when to engineer.

    We run high-volume lead generation campaigns across France, Belgium, and Germany using Facebook ads. We need a frontend developer who has hands-on experience building landing pages that stay live and converting in hostile environments.

     

    This is not a normal frontend role. If you've only built marketing pages on Webflow or WordPress, this isn't for you.

     

    What you'll actually be doing:

    • Building landing pages that collect leads (name, phone, email) and don't get flagged by Google Safe Browsing, Microsoft SmartScreen, or browser security extensions (Avast, Norton, Malwarebytes, McAfee)
    • Implementing DOM cloaking β€” dynamic form rendering, field name rotation, behavioral gating so automated scanners can't easily parse the page
    • Detecting when security extensions are present in the user's browser and serving cleaner page variants to avoid heuristic blocking
    • Designing and maintaining cloaking systems that serve different content to crawlers/bots vs real users
    • Domain rotation workflow β€” we burn through domains regularly. You need to be comfortable deploying to new domains fast, managing SSL, and keeping pages live
    • Rapid iteration when something gets flagged β€” diagnosing what triggered detection and pushing fixes within hours, not days
    • Working with our existing stack: HTML/CSS/JS landing pages deployed on Azure VMs with Caddy

     

    Must-have experience:

    • You've had pages flagged by Safe Browsing or browser extensions and you fixed them. Not theoretically β€” actually
    • You understand how Google classifies pages as "deceptive" and what triggers it (UI patterns, script behavior, domain reputation, not just malware)
    • You've built or worked with cloaking systems (bot vs human detection, UA/IP filtering, JS-based fingerprinting)
    • You can write obfuscated/anti-analysis JavaScript that still works cleanly for real users
    • You're comfortable with domain rotation and rapid redeployment infrastructure
    • You can detect browser extensions (injected DOM elements, intercepted requests, timing differences) and adapt page behavior accordingly

     

    Nice to have:

    • Experience with Facebook ad landing pages specifically
    • Familiarity with European lead gen (FR/BE/DE markets)
    • Knowledge of Caddy, aaPanel, or CyberPanel for server management
    • Experience with call tracking integrations (Dialics or similar)

    T

    he reality:

    This work sits in a gray area. Platforms flag lead-gen pages even when the business behind them is legitimate. The job involves constant iteration β€” rotating domains, adjusting code, staying ahead of detection systems. If that makes you uncomfortable, no hard feelings, but this isn't the right fit.

    If you've done this kind of work before, you know exactly what I'm describing. And you probably don't put it on your CV. That's fine β€” just show me you can do it.

     

    To apply, answer these two questions:

    1. Describe a specific time a page you built got flagged or blocked. What triggered it and what did you do?
    2. How would you detect if a user has Avast or Norton's browser extension installed, and what would you change on the page?

     

    Don't send generic proposals. If your answer is "I would check Google Search Console," this isn't the role.

    We’re looking for a Senior Frontend Developer for an all-in-one SaaS platform that helps agencies and creators manage large-scale social media operations.
    Today, these teams rely on spreadsheets, Discord, and multiple disconnected tools to handle scheduling, payroll, analytics, and communication. The platform replaces all of that with one centralized system.
    Think of it as: workforce management + scheduling + payroll + analytics + messaging + automation in a single web app.
    This is an operations-focused product built around dashboards, real-time systems, and complex business logic rather than a marketing-oriented application.
    You will help build a scalable web platform with team and role management for large organizations, shift scheduling and availability planning, time tracking, and automated payroll with bonuses and commissions. The system includes performance and sales analytics dashboards, real-time messaging, workflow automation, and role-based access control. It also supports integrations with external platforms and high-volume data processing and reporting.

