At Blockbax we’re setting a new standard for data-driven operations, turning millions of sensor readings and control signals into real customer value. Our team is a mix of frontend, backend, cloud, and data engineers who enjoy solving complex engineering challenges and turn them into intuitive, high-impact software that users love.
The frontend is where all of that data becomes understandable. We build a React and TypeScript web application and a React Native mobile app that let operators monitor thousands of assets, spot anomalies, and act on them in real time. We’re looking for a Frontend Engineer to help us raise the bar on how that experience looks, feels, and performs.
If you strive for engineering excellence, care deeply about the details users notice, and want to build interfaces that people rely on every day, Blockbax is for you.
What you'll do
- Build and evolve our web application in React and TypeScript, from reusable components to complete product features.
- Develop our mobile app in React Native and TypeScript, keeping it fast and reliable on both iOS and Android.
- Make complex data understandable, designing charts, maps, and dashboards that stay responsive with high-volume, real-time sensor data.
- Own our frontend architecture, including state management, our component library, build tooling, and performance.
- Work closely with design and backend engineers, shaping APIs and interaction patterns together instead of receiving them finished.
- Drive best practices around accessibility, testing, security, and maintainable code.
- Automate everything that should not require human intervention, reducing operational load and the risk of errors.
- Help shape the culture and methodology of a rapidly growing company.
What we’re looking for
You’re an experienced engineer who cares about both the craft of the interface and the engineering behind it, with a strong sense of ownership and pragmatism.
- 5+ years of professional experience building and maintaining production web applications.
- Strong React and TypeScript skills, with a solid grasp of modern frontend fundamentals such as state management, rendering behaviour, and browser performance.
- Experience with data-intensive interfaces, for example real-time updates, large datasets, data visualization, or mapping.
- Comfortable turning designs into pixel-accurate, accessible, and responsive interfaces, and confident giving design feedback along the way.
- Familiarity with modern frontend tooling and workflows, including bundlers, automated testing, and CI/CD pipelines.
- A Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience and/or relevant certifications.
- Strong communication skills and a collaborative mindset. You enjoy enabling other engineers and raising the bar across teams.
- Bonus: Experience with React Native, or with charting and geospatial libraries.
What we offer you
- Competitive salary and benefits.
- Employee participation plan with company shares.
- A great office in the city center of Rotterdam (2-minute walk from Central Station) and flexible working arrangements, with the option to work up to 50% of the time from home.
- Opportunities for professional growth and learning.
- Experience a culture of respect, impact, and fun like no other!
- The chance to work on cutting-edge technology that makes a difference.
