Job summary

Suntransfers in Barcelona, Spain, is seeking an Integrations Engineer to own integrations end-to-end with partners and suppliers. You will coordinate requests, certifications, and production rollouts, working with sales and development teams to deliver real business value.

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.

Qualifications

• 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 previous exposure to the travel, transport, or e-commerce sector.

Responsibilities

• 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.
• 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.
