Frontend Software Engineer

Job description

Keboola is a versatile data operating system that enables companies to automate business actions using data and produce value. It is also flexible enough to be deployed in big enterprise stacks, thereby helping data teams work faster and smarter. Keboola lowers the barrier to entry for aspiring data teams and helps increase the productivity of data teams by reducing the complexity of the data stack, design, operation and maintenance. This leads to a better focus on the actual business value.

Keboola’s success is built by innovation, and our team spread across offices in Prague, Vancouver, Chicago, greater Europe, and beyond. We believe that when people have a mission and a voice, their well-being and performance is better. Our environment stands for no BS and grants our people the ability to interact freely across teams connected by a passion for a culture of continuous learning while encompassing care, love, and respect.

We are looking for an experienced Frontend Engineer (senior or mid-senior level) who wants to make an impact in a growing SaaS-based company. You will work within a small team, taking care of several UI applications and improving their speed, usability, and experience—all of that while cooperating with our design team.

You will work closely with our backend engineers, discussing our services and providing feedback, so that the UIs will consume data from APIs in the most efficient way and structure. Our design team will provide you feedback for existing applications and propose possible improvements (in terms of UI/UX), and you will implement them.

The ideal candidate will be be based in Prague with the ability to work hybrid (2-3 times a week in the office). The successful candidate must speak English and Czech or Slovak with the ability to work for an EU-based company.

What you’ll do

• Contribute to the existing UI applications (we are using React) and implement new ones when needed.
• Take part in the design, implementation, and architecture of new and existing services (e.g., if the backend team needs to change the API you work with, they will consult you about it) as well as the whole platform.
• Undertake code reviews for members of your team.
• Be actively involved in designing technical features (participate in design docs).
• Share knowledge and experience in new areas and technologies with people outside of your team.
• Work closely with the design team on our new Design System/Component Library and adoption of the library into existing applications
• Maintain “hosting” for UI applications—our CDN.

Tech Stack

• The foundation of our stack is React 18.3+ with TypeScript 5.7+

• To have a stable ecosystem we use Node 22 LTS - latest LTS for performance and modern features

• And also we use Turborepo, so we can manage/release more applications from one place

• For fast development we use Rspack with SWC - lightning-fast builds (3x faster than Webpack)

• For our smaller apps we use Vite

• We manage dependencies with Yarn 4.5.3 with workspaces - dependency management that doesn’t fight you

• For data fetching we use TanStack Query

• For client state we use Zustand

• We’re migrating from Flux/Immutable.js (you’ll help with this!)

• We develop components in isolation with Storybook

• We test with Jest + React Testing Library

• We run E2E tests with Playwright - E2E tests that run in production environments

• We maintain code quality with ESLint + Prettier

• We built our own @keboola/design system - our own component library

• We style with TailwindCSS - utility-first styling that’s actually maintainable

• We use Radix UI to have accessible primitives that work everywhere

What we look for, and the required skills:

• Five years of experience as a developer with over three years of experience as a Frontend Engineer building UI applications in React or similar frameworks.
• A passion for engineering and problem-solving.
• Knowledge of standard technologies used to build and provision UI (JavaScript, TypeScript, CSS, etc.—the basic elements).
• Knowledge of UNIX-based systems, coding, and scripting (mainly when Continuous Integration is involved).
• Awareness of micro-service architecture (so you will know how/why UI communicates with each of the services).
• Experience with UI applications monitoring (TTFB, FCP, LCP) and error reporting
• Experience with deployment of UI applications
• A technical understanding of concepts and how they fit into the “big picture.”

We also require some basic soft skills.

• Orientation toward results and driving a task from the beginning to the end if needed; a willingness to take ownership.
• Patience and attention to detail.
• Being a bug hunter, but knowing what is enough.
• Readiness to ask for help.
• Team player, not an independent worker. (We work as a team.)
• Self-organization and self-discipline.

A little bit more about the opportunity

• Autonomy within your position. We are focused on outcomes, not micromanaging everything that you do. We love free company movement.
• Work with great brands both locally and worldwide. Ask us who we were working with!
• The opportunity to create the job you want that fits in with the life you want. We know there is life outside of work, and think fulfillment is achieved when all areas of your life fit together.
• We strive to push people for career development. There are many traits for a component team person - core Keboola platform tech team,  consulting and other “departments” are always open for internal hires!

You can look forward to the following benefits

• Competitive compensation.
• Generous paid vacation time.  And we mean generous.
• Cool new offices in the heart of Holesovice in Prague. You need to be 2-3 times a week in the office.
• No set office hours and flexibility.

Keboola’s Core Values

• Care, love and respect
• No BS
• Get your stuff done and do a bit more
• Create and innovate
• Learn!
• One team
