<html><head></head><body><div class="job_listing-description job-overview col-md-10 col-sm-12">
 <h2 class="widget-title widget-title--job_listing-top job-overview-title">Overview</h2>
 <h2 id="job-description-title">Description</h2>
<div>
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 capable of creating and maintaining 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 (such as cross-selling and multi-booking), and a dependent-booking management 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 &amp; Transforming
Our checkout widget is a SPA build upon Svelte 5 (migrated from v4), 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 take should be taken with the full intent to be responsible for it.
What does it mean?
<ul>
<li>You are the owner of the delivery; you can push it, tweak it, and ask for questions!</li>
<li>You know when to be pedantic and take safe steps, and when to take action</li>
<li>You can deliver 🙂</li>
</ul>
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; we use them to improve 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 always be decision-making before a package is included in 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
<ul>
<li>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.</li>
<li>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.</li>
<li>You’re a Problem Deconstructor: You are a highly autonomous operator. You can analyse 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.</li>
</ul>
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.
</div>
<h2 id="job-benefits-title">Benefits</h2>
<div>
What can we offer?
<ul>
<li>We are fairly informal about working hours. We want to make sure you like your job and wanna go an extra mile for us.</li>
<li>Unlimited paid holiday days.</li>
<li>Start-up working environment.</li>
<li>WFH or work remotely.</li>
<li>Team buildings and company remote office. Sounds boring? The whole team met in Spain, South Africa, Italy, Portugal, France and this year also in Greece.</li>
<li>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? 🙂</li>
<li>Young and passionate team – the ‘Ventrata family”</li>
<li>Hardware/ remote setup package.</li>
<li>Competitive salary and regular salary revaluation.</li>
<li>Christmas bonuses.</li>
</ul>

Overview
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 capable of creating and maintaining 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 (such as cross-selling and multi-booking), and a dependent-booking management 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 &amp; Transforming
Our checkout widget is a SPA build upon Svelte 5 (migrated from v4), 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 take should be taken with the full intent to be responsible for it.
What does it mean?
You are the owner of the delivery; you can push it, tweak it, and 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; we use them to improve 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 always be decision-making before a package is included in 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 analyse 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.
Benefits
What can we offer?
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, France and this year also in Greece.
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 – the ‘Ventrata family”
Hardware/ remote setup package.
Competitive salary and regular salary revaluation.
Christmas bonuses.
Did we catch your eye or maybe also your heart and do you want to become part of the Ventrata team? Send us your CV and join us!

About Ventrata
Ventrata is an enterprise ticketing platform designed for high-volume attractions, museums, observatory towers, sightseeing tours, and activity operators. Our all-in-one solution powers online, in-person, and third-party sales, and provides robust functionality for resource management, hardware integrations, and 24/7 live support.
Leading brands across diverse verticals trust Ventrata’s solutions, and our focus on building long-term connections is key to mutual success. Since 2016, we have worked with many City Sightseeing operations and have teamed up with notable companies like Big Bus Tours and Historic Tours of America. Our recent partnerships, including those with English Heritage, Paradoxon, the Empire State Building, Thames Clippers, and many others established over the past two years, show strong potential to evolve into enduring, long-term relationships. These examples represent just a few of our many collaborations driving the innovation behind the 21 million tickets we sold in 2023 — a 60% increase from the previous year.
What truly sets us apart is our independence — we’ve been profitable since 2018, with no reliance on venture capital. This financial stability allows us to innovate and grow on our own terms.
We value collaboration and freedom ensuring that every team member has the space to take ownership, be heard, and drive real impact.


Requirements
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.

Senior Frontend Developer (Svelte Specialist)

Hello, my name is Angel Nikolov and I am the founder of <a href="https://remotefrontendjobs.com">https://remotefrontendjobs.com</a> and <a href="https://remotebackendjobs.com">https://remotebackendjobs.com</a>.
 
 
 I recently noticed some of your advertisements on similar job boards like weworkremotely, jobsinjs and wondered if you’d be interested into featuring an ad on remote frontend and backend focused job boards.
 
 In fact, since both my sites are aggregating multiple different sources some of your advertisements are already listed and you can see some of them here - <a href="https://remotefrontendjobs.com/ckz88kvix65763ubw6yzkiegl?ref=marketing">Senior Software Developer (node.js)</a>, <a href="https://remotefrontendjobs.com/ckzvojuu00367s2bw0kwl0gar?ref=marketing">Senior Software Developer (React.js)</a>.
 
 
 Featuring a job now will guarantee top visibility and engagement and will most definitely bring some people your way.
 
 I already have my first customer and for 20 days their advertisement was seen more than a thousand times and was engaged with about 170 times.
 
 
 In case that you want to feature some of your ads for a small early-bird fee, the only thing I will need from you is to let me know which ones and which job board you'd want them on or just send me the job details by email. 
 Let me know if like the idea,
 
 Angel Nikolov

Hi, it's Angel Nikolov again!
	 
	I just wanted to follow up on my last email and ask you if you had time to review the the idea for featuring a job on <a href="https://remotefrontendjobs.com?ref=marketing">https://remotefrontendjobs.com</a> or <a href="https://remotebackendjobs.com?ref=marketing">https://remotebackendjobs.com</a>.
	 
	 
	I would appreciate any kind of feedback!
	 
 Thanks again!