    Team: 3x Backend Developers, 3x Frontend Developers, Solution Architect, PM, BA, QA, DevOps, Designer

    Requirements:

    • 5+ years of experience in JavaScript, TypeScript, React
    • Valid, cross-browser, and high-quality layout
    • Strong expertise in HTML and CSS
    • Strong expertise in ECMAScript and the DOM API
    • Strong expertise in React (concurrent features,  composition and compound patterns, compiler)
    • Strong knowledge in CSS Modules, TailwindCSS, Radix Ul/Base UI, Shadcn/ui
    • Strong expertise in Tanstack Router and Tanstack Query
    • Experience with Zustand, Tanstack Form, Recharts/ECharts
    • Strong expertise in performance optimization and UX improvements (code splitting, bundle size, virtualization, CLS, LCP, optimistic updates)
    • Experience with a11y (keyboard accessibility, screen reader compatibility, zoom and user preferences)
    • Experience with real-time data (WebSocket, SSE)
    • Experience with AI agents usage (Claude Code/Codex CLI/Gemini CLI)
    • Upper-intermediate English level
       

    Nice to have:

    • Experience with Vitest, Testing Library, Playwright, Storybook
       

    Responsibilities:

    • Build and scale a complex frontend application from scratch
    • Contribute to frontend architecture (state, data flow, performance)
    • Deliver dashboards and workflow-heavy features: scheduling, time tracking, payroll flows, analytics
    • Implement integrations and automation flows
    • Collaborate closely with backend & product on business-critical features
       

    What we offer: 

    • Remote work format and flexible schedule
    • Autonomy in work, opportunity to build processes, and grow within the company
    • Individual development plan and annual performance review
    • Workshops and playgrounds for continuous learning
    • Compensation for subject-matter training
    • Corporate English classes
    • Access to IT Loyalty Club
    • Accounting support
    • 18 working days of annual leave
    • 7 working days of sick leave and 7 working days of unpaid leave

This is a full-time remote opportunity for a highly senior frontend engineer who can take ownership of frontend systems end to end and comfortably collaborate with backend services, without being expected to work deeply on backend implementation.

     

    This role is ideal for someone who enjoys ownership, product thinking, and building scalable, maintainable frontend systems used in real production environments, while having a solid understanding of how frontend applications interact with APIs and data layers.

     

    Responsibilities:
     

    • Architect, develop, and maintain complex frontend applications using React and TypeScript
    • Build scalable, reusable UI architectures within a monorepo setup
    • Work end-to-end on frontend features, from requirements and UI logic to API integration and production readiness
    • Collaborate closely with backend engineers, integrating with NestJS-based APIs and ensuring clean, well-typed contracts
    • Take ownership of frontend architecture, technical decisions, and long-term maintainability
    • Ensure high performance, accessibility, and responsiveness across applications
    • Improve frontend reliability through testing, code reviews, and best practices
    • Work closely with product managers and designers to translate requirements into high-quality user experiences
    • Contribute to shared tooling, libraries, and frontend standards within the monorepo
    • Write clean, readable, and well-structured code with a strong focus on quality and maintainability
       

    Requirements:
     

    • 7+ years of commercial engineering experience (senior-level only)
    • Expert-level knowledge of React and TypeScript
    • Strong understanding of modern frontend architecture, state management, and performance optimization
    • Experience working in monorepo environments (Nx, Turborepo, or similar)
    • Working knowledge of backend concepts, including APIs, data flows, and basic database interactions
    • Experience consuming and integrating with well-typed APIs (REST / GraphQL)
    • Strong sense of ownership and responsibility for delivering production-ready features
    • Ability to work independently in distributed, remote teams
    • Clear communication skills and a pragmatic, problem-solving mindset
       

    What We Offer:
     

    • Fully remote, flexible work culture with long-term stability
    • High-impact product work with modern technologies
    • Strong engineering standards and real technical ownership
    • Supportive, transparent team culture with no micromanagement

    Competitive monthly compensation, aligned with experience and contribution


    How to Apply:

     

    Please send a short blurb about yourself β€” and tell us your favorite ice cream flavor (mine is cherry πŸ’)
