Senior Frontend Engineer

🌍 About Payflows

At Payflows, we build software that helps large companies manage and automate their payment workflows. It’s not the flashiest part of a business—but it’s one of the most critical. When invoices, approvals, and payments slow down, the whole company feels it.

But we’re not here just to make a better workflow tool.

We believe the future of finance operations is not faster clicking: It’s no clicking at all 🫳🎤

Finance teams shouldn’t spend their days moving data between screens. Software should do the operational work, and humans should focus on what actually matters: decisions, approvals, and control.

That’s the future we’re building: an agent-driven finance platform where intelligent agents handle the repetitive tasks and users stay in control.

This is not a small incremental improvement.

It’s a shift from “tools people use” to systems that work on their behalf.

We started in 2022 with a small team and a rough first version of the product. Three years later, we’re working with major companies across France, the UK, and the US.

We moved fast. We shipped a lot. Not everything was built perfectly—but it helped us learn quickly, win real customers, and prove the problem is worth solving.

In 2024, investors trusted us with a $25M Series A.

Now we’re entering the next phase:

• Strengthening the foundations

• Scaling the product

• Building the system that will power this agent-driven future

Today, we’re about 35 people from many different countries, and we’re looking for a few amazing humans to join the next chapter. 🤗

🤝 What you’ll actually do

You’ll help build a product that real finance teams rely on every day—and shape the interface of an agent-driven system that automates critical financial operations.

For us, frontend engineering is not just about making things look good.

It’s about clarity, speed, and trust.

Our users move millions of euros through our platform. The interface must be:

• Simple

• Reliable

• Predictable

• Fast under pressure

In a typical week, you might:

• Build new product features in our web application.

• Design and implement reusable UI components.

• Improve performance and responsiveness of critical screens.

• Refactor early parts of the frontend to make them scalable.

• Work closely with product and backend to shape new workflows.

• Review code and help teammates improve.

• Build interfaces that let users review, approve, and control actions proposed by AI agents.

• Simplify complex finance processes into clear, confident user experiences.

Your time will be split between building new features and improving what already exists. Both matter.

You won’t just build screens.

You’ll help define the user experience of an agent-driven product, where automation does most of the work and humans stay in control.

You’ll work closely with product, backend, and customer-facing teams, and take ownership of parts of the interface as they grow in scale and complexity.

🛠 Our current tech reality

Our stack evolves based on real problems, not trends. We care more about good design and clarity than hype.

Our frontend is built with Vue.js and focuses on maintainability, performance, and predictable behavior.

• Core framework: Vue.js

• Language: TypeScript

• State management: Pinia

• Styling: SCSS

• Testing: Vitest + Playwright

• Build tools: Vite

• Architecture: modular frontend with shared components and clear data flows

Some parts of the system are clean and well-structured. Others were built quickly and need love. That’s the phase we’re in.

Over the next year, we’ll focus on:

• Turning complex financial workflows into simple, confident interfaces.

• Building a consistent, scalable design system.

• Improving performance across large, data-heavy screens.

• Increasing test coverage on critical flows.

• Cleaning up early code and reducing technical debt.

This is a moment where strong frontend engineers can have real architectural impact, not just implement tickets.

Who’s going to thrive with us ✨

You’ll probably feel comfortable here if:

• You like building products people actually use every day.

• You care about user experience as much as code quality.

• You are autonomous and take ownership of what you ship.

• You take initiative and lead by example.

• You’re curious and enjoy solving ambiguous problems.

• You’re pragmatic about trade-offs.

• You communicate with kindness and clarity.

This role is a great fit if you’re excited by the idea of:

• Designing interfaces for products powered by AI agents.

• Turning complex finance workflows into simple, clear user experiences.

• Working on a product that is early, ambitious, and evolving quickly.

• Having visible impact on architecture, performance, and UX.

What you’ll get from this role

• Real ownership over parts of the frontend.

• Direct impact on customers and product decisions.

• A small, high-trust team where your work is visible and meaningful 🤝

• A mix of feature work, system design, and technical improvements.

• Exposure to real scaling and production challenges.

• The chance to help build an agent-driven product from the inside.

We offer

• Competitive salary and equity.

• A new laptop 💻

• Flexible remote setup (we only ask you to be at the office 3 days each month).

• Work anywhere you want in Europe

• A high-autonomy environment where you have real ownership.

• Plenty of room to grow, take responsibility, and shape parts of the product.

• A team that values trust, clarity, and strong engineering culture.

This isn’t a huge corporate environment.

In exchange, you get autonomy, responsibility, and the chance to shape a product that’s still early in its story, and help build what finance operations will look like in the next decade 🚀
