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.

This is an exciting opportunity to be part of a small team within a larger engineering organization at a rapidly growing company.

While we support a distributed/remote work environment, we also have shared office spaces available in Brno and Lisbon. Candidates based in these locations — or anywhere across Europe — are encouraged to apply.

What will be your main responsibilities?

Requirements:
What does our ideal candidate look like?

The ideal candidate will be a Ruby wizard with solid experience of backend engineering. You will be a critical thinker with a high attention to detail. You will need to keep up with the fast pace of development and thrive in a startup environment. Do you have previous experience with a ticketing system? Even better …

And a few more requirements…

• Expert knowledge of Ruby on Rails.
• Expert knowledge of PostgreSQL.
• Advanced knowledge of Google CLoud.
• Intermediate English.
• Familiarity with Hotwire/Turbo/Stimulus
• Fast learner, who enjoys the dynamic scale-up working environment and is able to adapt to changes quickly and NO is not the answer you use (could be a tricky one during our team-buildings).


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.
