Integrations Engineer

About us
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

• Take end-to-end ownership of integration requests from submission until final certification. That is, covering all the technical parts, but also to make sure value is delivered in the end.
• Understand the needs of each partner/supplier and communicate properly towards a successful outcome. To keep them all engaged and informed.
• Be a team player. Understand and support your colleagues from development and sales, just as you share your knowledge and get support from them.
• Be able to prioritize and gracefully handle the pressure that may come from the integrating part or from sales.

Integration Code Development & Platform Evolution

• Build and maintain any special integration logic on top of our existing systems when needed.
• Contribute to the evolution of our service-based architecture, proposing patterns, identifying improvements, and helping establish shared standards across the development team.
• Help ensure our systems are scalable, observable, and maintainable as we grow.

Collaboration & Culture

• Work within a small development team that communicates openly in a safe space, moves fast, and helps each other. We run a brief daily and work asynchronously most of the rest of the time.
• Proactively communicate blockers, risks, and progress. We don't expect perfection; we expect transparency.
• 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.

Current Stack

• Backend: PHP, .NET
• Frontend: Next.js
• Infrastructure: K8s, AWS, Cloudflare.
• Data: MySQL, DynamoDB and Redis.
• Monitoring: New Relic, Grafana Stack.
• There are legacy projects that we want to move forward, so we’re progressively moving to a composable, scalable architecture, with continuous delivery and improved observability.

What we're looking for

• 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.
• A strong will to own your work end-to-end: to see things through, flag problems early, and take responsibility when things don't go as planned.
• Ambition to improve and innovate the existing integration processes.

It would be a plus if you also have

• Knowledge of .NET. Reading and navigating some .NET codebases are a real part of this role.
• Familiarity with observability tooling (Grafana, or similar).
• Previous exposure to the travel, transport, or e-commerce sector.

What We Offer

• Office located in Barcelona, Spain.
• Flexible Work Setup. Hybrid work model with home and office days.

• Work from Anywhere. Enjoy the flexibility to work remotely from anywhere in the world for up to 4 weeks a year.
