The Difference You Will Make:

As a Senior Fullstack Software Engineer on the Event Logging team, you will play a crucial role in enhancing Airbnb's data ecosystem:

• Design and build sophisticated internal tools that empower data practitioners across Airbnb to efficiently discover, understand, and leverage event data, significantly reducing time-to-insight.
• Develop intuitive user interfaces and robust backend systems that streamline data exploration, schema management, and data quality monitoring processes.
• Shape the long-term technical vision for our tooling strategy, ensuring seamless integration with our existing logging infrastructure and workflows.
• Lead the implementation of key projects that will improve data accessibility, enhance data governance, and boost productivity for hundreds of data users within Airbnb.
• Collaborate closely with data engineers, product engineers, data scientists, and product managers to identify pain points and deliver innovative solutions that accelerate data-driven decision making.
• Drive improvements in key metrics such as tool adoption rates, time spent on data discovery, and overall data quality scores.

Your work will be instrumental in unlocking the full potential of Airbnb's vast data resources, enabling faster innovation and more informed business decisions across the company.

A Typical Day:

As a Senior Fullstack Software Engineer on the Event Logging team, your day might include: 

• Collaborating with data engineers, product engineers, data scientists, and product managers to design and implement new features for our event data discovery tools, enhancing data accessibility across Airbnb.
• Writing and reviewing code for both frontend (e.g., React) and backend (e.g., Kotlin, Scala, GraphQL, Flink) components of our internal tooling ecosystem.
• Working with cross-functional partners to triage, scope, and evaluate feasibility of proposed features and functionality to enhance our logging tooling.
• Participating in team stand-ups, sprint planning, and retrospectives to ensure alignment with goals and project timelines.
• Analyzing user feedback and usage metrics to identify pain points and opportunities for improving our data exploration and schema management tools.
• Troubleshooting and resolving complex issues related to data ingestion or tool performance, ensuring high availability of our tooling.
• Being a collaborative teammate and mentoring engineers on frontend development best practices and conducting knowledge-sharing sessions on fullstack technologies.

Your Expertise:

We're looking for someone who brings:

• 5+ years of fullstack software development experience, with a focus on building internal tools or data-related applications.
• Strong proficiency in at least one major backend programming language (e.g., Java, Kotlin, Scala, Python) and experience with modern frontend frameworks (e.g., React, Angular, Vue.js).
• Proven track record of delivering end-to-end products in a collaborative environment, from ideation and planning to implementation and launch.
• Experience with architectural patterns of large-scale web applications, including well-designed APIs, high-volume data pipelines, and efficient algorithms.
• Demonstrated ability to make data-driven decisions, articulate technical trade-offs, and communicate effectively with cross-functional partners.
• Passion for creating intuitive user experiences and a keen interest in data systems and analytics.
• Bachelor's degree in Computer Science or related field, or equivalent practical experience.

Preferred qualifications:

• Familiarity with big data technologies such as Kafka, Flink, Spark, or similar distributed computing frameworks.
• Experience with data visualization libraries (e.g., D3.js, Chart.js) and analytics platforms.
