Frontend Developer Opportunity

Looking for a place where your ideas are heard, your code is shipped, and learning never stops? Do you want to learn by building software that powers real-world events — from festivals to film shoots in 70+ countries?

About us

Rentman is a B2B SaaS scaleup building smart, powerful resource management software for event and production teams. Our users plan everything from small shoots to massive festivals in 70+ countries — and they all rely on Rentman to keep their gear, people, and timing perfectly in sync.

Mission Of This Role

As a Frontend Developer at Rentman, you’ll shape the interfaces that thousands of event professionals rely on every day — from festivals to film sets. You’ll design performant, scalable, and reusable Angular components, bring UX ideas to life, and take ownership of frontend architecture that supports a powerful, real-time SaaS platform.

What Are You Going To Do?

• Design, build, and maintain high-performing, reusable Angular components and modern UIs across the product.
• Manage application state effectively for complex UIs and data-heavy workflows
• Collaborate with backend developers, designers, and QA to deliver features from concept to release
• Take technical ownership of some features — shaping implementation, anticipating edge cases, and ensuring quality
• Drive UX improvements with the Design team and help raise the bar for usability and accessibility
• Contribute to architectural decisions, tech alignment meetings, and frontend tooling improvements
• Pair with junior developers to share knowledge and support onboarding
• Having fun doing all of the above

Our Stack

Rentman is a modern cloud-based web-application relied on daily by our users to administer movement of equipment and access data on the go.

Front-End

• Current version of Angular as our main frontend framework, using Typescript
• A mobile app developed with Ionic and Capacitor built using Angular components
• Compilation and bundling done by Webpack
• Websockets (NodeJS and SocketIO) to sync data between clients
• We work based on "Continuous integration" so our systems can separately run on different version

Back-end

• From a back-end perspective, Rentman consists of our internal API, a public API and a set of microservices. The internal API is quite intense on complex database calculations. Modern version of PHP and MySQL, used in our internal API. Modern versions of Laravel, used by some of the microservices. Our backend is deployed on AWS

Testing Approach

• Automated unit testing on every pull request
• Automated E2E tests with Ghost Inspector, running weekly and on-demand
• Automated mobile app tests with Appium and Webdriverio
• Weekly manual regression testing
• Manual testing on-demand

Methodology

We follow Scrum with two-week sprints and weekly releases. Our four self-organising dev teams each focus on their own product stream and consist of a product owner and 4 to 6 frontend or backend developers, one of them has the role of scrum master. A dedicated QA team supports testing and manages regression tests and releases. During a weekly 'Tech Alignment' meeting, developers together with the CTO discuss technology, address technical debt and decide on our technical roadmap. 20% sprint capacity can be used for initiatives on the technical roadmap.
