WegoPro is a business travel platform that helps organizations manage corporate travel through an integrated system combining booking, approvals, policy, payments, and reporting. As a Senior Frontend Engineer, you'll own the architecture and evolution of the frontend platform serving travel managers, finance teams, and business travelers globally. In this hands-on senior role, you'll have significant technical ownership across multiple domains. You'll architect and maintain the frontend platform including design systems, application state management, routing, build tooling, and performance optimization. You'll build scalable frontend systems on top of microservices architecture, designing resilient API integrations, caching strategies, and graceful failure handling. A key focus is developing AI-powered product experiences—conversational booking interfaces, agentic workflows, and streaming interactions that make AI feel reliable and trustworthy to users. You'll drive adoption of AI-assisted development tools across the engineering team, helping define best practices for Claude Code, Cursor, and similar tools. Leadership responsibilities include leading technical design discussions, conducting thoughtful code reviews, and mentoring engineers to raise overall code quality. You'll own software quality end-to-end: automated testing, observability, CI/CD pipelines, and operational excellence on AWS infrastructure. Required qualifications include significant experience building modern web applications with deep expertise in complex, stateful single-page applications. You need expert-level knowledge of Vue 3 (Composition API, Pinia, Nuxt) and strong TypeScript skills. Modern frontend tooling experience is essential: Vite, code splitting, performance optimization, and Core Web Vitals. You should have daily hands-on experience with AI coding agents and familiarity with modern AI application development patterns including MCP, agent frameworks, and context engineering. AWS experience (S3, CloudFront, Lambda, ECS, CI/CD, feature flagging) is required. Strong communication and collaborative mindset with bias toward ownership and delivery round out the profile. Nice-to-have experience includes business travel, fintech, or B2B SaaS domain knowledge; micro-frontend architectures; design system work; and open-source contributions in Vue or AI tooling ecosystems. You'll solve meaningful engineering challenges spanning global travel inventory, multi-currency pricing, enterprise policy engines, and large-scale integrations within a collaborative team where technical decisions have lasting impact.
