Job description

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Senior Backend Engineer, Integrations based in Germany.

Join a fast-growing technology environment and help build and scale the backend infrastructure powering a leading vacation rental management platform used by property managers worldwide. In this role, you will join the Core Engineering team, responsible for developing and maintaining critical integrations with major Online Travel Agencies (OTAs). You will design and operate high-performance backend services, modernize existing architecture, and improve connectivity across complex third-party APIs. You will play a key role in evolving a monolithic architecture toward scalable, service-oriented systems while shaping the technical direction of the platform. You will also help make backend capabilities accessible to AI agents through well-designed APIs and leverage modern AI coding tools to accelerate development. This is an opportunity to combine technical leadership, architectural ownership, and hands-on engineering in a fully remote, international environment.

Accountabilities:

• Design, develop, deploy, and maintain robust backend services using PHP and Go, ensuring scalability, reliability, and high performance.
• Lead the extraction of services from an existing monolithic architecture by defining clear service boundaries, ownership models, and pragmatic migration strategies.
• Collaborate closely with Product Managers and cross-functional stakeholders to shape technical priorities and ensure backend solutions deliver meaningful business value.
• Design and implement high-quality APIs that enable AI agents and automated workflows to interact reliably with guest-facing product capabilities.
• Optimize application performance, including page speed, response times, latency, and overall system reliability, working closely with frontend engineering teams.
• Contribute to architectural decisions and help establish scalable engineering practices while balancing speed of delivery with long-term maintainability.
• Improve and evolve event-driven, service-oriented architectures using Domain-Driven Design principles.
• Integrate AI-assisted development tools into daily engineering workflows to improve productivity, code quality, and delivery speed.
• Monitor and operate high-traffic backend systems, ensuring seamless integrations with major third-party platforms and minimal disruption to customer workflows.
• Promote effective collaboration across Engineering, Product, and Design while contributing to technical excellence and continuous improvement.

Requirements:

• At least 6 years of professional experience as a Backend Engineer, with a strong foundation in software engineering and backend system design.
• Advanced proficiency in PHP and/or Go (Golang), with the willingness and ability to work across both technologies.
• Proven experience designing, developing, and operating high-traffic, customer-facing applications and distributed systems.
• Demonstrated experience decomposing monolithic applications or extracting independent services, with a pragmatic understanding of architectural trade-offs.
• Strong API design experience, including REST, GraphQL, or similar technologies, with a focus on usability, versioning, scalability, and maintainability.
• Familiarity with event-driven architectures, service-oriented systems, and Domain-Driven Design (DDD) principles.
• Experience designing APIs for AI agents, LLM-powered applications, or automated clients is a strong advantage.
• Practical experience using AI-powered coding assistants such as Claude Code, Cursor, GitHub Copilot, or equivalent tools as part of everyday development.
• Experience working with cloud infrastructure and services; AWS experience is considered a plus.
• Familiarity with message queues and asynchronous processing technologies, such as AWS SQS, is an advantage.
• Strong problem-solving and analytical skills, with the ability to make sound technical decisions in complex environments.
• Excellent communication and collaboration skills, with the ability to work effectively with distributed, international teams and cross-functional stakeholders.
• A proactive mindset, strong sense of ownership, and ability to balance independent execution with collaborative decision-making.
• Must be physically based in Europe to ensure effective collaboration with colleagues and internal stakeholders.

Benefits:

• Competitive Compensation: Market-aligned salary based on the applicant's country of residence.
• 100% Remote Work: Complete flexibility to work from home, a coworking space, or another suitable location within your country of residence.
• Temporary International Remote Work: Possibility to work temporarily from another country with prior approval from your team lead, in accordance with the remote working policy.
• Equity and Stock Options: Access to company stock options, allowing employees to share in the organization's long‑term growth and success.
• Annual Team Offsites: Opportunities to meet colleagues in person once a year, strengthen team relationships, align on strategy, and collaborate in new locations.
• Professional Development: Significant learning opportunities, career advancement prospects, and exposure to complex technical challenges within a rapidly growing business.
• Annual Paid Leave: Paid vacation entitlement aligned with local employment regulations and country‑specific contractual arrangements.
• Country‑Specific Benefits: Access to additional benefits depending on your country of residence, including health insurance and pension contributions where applicable.
• International Team Culture: Opportunity to collaborate with a diverse, globally distributed team spanning more than 40 countries.
• Values‑Driven Leadership: A collaborative working environment where company values guide everyday decisions, leadership practices, and long‑term strategy.
• AI‑Powered Engineering Environment: Access to advanced AI development tools, including a Claude Team Premium subscription, to support efficient and innovative software development.
