You will build and maintain integration logic on top of our service-based architecture, evolve patterns, and keep systems scalable and observable. A proactive, autonomous mindset is essential in this fast-growing group.

• 3+ years of experience as a backend developer, with PHP expertise (thin-framework or framework-less REST APIs).
• Fluent in English – Additional languages are a plus!
• Public facing communication skills, especially in dealing directly with business partners and sales agents.
• Hands-on experience with similar positions, mediating between tech and non-tech.

• Prioritize and gracefully handle the pressure that may come from the integrating part or from sales.
• Build and maintain custom integration logic on top of our existing systems.
• Help evolve our service-based architecture by proposing patterns, improvements and shared standards.
• Keep our systems scalable, observable and maintainable as we grow.
• Join a small, open and supportive team that moves fast, with a brief daily stand-up and mostly asynchronous work.
• Flag blockers, risks and progress early. We value transparency over perfection.
• Bring curiosity about the business, not just the code. Understanding why something matters to the customer or to operations makes you a better engineer here.

Job description

At Suntransfers, we make airport transfers seamless for millions of travelers worldwide every year. We know that getting to and from a holiday destination can be stressful — especially when traveling through an overseas airport or port. That’s why we exist: to ensure our customers reach their destination effortlessly and with a smile on their face.

We provide a stress-free, enjoyable, and affordable experience, allowing customers to start and finish their trip in style — always supported by the best customer service.

Today we're part of a larger group alongside CMAC, specialists in flight disruption services across Europe, and CDG, who operate their own fleet of vehicles. Together, we're building the future of travel experiences, blending technology, flexibility, and operational excellence.

Why this role matters

Behind every successful airport transfer, there's a robust ecosystem of internal tools, partner integrations, real-time data flows, and reliable APIs. As we scale and modernize our platform, we need an Integrations Engineer to help us manage everything around integrations with partners and suppliers.

You'll join an existing development team and take real ownership of the integration process: being the main point of contact with future partners and suppliers, from the initial integration request to the final rollout in production. You will understand their needs, how they are fulfilled by our systems, and coordinate the whole process. You'll team up with our sales agents all the way for each case.

You will handle the integration process, so it is expected for you to devise, propose, and develop any improvements you might see fit for that.

This is not a role where you wait for someone to tell you what to do. You'll work autonomously, bring your own ideas, and flag issues before they become problems. You are part of a team, and when something goes wrong in production, we don't look for someone to blame. We look at what failed in the system and how to fix it together.

What you will do

Integration Process Management

• Own integrations end to end, from request to final certification, ensuring both technical quality and real business value.
• Build strong relationships with partners and suppliers, keeping them informed and engaged throughout.
• Work closely with development and sales colleagues, sharing knowledge and supporting each other.
• Be able to prioritize and gracefully handle the pressure that may come from the integrating part or from sales.

Integration Development & Platform Evolution

• Build and maintain custom integration logic on top of our existing systems.
• Help evolve our service-based architecture by proposing patterns, improvements and shared standards.
• Keep our systems scalable, observable and maintainable as we grow.
• Join a small, open and supportive team that moves fast, with a brief daily stand-up and mostly asynchronous work.
• Flag blockers, risks and progress early. We value transparency over perfection.
• Bring curiosity about the business, not just the code. Understanding why something matters to the customer or to operations makes you a better engineer here
