Senior Frontend Developer (React, Next.js)

About the Position

We're seeking a Senior Frontend Developer with expertise in React and Next.js to join our team in Białystok, Poland, for a remote position.

Responsibilities

• Own frontend architecture: state, data fetching, component boundaries, and SSR/SSG/ISR vs client rendering decisions; align with the design system approach
• Build the new e-commerce frontend: purchase flow, customer dashboard (diet calendar, plan changes, payments), and later tools for production and logistics
• Maintain production performance, availability, and quality: Core Web Vitals, error monitoring, and tests that catch real issues
• Deliver end-to-end features with backend and business (including Node.js and API work when needed)
• Work spec-first with everyday AI tools while maintaining quality
• Improve team capability through demos, learning, and code reviews

Requirements

• Minimum 4 years of commercial experience, including strong React + TypeScript in customer-facing products
• Production Next.js experience: routing, caching, and correct server/client rendering decisions (SSR/SSG/ISR)
• Ability to design and defend a testing strategy (unit vs integration vs e2e, plus what not to test)
• Strong performance and accessibility instincts (Core Web Vitals, avoiding keyboard/screen reader blockers)
• Ownership mindset to drive features end-to-end and return to business and design with questions
• Communicative Polish language skills

We Offer

• Employment with a dynamically growing industry leader in Poland
• Compensation aligned with experience and skills
• Real impact on frontend architecture and working approach (team is still being formed)
• Large-scale greenfield development in a stable company
• Remote work from Poland; office option in Białystok
• Benefits package (Medicover Sport subsidy, private medical care, PZU insurance, discounts on Kuchnia Vikinga products)
