About CONXAI
CONXAI has built an agentic AI platform for the Architecture, Engineering and Construction (AEC) and physical industries, focused on knowledge-automation. We automate high-stakes, knowledge-intensive workflows traditionally trapped in siloed data, fragmented tools, and tacit (undocumented) human expertise.
Our multi-agent systems perform complex reasoning in the physical world; and transform bespoke, service-heavy processes into scalable Service-as-a-Software automation.
CONXAI is trusted by some of the leading AEC companies in Europe, US, LATAM, and Japan.
Your Role
As 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.
You 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.
Responsibilities
Architect & Build at Scale

- Work within a structured Feature-Sliced Design (FSD) architecture
- Design clean domain boundaries and public APIs between layers
- Build reusable features, widgets, and domain entities
- Maintain architectural integrity using dependency rules and validation tools
Deliver High-Quality Code
- Write type-safe, production-grade TypeScript
- Implement unit & integration tests (Jest, React Testing Library)
- Optimize performance, bundle size, and rendering efficiency
- Implement robust error handling and monitoring
Build Advanced Product Capabilities
- Implement efficient server-state management with TanStack Query
- Work on complex UI patterns
- Collaborate on AI feature integration (LLM workflows, structured outputs)
Collaborate & Lead
- Work closely with backend engineers on RESTful APIs
- Contribute to architectural decisions and technical planning
- Conduct thoughtful code reviews
- Mentor mid/junior engineers on architecture and best practices
Requirements
Required
- 5+ years of professional frontend experience
- Advanced React & TypeScript expertise
- Strong architectural thinking (FSD, Clean Architecture, or similar)
- Experience with modern state management
- Strong testing mindset (unit & integration)
- Experience integrating REST APIs
- Strong written and verbal English communication skills
- High standards for code quality and maintainability
Highly Valued
- Experience building complex B2B SaaS products
- Knowledge of scalable frontend architecture patterns
- Experience with performance optimization
- Experience with AWS (Cognito / Amplify / S3 / CloudFront)
Nice to Have
- Experience in AEC, construction, or document-heavy domains
- Exposure to AI/ML integrations in frontend applications
- PDF rendering or document processing experience
We Offer
- Edge of Innovation: Be at the absolute forefront of AI in the construction tech space
- High Autonomy: Own the product strategy and shape a product that directly impacts the industry
- Top-Tier Peer Group: Work with a global team of ML engineers, software engineers, and industry practitioners
- Equity & Scale: Competitive compensation with significant equity upside
