Our dream candidate

We are looking for a highly capable Full Stack Engineer who loves building great products just as much as writing great code. You'll fit right in if you:

• Drive the AI Future:
  You know how to work smarter, not just harder. You are expected to drive innovation, automating and optimising the whole flow with agentic tools, testing and incorporating cutting edge techniques. From writing and reviewing code to optimizing the broader software development lifecycle, you know how to make the best use of these tools to boost your efficiency and problem-solving capabilities.

• Own it end-to-end:
  You thrive in a collaborative environment and will always have the full support of your team, but you are also highly autonomous. You are fully capable of taking a feature from its initial concept all the way through to deployment.

• Have a product-oriented mindset:
  You don't just build what you're told; you actively shape it. You don't hesitate to make product decisions on the fly, leaning on your familiarity with UX standards to nail down design details without needing a pixel-perfect mockup for every single screen.

• Cross boundaries to collaborate:
  You know that the best features start with a deep understanding of the user. You aren't afraid to step outside the engineering bubble and partner directly with Product Managers and Customer Support to dig into the "why," ask the right questions, and refine the requirements.

• Are truly full-stack:
  You feel equally at home in the back-end and the front-end. Whether you are architecting robust, scalable APIs or crafting smooth, responsive user interfaces for our web apps, you have the skills to make it happen.

Your role

• You act as a true owner for your features, taking full accountability from initial discovery through to final delivery and beyond.

• You are deeply involved in the design and exploration stages, leveraging AI-powered tools to accelerate prototyping, analyze user needs, and validate technical feasibility early in the process.

• You will leverage cutting-edge techniques and interact with AI tools at all stages of the software development lifecycle.

• You are a member of an agile team and work together with your colleagues to deliver new software increments.

• You are led, supported and guided by an experienced Engineering Manager assigned to your team.

• You partner with product managers and designers to co-create innovative solutions, ensuring that every technical decision is rooted in a deep understanding of the product vision and user experience.

• You will build new scalable services as well as improve existing systems.

• You will be involved in optimizing our processes, introducing improvements and new tools.

Your mission

Your mission is to be a core contributor in building and scaling bookingkit as the AI-powered Attractions Success Platform, orchestrating the future where every European attraction can thrive. You will leverage modern AI and cloud technologies to automate routine operational tasks, making business easy and fun for our vendors. Building on bookingkit's position as the market leader for infrastructure technology, you will be instrumental in designing the next generation of scalable services, APIs and state-of-the UI. Your work will set the technical foundation for all our innovations, driving our B2B2C SaaS platform and influencing industry standards.

Responsibilities

• Contribute hands-on to product design, user experience (UX) flows, and rapid prototyping to validate solutions early.

• Build and launch scalable, production-ready software.

• Collaborate with DevOps & QA engineers, as well as product managers during product exploration to give context on feasibility.

• Contribute to the product, software architecture, infrastructure, tech stack, as well as the user experience.
