What you will do

As a Senior Data Engineer, you will be a key player in the end-to-end lifecycle of our large-scale ingestion and transformation engine. You will be part of the full engineering loop: designing, developing, scaling and maintaining our data pipelines handling large data streams - to the order of 100 TB per day. This role combines advanced greenfield data engineering, diving into the complex business of hospitality data domains, and improving, maintaining and supporting the stability and quality of existing pipelines.

Where you will have impact

• End-to-End Pipeline Engineering: Design, build, and deploy scalable data pipelines that ingest data from a polyglot of sources (APIs, Webhooks, SFTP, Cloud Storage).
• Design and implement complex domain modeling and transformation logic to ensure disparate data sources are unified into high-fidelity data products.
• Architectural improvements: the transition of legacy processes and components into modern, scalable and stable data architectures
• Operational Excellence: improve the reliability and quality of our data pipelines by building and improving advanced observability, automated testing, automation and self-healing features to proactively address root causes.
• Collaborate closely with product, other engineering teams, support and business teams, customers and partners.
• Lead the investigation and resolution of complex technical issues, performing deep-dive analysis into our code and systems to identify the root cause of issues in your domain.
• Drive engineering velocity by smartly applying AI to speed up development and leveraging AI and automation to streamline complex debugging, root-cause investigations, and recurring tasks.

About our team

You will join one of the Integration Engineering teams as (one of) the most senior team members. Our mission is to reliably transform, integrate, and store the numerous data sources that power our BI products, from web-scraped data to direct API integrations. We handle a staggering amount of information—our main dataset holds over 3 trillion hotel rates, and we process over 100TB of data daily. You'll join a highly talented and collaborative group of around 6-8 data engineers.
