Role Description We are looking for a Senior Back-end Software Engineer who is first and foremost a problem solver. Someone who uses engineering as a toolbox to solve real customer and business problems. This role sits within our Trip Management System domain, the team that empowers our travel specialists to design extraordinary journeys at scale. We build the systems that transform destinations, itineraries, flights, hotels and pricing strategies into structured, sellable travel products. By enabling seamless product configuration and ensuring accuracy, flexibility, and scalability, we directly impact revenue, operational excellence, and the quality of the experiences we bring to our customers. Technology choices matter, but impact matters more. You’ll work across PHP, Node.js and modern AI tooling, choosing the right approach for each problem rather than being constrained by a single stack. Responsibilities - Product Configuration & Scalability - Build and evolve the systems that enable travel specialists to design, configure, and launch complex travel products at scale. - Transform destinations, itineraries, flights, hotels and services into structured, reliable, and sellable products. - Ensure flexibility and accuracy in product configuration while maintaining operational efficiency and long-term scalability. - Revenue, Pricing & Financial Integrity - Develop and improve capabilities that support smart departures, pricing strategies, booking breakdowns, payments, refunds, and wallet flows. - Safeguard financial correctness across the full product lifecycle, from configuration to checkout and post-booking operations. - Design systems that directly impact revenue performance and margin optimization. - Platform & Operational Excellence - Build internal platforms and tools that empower Product, Finance, and Operations teams to work autonomously and efficiently. - Increase reliability and reduce manual intervention in calendar management, flight configuration, and payment-related processes. - Continuously improve system robustness, reducing operational risk and scaling complexity without increasing overhead. - Product & Data-Oriented Engineering - Work closely with the whole team to refine problems before writing code. - Use data to validate assumptions, measure business impact, and continuously improve solutions. - Actively participate in shaping product decisions, not just implementing tickets. - Strong problem-solving mindset — you enjoy ambiguous problems and figuring out the best path forward. - Highly effective use of AI in daily work (coding, debugging, designing, analyzing, automating). - Product-oriented thinking: you care about why you’re building something, not just how. - Comfort working across multiple technologies and learning new ones as needed. - Solid knowledge of RESTful API design, development, and integration best practices. - Experience working with event-driven architectures (EDA) and message-based communication between services. - Familiarity with Domain-Driven Design (DDD) and clean architecture principles. - Working knowledge of CI/CD pipelines and version control best practices using Git (GitHub Actions or similar). - Strong emphasis on testing (unit, integration) and commitment to code quality, scalability, and maintainability. - Familiarity with observability practices — including logging, monitoring, and tracing — to ensure visibility and reliability across distributed services. - Excellent collaboration and communication skills to work effectively within cross-functional teams. Qualifications - Experience in APIs, integrations, and system design. - Familiarity with AI tools, LLMs, automation workflows. - Proven ability to design and integrate RESTful APIs with attention to performance and reliability. - Knowledge of testing practices (unit and integration) and a strong focus on code quality. - Familiarity with observability principles, including logging, monitoring, and tracing in distributed systems. Benefits - Competitive compensation package, in line with job responsibilities and experience. - Flexible compensation on transportation and food with Cobee also in our private health insurance. - Flexible working schedule, just make sure you meet your monthly goals! - 100% Remote working within Spain. - Permanent contract from the start. - Travel with Exoticca at reduced prices! - Referral bonus, if you bring people as talented as you can earn a very nice bonus! - Becoming part of a fun and motivated multicultural team at an agile and rapid growing organization where teamwork, drive, commitment, resilience and being customer-centric are the core values.
