About KLAR

Let’s start with the basics!

We have an exciting and ambitious roadmap to bring more features to our products so that we can better serve our users. We have served more than 2 million users since our launch in 2019!

We are also proud to have been certified in 2023 as a “Great Place to Work” in Mexico - we’ve worked hard to make that happen and will continue to make bigger strides in the future! Sound like a place you’d like to be?

As a Senior Web Engineer at Klar, you’ll be part of a fast-moving, product-driven team shaping the future of digital finance in Mexico. You’ll play a key role in crafting fast, responsive and reliable web experiences using React and modern web technologies.

Your days will include collaborating with team members, back-end engineers, and product managers to deliver features that improve internal tools used by hundreds of users that give support to all our customers.

You’ll develop new features for our back office applications, author and review pull requests, and be part of shaping engineering decisions that have real impact on millions of users.

• Optimize applications for speed, scalability, and security.
• Proactively identify areas of improvement in the frontend architecture and help drive technical initiatives.

Requirements

• 5+ years of professional experience building web applications in modern JavaScript/TypeScript.
• Deep experience with React.js and modern features (hooks, context, portals, Suspense).
• Strong understanding of component design patterns and state management in React (e.g. Redux, Zustand, RTK).
• Experience with RESTful and GraphQL APIs.
• Familiarity with CI/CD workflows and frontend testing (Jest, React Testing Library, Cypress, etc.).
• Strong understanding of browser performance, web vitals, web accessibility (WCAG), and responsive design.
• Experience working in agile environments with cross-functional teams.
• Fluent English communication skills (written and verbal).

Benefits

• Competitive salary based on performance and experience
• Chance of earning Klar stock options
• 26 days of paid vacation per year
• Computer devices
• Wellhub subscription to offer mental and physical health
• Sponsored coaching and therapy sessions via Modern Health
• Access to Desana, a network of flexible workspaces around the world
• International work environment with amazing and highly skilled people
• A world class team that helps you evolve your skills in areas you're interested in

Klar is a safe place for everyone!

We trust our highly skilled and diverse team and we’re committed to creating a welcoming and inclusive environment for new talents to flourish.
