Senior Frontend Engineer (React / TypeScript)
Hoofddorp, Netherlands

About the role
We care less about titles and more about mindset and attitude. We're looking for a senior frontend engineer who is ready to take ownership of complex, user-facing surfaces and shape the next generation of our products. What matters most is a strong foundation, an eye for detail, and the drive to raise the bar across the team.
You'll work on PaymentIQ, a SaaS payment orchestration platform that helps merchants centrally manage, optimise, and scale payment flows across providers and markets. Through a single integration, PaymentIQ connects merchants to more than 300 payment service providers, reducing the cost and complexity of adding new providers, supporting expansion into new markets, and enabling flexible checkout experiences. As a senior frontend engineer you'll have a direct impact on the checkout, hosted fields, and back-office surfaces used by hundreds of merchants worldwide.
AI-First Engineering
We take an AI-first approach to engineering. Every engineer gets full access to a broad range of AI capabilities and is expected to use them to move faster, raise code quality, and reduce repetitive work. AI is part of how we build — not an optional add-on.
- GitHub Copilot Enterprise: premium chat, agentic coding agents, and automated code review across the IDE (JetBrains and VS Code), GitHub.com, and the CLI.
- Frontier models on tap: the latest Claude (Opus, Sonnet, Haiku) and GPT families, selectable per task with no individual quotas to worry about.
- Coding agents: delegate larger refactors, test generation, and investigation work to autonomous agents, with human review on every PR.
- Build your own tooling: we encourage engineers to write their own scripts, agents, and MCP integrations to automate the boring parts of the job.
Key responsibilities
- Build & Ship: Design, implement, and maintain frontend features across the PaymentIQ platform — checkout, hosted fields, and back-office — with a focus on clean, maintainable code.
- Architecture & Direction: Shape the technical direction of our frontend stack, drive component reuse and consistency, and help evolve the architecture as the product grows.
- End-to-End Ownership: Take features from design through production and beyond — including monitoring, troubleshooting, and iterative improvement.
- Quality First: Contribute to code reviews, and help raise the bar for engineering quality, performance, and accessibility across the team.
- Mentorship: Coach more junior engineers, share knowledge, and lift the overall skill level of the frontend team.
- Collaboration: Work closely with product, design, and backend engineers to translate merchant needs into solid, user-friendly solutions.
Requirements
- Experience: 10+ years of software development experience, with a strong frontend focus in recent years.
- Core Stack: Deep expertise in React, TypeScript, JavaScript, HTML, and CSS.
- Scale: Experience building scalable frontend applications used by many customers in production.
- Architecture: Strong understanding of modern frontend architecture — component design, state management, build tooling, performance, and testing.
- Ownership: Comfortable digging into documentation, finding answers, and taking ownership of your work.
- Problem Solver: You enjoy developing software and solving hard problems with simple solutions.
- Language: Proficient in written and spoken English (work is done in English).
Nice to have
- Experience in the financial industry, payments, or e-commerce.
- Experience designing and maintaining a shared component library or design system.
- Strong eye for accessibility (WCAG) and frontend performance.
- Familiarity with modern testing tools (Jest, Vitest, Playwright, Cypress).
- Exposure to Node.js / BFF patterns or related backend integration work.
How we work
Agile Scrum: daily standups, bi-weekly planning, regular demos, technology review meetings, and monthly retrospectives. We're committed to improving our documentation and stay flexible on workflow suggestions, while actively supporting technical improvement initiatives.
Why join us?
- A competitive compensation package aligned with seniority and experience.
- Hybrid working model — 50% in our Hoofddorp office, the rest remote, supporting a healthy work–life balance.
- Deep, hands-on exposure to PaymentIQ, a leading payment orchestration platform.
- Full access to a leading AI tooling stack — we invest in it because it makes our engineers better.
- Real ownership of meaningful work with production impact across hundreds of merchants and 300+ PSPs.
- A collaborative culture that values expertise, accountability, and getting things done.
Hiring Process
- First interview (30 minutes)
- Technical interview with the team (1–1.5 hours)
- Final interview with the team (1 hour)
- A coding task is part of the process.
