Frontend Engineer

We’re looking for a Senior Frontend Engineer to help us build the next generation of Flo’s platform and user experiences.

You’ll work on the foundation that powers interactive surveys and dynamic content inside the Flo app — building SDKs, reusable components, and internal tooling that enable other product teams to deliver exceptional experiences quickly and reliably.

Our frontend stack is based on React, TypeScript, and Next.js, with a strong focus on performance, maintainability, and testing.

We care deeply about quality: we use TypeScript for type safety, Jest and Playwright for automated testing, and continuously evolve our design system and UI Kit.

• Design, build, and maintain high-quality user-facing components and platform SDKs that enable survey and interactive experiences in the Flo ecosystem.
• Collaborate with product, design, and backend engineers to deliver flexible and scalable solutions.
• Contribute to Flo’s design system and shared UI libraries, ensuring consistency and reusability across products.
• Refactor and improve existing codebases for performance, reliability, and maintainability.
• Write clean, modular, well-documented code and advocate for engineering best practices.
• Actively participate in the frontend community at Flo, sharing ideas and driving improvements in architecture and development processes.

• 7+ years of experience building, shipping, and maintaining modern web applications.
• Expert-level knowledge of HTML, CSS, and JavaScript (ES6+).
• Deep experience with React and modern frontend tooling.
• Solid grasp of object-oriented design patterns and the ability to write efficient, well-structured algorithms
• You must use AI coding agents as your default way of working — writing code manually is the exception, not the rule.
• Proven ability to create adaptive, responsive, and accessible user interfaces.
• A product mindset and strong collaboration skills — you care about how your work impacts the user.

Nice to have

• Familiarity with Next.js, Contentful, or similar frameworks and CMS solutions.
• Experience with A/B testing and experimentation frameworks.
• Understanding of analytics and BI integrations.

• Competitive salary and annual reviews
• Opportunity to participate in Flo’s performance incentive scheme
• Paid holiday, sick leave, and female health leave
• Enhanced parental leave and pay for maternity, paternity, same-sex and adoptive parents
• Accelerated professional growth through world-changing work and learning support
• In-person collaboration and work in a hybrid model, with 3 days per week spent in the office
• 5-week fully paid sabbatical at 5-year Floversary
• Flo Premium for friends & family, plus more health, pension and wellbeing perks
