Job description
Imagine standing at the top of the Empire State Building, taking in the breathtaking view. From the online booking to the seamless entry, every part of your ticketing experience was designed and supported by Ventrata. An industry-leading SaaS platform that helps attractions, tours, and activities to create memorable experiences.
Backed by a passionate team, headquartered in London and with offices in Brno, Lisbon, and remote teams worldwide, we’re expanding rapidly across multiple markets and verticals. Our mission is to help businesses of all sizes scale and grow while preserving their unique identity and spirit.
Be a part of something extraordinary, where your ideas and contributions truly matter. Let’s shape the future of travel together.
Are you a frontend craftsman with an ability to create and maintain complex projects? Are you interested in cutting-edge technology? Do you see an existing, high-quality app not just for what it is, but for what it could become? If the challenge of transforming a modern application with a total redesign and Svelte 5 excites you, we need to talk.
The Challenge: A Ground-Up Redesign on a New Foundation
This isn’t about tweaking a simple app. Our core product is a powerful, configuration-driven checkout widget with multiple display modes, complex booking flows (like cross-sell and multibooking), and a dependent booking managing module. It’s a mature, high-quality application, and now it’s ready for its next evolution.
Our mission is to execute a total redesign. This is more than a facelift; it’s a fundamental reimagining of our user flows, component library, and design system, all built upon a modern Svelte 5 foundation.
What You’ll Be Building & Transforming
Our checkout widget is a SPA build upon Svelte 4, Vite, Typescript, Tailwind, Vitest and Cypress.
Your responsibility will be foundational migrations (upgrading Vite, Tailwind, etc.), giving you a unique opportunity to learn the codebase’s intricacies. With that foundation in place, you will participate on translating a new, comprehensive Figma design with a great focus on project maintainability and code clarity.
As our Senior Frontend Engineer, you will be the primary force for this transformation, working alongside our Tech Lead to build the future of our product.
What else?
We are looking for out-of-the-box thinking. Any action you do should be taken with full intent to be responsible for it.
What does it mean?
- You are the owner of the delivery, you can push it, tweak it, ask for questions!
- You know when to be pedantic and take safe steps and when to take action
- You can deliver :)
What about AI?
We are heavily integrating AI into our process, using tools like Claude Code for code generation or Gemini CLI for experiments.
This doesn’t mean we delegate our work to agent systems, but we use them to leverage the delivery. They are meant to augment our creativity and accelerate development. We don’t expect autonomous deliveries without your involvement.
Other packages?
Our philosophy is “lean by design,” and you’ll be a key guardian of our codebase’s quality as we transform it. We are building a product with specific needs. There will be always decision-making before package inclusion into the codebase. Size and complexity are the kings and this requires deep technical expertise. You need to know how to develop components and libraries.
What about test coverage?
We have top-league QA with an excellent E2E suite. You will be required to cover your features with component tests and unit tests. This is not your regular ‘ship it and see if it works.’
We’re talking about uncompromising quality. Cypress and Vitest are your friends.
What ‘Senior’ Means to Us
You’re a Master Builder: You’ve been in the trenches with complex SPAs. You can look at a solid, existing system and see how to make it exceptional. You don’t just talk about patterns; you implement them effectively to create clean, maintainable, and performant code.
You’re a Product-Minded Engineer: You don’t just build what’s on the ticket; you seek to understand the “why.” You can dive into complex business domains (like travel ticketing) and translate that logic into an intuitive, seamless user experience.
You’re a Problem Deconstructor: You are a highly autonomous operator. You can analyze a complex system, plan a multi-step transformation, and execute it with precision without needing constant oversight. A powerful sense of ownership is your core trait.
You’re a Tech Enthusiast: The idea of leveraging AI tools in your daily workflow excites you. You understand CI/CD principles (we use GitHub Actions) and have a solid grasp of API design. Any backend experience is a plus.
Expert knowledge of modern JavaScript (ESNext) and TypeScript.
Proven experience building and maintaining complex, large-scale Single Page Applications (SPAs).
Experience with large-scale refactoring and evolving a mature codebase.
Demonstrated ability to work with intricate business rules and user flows.
Deep professional experience with Svelte is a significant advantage. Alternatively, expert-level experience in React or Vue with a demonstrable passion for mastering Svelte.
A pragmatic approach to problem-solving and a love for the craft of frontend development.
Intermediate English proficiency.
Nice-to-have: Backend development experience.
Also, please note that the team is mostly based in the Czech Republic, so we would prefer a candidate from the same time zone.
- We are fairly informal about working hours. We want to make sure you like your job and wanna go an extra mile for us.
- Unlimited paid holiday days.
- Start-up working environment.
- WFH or work remotely.
- Team buildings and company remote office. Sounds boring? The whole team met in Spain, South Africa, Italy, Portugal, and France. We also enjoy a spontaneous beer after work or any sports activity.
- Office in Brno and Lisbon. We have two office locations: the core team is located in Brno and we have one newly opened office in Lisbon. How does working for a month from Lisbon sound? :)
- Young and passionate team.
- Refreshments and delicious coffee in the office area.
- Hardware/ remote setup package.
- Competitive salary and regular salary revaluation.
- Bonuses based on company performance.
