We automate high-stakes, knowledge-intensive workflows traditionally trapped in siloed data, fragmented tools and tacit (undocumented) human expertise.\nOur multi-agent systemsperform complex reasoning in the physical world; and transform bespoke, service-heavy processes into scalable Service-as-a-Softwareautomation.\nCONXAI is trusted by some of the leading AEC companies in Europe, US, LATAM and Japan.\nYour Role\nAs a Senior Frontend Engineer, you will play a key role in shaping and evolving a modern, scalable frontend architecture within a complex B2B AI platform.\nYou won’t just implement features - you’ll design systems. You’ll think in terms of structure, boundaries, and long-term sustainability. Your focus will be on building robust, maintainable solutions that can grow with the product and the organization.\nThis role is ideal for someone who:\nTakes ownership of architectural decisions\nValues clean abstractions and clear domain boundaries\nThinks beyond short-term delivery toward long-term scalability\nEnjoys collaborating across teams to align technical direction\nSees frontend engineering as system design, not just UI implementation\nYou will influence how the frontend evolves, contribute to technical standards, and help ensure the platform remains scalable, testable, and maintainable as it grows.\nWhat You’ll Do\nArchitect & Build at Scale\nDevelop complex B2B features using React 18 + TypeScript\nWork within a structured Feature-Sliced Design (FSD)architecture\nDesign clean domain boundaries and public APIs between layers\nBuild reusable features, widgets, and domain entities\nMaintain architectural integrity using dependency rules and validation tools\nDeliver High-Quality Code\nWrite type-safe, production-grade TypeScript\nImplement unit & integration tests (Jest, React Testing Library)\nOptimize performance, bundle size, and rendering efficiency\nImplement robust error handling and monitoring\nBuild Advanced Product Capabilities\nImplement efficient server-state management with TanStack Query\nWork on complex UI patterns\nCollaborate on AI feature integration (LLM workflows, structured outputs)\nCollaborate & Lead\nWork closely with backend engineers on RESTful APIs\nContribute to architectural decisions and technical planning\nConduct thoughtful code reviews\nMentor mid/junior engineers on architecture and best practices\nOur Tech Stack\nReact 18 + TypeScript 5.5+\nFeature-Sliced Design (layered architecture)\nTanStack Query + Zustand\nMaterial-UI (MUI v5) + Emotion\nSCSS Modules\nWebpack 5\nAWS Amplify & Cognito\nJest + React Testing Library + MSW\nCI/CD pipelines with automated testing\nWhat We’re Looking For\nRequired\n5+ years of professional frontend experience\nAdvanced React & TypeScript expertise\nStrong architectural thinking (FSD, Clean Architecture, or similar)\nExperience with modern state management\nStrong testing mindset (unit & integration)\nExperience integrating REST APIs\nStrong written and verbal English communication skills\nHigh standards for code quality and maintainability\nHighly Valued\nExperience building complex B2B SaaS products\nKnowledge of scalable frontend architecture patterns\nExperience with performance optimization\nExperience with AWS (Cognito / Amplify / S3 / CloudFront)\nNice to Have\nExperience in AEC, construction, or document-heavy domains\nExposure to AI/ML integrations in frontend applications\nPDF rendering or document processing experience\nWhy CONXAI\nEdge of Innovation:Be at the absolute forefront of AI in the construction tech space\nHigh Autonomy:Own the product strategy and shape a product that directly impacts the industry\nTop-Tier Peer Group:Work with a global team of ML engineers, software engineers and industry practitioners\nEquity & Scale:Competitive
