Senior Software Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer based in Spain.

As a Senior Software Engineer, you’ll build the APIs, integrations, and infrastructure that connect a modern hospitality platform with a broad ecosystem of technology partners.

Your work will directly influence the reliability, scalability, and extensibility of products used by businesses around the world.

You’ll develop primarily in Python while applying strong software engineering principles across distributed systems, databases, APIs, and cloud infrastructure.

You’ll design resilient event-driven workflows that protect data integrity and allow systems to recover gracefully from partner failures.

The role combines hands-on development with architectural decision-making, technical discovery, and close collaboration with both technical and non-technical stakeholders.

You’ll join a pragmatic, globally distributed engineering environment that values ownership, defensive design, observability, and continuous improvement.

This is an opportunity to solve complex integration challenges while helping shape reliable technology at significant scale.

Accountabilities

• Contribute daily as a senior member of an agile engineering team, following strong software development practices and contributing to the shared codebase.
• Develop, maintain, and improve production applications primarily using Python.
• Design and deliver reliable APIs and integration capabilities that enable partners to connect with the wider product ecosystem at scale.
• Build resilient event-driven workflows incorporating idempotency, retries, dead-letter handling, reconciliation, and graceful degradation.
• Design software that remains reliable when interacting with external systems that may have limited control, availability, or predictability.
• Apply strong engineering practices to produce clean, maintainable, well-tested, well-documented, and efficient code.
• Participate in technical discussions covering complex requirements, architecture, design patterns, and implementation approaches with both technical and non-technical stakeholders.
• Collaborate directly with customers and technology partners to understand challenges and identify effective technical solutions.
• Research and evaluate emerging technologies, libraries, tools, and techniques to determine their suitability for the platform.
• Contribute to architectural decisions and the continuous improvement of development and operational practices.
• Drive strong API design and developer experience so that partners can integrate efficiently and reliably.
• Support knowledge sharing, code reviews, and a collaborative environment where engineering skills and capabilities can grow.
• Own aspects of cloud-native delivery and operations, including deployment, monitoring, troubleshooting, and production incident response.

Requirements

• 5+ years of professional software engineering experience building, shipping, and operating production applications.
• Strong proficiency in at least one production programming language such as Python, Java, TypeScript, or PHP, with the ability to work effectively across a broader technology stack.
• Strong understanding of relational data modeling, PostgreSQL, caching, API design, distributed systems, and asynchronous or event-driven architectures.
• Solid software engineering fundamentals covering maintainable architecture, design patterns, automated testing, debugging, performance optimization, security, and operational reliability.
• Strong knowledge of REST APIs and modern API design best practices.
• Experience working in environments where high availability, scalability, security, automation, and observability are core engineering priorities.
• Demonstrated commitment to observability and data-driven engineering decisions through metrics, experiments, prototypes, and system insights.
• Strong knowledge of software engineering best practices and a passion for building reliable, developer-friendly APIs.
• Experience owning cloud-native application delivery and operations, including technologies such as Terraform, Docker, Kubernetes, Helm, Argo CD, AWS, CI/CD, and observability platforms.
• Experience participating in or leading production incident response and operational troubleshooting.
• Strong teamwork, organization, prioritization, and time-management skills.
• Excellent written and verbal communication skills, with business-level English proficiency.
• Comfortable collaborating effectively within a fully remote and globally distributed engineering organization.
• Strong sense of ownership and a pragmatic approach to solving complex technical problems.

Benefits

• Fully remote, remote-first working environment.
• Opportunity to work with an international, globally distributed team across numerous countries and time zones.
• Paid time off in accordance with local labor requirements.
• Monthly Wellness Fridays, providing an extended weekend each month.
• Fully paid parental leave.
• Home office stipend based on country of residence.
• Access to professional development courses through an internal learning platform.
• Opportunities for upskilling, manager training, knowledge sharing, and continued professional development.
• Exposure to modern cloud-native technologies and large-scale distributed systems.
• Opportunity to work on complex integrations connecting a broad ecosystem of technology partners.
• Inclusive, collaborative culture that values diverse perspectives and backgrounds.
• Meaningful technical ownership and opportunities to influence architecture, engineering practices, and product reliability.
