ABOUT THE TEAM
At SMP Mobility (soon to be Vend), we help our users make smarter decisions by providing real, actionable insights throughout their journey. Our Insight as a Product team builds end-user insight products on top of rich, structured datasets — and we’re now looking for a Frontend Senior Developer to shape how these insights are delivered at scale.
ABOUT THE ROLE
You will lead the architectural direction of our frontend applications and data-driven UI experiences, ensuring performance, usability, and long-term maintainability. You’ll work in a product team with developers, product manager, analyst and designers to build seamless, high-impact user experiences that make complex data accessible and useful.
This is a hands-on role for a frontend technologist who’s passionate about designing and developing for performance, building scalable design systems, and mentoring engineers.
Additionally:
- Own the frontend architecture strategy and implementation for insight-driven products.
- Design and develop scalable, maintainable, and performant UIs using React, Next.js, and TypeScript.
- Collaborate to translate complex data structures into intuitive UIs.
- Build reusable components and work in collaboration with designers.
- Optimize for data-heavy interfaces — including real-time data visualizations, dashboards, and interactive reporting tools.
- Set engineering standards for frontend development (testing, accessibility, performance, and CI/CD practices).
- Review code, build/improve frontend competency, and guide technical decisions in the teams.
- Lead the adoption of new technologies, frameworks, and tools as appropriate.
ABOUT YOU
- frontend development experience, including architecting complex web applications.
- Deep expertise in React, Next.js, and TypeScript.
- Strong understanding of component-based architecture, state management, and API integration.
- Experience building and maintaining design systems and component libraries.
- Skilled at optimizing frontend performance, especially in data-intensive environments.
- Strong UX and accessibility instincts — able to partner well with product and design.
- Comfortable working with CI/CD, frontend testing frameworks, and modern tooling (e.g., Vite, Storybook, Jest, Playwright).
- Experience with data visualization tools or libraries (e.g., Recharts, D3, Highcharts) is a big plus.
- Excellent communication and collaboration skills; able to mentor and lead cross-team frontend efforts.
- Bonus: Familiarity with data privacy, analytics, or domain modeling in frontend contexts.
WHY THIS ROLE MATTERS:
- You’ll define how users interact with our most important asset — insight.
- You’ll build tools that help people understand and act on complex data.
- You’ll enable our team to move faster and build better with a strong frontend foundation.
- You’ll shape the look, feel, and performance of our product for years to come.
