Senior Frontend Engineer

You know the moment.

When you design a component API and realize that every decision – props, defaults, composition, accessibility, testing – will either help or slow down dozens of engineers for months to come.

That’s frontend engineering at scale. And that’s exactly the kind of responsibility you’ll take on in the Design System team at e-conomic.

Right now, we’re looking for a Senior Frontend Engineer to help shape the shared UI foundation that 13 product teams rely on every single day.

Diving into the role

At e-conomic, the Design System is not a side project, but a shared foundation.

Our component library is something teams use daily. Our Figma library sets the standard for how UI is designed across the product. And the developer experience around it, from documentation, testing, pipelines to releases, determines whether the system truly scales.

As a Senior Frontend Engineer in the Design System team, you will help evolve TACO, our design system, by building and maintaining robust, accessible and well-tested UI components, while also shaping the surrounding architecture that makes adoption easy and sustainable.

This role sits right at the intersection of frontend engineering, design and platform thinking.
Your work might not always be flashy, but it will quietly influence everything else that is.

What you’ll work on

This is a senior role with real responsibility, and you can expect a typical week will include:

• Developing, maintaining and distributing shared UI components using React and TypeScript

• Taking architectural responsibility for parts of the frontend codebase, ensuring scalability and long-term maintainability

• Improving and maintaining the CI/CD pipeline, including GitHub Actions and release workflows

• Ensuring high quality through unit tests, e2e tests and accessibility best practices

• Collaborating closely with UI Designers to turn design intent into flexible, usable components

• Working directly with product teams to support adoption, answer questions and refine APIs based on real-world usage

• Reviewing pull requests with strong judgment by helping the organization strike the right balance between idealism and pragmatism

You’ll help lift the heavier frontend work, while also setting standards that others can rely on.

The Design System team

The Design System team is a cross-functional group of designers and engineers.

We operate as a service team, collaborating weekly – often daily – with product teams and UX designers across e-conomic. Internally, we work as one unit:

• The team owns the design system – not individuals

• Communication is informal and the hierarchy is flat

• Ownership and responsibility are taken, not given

• Initiative is essential

• Trust, confidence and psychological safety are foundational

We value people who are willing to share knowledge, discuss decisions openly and help others grow – technically and professionally.

Your 1st year of impact

This is how we envision success in this role to look like a year ahead of joining the team:

• You’ve helped improve the frontend codebase by reinforcing best practices and standards, resulting in fewer bugs and failing tests

• You’re a trusted voice in architectural discussions, both within the team and across the organization

• Product teams experience the Design System as something that enables speed and quality 

• You actively mentor others and contribute to raising the overall frontend maturity at e-conomic

Why this role could be something for you

• A dedicated Design System team with real autonomy and impact

• A large, mature product where design systems truly matter

• The chance to influence how frontend engineering is practiced across 13 teams

• Plenty of room to grow — technically, architecturally and as a mentor

• Colleagues who care deeply about quality, collaboration and doing things right

Your experience

We don’t expect you to tick every box, but we do expect seniority, depth and curiosity.

We imagine you’re a senior frontend engineer with experience from product engineering environments, where maintainability mattered as much as shipping.

You bring profound experience with:

• React and TypeScript

• Semantic HTML and modern CSS

• CI/CD pipelines and GitHub Actions

• Writing unit tests and e2e tests

• Accessibility and inclusive design principles

It’s a plus if you also have experience with:

• Building component libraries or design systems

• Design tokens and UI principles

• Usability and UX collaboration

• Tailwind CSS or other utility-first CSS frameworks

• Base UI and Tanstack React libraries
