Position Overview

PayFit is seeking an Intermediate Software Engineer with a strong Frontend focus to join the Company Setup & Structure, a key team within the Company & Employee Experience tribe. Our mission is to help admins manage their company's full lifecycle—from setup to activation and beyond—through simple, inclusive experiences that save time and support growth.

You will work on:

• Core company lifecycle features: Company setup/self-onboarding, compliance checks, fraud detection, and multi-establishment management

• User-facing experiences: Building intuitive React interfaces that simplify complex workflows for admins managing multiple related companies

• Backend systems: Contributing to event-driven microservices, APIs, and domain events used across PayFit's platform

The domain spans three countries (France, Spain, UK) and offers strategic challenges around scalability, cross-country data management, and compliance automation.

Your mission will be to design and deliver high-quality, maintainable, and user-centric software while collaborating closely with Product, Design, and Engineering teams to

drive technical excellence and business impact.

What you'll do

Frontend Development

• Design and build scalable, user-facing interfaces for company lifecycle management (onboarding, setup, compliance flows, fraud detection) using React and TypeScript

• Collaborate closely with our Designer and Product Manager to deliver intuitive features that improve company setup, self-onboarding flows, and compliance automation

• Structure and deliver exceptional user experiences, ensuring accessibility, performance, and maintainability across our product

• Ensure code quality and best practices across our frontend codebase through testing, code reviews, and documentation

• Participate in code reviews, promoting best practices in component architecture, state management, and UI/UX patterns

Backend Development

• Contribute to architectural decisions and technical excellence across the squad's systems

• Ensure testing, observability, and reliability of backend services

• Participate in code reviews, promoting best practices in distributed systems, APIs, and data integrity

• Collaborate with other squads to expose domain events and APIs consumed across PayFit's platform

Cross-functional Collaboration

• Work closely with Product and Design from discovery to delivery to translate user needs into technical solutions

• Participate in squad rituals (planning, retros, demos) and contribute to continuous improvement

• Mentor junior engineers occasionally through code reviews and knowledge sharing

• Communicate progress, blockers, and trade-offs clearly to technical and non-technical stakeholders

This role is for you if

• You have 3-5 years of software engineering experience with a strong focus on frontend development

• You're expert-level with React and TypeScript — you've built production-grade interfaces and deeply understand component architecture, state management, performance optimization, and modern frontend patterns

• You have solid backend experience with TypeScript/Node.js — you're comfortable building and maintaining RESTful APIs, async workflows, and microservices

• You have hands-on experience with event-driven architectures — you've worked with messaging systems (Kafka, SQS, RabbitMQ, EventBridge) and understand asynchronous patterns, eventual consistency, and resilience

• You have cloud experience (AWS preferred) — familiar with deploying and operating services (Lambda, ECS/Fargate, RDS, S3, CloudWatch) and basic infrastructure-as-code concepts

• You write clean, tested, and maintainable code — you understand the importance of testing (unit, integration, e2e) and use CI/CD pipelines regularly

• You're a strong collaborator — you thrive working with Product Managers and Designers, actively participating in discovery and translating user needs into technical solutions

• You have an ownership mindset — you take end-to-end responsibility for your work, from design to production monitoring, and proactively communicate progress and blockers

• You're fluent in English (conversational/professional level required) — our team is international and English is the working language

It would be great if you also:

• You are comfortable collaborating with infra/platform teams, and have experience improving developer experience and CI/CD pipelines.

• Have experimented with GenAI or emerging technologies and can share how they might shape developer workflows.
