Software Engineer - Frontend focus Full-stack

We're looking for a frontend-first full-stack engineer to build and evolve the employee experience across our platform. The Employee Management team owns the key journeys where users create, manage, and update employee data throughout the employee lifecycle.

This is a full-stack role aligned with team priorities: you'll contribute wherever the work is, across frontend and backend. At the same time, you bring a strong frontend background and will help the team level up on UI quality, frontend architecture, and product experience standards.

What you will do

Deliver product work end-to-end: discovery, technical design, implementation, rollout, iteration.

• Build high-quality, user-centric interfaces: accessible, performant, consistent.
• Take ownership of frontend architecture and patterns (state management, data fetching, routing, error handling, forms) to improve quality and speed sustainably.
• Collaborate on backend implementation when needed (services, endpoints, integrations) to ship team priorities.
• Improve our design system usage and help scale UI consistency across flows.
• Raise the bar on engineering quality through reviews, pairing, and pragmatic technical leadership.

Backend collaboration & API design

A key part of the role is ensuring the end-to-end experience is high quality. You'll work with the team to design and evolve APIs that are:

• predictable and consistent,
• optimized for product usage (latency, pagination, partial updates),
• resilient (validation, error semantics, backwards compatibility),
• and easy to consume from the frontend.

You won't be "the backend owner", but you will be expected to contribute when needed and help drive API choices that directly impact user experience., Employee Management sits at the heart of the platform. The quality of these journeys impacts daily workflows for customers and sets the bar for the rest of the product. This role combines strong ownership of team delivery with a clear mandate to elevate frontend quality and user experience., Learning & Development: In PayFit we have a great learning platform where you can learn new skills every day with the support of our company. We also have English language courses to improve your business communication vocabulary and get to the next level.

Career Development: We want you to progress and be free to choose which direction you want to grow. There are also opportunities for internal moves.

Do you have experience in TypeScript?, * Strong experience building modern web apps with React (or similar) and TypeScript.

• Proven ability to deliver full-stack work, prioritizing the most valuable outcomes for the team.
• Strong product sense and attention to UX details (edge cases, empty states, error states, loading states).
• Ability to influence frontend quality and help others level up (patterns, reviews, examples, shared components).
• Comfortable collaborating with PM/Design and across engineering.

Nice to have

• Experience with design systems/component libraries at scale.
• Frontend observability experience (error tracking, monitoring, performance metrics, web vitals).
• Experience in complex B2B workflows (permissions, audits, multi-step flows).
• Experience in improving the reliability and maintainability of a mature codebase
