Position overview

At Stay22, integrations with external travel suppliers (OTAs, retail providers, etc.) are core to our product's functionality and partner value. The Integrations squad is dedicated to maintaining these connections, ensuring data from third-party providers is cleanly ingested and readily available to power our products. We are looking for a Senior Full Stack Developer who thrives on the challenge of connecting complex systems and making data flow seamlessly. In this role, you will shape how we integrate and manage data from numerous third-party APIs, with a strong focus on backend development. Your expertise in Node.js and TypeScript will be crucial as you work closely with our Product Manager in a dynamic environment where priorities can shift with evolving partner requirements. Your work will be instrumental in handling large-scale data ingestion and normalization from external sources, ensuring our platform remains comprehensive, up-to-date, and highly reliable for users and partners.

Key responsibilities

• Own the end-to-end design, development, and rollout of new supplier integrations and data pipelines, demonstrating a high level of technical competency and leadership
• Utilize your deep knowledge of Node.js and TypeScript to build and maintain robust integration services and APIs, ensuring high performance and reliability in our data pipelines
• Integrate with third-party travel suppliers and partners via APIs, SFTP, and other data feeds, ensuring the reliable ingestion and updating of external data into the Stay22 platform
• Implement and maintain supplier-specific deep-linking solutions to seamlessly redirect users to partner booking pages while preserving a consistent and secure user experience
• Parse, normalize, and store large volumes of listings data (e.g. hotels, accommodations) from external providers to power Stay22's search and booking features
• Retrieve and process booking and commission data from suppliers (via APIs or file exports) and integrate it into our internal reporting systems, ensuring accurate and timely revenue tracking and partner reporting
• Ensure all integration pipelines align with internal data schemas and adhere to best practices for observability, security, and scalability, maintaining consistent quality across providers. Work closely with our infrastructure team to implement robust CI/CD, secrets management, and monitoring for these pipelines
• Collaborate with other squads to maximize the value of integration data - working with the Hub team to support user-facing features that rely on supplier data, providing structured data services to the other product teams, and delivering normalized datasets to the Data team for analytics and forecasting
• Mentor junior developers and new team members, sharing knowledge and fostering a culture of continuous improvement within the Integrations squad. Advocate for code simplicity and maintainability in all solutions, keeping long-term implications in mind
  
  

Requirements

• B.S. or M.S. in Computer Science or equivalent experience

• Deep understanding of modern frameworks and technologies, with a proven track record of delivering high-quality, scalable web services or applications. Hands-on experience with building and consuming APIs and working with cloud infrastructure (GCP preferred) is required. Familiarity with Python is a plus
• A creative mindset and strong problem-solving abilities, capable of navigating complex data integration challenges with pragmatic solutions
• Proven experience in leading or mentoring other developers, with a focus on improving team skills, code quality, and overall product reliability
• Comfort with agile development, rapid iteration, and the potential for significant project changes or pivots as partner requirements evolve
